Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, and thank you for choosing Just Answer. My name is***** will be happy to assist you. Did our problem occur suddenly, or gradually, over time? How old is your mower?
With your engine off, rock your mower back and forth, as you are attempting to shift your lever.
Thanks for this information. Are you saying that the mower will drive in 1st gear? If your wheels turn in opposite directions when off the ground, this is normal. Is this a six speed transmission? These are only troubleshooting questions.
Remove the shift lever from your transmission, then use a wrench to turn your shift shaft. This will confirm whether or not your shifting linkages are binding. If you still cannot shift out of 1st, even when using your wrench, we may have an internal issue.
Thank you for checking. There is a very good possibility that there is some rust on the shifting components inside your transmission case, that is preventing movement of your shift shaft.
Many times this is cause by moisture being present inside your transmission cases.
Usually you will find rust on your internal shift collar, and internal brake shaft. Sometimes your shifting shaft will seize inside your upper transmission case.
Sounds good. I will look forward to knowing your results ...
