Hello,

The first thing to check is the all the steering pivot and cylinder joints. Verify they are free and have been greased. If they are seized, the machine will not turn.

Next test the pressure of the pump. If you have a push blade, this uses the same pump. If the blade is working correctly, the pump is ok.

Next step would be to check the relief and priority valve. Remove it and inspect it for sticking valves or debris plugging orifices.
