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 1800s, 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
