Posted here a few times since buying my 1980 B7100 in Dec. Previous owner (owned tractor for 20 years) said he thought the clutch was worn as there was no adjustment left on the actuating rod from the pedal. This is true, all adjustment has been used up, but there is absolutely no free play either. Clutch does not slip at all when pushing a blade full of wet, heavy snow. I start the tractor in Neutral with the clutch depressed, release the clutch & let it warm up for a few minutes at 1/2 throttle (or less) while I clean off the vehicles after a storm. When I get ready to plow/blow, I throttle back, select whatever gear I want to use & throttle back up - no grinding, no noises from throw out bearing, shifting is smooth while plowing/blowing. This kind of indicates to me that there might be an issue with the clutch fork/internal linkage rather than the clutch disk/pressure plate? Anyone have any ideas?
