Key features of the engine are:

  • Economical cast-in-block cylinder design for good cooling and long life
  • Direct fuel injection
    • Improves starting
    • Injects fuel directly on top of pistons for more efficient combustion
    • Develops more horsepower per gallon of fuel than indirect injection engines
  • Aluminum alloy pistons with built-in steel struts are lightweight to reduce connecting rod bearing loads and provide good heat transfer characteristics
    • Design permits tighter tolerances and neutralizes expansion of the piston, which reduces blow-by and noise from piston slap
    • Top rings are higher on the piston and a thinner head gasket is used to greatly reduce the volume of unburned waste gases and increase combustion efficiency
  • Timing gears and injector drive gears have a helical profile to reduce engine noise
  • Auto-bleed fuel system
    • There is no need to prime the system if the tractor runs out of fuel
    • The system will self-prime the injection pump, lines and injectors, providing fast fuel recovery for easier starting
  • High-capacity lubrication system provides filtered oil, under pressure, to all engine bearings for long life 
  • Key start and shutoff eliminates fuel shutoff knob
    • Electric solenoid shuts fuel supply off immediately when key is turned off, which replaces the need to pull a fuel shutoff lever like many older tractors
  • Fuel filter with replaceable element
  • Water separator
    • See-through coolant recovery tank permits operator to check coolant level without removing radiator cap
Dry-type air cleaner

  • Dry-type air cleaner with safety element  
    • Dual element design for added engine protection
    • Easy to service
  • Hood can be easily opened without tools for full access to the engine
  • Horizontal exhaust
    • Discharges fumes away from the operator and reduces noise from engine
    • Improves operator visibility
