OK got my tractor home runs good. I think he said it's a 1967. I can put it in gear, then start it & it goes but nothing on the pedal. If I push on the clutch pedal it makes a bit of a grinding noise. tried to set it up for an inch or so free play. but still nothing when I step on the clutch. Tractor keeps going. Have to turn ignition key off to stop it.
Could it be the clutch release bearing? or the yoke the holds the bearing?
Any and all suggestions welcome.. And it has hydra power & that works good when It's going, shifts in & out fine. This is my first Cockshutt so I'm in strange territory.
thanks in advance
 
I had my clutch stick before if tractor sat for a long time. I drove out in an open field and held clutch pedal down and stepped on brakes plus went up a hill and it let loose. Greg
 

Thanks I will try that.. The guy I bought it from said it just happened one day. but it did sit for awhile. He only used it to haul the odd bale of hay..
I just called the guy & he said the clutch sticking did happen to him , but this time he was using it & he stepped on the clutch to stop the tractor & nothing happened, although he said it could be a sticking clutch. He didn't know..
Also the pipe that screws into the exhaust manifold & the muffler goes onto is too small. Does anyone know the correct size of pipe & thread that I need.
 
Doesn't sound good but maybe all it needs is some TLC tools labor and cash! On the post about 1655 clutch replacement down below has suggestions that would apply to your 1550 as well. Just remember to pull the long PTO shaft out the back of tractor first. Does it have hydra power drive? I think the exhaust pipe is 2 inch black iron standard pipe thread on mine. Good luck Greg
 
If it's not a stuck clutch,it could well be the fork. Mine broke one time. Another thing that happened,I have a loader on a 1600 and that one did it. The fingers were worn off the pressure plate on that one.
 

Thanks all for the replies.. I will try the cheaper ones first like trying to see if the clutch is stuck, if not I guess out she comes..
 
I'm right in the middle of putting mine back in right now. Just stopped for some lunch. Got'er sitting back down in the tub. I put the one back in the 1850 this morning.
 

Did you replace clutch & pressure plate? & reface the flywheel?
How long did it take you to do it?
 


I guess old age is catching up, but for the life of me I don't see the thread of Super 99 & sticking clutch..
Also is this quite common, I've had lots of tractors, but never Oliver or Cockshutt, & I've never had or heard of a sticking clutch.
 
I just had the clutch refaced. The reason I tor it down was because I spun a main bearing. Thought I'd better put a new pilot bearing in and have the clutch refaced while I was at it.

That said,DON'T Do What I just did! I've got it all back together and have to take it all back apart again. The throw out bearing must have slid ahead on the tube when I was moving it around on the floor,and slid out of the fork. I was all done,had the tools cleaned up and put away,had already started it up three or four times,adjusted the tappets,the works. I pushed the clutch pedal down and had no resistance at all. OK,don't panic,new clutch,adjust the linkage. Didn't do a bit of good. I started it in gear and can't stop it. It's gonna sit til I'm done filling silo now. I'm done messing with it.
 

Oh OUCH, that hurts.. Thanks for the heads up... I will watch for that, & hopefully not do it,,..
When they say to pull the PTO shaft out, are they talking about the PTO at the back with the spline & you hook up a mower etc to it.. When I look at the PTO it seems way below the motor. How would that affect pulling the motor out?
 
No,not that splined shaft. The one above it that drives it. It has to be pulled out two feet or so,so it's past the chain coupler in the drive shaft. There are three bolts that hold the bearing in there.
