Hi all first post here. I have a 2019 L3901 and yesterday the HST pedal stopped working, tractor won't go forward and wants to creep backwards when the brake is off. Was working flawlessly up to this point. I've checked my shifters and 4wd, all correctly positioned. Fluid is half full. Pedal will not depress to fwd position and will travel to reverse position. can't figure out what may cause this issue. Any ideas on what to look at?

Look at what the pedal moves under the pedal area. Probably the linkage is loose or something is jamming it.

(different tractor) This happened to me and major panic set in. (thing had like 10hrs on it)

What had happened was the knob that holds the screen by your knees on had backed itself out, fell to the floor and jammed in the slot where the HST pedal rides.

Removed blockage, reinstall (tighter). Heart rate returned to normal.

Whew.

Check the linkage, it is on the LH side of the transmission case, under the floor. A lot of times a stick or rock will get wedged into the linkage.
