Does reverse work? Have you checked the drive belt?

reverse works well I've checked all belts and linkages oil levels washed and cleaned up just wounding if it could be something in the hydraulic transmission
Expert:  Curtis B. replied 1 year ago.

Hydrostat transmission should work equally in forward and reverse. You just reroute the oil flow to change direction. Have you raised it up in jack stands and ran it to see if there is something obvious knocking?
