farmall 300 TA problem

I have a farmall 300 what i was wanting to know is . When i'm going to stop push in on the clutch when in gear on the high side of the TA the tractor will not roll with
clutch pushed in but it will roll on the low side with clutch pushed in . Do i need a TA ajustment other than that TA works fine when driving. Also i have a little gear
oil that leaks from the 2 holes on the TA housing i'm using hy -tran in the trans. Thanks
 
The TA linkage needs adjusted anytime tractor shifts hard with the TA lever ahead. There's a clevis link between the clutch release and TA release that needs reset. It's job is to release the TA whenever the clutch pedal is down, same as with the TA lever pulled back.
 
The actions in the system are as follows:
With the tractor moving (lets say 2nd gear in direct, TA lever forward) as you step on the clutch pedal the freeplay is first taken up by about 1.25 to 1.5 inches of easy movement. At that point the main clutch throwout bearing starts to push the main clutch fingers.
As the pedal is pushed farther, the main clutch disengages (about 2.5" or so).
At that point the tractor stops.
As the pedal is pushed farther, the TA clutch Throwout bearing is pushed against the TA clutch fingers. The TA rod and linkage have been moving in a slotted link, and it has reached its limit.
Now as more pedal travel is used (maybe 4 ") the TA clutch becomes fully disengaged. THis releases the forces on the TA sprague clutch, and the tractor can roll backwards.
The TA clutch should release with at least 1.5" of travel left on the pedal. The TA clutch should be adjusted to the above ideas.
The main thing to remember is to make sure the engine clutch releases first stopping the tractor, then with an inch more down on the pedal, the TA clutch releases. Jim
