Hi, I have similar issue with my ZT20/50, the right side has less pulling power than the left side; getting worse when warm. Last time used it on an overgrown quite steep garden and may have overheated it a bit. When loaded onto the trailer realized that the hydraulic system started to leak, quite a bit of oil ran out. Brought to the service but they can't find an obvious leak. The main pressure hoses are dry. There were drops at the return line where it is connected to the tank. The oil was very dark (was time to change it anywhere).
Had anybody a similar issue? My mower has now 250 hours; no other issue other than the difference in pulling power.
