300u hard to shift gears

My 300u is hard to shift gears, as if I was trying to do it without pushing in the clutch... the other day I backed up a hill, and had a heck of a time shifting it out of reverse.

any suggestions?

thank you
 
The TA is out of adjustment. The one way sprag clutch in the TA will not turn backwards and it is linked to the TA spinning gear set by that one way
clutch. when the friction clutch in the TA is out of adjustment it doesn't release and puts the transmission in a bind.

TA adjust: The process (as I do it): Set the clutch free play at 1 inch down from all the way up measured at the foot plate to cast contact in the
pedal arm. this can be felt by hand. In an open area with nothing to run into, use low gear, and measure the point that letting up on the pedal causes
the tractor to begin to move. this is the engagement point of the master clutch. The TA linkage is now adjusted so it begins to be released at this
position of the foot pedal. further depressing the pedal releases the TA clutch fully. (usually another 3/4" or so to an inch of foot travel. This
assures that the TA clutch is fully engaged when the master clutch applies power through it. It also assures that the full pedal depression releases
the TA clutch so shifting is not bound up. The lever should apply and fully release the TA clutch very near the center of its travel. Doing this
compensates for linkage wear and I have had no issues doing it this way. Jim

Wow... thanks
 
This method assists with worn linkage as well. the lever must pull the TA front clutch out of contact about mid travel. adjust it if needed after
getting the pedal corrected. Jim
