Sounds more like a transmission that needs oil, than a purging problem. Purging you just raise the wheels and slowly work unit forward and reverse , until the wheels start to move. I would try adding some oil to the unit. 15W50 engine oil, and you may have to find the vent on top of the transmission and remove to add. Only add about a cup of oil. Then try it.
