In this case my engine was only spinning at about 2800rpm, when in fact most small engines run at about 3600rpm. I check the manual that came with the lawnmower and it does state that this engine makes 4Kw or 5.5hp at 3600rpm.
After adjusting the engine speed up it cuts grass a thousand times better and it drives heaps faster too. You can finf out more information by visiting the link at the top here that takes you to the webpage that has even more modifications that you can do.
This mower is a Honda self propelled lawn mower model HRU216 21" cut
For what its worth 3600 rpm is the maximum rated speed and my Honda service manual warns not to exceed 80% of the maximum speed during continuous operation. That's why the are generally set around 2900 rpm. Running higher speeds will shorten the lifespan.
The engine may develop its rated HP at 3600 RPM, but the governed speed by law for a 21" deck mower is 3456 or less RPM. In most cases the engine should be running in the 30/3200 RPM neighborhood when on high speed.
Lightweight is good and what did I use it for it’s a lawnmower
Thanks mate, really helps me I've had my machine for years and was always happy but recently thought performance was not so good. Pretty sure you are right the RPM needs stepping up.
Many , many thanks for posting this procedure for increasing the revs !I've just bought one of these and they oiled/fuelled it up in the shop , started it and then sent me on my way . This morning ( dry now ) I decided to give it a go , and the revs were quite low compared to my old mower of some 20 years now .......I found the ground speed and cutting torque very poor . So , I've thankfully found your video and made the same adjustments to mine this afternoon . I don't have a functioning tach ( one in the post from Ebay since last week though ... ) but I'm pretty good with estimating revs from years of equipment ownership/usage . Now I'm a happy camper . Why do so many mower sellers not give a damn about service/setup ? They're probably not prepared to move that governor spring . Cheers Mate :-)
As someone else mentioned, 3600 was a common rating for the engine power at 3600 rpm.
Many, MANY thanks!
Great explanation. Very clear. I'll do mine in the morning.
Correct, as per manual max governed rpm is actually 3100rpm +/- 150rpm.
this is an old thread. I just spent $10.00 on an HR214 at an estate sale. The guy it belonged to passed away about a decade ago and it has not been started since. It is a clean mower. The oil looked new. He was a drag racer so I am sure he took care of his equipment. I put a little gas in it and on the first pull if fired up and ran like a top.
Got my mower checked at Honda. It was at 2200rpm , 2 weeks old commercial self propelled . The setting was way too low, so they adjusted it to 4000rpm and said that’s way too high , so adjusted it again to 3200rpm. So if you have a new Honda, I wouldn’t go higher than 3200rpm. 3800rpm will wear the motor out according to Honda mechanics. I haven’t tried my mower out yet, since been fixed. But I’m sure 1000 extra rpm will make a huge difference.
great video...got to the point and drew on real world knowledge. legend :)
Good vid mate ! I was not a mechanically minded as you and I just had the repair shop do it for me but I think Ill have a go next time !
Cheers
I had a honda HRU19R1 mower serviced and it came back with the inability to throw the grass to the back off the catcher so it would start to drop clods when only half full or less and lose power on thicker (but still normal) patches
If it makes you feel any better, I just took ownership of my dads 25 year old HRU216 self propelled as he no longer needs it with no lawn to mow. It still starts first pull (but I snapped the cord). I'm spending about $100-200 on it because it's worth it and still a better mower than our couple year old Masport with Briggs and Straton. I just put a new throttle plastic lever on it, and the screws holding it on whilst corroded slightly on the outside are brand new shiny stainless on the inside(25 years frickin old). That's where the money is, I can pull a 25 year old mower to bits and live near the ocean and the only rusted out nuts on the whole thing was the exhaust shield. That's more impressive than our 10 year old car, or 5 year old door knobs that are inside our house!
Best opening sentence to any UA-cam video I’ve ever seen haha
The engine is capable of 4kw (5.5 hp), but like almost all small engines (and many diesel engines, especially in caterpillar equipment) it is governed down to reduce wear and tear on the engine. having made your adjustment, you get more power now, but you will have it for less time, if that makes sense.
I feel like every Australian is as smart as Tinker Tom on Fallout 4. Thanks for the advice.
great video man!
Adjusting the governor like you did , puts some more pressure on internal gov, bearing. However will take years to whear down. Just FYI.
