Yanmar TNM Series engine offers these features:
 
  • Economical for good cooling and long life
  • Isolated engine provides reduced vibration and noise for the operator; indirect fuel injection uses a pre-combustion chamber to give the engine a smooth and quiet operation; aluminum alloy piston with built-in steel struts are lightweight to reduce connection rod bearing loads and provide good heat transfer characteristics
    • Design permits tighter tolerances and neutralizes expansion of the piston, thereby reducing blow-by gas and less noise from the piston slap
    • Higher top rings on the piston and a thinner head gasket greatly reduces the volume of unburned waste gases and increases combustion efficiency
  • Timing gear teeth have a designed roll-off profile giving almost no clash, no noise, and no backlash
  • High-torque reserve provides plenty of power under heavy load, yet retains excellent fuel economy
  • Fuel filter with replaceable element
  • Full-pressure lubrication system provides filtered oil under pressure to all vital engine parts
  • Glow plugs provide quick starts in temperatures down to 0 degree F. (Optional engine coolant heater attachment will assist starting under more extreme conditions.)
  • Auto-bleed fuel system means there is no special bleeding required if the tractor runs out of fuel; this system will self-prime the injection pump, lines, and injectors, providing fast fuel recovery
  • Key start and shutoff eliminates fuel shutoff knob
  • Electric solenoid shuts fuel supply off immediately when key is turned off
  • See-through coolant recovery tank permits operator to check coolant level without removing radiator cap
  • Dry-type air cleaner with safety element keeps dirt and other contaminants out of the engine
    • Safety element (second filter) will protect engine if primary filter would develop a leak
    • Protects engine when servicing primary filter
  • Side screen panels and front grille screen provide excellent flow of air to the engine compartment
  • Sealed radiator compartment keeps trash and debris on outside of hood
  • Single-piece side panels can be removed for easy and quick access to the engine
  • Horizontal exhaust discharges fumes away from the operator station, reducing noise and improving operator visibility and comfort
