John Deere 2025R Compact Tractor

Yanmar® diesel engine

Power is provided by a durable and efficient high-torque 3-cylinder Yanmar® TNV Series diesel engine. This series of engine was developed to meet environmental requirements for Tier 4 emission requirements by featuring lower levels of both exhaust and emissions.

• Economical cast-in-block cylinder design for good cooling and long life.
• Indirect fuel injection on the 2025R uses a pre-combustion chambers 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 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 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 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.
• 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 for easier refueling.
• Horizontal exhaust discharges fumes away from the operator station, reducing noise and improving operator visibility and comfort.

Hydrostatic transmission

The 2025R and 2032R hydrostatic (HST) tractors feature a foot-controlled hydrostatic transmission.

• Low pedal effort makes the transmission very easy to operate.
• Fluid under pressure transmits engine power to the drive wheels through a hydraulic pump and motor.
• The hydrostatic drive unit functions both as a clutch and transmission.

Twin Touch™ foot controls allow selecting both speed and direction of travel with a touch of the toe. Ideally suited for jobs where productivity is a must, such as loader or mower applications.

• Infinite ground speeds, even at full throttle, to match the job.
• No clutching for fast direction changes.
• Faster, easier, and more precise to operate than competitive tractors with treadle pedal design (toe-heel).
• Provides high torque for start up.
• Reduces powertrain shock loads.
• Large rubber foot pedals were designed for operator comfort and allow for convenient operation of the tractor.

Transmission has two speeds – hi and lo range.

• The range lever is located next to the left-hand fender, conveniently within reach of the operator

Kanzaki® HST transmission is used for reliable operation.

• Large forged one-piece trunnion shaft with larger support bearings that reduce vibration and noise.
• Innovative transaxle combines an HST transmission, gear reduction axle, and clutch.
• Pressure side filtration allows using a finer mesh filter (10 micron) than suction filtration systems used on many competitive tractors.
• Charge pump used to deliver oil to transmission (some competitive tractors use one pump for transmission and hydraulics).
• Oil cooler cools transmission oil for longer transmission life.

Open operator station

The operator station has been redesigned for greater operator comfort and visibility.

• Sloping hood design provides improved visibility.
• Plenty of room for comfortable operation.
• High-back seat with suspension.
• Retractable seat belt.
• Molded polymer foot deck design on 2025R dampens sound and vibration.
• Large, easy-to-read automotive style instrument panel.
• Step-through operator station makes getting on and off the tractor easy.
• Fender-mounted handrails, large and easy to grab, assist the operator when getting on and off the tractor.
• Controls are on the fenders for operator convenience.
• Operator controls are color-coded for easier identification.
• Front horizontal exhaust for increased operator visibility.

Operator presence system.

• Enhanced operator presence system on the 2032R allows for simpler out-of-seat power take-off (PTO) operation; however, the engine will shut down if the operator leaves the seat when the transmission or mid-PTO is engaged (see operator’s manual for instructions).
• On the 2025R, if the operator leaves the tractor seat when the transmission, mid-PTO, or rear-PTO is engaged, the engine will shut down.

Full instrumentation is standard equipment for operating convenience and confidence. Updated automotive style instrument panel includes:

• Four-wheel drive (4WD) indicator light.
• Tach/hour meter.
• Electric fuel gauge.
• Oil pressure indicator light.
• Alternator indicator light.
• PTO engagement light.
• Park brake light.
• Flashing warning lights.
• Coolant temperature light.

Updated seat design offers improved back support for more comfortable operation.

• Seat adjusts fore/aft for operator convenience.
• Seat adjustment lever is located on the right-hand side of the seat.
• Seat flips forward for protection from the elements.

Optional iMatch™ Quick-Hitch allows for easy implement hookup

One of the greatest operator concerns involves difficulty in attaching tractor implements. John Deere has addressed this issue with the iMatch™ Quick-Hitch.

The iMatch™ Quick-Hitch provides easy hookup and a guaranteed fit for all Category 1 implements designed to meet the ASAE Category 1 Standard S278.6 for quick-attach hitches.

• All implements require a set of bushings in order for the attachment to fit and work properly with the iMatch™ Quick-Hitch. One set of bushings comes with the iMatch™ Quick-Hitch.
• Upper Bushing
  • Inside Diameter: 0.76 – 0.77 In. (1.93 – 1.96 cm)
  • Outside Diameter: 1.24 – 1.25 In. (3.15 – 3.18 cm)
• Lower Bushings
  • Inside Diameter: 0.88 – 0.89 In. (2.24 – 2.26 cm)
  • Outside Diameter: 1.43 – 1.44 In. (3.63 – 3.66 cm)

Easily change power take-off (PTO) driven implements with iMatch™ AutoHitch™ System

iMatch™ AutoHitch™ is the next generation of the successful iMatch™ Quick-Hitch that allows operators to hook up the PTO shaft of certain PTO-driven implements. This revolutionary system is the first of its kind, allowing the operator to change from a compatible rotary cutter to a compatible rotary tiller without leaving the seat of the tractor.

John Deere continues to lead the way with innovative designs that ensure operators can quickly and easily change implements and attachments on the compact utility tractors with no tools and little experience needed.
