New to the site. Lots of great info! I have a Ford 120 with 4 speed trans. I am having trouble getting the tractor to shift into gear. When tractor is in gear pressing the brake/clutch stops the tractor and belt slips on input pulley, but as soon as I take it out of gear with brake/clutch still pressed the drive pulley starts to spin. When in neutral, the brake shaft and input pulley are not connected, as in the brake/clutch has no affect on the input pulley causing grinding of gears when shifting from neutral. Any help would be appreciated. Hopefully I have not made this too confusing.
