  1. Tractor Safety, Operation, and Maintenance Tractor Systems A VGP Production 2003

  2. Tractor Systems The tractor has many systems that must be properly serviced and maintained to insure long life and service.

  3. Engine Classifications With the demise of the steam powered tractor in the late 1800’s, most modern tractors are equipped with internal combustion engines. Internal combustion engines are identified by the number of strokes in the cycle and by the fuel that is used to run them. Common Tractor Classifications: 4 stroke cycle - gasoline - diesel - LP

  4. Engine Internal Components

  5. Four Stroke Cycle

  6. Major Systems • Intake • Exhaust • Lubricating • Electrical • Cooling • Fuel • Hydraulic • Drive Train

  7. Intake System • Parts: • Pre-Cleaner • Air Cleaner • Intake Manifold • Intake Valve • Turbocharger (if used) • Intercooler (if used)

  8. Exhaust System • Parts: • Exhaust Valve • Exhaust Manifold • Muffler • Cap

  9. Lubricating SystemFull Flow & By-Pass • Parts: • Crankcase Oil Reservoir (Oil Pan) • Oil Pump • Oil Filter • Oil Passages • Pressure Regulating Valve • Oil goes to: • Camshaft Bearings • Crankshaft Main Bearings • Piston Pin Bearing • Valve Tappet Shaft
