I have an interesting thing happening with my tractor, If I climb a fairly steep 45* incline and push the clutch in while still in a forward gear the tractor will start to roll back but something catches and stop the tractor. It is like when the engine is off and you put the clucth in and tractor rolls back but then let the clutch out and it stops it because it is in gear, except it does this when engine is running and with the clutch depressed. then when I let the clutch out it acts like the gears are in a bind but then releases and takes off. I can go forward and reverse several times and it will eventually quit doing it. It has done the several times. it also did this when I was decelerating in a forward motion. I depressed the clutch and it coasted a short distance and then locked up the tires. It again acted like it was in a bind when I let out on the clutch to take off but just releases and goes like normal. It seems to be making some noise when doing this. Any Ideas out there? Thanks
