Hi Larry, My name is***** will be glad to help Check the oil condition for discoloration or burnt smell as well as for signs of metal/debris indicating an internal problem. Check the suction screen/filter for signs of metal/debris as well. If ok I recommend checking your pressures for a possible failed clutch pack for reverse. If the pressure drops off in reverse but is in specs in forward it confirms excessive internal leakage and the tractor needs to be split for repair. Let me know
