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.
I'm amazed that mine hasn't broken a belt yet. You would think all the jerky take-offs would be hard on the transmission as well. I mean, the transaxles on these low-end machines aren't known for being overly robust.

I had a 6-speed Toro rider many decades ago and the clutch on that was silky smooth. So why can't the newer models work that way?

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!
Like I mentioned earlier, this Ariens is just my yard utility vehicle. It doesn't even have a deck on it. My mowing machine is a JD X500 and yes, the Hydro is nice for mowing.

The majority of these deck have sealed bearings. So all you are doing is filling the spindle cavity between the two bearings full of grease. That is why it takes so many pumps initially. It still blows my mind why they even have grease fittings.

I had a JD 175 Hydro that I bought new in the 80's. Despite greasing regularly the spindle bearings went out in short order. I replaced them and the new ones only last a couple seasons. When I replaced the bearings the third time I removed the rubber seals on the side that faces the grease zerk. 23 years later when I finally sold the tractor those spindles were still turning nice and smooth. Bottom line - the grease in those spindles probably isn't doing anything unless you have one of the very rare decks with open bearings.

Good idea about a rusty pulley. I'll take a look. Thanks
If you leave the mower sit out the polished surfaces of the pulleys will accumulate surface rust very quickly but it cleans off within a few minutes. If I leave my Ariens out overnight, the next morning even 1st and 2nd gear take-offs are jerky but only the first time. I've looked underneath and you can see surface rust speckles on the shiny pulley surfaces but it goes away quickly once you shift gears and use the clutch a couple times.

Heh, that's me. Mine has a clutch and 6-speed, but a foot-controlled hydro seems like it would be much easier and quicker. Especially in areas that require changing between forward and reverse multiple times. At least my machine is old enough that it doesn't have a reverse mowing lockout feature.

The clutch on my machine is a gradual take-up, at least. There's a good chance it's on the original belt. Never occurred to me that some would jerk hard every time they engaged! Glad mine doesn't have that "feature".

Re: Can I make the clutch slip a little?

Some machines had a "shock absorber" type of damper on the clutch idler pulley mechanism so the belt got tightened more gradually and not jerk the machine when you let up on the pedal,it also dampened any oscillation that developed in the belt due to a hard spot or a kink in it..

Some designs of clutch idlers are just "grabby" by nature it seems...rust on the pulley sheaves can also cause grabbing and wheelies..sometimes the brake might be dragging and that can encourage it also..
I can see where a grabby clutch can be a pain,especially when your doing some tight manuvering and need it to engage smoothly..I have a retaining wall along my driveway about 2 feet high I have to mow next to and I've had a few close calls when my Sears Suburban's brakes weren't working well and the belt liked to grab !..almost went right over the edge a few times..

I want one of those shock absorbers. I've got two spots where I have to mow up to a gate, then make a tight turn reversal. Have to do this 2-3 times to get it done. The grabby clutch definitely doesn't help. And I suppose what TobyU said is true, once you've had a hydro tranny it's had to go back. Still, I love my JD.

They make those " small shock absorbers" in a variety of sizes, you may find them in the McMaster-Carr catalog.

Thank you Gary RC, let me rephrase the question. Do you or anybody else know what those shock absorbers are called? And if you do, do you know of a rider that has one on it so I can look it up on that model?

Also, in some previous post a guy suggested I put some canning wax on the Belt and that would cure the problem. I used to do that on car fan belts to stop squeaks and it never hurt them but I'm not sure about my riders drive belt. Any opinions?

Re: Can I make the clutch slip a little?

The idea makes me a bit nervous, but I've never tried it. Wax seems like it might be difficult to remove, if you didn't like it.

Is it definitely the proper type of belt? Such as fabric-wrapped, as was mentioned?

Yeah, I couldn't find the belt sleeve so I don't know. The guy said he put a new belt on it last year but It's looking a little ratty to me so who knows. Or is that a sign that it's fabric wrapped maybe?

Re: Can I make the clutch slip a little?

Did you buy the tractor new...and it always had that problem...or did you just get it and it is like that?...someone may have replaced the belt with one that could be just a half inch too short,,,check what is on there and see if it is actually the specified belt

I just got it and that's the way it is. Trying to figure it out cuz It's really a pain. Possible belt too short? Hmmm, I don't know, I have to let the clutch pedal almost all the way out for it to engage. Wouldn't a shorter belt engage sooner/with less pedal out? Seems logical but I could be wrong. Not sure how to check the belt on it to see if it's right either.
