*My yard consists of roughly 3.5 acres of "mowable" area with several small hills **Bestfor.Garden** also recommend and valleys and tree-beds scattered throughout. Not only did the mower do a great job, but at the end of cutting the entire lawn, I STILL had 35% left on the battery.*
After cutting 3.5 acres the battery should be 100% charged..

I expect this mower will last several seasons with decent care. ua-cam.com/users/postUgkx1VWTrayKBdCKAjzAcZ_Eg4dhHTae3LkN also recommend Also, I ran across the problem with it not starting the 2nd time I used it. There is a safety switch which is pushed in by the chute or mulching piece being attached to the deck. I took the cover off and it wouldn't start. Put it back on, no problem. It takes only a minute with 2 easily accessible wingnuts and no tools. This mower starts up first crank each time and it is a joy to use. It also mows in reverse by putting the key to the reverse area after starting and pushing in the triangular button. It will stay in reverse mode until you turn it off. All in all, for my homeowner needs, I really like this mower-and at 70 bucks a cut here in Miami, it's already more than 1/3 paid for itself in a month.
Always nice when a manufacturer offers up solid repair information.
Thank you for posting this! Very helpful. Not many manufacturers would post this stuff.Thank you very much!
Thank you for your EXCELLANT explanation. Being trying to figure out engine replacement nightmare for days now. You gave me some very interesting things to check. Again, great job!
Really glad that you care enough to make this video. That tells a lot about your company in my opinion. Thanks Ed Wright
Awesome PK and thanks so much ! Isolated problem to wire backing out of female side blade PTO plug. Fixed !!
Thank you for your response: It was the solenoid went bad. Replaced it and no more problems. Thank you again for your time and knowledge
Wow, glad you were able to get it fixed. -Ed
You sir know your stuff! Very refreshing to see in a young person these days, like yourself 👍🏾
Thanks, we're just having fun. -Ed
Knowledge is power! Thanks for sharing!!!
Really, it is really the professional way to approach something like this that involves so mucho dirt and shades, wires that at least my self only get 50% of the explanation. Pls don't stop doing what u do. JUST , DONT CHANGE ANYTHING. God blesses u. My respects Carlos
Thanks!
Very good and accurate general info.
this is the most comprehensive video tht i have seen, thanks.
No problem. -Ed
My mower won't run without shaking the main body, sometimes it runs for a second, sometiems for a minute if the mower is kept moving, however when it runs around normal speed I can smell what seems like ozone just for a bit then goes away. Mower then stops and it takes quite a lot of shaking to get it to start again. No problem with circuit breaker.
At 17:28 You're talking about the starter in a no crank situation, I think it would be important to mention if valve clearances aren't correct it will keep the starter from turning the motor over. It would cause a voltage drop across the system and have you chasing your tale. Also you can do a voltage drop test at the starter to ground on frame to see how much parasitic voltage loss from a failed ground to frame, whether it's a fraying wire or loose connection.
Finally! A local channel. Represent Frederick!

Great advice here. I’m a Industrial Electrician and obtained a different brand zero turn mower for hardly any money. The previous owner melted the wiring harness and instead of repairing the mower they sold it to me. I got the mower home and troubleshoot the circuits to see if there was a faulty switch or coil. What I am getting to is as in my field we troubleshoot basically the same way and I printed off the wiring diagram and highlighted it like you said while troubleshooting and installing the new wiring harness. My mower has a diode for the clutch like you talked about and I wanted to understand the theory of why a diode was there. Man it’s been 20 plus years since I took electronic classes at tech school. So I did some research and you are also correct about backlash voltage when a high current circuit is opened. Once I read that a 💡
Went off in my brain from tech school years ago. The diode diverts the spike back to ground vs damages to other electrical components. Again great advice buddy thank you.
Thanks for a nice video ad of troubleshooting nice overview you open up an area of space hopefully that mean you can be able to meet each other and visit one-day
No problem, thanks.
Ed, what's your role in the company? In all the videos, you're always diving in head first & getting dirty. Your product knowledge is outstanding. Keep up the good work!
Hi James, My role is VP of Engineering, Sales, Marketing, and Service. I love mowers, using mowers, and the business of mowers and try to bring you the best experience I can. From a young age I grew up around the factory and have been blessed to have learned a lot from many cool people who have gone before me. I hope you have a great season. -Ed
James Culbertson j
Glad, I found the channel, the video quality is great! Have you guys considered tutorial type videos? Simple tasks that are standard between all Wright mowers such; as replacing belts, chaining oil, blades, greasing and other tasks that will have to be completed over the life of the typical mower.
Glad to hear it's been useful to you. Yeah, we have some ideas. I'd like to eventually do videos on almost everything in the owners manual. Thanks, Ed
instaBlaster...
You save me a lot of time and money. Thank You Thank You Thank You
Sure! -Ed
when he says take off your ring and watches it is good advice. My stainless Steele watchband turned glowing red one day on my wrist. I still have a scar from the burn.
Wearing metal jewelry while working with electricity is like duct taping 50 bloody steaks to your body and swimming in shark infested waters. I found that out the hard way. Same with welding, I was too cool to wear a jacket and woke up the next day looking like I shed my skin and grew some scales made out of frosted flakes
Thank you, been so frustrated, this video helped me get back in touch w my inner technician #motivation
Super. Our industry is in need of great technical know how. -Ed
So GOOD I started an account to give it a thumbs up
Awesome video very informational
Thanks.
Great video. Thanks.
I should know all of these things. But yet, I still enjoy these videos.
Edit. Well not an expert with lawn mowers. But I am certified CompTIA A+ and Cisco CCNA certified. So I am really great at trouble shooting and with computers. And plenty of hands on fixing of weedwhackers and lawnmowers along with my business license of landscaping.
Awesome. There are not enough people in this world understand electronics. -Ed
Thanks so much for the very informative videos! I have a ZK and replaced the engine with a new Kawasaki.The problem is that the wiring harness does not match the original.I have most of it figured out but the fuel solenoid.Since you say the orange wire has power all the time does that mean that the fuel solenoid has constant power to it.Thank you.
I watched 1:12 seconds of your video and you were talking about safety while testing this system and being aware the motor may start or be a issue. Disconnect your spark plug boots. I will continue watching the video and provide anymore feedback to your training.
Thanks, Wright.
Sure, glad to be of help. -Ed
Good job i found out i had a lose wire on solenoid
Thanks for the great info Ed.
We have a pro turn 460 and it won’t star. I notice that the two lights next to the gas level won’t light up either.
Any solution to my problem?
Thanks a million
Good job man thanks
Sure!
Love your videos and seriously considering a pair of wrights as our next mowers. Would really like to see the two position pto switch on your mowers, do any of them have that? Its a very convenient feature for jumping off to grab trash or just getting off of the mower. Thanks
Sorry we don't. I don't think they are as safe.
I took your advise and the second thing i check was the Solenoid
Good!
thanks
real good video
have an older wright sentar and the starter would not engage.
so I bought new solenoid and new starter. installed and it engaged and started motor. ran great!
buttoned everything back up,
tried to start and starter will spin but not engage flywheel.
so changed out new positive and new ground cables, checked grounds ( have schemetic) checked harness & cleaned connections. fuses are good. switch seems fine but gonna replace anyway. battery is big strong deep cell usually in boat.
screw driver across new solenoid clicks and spins starter.
any ideas?
Great video thanks man! Can you take the light harness out of a John Deere D170 and it still work and if so, how?
Thanks that really help
Where is the 25 amp fuse or fuses located on the BadBoy Maverick with Kohler engine?
Can you do a video on B&S or will it most likely be similar to a Kawasaki troubleshooting
Good class on electrical theory. Always a confusing subject though. I have a Bad Boy that seems to stall when turning the key. The switch was just replaced and still stalling when turned. The relay was clicking all the time, so I watched a troubleshooting video which led me to the left steering handle switch. I'll check to see what date the battery is and the CCA. This motor is a 27HP Kohler. I would think 350 CCA should be sufficient. Also do you have any videos with showing the multimeter and what your settings are to test certain areas on the harness...thanks
If you take the charge wire straight to the +battery post...do you need to put a diode in to keep voltage from battery going back to the voltage regulator charge side?
My issue is the brake switch I think. Troy Built zero turn ride on. Mustang xp 2009. It starts, blades engage. I turn off the blades put the parking brake off lift the arms and it turns off the engine. Great video but nobody on YOu tube talks about the brake switches. How can I test them?
Are those wire colors standardized over all the different riding mowers, etc?
Hi Edd. I have a problem with my Castle garden tx102. It starts and cuts out after a couple of seconds. It can do this 5 or 6 times then runs perfectly. I'm a car mechanic myself. Choke is perfect. It's a instant cut off. I can send you a video clip if helps. Any help much appreciated Niall.
I’ve had some electrical issues with my new machines a little annoying when you have the lay up a machine when it’s brand new and they should still keep a recoil pull start just for emergency if the battery goes dead once everything is done, you cant Start it that’s annoying I know it would be a little tough to pull start a better motor but it can be done when you’re in a jam
Hi i have a CastelGarden xt 200 hd . It will start and run for about 6-7 seconds and cuts out but it will start straight back up again and do the same thing . I have checked the seat switch and seems fine . what i found is i put the park brake on if will run fine until i release it then it cuts out again . I have a feeling it's the seat switch but it seems ok i think . HELP NEEDED .
Question: Mower won’t start, but if I keep turning the blade switch on and off it eventually starts correctly. Is it the switch?
Hi Ed Thanx for you time your a cool guy too show your skills! Could I Ask you about my Gt3000 25Hp.Kohler Pro-V-Twin Tractor? I just replaced the Engine Head Gasket and put it all back together the way it came off! The Tractor was running before I started. I got it all back together and it will not start the 30amp fuse blown when I put a new one in without key in the switch. I jump started the starter with a scwewdriver and the Engine will run aslong as contact is being made at the starter. With the Key not being in play here why is the 30amp Fuse blowing when it makes contact to the Fuse Holder? Please Help.,Thanx Will!
William, I don't know a lot about your model. It sounds like there is something wrong with the machine side or where you reconnected the engine. Double check those connections.
Hi there thanks for the info, I have a Ariens 60 zoom .it has intermediate starting issues , i puled wire connector off the relay) then put it back on and it started , than turned off a couple of times and it would not start ,so i cleaned cleaned with electrical cleaner , now it wont start . do you think the relay could be bad
Ed, I have a briggs 2100 electric start model motor. How do I connect the battery?
I have a deere 652r with a no start problem. Have had it at deere twice and theyve thrown parts at it new rider present switch new pto switch new brake switch and new relay. Problem still exists. I have found out if i pull the relay, the mower will start then plug the relay back in and it start fine off and on for the next hour then the same problem. Have you ever come across this before? I tried swapping a relay from one of my other 652rs that run fine but it still didnt start. I figured it shouldn't be able to start with the relay pulled. Seems weird. Any thoughts?
Is there any videos showing exactly how to test all these different scenarios? I understand the wiring harness . What i need to SEE is hands on , with the multimeter and why it gets set on certain things for certain diagnositc for one thing and why its changed to test for anotget issue. Looking for a video thats has trouble shooting fron A to Z. Not dogging this video by all means. Great video for learning the wiring harness and components. I need video hands on in real time showing trouble shooting an electrical system for example . He mentiins how to test for the regulator, but doesnt actually test the regulator and stater. I need to see it done from begining to end. As close to me being hands on. Thats the way i learn. I would junp right in but what scares me is hooking things up wrong and frying a component . I need the who what and why for trouble shooting electricak systems for DUMMIES. I AM DUMB. SO NO BEED TO TELL ME. i am tryinv to be smarter though... I reqlly am 😂. Thanks for any leads and info.
Thanks Wright
sure
I have a Koehler 24 hp that charges till engage the clutch for the blades. I have 13+ no blades. Drops to 11 with the blades. Any ideas where to start? Clutch drawing too much amps maybe.
please help with any ideas! my cousin was driving their toro z master zero turn mower with Kawasaki engine and accidentally swamped the deck in their lake. they stopped using it for about a year where it sat idle in their shed. they decided they wanted to use it again, but when I engage the PTO the engine dies I checked the relays and switches they seem fine could it be a rusted electric PTO clutch? any ideas would be appreciated thanks!
Wow, could be a lot of things. I'd be sure the blades are free--maybe they seized. Electrically, check the platform switch.
Sounds like spindles if u swamped the deck while the spindles were hot they sucked up water then u put up the mower the bearings rusted solid so the motor and pto can't spin the belt
Ed. I have a White Outdoor 18 1/2 HP lawn tractor. When I engage the blades, the mower dies. In addition, when i push in the reverse button, it no longer works for me to mow in reverse. Any thoughts? Thanks
Put a new battery on it
Ed i have an electrical problem on my pto swith when the engine not running i have 12v+ to the pto switch but when running the power goes high what would it be?
awesome
Hello I have a craftsman tractor 46inc that starting with a jumper but not itself I think it’s not charging the battery please tell me a idea what can be, the regulator or something else. Thank you 🙏
I have a Kawasaki motor on husqvarna mower. 3 years old. Mowed yesterday loaded on trailer traveled a few miles went to unload and won’t start, won’t crank nothing?
So I had a misfire on my 2017 stander zk, I changed out ignition coils, getting spark but no start at all now. Battery is bad and would only turn over on jumpers. Do I just need a new battery? Also my stator wire going to voltage regulator is a little burnt up. I have spark, fuel is going to carb, what could be my problem?
What happens with the pto switch ring pulled makes things happen..
I have key to on position.. and then pull and push pto..
Engine off btw...
It makes a buzz. Or a mechanical noise.. and then again when u push the pto off again
Do newer engines have points for example a predator 708cc thanks
Great video gave me a good understanding of whats going on but still didn't help my problem, with the mower running and the brake released, when the arms are engaged in the driving position the engine dies, any ideas?
Likely one of the safety switches is faulty, there is one on each of the control levers, under the seat and on the brake. Please contact our service department or your local dealer if you have any questions! We would be happy to help
Take off all the safety buttons or you'll keep having problems most newer mower big and small are loaded with those i took them all off my john deere and craftsmen mowers and don't have any of that problem anymore
Or go buy a bunch more of those cheap safety buttons
Now on my Kohler courage sv725 its purple wire had a orange wire that jumped from it to its own hole on the plug i cut the male plug part off because the engine doesn't go to the sst18 that plastic plugs not needed because of that but thd wiring is thats all sorted out except for the yellow wire on the pto switch now that set of wires goes to the sst18 none goes to the Kohlers wiring but i spliced them into the sst18 wiring
I think I have an issue with my wright RH 48inch mower, it didn’t want to start up too good and when I went to engage blades it stalled the first time so I tried again and it struggled but the blades came on and it ran fine while cutting but kept struggling every time I would go to turn the blades on again, got a little better each time almost like it was warming up and got better as it did....although it was colder than normal (around 45 degrees Fahrenheit) I feel like that shouldn’t effect it if the engine is at a good temperature, I let it warm up at least 5 minutes before activating blades first time. Any tips or suggestions are appreciated!!
You can reach out to our service department here www.wrightmfg.com/contact/
No. People need to know where wires connect. Where does the NEG batt cable connect ? Everyone know there are wires and that they connect. But where ?
Much to digest for a novice but a few GEMS that will be very helpful . Thank you
Glad it was helpful!
hi. does the clutch go bad all at once? On my wright 32 walk-behind, all of a sudden the blades won't engage without any prior signs. I'm guessing its electrical. When I pull the switch the engine doesn't turn off unless i let go of the grips, so I don't think its the pto switch. I followed the wires and nothing looks off. So my question is does the clutch go bad without any signs? the machine is only a couple years old
Thanks so much
It can die at once but usually it dies slowly. More likely it's the blade switch.
-Ed
I have a Troy-Bilt 17.5 IC OHV BRIGGS & STRATTON ENGINE. Check the fuse it keep blowing the fuse. Can you give me insight on what's going on
I don't have a lot of experience with that model. Surely there is a short somewhere. If you can use an ohm meter and check the clutch that may be a good start.
I have a ExMark with 211 hours. When I turn the key switch one it will try to start then the 15 amp fuse blows. Any suggestions as to what it might be?
I have 11.90 volts on my battery should I change it?
Great Video. I have a zero turn mower, last week used mower like usual. All ok. 2 days later mower started with no issue but blades would not engage. Parked mower to look at pto, shut mower off now I have nothing. Won’t start. Any ideas Ed? ThankYou.
Strange. Maybe a grounding or charge issue? -Ed
You could get you a battery charger plug it in the outlet turn the ignition key to on plug the black clamp to any metal on the mower and touch the red one to the red wire on the starter
That'll make it start if something else went out on the mower like the ignition key switch could have a spark box could have could have a loose ground wire or loose to the battree if not doing nothing it can be a burnt out safety button
Ed,
I have a no start situation on my Wright stander x, 5 years old but only 40 hours on it. Parked it and went to start it again and no luck, no sound or click when I turn the key. The fuses are intact and it won’t fire with a jump. Any suggestions?
It's a safety button
Hi I have a riding mower Troy bilt bronco doesn't start when I turn the key the flywheel turn correctly batterie is good carburetor fuel with single solenoid good but it doesn't start can you help me please
Me again Carlos. Is there a way to copy the schematics you used in this lesson ? It is really a lesson. Thks in advance
My respects.....Carlos
Carlos, Each different model has a slightly different schematic. The best thing to do is go to part.wrightmfg.com and enter your mower's serial number. Browse to the electrical page and drill down to the part view of the main harness--that will pop up the schematic for your mower. if you have any issues just select the help tab on the left side of the screen. I'm glad this was helpful! Best wishes. -Ed
What can be the problem when I turn the key and nothing happens no noise or nothing I replaced the solenoid and still nothing
i have a gravely zero turn mower with a kawaski 691 engine it will keep blowing my 20 amp inline fuse sometimes it will run for a while and cut grass after it blows the fuse i can replace it and it will blow as soon as i turn the key after sitting a while it will start then blow fuse again any help is appreciated
Can we jump from the solenoid with the key on
Help! I have no start situation where starter spins but no spark at plugs. Kaw691v engine. Pulled ground off both coils and engine starts. PTO works
Want everything correct.
Sounds like problem in key switch. The contacts are bad
I have a john deer stx 38 installed a new battery , still need to jump it , it is suppose to be for this model , what do you think is the problem ? Thanks for your help.
Maybe the regulator on the engine?
One main thing is a bunch of those new engines and mowers are full of safety buttons when one of those burn out none of that stuff wants to work
Hi Ed, My Scag mower runs fine but when the the PTO is engaged it misfires occasionally and if I run into thick grass it almost dies. Almost as if it is not getting enough fuel or lacks power. I took it to the dealer for service last year thinking it was an electrical issue because it ran fine without the PTO but they told me it needed a new carb...did not solve the problem. I had someone else look at it and they installed new gas lines, fuel filter, air filter and a new Reed. He told me the fuel transfer valve was not working and should be replaced. The mower definitely runs better but still has the same issue when the PTO is engaged. I still think this may be electrical, Do you have any suggestions?
Michael, it's like your health. You can try to describe all your symptoms to the doctor but ultimately you do need to account for your instincts. You are probably right that it's electrical. 1. If you disconnect the kill wire at the engine that will keep the electrical system from killing the spark--just note that this is only a diagnostic procedure you MAY NOT BE ABLE TO TURN IT OFF without shutting off the fuel. 2. It could be a bad coil. When they get hot or create a weak spark they can begin skipping under full load. 3. The ignition power wire going to the fuel valve in the carburetor could be skipping causing the valve to close but I don't think this is likely since what I know of SCAG's electrical systems it's not connected to the clutch in any way. Note that a loose ground will also do this. I hope your issue is resolved quickly--electrical stuff can be mysterious. Whenever we have an un-diagnosed electrical issue pop up as a warranty issue we often advise the dealer to replace the entire harness to insure 100% the problem goes away. -Ed
Michael Pasco where'd the ground wire connect on a troy bolt riding mower
Maybe a loose belt or a weak battery
Engine load increases without increasing fuel to engine will cause it to die. Check governor for correct operation and connection to engine throttle linkage.
smart guy. :)
I have a JD 120 garden tractor(1970), It will start and run for a 2 to 3 minutes and then stops. when I turn the key it will not start. there is power at the battery. Help?
maybe you can help I'm having a problem with my stand-up the two fuses one for the mower deck and one for the starting solenoid are not popping the fuse but melting the fuse after some time
Matt, I've heard of that happening and we are not 100% sure why it occasionally happens. It seems like it might be from the fuses wiggling and fretting.
Cheap fuse holder
@@shakeme3290 yeah the problem was it wasn't a fuse issue for wiring it was a voltage regulator causing me issues
But yeah cheap fuses are an issue sometime to can't stand them
@@WrightMowers yeah the fuse doesn't pop but it kind of melts the fuse
I have a John Deere L110 and the battery drains with the key turned off. My first battery lasted over 10 years. The second battery lasted one year and suddenly died and would not hold a charge. Thinking the battery was bad, I replaced it and the mower ran fine for the 4 hours to mow my 3 acres. When putting the mower away I started it again to confirm the battery was strong. I then turned it off and confirmed the key was in the off position. 10 days the mower would not start, the battery was dead. I charged the battery for 24 hours at 2 amps, but it would not start the mower. What would drain the battery with the key turned off?
Tim, We no longer make any Deere mowers so I can't answer for sure. If I recall they have a red wire that goes from the regulator on the engine to the positive stud on the starter. Check that wire, the main ground wire, and then you may need to check that the regulator is working, which you can do by reading the battery voltage. Voltage should be about 11-12v when off and about 14v when the engine is running. -Ed
Wright Commercial Mowers, thank you.
I have a mower and I have to replace the starter a lot of times because it doesn’t work it’s too sensitive please fix it
22hp v twin cub cadet when plugged up to the main motor harness it gets gas but no fire,,,unplugged it will fire but no gas, unplugged you can run a jumper wire to carb it will start and run fine, but since it's unplugged it will not engage
Don't know a lot about cubs but it sounds like there is something faulting your safety circuit. Check the seat switch, brake/clutch switch, and the blade switch.
hi im working on a custmers husqvarna yth 2348 i have checked th key swich the break swich and ohmed the pto chuch out im completly stumed every time the pto swich is turned on the fuse blows and the mower stalls could a defective seat safty swich cause the short?
Marcus, Hope you were able to get it fixed. I'm not of much use on a Husky. -Ed
I have a Hustler Raptor sd 54" zero turn mower.I have replaced seat switch,park brake safety switch x2,solenoid switch,PTO switch,ignition switch,two relay switches.And I still can not get my mower to start. All it will do when I turn key to start is solenoid clicks.I can take a screw driver and bridge the solenoid it will start the engine. Can someone please help advise me what to do now?
Hi Guys, I need help please. I have a 2007 Cub Cadet Zero Turn Tractor, and all of a sudden when I start it, it starts immediately, then blows a fuse and dies. I have changed the Ignition switch, the starter, the PTO switch, but it still does the same thing. What can I do to sort this out please?
Where can I buy that pig tail? Of the kawasaki I need that
no charge? might mention doing a battery load test by running with lights on and then see if still holding at 13 volts. or use load tester.
Yes, a good way to check charge.
My Scag Tiger Cub isn't starting by key, I here the power to the carb but nothing from the starter and its new.Can send a link to get the harness for this machine. Thanks.
Scag and Wright probably have the most similar electrical systems., but since I didn't make them I don't have the diagrams. You will have to call Scag. I've had to call them before for service questions and you won't find a number on their website. You have to call 920-387-3150. Good luck, I hope you are up and running soon! -Ed Wright
Wright Commercial Mowers thanks a million
You can get everything you need for scag from www.partstree.com
Hey Ed What would make the battery light come on as soon as the blades are engaged?
Probably a bad voltage regulator
@@johnmitchell8925 Thanks for the reply. This comment I made was last year turns out after using a voltmeter it was in the ignition switch. The return back to the battery wasn’t giving the battery a proper charge
What about the mower with out battery and starter. Im having a problem with my scag 48 velocity plus has a kawasaki motor and has trouble when engaging blades everything good until i engage the blades
Probably something with the kill circuit or blade switch.
What makes the wiring a nightmare is safety switches on everything known to man......
were do I get a schematic like yours
