2. Worn out ball bearing

There is a ball bearing that houses the transmission case that holds the shift detent fork. If your mower isn’t moving forward, check if it is worn out. A worn-out ball bearing will not hold it in forward.

Fix: Replace the worn-out ball bearing with a new one.

3. Broken or worn-out shifting gears or keys

If the shifting gears or keys are broken then the forward gears will not work well. This will result in bad transmission which might affect the mower’s ability to move forward.

Fix: Replace broken or worn-out shifting gears or keys with a new one.

4. Rusty Controls

Rusty controls may keep your riding lawn mower from moving forward. The effect of rusty controls might cause the mower to only go on the reverse and not forward.

Fix: For optimal mower performance, simply change the rusty controls of your riding mower to new ones

5. Worn or Bent Shift Fork

This can also cause this problem while mowing with your machine. If this happens, ensure that you check the shift fork to see if it is worn or bent. 

A worn or bent shift fork will prevent it from engaging the edges on the shifter clutch of your riding mower.

Fix: If you can repair the bent shift fork, shim the side gear in to get full engagement.
