I did this project a couple months ago, just as an experiment and for fun. I'm actually quite happy with the way it turned out. The pedal assembly itself is off of a cheap Poulan hydrostatic riding mower.
The pedal is mounted on a round rotating shaft that goes through the frame and out the other side for stability. The movement was super jerky and fast so I used the original damper shock that came out of the hand control linkage on the other side of the frame to smooth out the motion.
Underneath I welded a piece onto the shaft pointing downward… it’s all up inside the frame though so it doesn’t get in the way of the mower deck. (My diff lock linkage does that…) I also welded the original turnbuckle into the linkage so the neutral position could be adjusted. You can see the pedal shaft underneath in the last picture. You can also see the nice oil leak. There are also two springs that counteract each other so the pedal returns to neutral/stop. I’m pretty happy with the way it turned out for just playing around.
If I did it again on another tractor, I might try using a heavy duty flexible cable (like maybe a brake cable from a golf cart) just to make it easier. Any suggestions or improvements are definitely welcome!
