Small Engines (Lawn Mowers, etc.)/JD LT133 transmission problem


When I put the manual trams into gear it dies . It's like it locked up. When neutral  I can push it , when in gear I can't push it , like has locked up . When I elevate the tractor wheel s turn fine in gear . I tried to start it with wheels elevated , but can't figure out how to by pass seat sensor. Any thoughts on what is wrong.

In gear you should not be able to roll the mower.

Look under the mower at the transmission and let me know what model you have.  This link will help you locate transaxle model number.

Let me know the transaxle model so I can provide some tips.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
