Small Engine Troubleshooting Problems? Ask a Mechanic Now.
check that the relief valve is in proper position. Check that the drive belt did not get off an idler pulley or drive pulley? Any driving issues before you done the above mentioned work?
nvm, I was thinking you had hydrostat transmission. All belts on all pulleys still. I am not sure why it would not drive now, if nothing was done to drive system, is why I ask these questions
have you removed the rear wheels for anything also when doing other work
the wheel has a keyway that may have come loose or fallen out. if it is not in place, wheels will not go. can you push machine? can u push in gear?
raise back of machine up and turn wheel(s). do both wheels turn?
okay, so keyways are in and working. Can you see the gear shift arm on transmission move when you move the gear shifter?
