no high gear

As others have noted, your clutch is slipping. Most likely this is caused by the clutch disk wearing out, which means replacing the disk, which means splitting the tractor in two. A while back there was a mechanic here who was bragging he could do a clutch in six hours. I think that's under ideal conditions, with a well-equipped shop and on a tractor he was familiar with. I think an experience mechanic with the right tools could probably do it in under twelve even if not familiar with the tractor, they're pretty straightforward. In terms of parts, I did the clutch on my Jinma last summer and it was US $155 for new disks for the drive and PTO clutches, and a new bearing. So the cost of the job is mostly labor.

There are two other possibilities. One is that the clutch is misadjusted. What that means is when you take your foot off the pedal, the pedal is actually still pressing slightly on the clutch. The clutch pedal moves a fork which presses on the clutch bearing, the clutch bearing presses on the clutch release. There should be a gap of about 2.5 mm between the bearing and the release. There is an inspection plate on the side of the housing that you can take off and look in to see the gap, but you can sort of tell without even looking there, the pedal should feel like it has maybe 20mm of movement before it does anything.

The other possibility is your clutch is slipping because it is contaminated with oil. To fix that you have to find out where the oil is coming from and fix it, it could be anywhere. I've had clutches where the oil burns off by itself, but it may also mean splitting the tractor and replacing the clutch.

Why would it do that over night I stop for about a hour or two while I was moving the rock and it worked fine

That would be consistent with an oil leak. I had a car once that had a slow leak on a transmission seal. It drove fine, except for first thing in the morning when it had had time to leak all night. There was a big hill near my house, and when I went up that hill in the morning the clutch would slip until all the oil burned off. Then it would be fine for the rest of the day. It was bearable for a while, then I eventually fixed the leak.

A number of owners of Chinese tractors have had issues with inadequate assembly at the factory resulting in oil leaks from either the main bearing seal or the oil sump-to - lock joint. Either one can result in oil being drooled into areas where it gets on the clutch friction disc. The only cure is to split the tractor and clean everything up, replace what you must, and reassemble properly with everything torqued to spec and sealed as appropriate. I did my tractor and everything has been fine ever since. Took me a weekend to split it and get things done right. IUf I'd had assistance I think I could have done the whole job in one day, but working alone took two days.

As others have suggested in could be oil getting on the clutch plate............Feel at the bottom of the bell housing (The big casting that the engine bolts to ) there should be a small drain hole there. Just check with your finger if the is oil present there. If it is you all most certainly have an oil leak inside there somewhere.

Will have a look at that zonat223 and let you no if there is any oil in there if no oil means clutch is gone either way the tractor has to come in half to fix it right

Heat.... Things expand with heat and it was just enough to "adjust" the tolerances.

I actually doubt its oil. Usually oil or grease has the opposite effect than you would think and makes it grabby.

Listen to the advise you are getting. You have a damanged clutch.

I would have a quick look to see if its adjusted correctly you may be lucky...............but honestly think you will probably have to split it.

If you are one of those who simply cannot take his foot off the clutch, the drive disc is in almost constant contact with its pressure plate. Decreases drive clutch life is inevitable. Moving that material was probably all it took to burn off any effective surface left on the disc. I'm gonnal speculate that you'll eventually find the surface of that disc to be be ringed in dark brown to black and have a glossy appearance. And as stated, oil will saturate the friction material and often cause it to separate from its plate. Smooth oily surfaces and/or missing material is what makes an oily clutch "jump"

Have not been on here for a long time just thought I would let you all no that the clutch was not burnt out or oil on the clutch .The problem was that the 4wd leaver had broke and half in 4wd and half in high gear so there you all go
