so i had discovered that on the f engine theres a drive shaft that goes into the engine. i removed the shaft because the self propell is shot. i discovered that when i run the engine, that opening where the transmission shaft would normally slide into started leaking oil, i smelled the oil and it smelled like two stroke oil. does the engine lubricate that transmissions shaft with the engines fuel? i for the life of me cannot figure it out because i no longer have the shaft hooked up so im trying to find out if its fine to leave that open and maybe just plug it

Hey man how would i tell the excact year of my mower, i got the same one but idk the excact yesr

You know its a good day when lawnboy uploads

Thanks for a very thorough and informative video. Are you still using Lawnboy equipment ?

I have heard people have a lot of problems where they take off the guard on a trimmer and let the line out really far and it ends up burning up the motor because it's not running a high enough RPM and it's too much of a load they do better at a higher RPM and less load

I got the same one and never had a problem with mine I always run closer to like 40 to 1 on my oil

Try putting some plumbers Teflon tape around threads on oil fill opening to stop leak .

I have a br700, the left rocker keeps popping off. What would cause it ? I keep adjusting valves but runs for 5 mins and then pops off again.

Great video. Very thorough. Thanks for the info. it was very educational and helpful.

I have 2016 HRX217. It was working fine. But after 8 years I took out both of the drain plugs using an allen wrench. The fluid was dirty. I tipped motor on it’s side and put new hydrostatic fluid in. but was not Honda fluid. The transmission would pull the mower forward but not as well as before. To refill the transmission, do you have to remove it and get the large round cover off to refill it? The sad thing is that the mower was working fine until I drained the dirty fluid out. The transmission will not pull forward now at all? Do I need to use the Honda fluid? Can I refill using the drain plugs or will I have to remove the transmission?

You seem to know a lot about this model Lawnboy, I have the same one an R-8237 s/n 9672811. The only difference is the brass hex nut on top of the carb. My problem is low RPM on the normal setting and the weird thing about it is when I shut off the gas flow the RPM increases substantially (to what it should be) for about 30 seconds until the gas runs out. Any idea thoughts you have would be greatly appreciated. I followed your video instructions on setting the vain tension but it didn’t fix the problem. I have broken down the carb completely and cleaned it as well as the exhaust ports. Also cleaned and re-gapped the coil. It starts in 3 pulls.

Actually, the easiest way to do this is to turn the engine until the piston is just below the ports. Then you can easily clean the ports without worrying about damaging the piston skirt. For any carbon that does fall down into the cylinder, just set the mower upright, remove the spark plug and blow into the cylinder with an air hose. Any carbon in the cylinder will be blown back out the exhaust ports.

I have the older version, M21BMR. I was able to get an "update" kit for it which included rear wheels and a replacement tank, along with a rear discharge chute and a mulch plate. Haven't used it in almost a year but it ran well, need to drag it out again and get it going because it cut really well.

What did you have to do to get the fibers that were crammed in there?

Could you tell me what Briggs slow jet will solve my surging issue. Thanks much

No way, he posted!!!!

Great video! I have a 1993 10591 that i just finished going through. These mowers are fantastic and I agree the cut quality is superior to the staggered deck with both bag and mulch. I really enjoy the videos and have found them helpful several times with my lawnboy projects.

Cool vintage mower! Thanks for overviewing.

Clean mower

Welcome back! Nice Lawn-Boy! I have a few lawn boy shorts if you're interested check em out!

I have a similar model . Im scared to trust the oil injection system .

I’ve got leaky axle seals on my hydrostatic transmission just like this. How do you go about replacing the seals? Do I have to open up the transmission case like you did and pull the axle out? Or can you possibly replace the seals without opening the case and pulling the axle?

Hi, I want to thank you for this video. I had to replace the needle valve because of ethanol and I couldn't remember how those black plastic linkages went. I was able to zero in on it towards the end of your video. I was able to get it because of you !! Even 3 years after you posted this. !! Thank you with all of my being!!

When you cleaned the exhaust ports another thing I found really handy is a wooden knife, but u can use a pencil, nice video 👍

Wow excellent video for demo

Does it still surge?

My 10247 runs way better on a Chinese carburetor. Suttle differences like the jet and nozzle are one piece unlike the lawnboy carburetor. It didn't come with a fuel filter in it either. I like oem parts and prefer over aftermarket, but this mower would not run right with oem carb. It would sputter, and not idle correctly. I tried changing the pilot jet messed around with govenor, and it refuses to run right. So the Chinese carburetor is fine for now.

They are called cam followers.

Thank you you saved me!

Thank you for the posting this. I appreciate the detailed explanation on how this all works. I have a duraforce, and have to take apart the carburetor. Needs to be cleaned, and adjust the jetting on it to get rid of the engine surge.

That’s a beauty brother I have the identical machine and it just blew up 😢 it always started first pull I’m gonna rebuild it she will live again 🤙💯☝️

Any tips for opening up the transmission to replace seals? I've got all the bolts out, but it seems pretty stuck.

How was you able to buy a seal

Too much about grease instead of how to replace

4:00 2 cycle engine oil is fine to apply to air filter, says my trusted small engine mechanic

Thanks for the video, but FYI it's 0.030 inches, AKA 30 thousandths.

Is that a 19inch or 21 inch? I have a 19 and I would like to get a bagging kit for it.

I also would use Briggs and Stratton low smoke 2 cycle engine oil 🛢.

I recommend using degreaser for your Lawnboy mower man, Keep up the good work man

I have a 1990s 10515. Love it. All 4 wheels were wobbly. The wheel bushings get worn out causing wobble. Wheel wobble is unacceptable on rear wheels because it will ruin the self propel gears. Partstree does not sell new bushings. I bought some steel spacers at Lowes and hacksawed to correct length. Problem solved. I bought spacers 1/2" ID x 5/8" OD x 1.5" long and cut to length, about 5/8". Used a file to file down rough edge after cut. They fit perfectly inside the wheels and eliminated wobble.

I have this model. Wheels stopped turning in all gears. After hours of diagnosis I finally traced the problem. The gearbox's left bushing for the driveshaft is worn and the bushing's hole is enlarged about 1/4", allowing the gearbox to move and therefore the gears to disengage. I don't know why the bushing has so much wear; possibly the shaft has rust where it enters the gearbox. Something to keep in mind during maintenance.
