John Deere 4066M Heavy Duty Compact Utility Tractor

Increased versatility with Category 1 and 2 implement compatibility

The 3-point hitch has plenty of lift capacity to handle heavy implements.

Category 1 and Category 2 hitches allow for hookup of a variety of 3-point hitch implements.

• Right-hand lift link and center-link are adjustable to save time when leveling equipment.

3-point hitch control

The 3-point hitch control on the 4M Heavy-Duty Series Tractors is called position control.

Rate-of-drop/stop valve

Rate-of-drop/stop valve regulates lowering speed of 3-point hitch. It can be shut off completely to stop hitch movement.

Telescoping draft links (extendable draft links)

Telescoping draft links will reduce the amount of effort to attach 3-point hitch implements by allowing the operator to make small adjustments without moving the tractor. It is standard on 4M Heavy-Duty Tractors.

Horizontal sway bar stabilizers regulate side-to-side sway of 3-point-hitch-mounted equipment.

• 4M Heavy-Duty Tractors come equipped with the horizontal stabilizer bars, the lock pin goes into the stabilizer bar vertically
• Mounted on outside of lower links for fast, easy equipment hookup
• Top-pull pin design allows easy adjustment without use of tools
• Retainer cable holds pin while pin is removed to adjust stabilizers

Rockshaft position control lever allows operator to accurately set implement depth or height.

• Operates precisely with no jerking or leak down
• Control lever features easy-to-read increments for accurate positioning

Easy-to-adjust depth stop enables the operator to lower implement to a predetermined depth.

Excellent visibility provided by standard lighting equipment

Standard equipment lighting includes:

• Wraparound-style wide-angle halogen headlights for better lighting and visibility
  • Premium integrated automotive-style headlight bezels
• Two amber flashing warning lights
• Warning lamps placed to meet ASAE S279.10 standards
• Dual lamps with increased separation for better visibility and distinction at a distance
• Two fender-mounted forward and rear halogen working lights

Maximize productivity with an eHydro™ transmission

The tractor is available with a three-range electronic hydrostatic (eHydro) transmission.

• Fluid under pressure transmits engine power to the drive wheels using a pump and motor
• Functions both as a clutch and transmission
• Provides high torque for startup
• Reduces powertrain shock loads

Danfoss® supplies both the pump and motor. This ensures that the components are matched to each other, providing maximum efficiency.

Danfoss eHydro transmission is used for reliable operation. Durability features include:

• Large forged trunnion shaft with larger support bearings that reduce vibration and noise

• Center section made from ductile iron (much stronger than grey iron used in many competitive transmissions)

• Transmission oil cooler cools transmission oil for longer transmission life

Safety features of the eHydro transmission include:

• The tractor will start with one or both foot pedals depressed, but it will not move until both pedals first return to neutral.

• Operator presence system means the tractor will come to a stop if the operator leaves the seat but will not shut off unless the power take-off (PTO) is also running.

Key John Deere advantage

John Deere's Twin Touch foot controls offer key advantages over competitive hydro model tractors.

• Some competitive hydrostatic tractors use a treadle pedal designed (toe-heel) foot control for operation of the hydro.
  • Requires the operator to use both toe and heel to change direction, resulting in increased operator fatigue

Integrated eHydro features

The eHydro convenience controls have been integrated into a single module. Combining features such as SpeedMatch™ LoadMatch™, MotionMatch, eThrottle, and automotive-style cruise control pulls the maximum efficiency out of the eHydro transmission tractors. All these features are standard on the 4M Heavy Duty and 4R models and deliver customers an easier and more comfortable experience.

• Infinitely variable ground speeds, in each range, allow the operator to match the speed of the tractor to the job.
• No clutching for fast and easy direction changes
• Twin Touch foot pedals for quick and easy forward/reverse operation
• Cruise control is optional equipment
  • Cruise control switch is located on the right-hand console for easy access
  • Cruise control is electronically engaged and disengaged, which allows for precise setting of speed

Increase productivity with integrated mid-mount loader selective control valve (SCV) and single rear SCV

The tractor is base equipped with a dual mid SCV.

• Two sets of right-hand side-mounted couplers allow operating four hydraulic functions (such as raising/lowering boom and curling/dumping bucket).
• Large 12.7-mm (0.5-in.) diameter couplers are used for maximum oil flow to implements.
• Hydraulic valves have excellent featherability for smooth operation of equipment.
• Couplers are color coded for correct hookup.
• Hydraulic regenerative (REGEN) active, in dump position, out of neutral:
  • Provides faster dump cycle
  • Prevents cylinder voiding

Rear hydraulic couplers - SCVs

The tractor is also base equipped with a single third electrohydraulic SCV.

• One set of rear mounted couplers allow operating rear mounted hydraulic implements.
• Large 12.7-mm (0.5-in.) diameter couplers are used for maximum oil flow to implements.
• Hydraulic valves have excellent featherability for smooth operation of equipment.

Optional rear hydraulic couplers - SCVs

• Power beyond

Power beyond kit

Optional on the 4M Heavy-Duty Series Tractors, the power beyond kit:

• Contains rear-mounted couplers and hoses to access pressurized oil at the rear of the tractor; the kit will be used for operations such as backhoe or log splitters.
• Couplers are a 12.7-mm (0.5-in.) diameter for maximum oil flow to implements.
