John Deere LA105 starter engages starts to turn flywheel then stops, Rotate the engine backwards 180 degrees the engine starts

SOURCE: John Deere L120 transmission high pitch noise and no forward move

Try jacking the unit up. Start it up and try moving pushing the forward and reverse back and forth and see if it does it then. It sounds like an oil way in the hydrostatic unit has a check valve stuck. Of course make sure that the fluid lever is up. Hope this will help you. donnyb60

You must be in the seat to run the mower ... safety interlocks ... operator presence control is what it is called.

Andy, Hi, well I would start at the Starter myself, usually the thing called the "Bendix" spring jams up and stops it dead. Pull of the Starter, and power it up, off the unit. This will show you if it snaps in and out.
Sometimes a few judicious whacks with a soft hammer will sometimes free up the spring, if thats is indeed what's wrong. Anyway try that first. before any disassembly.
Make sure the Motor CAN actually be turned, by turning the flywheel, this should show you if the Motor is "Free" enough to move.
Also check ALL electrical connection to the starter. Use a meter and see if you are actually getting a voltage to the starter too. make sure your starter battery is good too.
