1. Ensure the park brake switch is applied (set to ON).
2. Walk around the tractor and inspect it for damage or missing equipment.
3. Check for damaged or under-inflated tires. Check that cold tire pressure is 130 psi
(896.3 kPa). Look for cuts and cracks in the tire’s sidewalls and for foreign objects in the
tread.
4. Check the front/rear axle differential cases and planetary hubs for oil leaks.
5. Check for proper operation of the hitches.
