A Hustler mower, as with any riding lawn mower, must be properly maintained to work properly. Starting and running a Hustler mover requires adherence to certain procedures that can be found in the owner's manual.
Manually inspect the blades and blade spindle for packed dirt and grass clippings. A build up of debris, dry or wet can restrict the movement of the blades.
The blade spindle bolt should be tightened after the first two hours of operation and every 100 hours after that. This spindle should be tightened to a specified torque value and should be done by a professional. The owner's manual should provide a torque value chart.
A bent or otherwise damaged blade may keep the blade from engaging properly. Inspect blades for damage prior to mowing and after hitting a rock or other objects.
As a power saving feature, the blade engagement ability will time out if the machine sits idle for too long. In this case, the digital display codes should read "02A54."
