I am working on a customers skid steer stuck in a field, caterpillar 236d3 with 885hrs. Everything turns on and parking brake unlocks but the drivers rear wheel does not turn and acts locked up. It rolls maybe an inch in either direction but then stops. The front drivers side turn forward and reverse just fine and the passenger side works correctly. Being there is two drive motors and both seems to be unlocking i am assuming i have an issue at the rear wheel on drivers side? I dont understand how the front tire can move freely but rear cant if connected by chain.
Seized wheel bearing.? Post a Serial Number for a parts breakdown.

pulled the wheels and side cover. only had a little oil to drain out and chocolate milky. seems it just broke the link and wound up around rear wheel. got a new chain and oil in route.
