Question
I have a Craftsman Model 247.28980. I originally had a carburetor solenoid problem. I replaced that. I pulled the tractor up on ramps to get it up higher to replace the solenoid, it went fine. When I took it off the ramps and cranked it, engine ran fine. Now the hydrostatic transmission just whines and wont move the tractor. I set the brake when I pulled it up on the ramps and released it when I took it off. It's like the brake didn't release! I took off the rear right wheel and it looks like everything is connected properly, but not knowing how it is supposed to look I am not sure. I have pressed the brake several times very hard in an attempt to get it to release, but with no success. Any ideas?

Answer
Your hydrostatic transaxle is an MTD part number 918-0319.

Is the by-pass rod dis-engaged?

The URL below is describes some common problems associated with your transaxle:

Your transaxle should be a Hydro-gear unit.  Here is the hydro-gear service manual URL:

I would start with the easy items, by-pass rod, brake adjustment and then proceed to the more challenging services.  Make sure the brake is not causing the problem.

Experience

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.
