JD 510b - clutch issue

Hi guys - ran into a clutch problem with my JD 510b today. Here’s the story - I hardly use my clutch. I don’t move far and mostly use the hoe for digging stumps and rocks. So I leave it in first gear (4 speed) and only use forward/neutral/reverse. Today I used the machine for the first time this year (haven’t used it since last fall), decided I needed some more speed to move some stone, pushed in the hydraulic clutch, shifted to 2nd, released the pedal and that was it. I have no movement forward or backward. The clutch seems to have a slight chatter, but not often, when revving in gear. And will rock forward a bit like it wants to go when I rev it. But I have no power to move. It’s almost as if my clutch didn’t return when I pushed it in. Clutch petal is free to move in and out and feels the same as it always did. Prior to this, clutch was strong as can be, could run into a tree and the tires would dig till i sat on the axle - been like this since I bought it 10 years ago. Contemplated taking the plate off the bottom of where I think the clutch is but I’m not sure yet how to fill it - I believe it’s a wet clutch. I let it sit for the past two weeks (was on vaca) hoping it would magically fix itself but no such luck. Could the clutch be froze or stuck on the splines from when I disengaged? Or what else? Any suggestions?

Before you start taking apart BIG stuff, crawl under machine and have someone push the clutch in several times till you understand the linkage..
Then grab linkage by hand and see if you can release it out further buy hand...
Mine was doing the same thing a few years ago, ended up linkage had so much buildup of dust and oil/grease built up it would’nt allow it to travel that extra 1/2-3/4 of an inch to release clutch fully...

yeah, I don't have time to look it up at the moment, but I'm not sure you have a clutch as much as a reverser. The wet clutch would be controlled by a valve, that your foot operates, technically an "inching pedal"

But it will be more obvious what's going on when you look at it.

Delmar - your correct, it’s a reverser. I finally got back to this machine and hoping to get this figured out. I checked the linkage, both the forward/reverse lever and the clutch pedal work the valve body on the side of the reverser, so all my linkage is in good working order. The fluid level is also good.
I spoke with a mechanic and he stated he didn’t think the reverser went based on my explanation. Everything was working great, no slippage in the transmission at all. I could run into a tree and the tires would dig holes until the machine was on its axles. Pushed in clutch to change to a higher gear and never moved again...

So I’m back to looking for suggestions - any ideas?

Do you have the drive lock-out buttons on the shifter and/or the loader control? There is a solenoid that disconnects the reverser. Makes it seem like the clutch is depressed. Check that system.

I was hoping Mg would chime in, he seems to be the most common guy to answer these questions about Deeres. There's several more, just a matter of time till somebody see's this.

Do you have the operations and test manual? it will have procedures to check every hydraulic pressure you can think of and many more that you'd never think of in a million years.

Without the manual, I'm guessing. If I have to guess, I think I'd take apart the valve that your foot operates, just based on you rarely using it, and the one time you use it,it seems to "stick". might not even take it apart, operate it repeatedly while tapping with a tiny hammer, or remove the linkage and tap the spool in and out, don't bugger anything up, but work it the full length and tap to try to loosen up whatever might be jammed.

I like your thinking, but a "B" model does not have those.

Bwar77, did the pedal fully return to the upper stop?

I’ll have to check on the lock out valve. But from when it happened, that wouldn’t make sense (but not much does to me!). The valve my foot operates is on the side of the reverser. I can clearly see it move up and and down when I work the clutch. I’ve also tried pulling the clutch pedal up thinking it didn’t come all the way back up as well with no luck. I will try again and make sure. I don’t have a manual. And I’ve tapped the valve on the side of the reverser with a hammer but everything seems to operate as it should. Haven’t tried tapping it though with someone actually working the pedal. Does look like it would be a pain in the ass to remove but I can give it a whirl. Maybe I can even convince our local used parts guy to let me borrow a spare to rule that out?!

If you are sure of the linkage being OK, I would recommend you acquire a Tech manual (TM1468) and a pressure gauge before I would go through the work of replacing things. It could range from a simple clutch adjustment (which requires a gauge) or something more complicated in which you can isolate with gauges. If you are not comfortable with that kind of work, then I would recommend hiring someone who can test these things for you.
