Awesome to see these type of vids Woody. You boys been busy at Rocky Nats (young bloke and I was stoked to see you there also). Love the weekly content👌
You can multiply clutch capacity by parallelling them. Some helicopters do this. Output shaft with multiple clutches. Counter shaft with identical sprockets and chains. Slightly different engagement speeds can be an issue, but in this application I don't think it would be a problem.
I love the SuperCox! Doesn't seem very safe, too much power for it's drivetrain, no suspension, what an epic fun dangerous little vehicle. It's like Florida man antics in Australia, I love it.
Play with the sprocket ratios as that gearing is way too high as that motor should be able to spin the wheels on a standing start on the grass and bypass the governor for some top end and that mower will surprise you. Loved both vids.
@@theskidfactory its geared too high, the clutch isint getting to an actual engagement point where its not slipping from being so high geared. that engine will spin tyres on grass no problem if you gear it down.
@@theskidfactory yes, even though it has the torque, by making the gearing shorter you will lighten the load on the clutch and fully engage it. At around 8:31 you can hear the revs fall even though you are still accelerating thats when the clutch fully engaged. Just give it one more shot with a much shorter ratio it´s an awesome mower! Love your videos!
Deflate the rear tyres, cut some pieces of thick pvc pipe to fit over the rear wheels and then reindlate the rear tyres to wedge them on. Then you've got a drift lawn mower!
Similar to what some are suggesting already, I'd look into adjusting pulley / sprocket sizes if you plan to stick with a centrifugal clutch. Doesn't look like shrinking the sprocket on the clutch side is very feasible, so I'd personally be looking at possibly putting a bigger sprocket on the output shaft of the motor to trade away some torque (which you have plenty of) in exchange for some more rpms. Love this little thing either way! 10/10 would own!
Sure, there are a few things in the world that we as people don't understand, but how can people not get what's going on here. It's a couple of mates, in a Shed, doing random stuff with a bit of Lemon Squash chucked in for good measure. Loving the content and have always enjoyed watching the videos, with a fresh Lemon Squash.
12:39 ah yes, over before you wanted it to be. That brings back some memories. I don't remember the smoke from my experiences...but perhaps the unusual smell though! 😄😄
Wine and toast Possibly the most entertaining theory dates back to the 16th century from the Roman practice. One of the first written accounts of it was in Shakespeare’s The Merry Wives of Windsor when the character of Falstaff demands “Go fetch me a quart of sack; put a toast in’t.” To translate, he’s asking for a great deal of wine with a piece of (literal) toast in it, which was a common practice at the time due to the poor quality of wine. Thus, placing a piece of toast within a jug was supposed to soak up some of the acidity and improve the flavor.
Sounds like the gearing is too high, ild assume the vtwin would get up to 4.5krmp, ild be swapping the rear sprocket on the rear diff to something twice the size.
There are multi-plate clutches for JR dragsters and whatnot, Bully clutches. They’re centrifugal and dry, and they are what you need! Adjustable engagement rpm and they lock hard as
Just an idea that mates and I have done previous with karts and fitting cheap Honda clones, Briggs and even some v-twins... look at cvt clutches, will handle power no problem and acceleration is incredible. Great work anyway guys making some fun stuff from easy to get components
Classic. All the experts are in the comment section! Just had a read through.... can only imagine how frustrating it must be when you post a video for free and every Muppet criticises how you "should" have done it. Maybe they should make their own channel and show us how it's done!? Keep up the good work you two. Love the work. 👍
In regards to the clutch/gearing comments, you can also see the mower lurch right after start up with little rpm. It's trying to engage at idle as well.
That thing needs a turbo, full EFI conversion, a 3 plate clutch and a 6 speed transmission. Just so you can absolutely dunk on the Nugkart :P Also I want to see the Hoff's face when you bring it in for tuning!
The caster is to help lift a rear wheel to stop it push on under steering like a solid axle causes. Cool little project. Ignore the naysayers though. It’s fun that’s all it’s meant to be 👌🏻
No need to worry about what people say about what you want to build in your shed. Yes i do have a banshee motor but it's in my kx500 frame sorry guys, keep up the good work 👍
Yeah, this you should probably put a CVT on it! There’s some cheap ones out there that’ll probably work better than the traditional friction clutches. Great work though, it’s good fun!
Absolutely loving these vids! The old Cox looks and sounds awesome. Just a thought on the clutch issue. Maybe you could run the clutch on a jack shaft. That way, you could gear it so that the clutch is actually spinning faster than the engine, and engages quicker so you don't smoke it so quick. Whatever you do, I really hope you can make it work with that old mower motor. Keep up the great content guys!
the fact people are still judging what others do to this day is bloody sad! two bloke's in a shed making content for all of us and you are all complaining! great work fella's keep doing what ya doing!
You should use a CVT or Torque Converter like ATV's. Had a similar dilemma with a crosscart build, fried clutches for breakfast. Switched to a Torque Converter, now it can wheelie ;)
Al's summation of caster was spot on... Might add a touch of stability. Adding a touch of camber (2deg max) will help add additional contact patch on the outside tyre if you ever manage to corner hard enough to induce sufficient tyre roll... Ain't gonna matter for shit in this application though :-)
Need to increase the gear ratio. Although the motor has plenty of torque and will easily drive the mower with the current gearing, the weakest link is the centrifugal clutch. To reduce the amount of torque required by the engine (and therefore clutch) the gear ratio should be increased. Either reducing the front sprocket or increasing the rear sprocket will do this. Without doing the calculations unfortunately you will have to keep burning clutches till you get it spot on. I’d be happy to do a few calcs for the gear ratio if you need. Love the videos as always! PS. Your merch is quality👌🏻
You can get mutil disc kart racing centrifugal clutches in different sized bores to suit different crank OD's. Designed/work a bit like a slipper clutch in drag racing.
Not sure if its been answered but anyway. Castor and Akerman in a go kart is (overlay simplified) what allows the rear axle to act like an LSD. What you want to achieve is the inside front wheel jacking so that the the rear inside wheel unloads as you apply more steering input. This removes load from the inside rear and prevents the massive push understeer your dealing with. Woody send me a message if you want some angles and dangles to cut and shut if you want to F-around with it more later :)
Maybe if you adjust/remove the governor and change the gearing. It may improve things. higher rpm should help the clutch and also lower gearing would help it not lug the engine so much. Thee other thing is maybe another type of clutch would work better, like one where the friction material and the weights are the same material. Nice work on the build, looks like a lot of fun.
That new clutch was bang on but the ratio of your drive needs sorted. smaller sprocket on the engine or larger on the rear. The gearing seems to be set up incorrectly. Most of these centrifugal systems like anywhere from 5:1 to 5.5:1. Good luck!
Ooo banshee talk at the end. Yes sir me boss n work mate jad them in 2003 n had nitrous kits hooked. 35ho stock 370cc n nos 137hp. Things where killa 🤙
The Skid Factory just hot a free mower .so may be their will be a super cox in my life lol i may let yee all know ill not be using a clutch (learned the hard way 2) here {USA} any thing that can do 15hp or more is stupid expensive ill be using the belt slip method now i love it be blessed guys much love
Running more caster with the solid rear axle gives better turn-in, because it unloads the inside rear wheel. Karting 101 ;) You can get a similar result by leaning out on turns. Probably easier :D
THANK YOU FOR THE VIDEO Look at put bike setup clutch into wild red thing see a run lot better know that centrifugal clutch will not take the heavy load on burnout and slip
I reckon it's a case of the type of clutch you've used are to suit a higher revving go-cart type motor, as opposed to the V-twimnKohler you are using that is much lower revving. At lower revs there is less centrifugal force to engage the clutch, hence slipping and burning. I suggest getting an industrial centrifugal clutch to suit the revs and torque you are working the Kohler at, max rpm is probs about 3500, torque about 75 Nm.
Those clutches were obviously only made for slow cutting grass speeds but testing something and seeing it smoke 💨 awesome back to the drawing board mates. Belt driven or see if there’s a way to use a motorbike clutch maybe 🤔 hopefully you guys figure it out 👍
Easy to get here in the northern USA but probably don’t have many around there but an 800 2 stroke snowmobile engine would be pretty sweet, 150 HP, excuse me, 110 KW with CV clutch . That should be able to melt the rubber off your Cox!
You guys should either turbo that mower or supercharge it, once the clutch issue is resolved of course 😉 hahahaha. Love your content boys keep up the great work 👏 👍
Interesting story, but I acquired an '85 riding mower from the neighborhood 86 year old hot rodder who was selling it for parts, as it has a very very rare (for good reason as it turns out) actual pressure plate clutch on it that hasn't been made for at least 20 years. I took it upon myself to engineer a new full carbon clutch disc which took a few iterations to build one strong enough to handle what I thought was a fairly trivial amount of power. After doing a few weeks of looking for suitable rear end replacements from ATVs to mini trucks, I had no idea 'til later on that the mower transmission is converting that trivial 11hp engine into 250ft lbs of torque to push around a 600lb mower and needed quite a lot of strength! The one that finally worked was 9" in diameter, has a silicon carbide top face for friction material and mounts to a flanged v-belt pulley to utilize the original transaxle, which after a successful engagement and a mow, the transaxle now needs a rebuild! The clutch came out a little _too strong_ . How often is that a problem?! 😁
It is what it is www.TheSkidFactory.com
Awesome to see these type of vids Woody. You boys been busy at Rocky Nats (young bloke and I was stoked to see you there also). Love the weekly content👌
What it is....... It's Cool. My favorite UA-cam channel. When are you guys coming back to the states?
You can multiply clutch capacity by parallelling them. Some helicopters do this. Output shaft with multiple clutches. Counter shaft with identical sprockets and chains. Slightly different engagement speeds can be an issue, but in this application I don't think it would be a problem.
It would be weird if it was was what it was not.
It could be what it was but it isn't....but it will be what it will be only when it is. And along the way it'll still be cool.
Should use a “torque converter” twin clutches like snowmobiles
Still sick little machine
440 Fuji two stroke perfect 👍
I was wondering about that too but I'm not sure the engine spins fast enough for that.
that's gay
yeah get a CVT
You can change the weights and springs to adjust for the rpm.
guess how many snowmobiles are in Queensland, let alone Australia... good idea though
I love the SuperCox! Doesn't seem very safe, too much power for it's drivetrain, no suspension, what an epic fun dangerous little vehicle. It's like Florida man antics in Australia, I love it.
it's like ozzy antics in Oz....

Exactly what I thought, make the gearing shorter and surely it'd rip
What do you mean? Because the engine has tonnes of torque we should gear it so the engine revs higher? That makes no sense to me.
@@theskidfactory its geared too high, the clutch isint getting to an actual engagement point where its not slipping from being so high geared. that engine will spin tyres on grass no problem if you gear it down.

Needs a bigger rear sprocket to get it doing some skidz
Deflate the rear tyres, cut some pieces of thick pvc pipe to fit over the rear wheels and then reindlate the rear tyres to wedge them on. Then you've got a drift lawn mower!
YES, PVC drift !!!! Japanese style
Since when did the Japanese invent PVC drift?
Noriayro did a video on it
@@theskidfactory Sounds like maccas trays with more steps
It looks like you need to drop the gearing down a tooth or 3. A Yamaha TZ350 would be cool in it.
you need those exaust tip flappy cover things like an old farm tractor to complete the look. I love it!
Cleetus's team stopped fitting them

I love that you show your fails. Keep on killing it.
Helmet, Woody! I was worried for you with the twitchy steering. The Cox is a scream though. Brilliant!
It is what it is, and even though it wasn't very functional it was still absolutely glorious.

I like this intro better than the shortend one
Cheers man, I’ve been swapping and changing them between each video
12:39 ah yes, over before you wanted it to be. That brings back some memories. I don't remember the smoke from my experiences...but perhaps the unusual smell though! 😄😄
Enjoyed the mower immensely. Those centrifugal clutches are fitted to loads of twist and go scooters. Mick Thurston
I'd definitely like to see this project to get fully sorted out. Backyard karts are a blast.
You're dabbling in Grind Hard Plumbing territory here.

Yeah looks like gearing is too long
This was my thinking
Yup, yup, yup! I was gonna write something about mechanical advantage and gearing but screw it, you were first.
Definately need shorter gearing.. or atleast double of current sprocket ratio
13:31 Al just took an obscure yet intriguing turn..
Just getting woody and the supercox in frame
There are multi-plate clutches for JR dragsters and whatnot, Bully clutches. They’re centrifugal and dry, and they are what you need! Adjustable engagement rpm and they lock hard as
I think the video had the most views because you did a crazy build and something people could (potentially) do at home
Love the dedication to this awesome mower
skitz project. nice to show how stuff doesnt always go as smooth as we want. thanks for sharing🤟
I love your videos. Keep up the good work. I recently purchased a mower to make faster and lower it and ride it around for next summer.
Just an idea that mates and I have done previous with karts and fitting cheap Honda clones, Briggs and even some v-twins... look at cvt clutches, will handle power no problem and acceleration is incredible. Great work anyway guys making some fun stuff from easy to get components
Best sketchy lawnmower channel on the internets.

Someone from England got cranky 😄 that’s what we’re good at in England.
This is what skid factory fans have been waiting for.
In regards to the clutch/gearing comments, you can also see the mower lurch right after start up with little rpm. It's trying to engage at idle as well.

Awesome work
To tall on the gearing 😉
Would have been the icing on the cake had Woody been chased by an Angry Cassowary.
Only an angry bush chook where we are.
Yeah, this you should probably put a CVT on it! There’s some cheap ones out there that’ll probably work better than the traditional friction clutches. Great work though, it’s good fun!
Love it boys 👌 Micks a champ. I reckon go the WR 450. Love the sound of this thing though
Absolutely loving these vids! The old Cox looks and sounds awesome.

Who can be negative about such a fun project
Why do I love this more than your epic builds, the same when nugget made a turbo shifter kart
Skid factory is the Best mower racing channel on the internet ..go super-🐓
Al saying goonbag and fruity lexia has made my day ahahaha
was never gonna work, so glad you bothered to try 👌
Great vid don't give up loving this series
10.20 in you Awnser your camber reason , also more fun trying to keep straight haha love it
Love you guys :D
Forget about the knowitalls, just do what you are doing best and keep having fun! :)
the fact people are still judging what others do to this day is bloody sad! two bloke's in a shed making content for all of us and you are all complaining! great work fella's keep doing what ya doing!
Such a sweet ride. Lol. Thanks guys.

Sick mower action, awesome episode
Try a cat from a big engined snow mobile, that should work better than the centrifugal clutch you’ve tried to use. Great video love the “Super Cox”
The Skid Circus. Get a big red nose. FANTASTIC.

What do I win?
I know nothing about it but it looks like fun and bloody cool
Sometimes things doesn't work as planned but at last you had fun so everything's all right.
Can't wait for the next episode.
If there’s anything that anyone ever deserved, it’s a banshee engine. Al deserves one. The universe needs to give Al a banshee engine
Awesome content! Thanks for posting.

chuck a CBR 250RR motor in it and embrace the 20,000 Rpm Red Line
Love the super cox, I'm sure you get it sorted!!
Cheers mate 🍻 🍻
Love it boys, could you reduce the size of the drive sprocket to gear it down slightly, may effect top end but also reduce the effort to drive
