What should I do if the engine will not start or crank?

Check that the 20A fuse in the tractor's wiring harness has not blown; it is located at the rear of the unit underneath the fender near the battery. Also confirm that the parking brake is engaged and the PTO lever is in the disengaged (OFF) position, as the safety interlock system prevents the engine from cranking unless both conditions are met. Always replace the fuse with one of the same amperage capacity. (Page 17, Page 26)
