I want to start off by saying, I’m no mechanic but can do basic maintenance.

I went out to get the tractor to cut wood for my grandpa and after letting it warm up I went to put it in gear (pushed in clutch then pushed forward on the forward/reverse handle) and the handle wouldn’t lock into the forward position or the reverse position. If I push forward or backwards without using the clutch the tractor will move back and forward. This has happened before, a long while back, and after sitting a couple days I went back to look again and it operated fine.
I would ask my grandpa but he’s 87 and I didn’t want him coming outside to mess with it in his health. Any info/advise is greatly appreciated.

He has a smaller tractor I’m going to use for now but I’d like to get the bigger one going again.
 
Sounds like the clutch may be stuck. Maybe work the pedal and side step it a few times from fully depressed and let it pop. If it is where you can do it, start it in gear and work the clutch while it is moving. Be careful though because the only way to stop it if it cranks in gear with a stuck clutch is cut it off. May not be the problem but I have seen that happen several times.
 
Thanks for the quick reply fellas. I just tried popping the clutch and tried working the clutch while moving forward and reverse with no luck.

I hope this next park makes sense.

There are 3 “gear sticks”.

1. Rabbit/turtle (hi/low)
2. 1/2/3/4
3. Forward/reverse

The only way I can get the tractor to start moving is to put the hi/low in neutral, then pick a gear (1-4), and then pick forward or reverse. Then I can move the hi/low knob into low gear and it will take off. Once moving the clutch still doesn’t work and I have to pull it back out of gear to stop or turn the key off, of course.

Could this be from a low oil level?
 
Check your clutch linkage to be sure it all looks to be moving correctly and nothing has came loose underneath that would cause it not to function. Many tractors also have a access cover in the bell housing you can look in with a light to see whats happing inside it as well to see if clutch is releasing. If all that seems to be function it might have to be split. I doubt it has a hydraulic clutch like a truck but it would require correct oil and master/slave setup to be working correctly but most tractors are mechanical I have seen.

I did look at it spec wise it list the m8200 as a hyd clutch so it would not be out of the question to have a master slave setup or reservoir feeding it. Didnt think kubota went to the hyd clutches till the newer models but was wrong.
 
Just saw that this is a hyd clutch. Does the clutch pedal feel normal when you depress it? If so read on. If not check that first.

Typical clutch set up is an input shaft into the transmission or gear box as the case my be that is splined into part of the disc. This disc is captured by the pressure plate which causes the tractor to move when the clutch is released. When the clutch is depressed the pressure plate is moved off of the clutch disc which allows it to slip stopping the movement. If depressing the clutch does not stop movement then the pressure plate and the clutch disc are still connected.

100 years ago we sold small track machines called Bombardiers (no idea if it is the same company now a days that makes the snowmobiles and jet skiis or not). They sometimes sat on the yard a while before being sold and the clutch would stick. Solution was to take them out back and run into a tree with the clutch depressed. This would sometimes free the disc from the pressure plate. Would not recommend this for a tractor as these things were built like a tank and could take the abuse. If you have an implement say a box blade for instance you could try driving it and dropping the blade suddenly to stop forward motion with the clutch depressed. This might shake loose the clutch disk.
 
Just an update, I had no luck and my grandpa called the local tractor shop and they came to get it. Hopefully it’s nothing crazy expensive. I try to do the basic pm’s but I am no mechanic.

On another note, as my luck would have it, his smaller tractor had a leak in one of the front tires so I pulled it and found a leak in the valve stem. Got it fixed and put back on but man they’re heavy. It was partially filled with liquid which I didn’t realize at first.

Thanks again to all that mentioned things to check.
