Howdy, got a question about the clutch. Okay, it's not a clutch it's belt-drive but still. On my 2005 L100a, the belt grabs way too fast and I do wheelies no matter what. Is there any way to adjust this so it slips a little?

Re: Can I make the clutch slip a little?

Try throttling down to just past idle before letting the clutch pedal up..just enough throttle so the govenor will kick in and not let it stall..then you can rev it back up once its moving..

If the belt is a new kevlar one,they do tend to be grabby until some use and they glaze up a little..
There are things like belt dressing or spray to apply to slipping belts to make them grab better,not less..but oil,or wax,would make a belt more slick and less grabby,but it may also make it slip too much and burn it up faster..I'd avoid putting any of that on it..

Re: Can I make the clutch slip a little?

Is there a belt-tension adjustment? Maybe it's too tight?

As T-H said, I wouldn't try to add anything slippery to the belt. If it's too much, and it starts slipping, you'd almost certainly have to replace the belt, and *very* thoroughly clean all of the pulley surfaces, to remove the lube.

Thanks Tractor-Holic & RedOctobyr, I appreciate your advise. Never thought about throttling it down before engaging the clutch. Good idea! I just bought the tractor and it's supposed to have a new belt on it but I'm not sure what it is. Come to think of it, the belt sleeve came with the tractor so maybe I'll look. Not sure if it has a clutch tensioner, I'll have to look at that too.

Thanks again guys 🙂

Re: Can I make the clutch slip a little?

Just like a car or truck with a standard transmission, control the rate of clutch engagement. Some bite hard, others engagement more softly. You just have to learn how to work yours.

Throttling back is a good start until you get a feel for it.

Re: Can I make the clutch slip a little?

The "clutch" is a tension pulley which depresses on the side of the belt as you let up on the pedal. You've already been told to slow down the rpm's, and I'll add that letting up on the clutch pedal slowly will have the same effect. Just like a with car, there's no reason to "pop" the clutch unless you're in some type of hurry.

Yeah, that's what I've been doing. Trying to let it out as slowly as I could. It just grabs and away we go. Sometimes it works Ok, mostly not. Previous owner said the tractor was sitting for at least a year before I bought it and I'm finding things are all pretty stiff. Doesn't look like it's had any maintenance in a long time. Spindles took 30-40 shots of grease each before I could feel any resistance. Hard to steer until I lubed the front end good. Wheel bearings needed a good shot of grease too. I'm thinking it's just been sitting and will take a while to free up. I'll try to adjust the tension pulley, hit the throttle cable, connectors and other points with spray lube. See how it goes then.

Spindles took 30-40 shots each? That's a lot of grease. Interesting also that you started "feeling resistance" toward the end. Seems like the seals would have majorly blown out long before that point. How much empty space is in those things?

BTW... You say it's been sitting awhile. Is there rust on the pulleys where the belt contacts? I can see where that might be awful grabby...


Overkill.

Easy fix.... Take a block of canning wax and touch the belt. Works great...

Re: Can I make the clutch slip a little?

Some machines require a fabric covered belt. If it has been replaced with a rubber sided belt it is going to grab.

Heh heh... I had to chuckle when I read this. You are not alone and there is no cure. I have an Ariens rider with the exact same clutch mechanism and it works the EXACT same way. My brother has a Deere L-series that is the same. It's almost like it doesn't have a clutch. My Ariens is going on 6 years old and I would have thought the belt and pulleys would have loosened their grip by now but NO. Check YouTube videos of similar tractors and you will see nearly everyone complaining about the ON/OFF clutch mechanism.

I'm surprised there has never been a class-action suit on the tractors that use this design. It doesn't matter how slowly you try to leave out the clutch as anything above second gear results in a violent jerk forward and a wheelie. Throttling down to idle can help a bit but you have to r-e-a-l-l-y feather the clutch.

One time I had the throttle about half way and in 3rd gear and my foot slipped off the clutch and the tractor jerked forward and did a wheelie with such force that I thought I broke my back.

I only use my Ariens as a mail-getter and utility vehicle around the yard and I pity anyone who actually has to mow around obstacles with one of these clutch mechanisms. I wonder how many owners have accidentally plowed into a fence, house or car because the darn think lurched forward when trying to release the clutch?

I was surprised with that many pumps too. I gave both spindles 5-6 pumps to begin with, started it and spun the deck up. Still heard the dry bearings sound. Did another 5, same thing. Then remembered what someone said once about pumping until you can feel resistance. Did that and smooth and quiet. Never saw any grease coming out on top or bottom so no blown seals. Could be my grease gun doesn't pump as much as others do so maybe that's why it took so many.

Good idea about a rusty pulley. I'll take a look. Thanks

Now I didn't plow into the fence exactly, more like a little nudge.

I'm kinda spoiled with my old rider, a Murray Ultra (RIP) with the Hydro trans. You just push the foot pedal forward or back and off it goes. Nice and smooth, no wheelies. I know what you mean about your back though. It didn't hurt but I was sure glad I was hanging on to the wheel!

Re: Can I make the clutch slip a little?

I tell customers all the time that if you have a clutch brake one NEVER use a hydro or auto one...You will never want to use your mower and have to get a new one.
Then I make them feel better---I guess I'm passive-aggressive, by telling them they have the best most durable trans though and they can pop a wheelie every time and they will probably break a belt before they damage the trans. The hydros....not so much.
