How to fix ?

If you believe this to be the case, you can simply put fresh fuel in the tank and, after a few tries, the mower should start up as normal. However, if the mower has sat idle for three to six months, it has likely gone bad and will either need to be replaced or you can try adding a fuel stabilizer. To solve this issue, you should connect the hydraulic motor to a 300 Series SCV with a compensator valve to control pressure variation. You should also consider adjusting oil flow through the Selective Control Valve either at or below the maximum oil capacity of the motor.
