Powerful John Deere engine

Power is provided by a durable and efficient high-torque 3-cylinder Yanmar TNV Series diesel engine.

 
This series of engines was developed to meet environmental requirements for Tier 4 (2025R) emission requirements by featuring lower levels of both exhaust and emissions.

* As per 97/68/EC ISO at rated speed.

Yanmar TNV Series engine offers these features:

• Economical cast-in block cylinder design for good cooling and long life
• Indirect fuel injection on the 2025R uses a pre-combustion chamber to give the engine a smooth and quiet operation
• Direct fuel injection on the 2032R injects fuel on top of the pistons and allows for more efficient combustion and fuel economy
• 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 generating 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 roll-off profile giving almost no clash, no noise, and no backlash
• Special flywheel flange seals flywheel air turbulence noise inside the flywheel housing
• 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 on the 2025R provide quick starts in temperatures down to 0° F. (Optional engine coolant heater attachment will assist starting under more extreme conditions.)
• Air intake heater cold starting aid on the 2032R provides quick starts in temperatures down to
  0° F. (Optional engine coolant heater attachment will assist starting under more extreme conditions.)
• Auto-bleeding 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

• Dry-type air cleaner (1) with safety element (2) 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
• Air cleaner service indicator is standard equipment on all models and alerts owner as to when to service the air filter
• The one-piece hood can be easily raised for full access to engine compartment
• Front grille screen and sides on one-piece hood provide excellent flow of air to the engine compartment
• Sealed radiator compartment keeps trash and debris on outside of hood
• Improved fuel fill is relocated to right side of hood allows easier refueling
• Horizontal exhaust discharges fumes away from the operator station, reducing noise and improving operator visibility and comfort.
