4 Series Compact
The 4 Series represents the top of John Deere's compact tractor line, offering 44-66 HP with utility-class features in a compact footprint. The 4044M is the current entry model, delivering excellent power-to-size ratio for serious property owners and small farmers who need more capability than the 3 Series but don't need a full utility tractor.
44 HP in a Compact Frame
The 4044M packs 44 gross HP into a compact tractor frame, giving you utility-class power with compact-class maneuverability. This makes it ideal for operators who work in tight spaces but need to run heavy implements like 6-foot rotary cutters, large box blades, and round bale spears.
- •44 gross HP Yanmar diesel engine
- •Compact dimensions for maneuvering in tight spaces
- •Heavy-duty frame designed for utility-class implements
- •4WD standard with mechanical front-wheel drive
eHydro with LoadMatch & SpeedMatch
The 4044M's eHydro transmission with LoadMatch automatically senses engine load and adjusts ground speed to prevent stalling. SpeedMatch cruise control maintains consistent speed for mowing and road travel. Together, these features make the tractor nearly effortless to operate.
- •LoadMatch prevents stalling under heavy loads
- •SpeedMatch cruise maintains consistent ground speed
- •3-range hydrostatic for optimal speed selection
- •Twin Touch forward/reverse pedals
Heavy-Duty Loader Integration
The 4044M pairs with John Deere's 400E loader, which delivers significantly more lift capacity than 3 Series loaders. Quick-park mounting lets you remove the loader without tools, and the skid-steer compatible quick-attach bucket accepts a wide range of attachments.
- •400E loader with strong lift capacity
- •Quick-park tool-free loader removal
- •Skid-steer compatible quick-attach interface
- •Self-leveling available for precise material handling
Built for Serious Work
The 4 Series is built heavier than the 3 Series with a stronger frame, larger axles, and more hydraulic capacity. This translates to better stability with heavy implements, more confident slope operation, and a longer service life under demanding conditions.
- •Category 1 and 2 3-point hitch compatibility
- •Independent 540 RPM rear PTO
- •Available factory cab with heat and AC
- •2-year/2,000-hour bumper-to-bumper warranty
What Owners Say
- •65 HP in a compact tractor frame is a lot of power per dollar — the 4066M brings utility-class capability to a compact footprint at the M-series economy price
- •PowrReverser with 12 forward speeds makes direction changes and speed selection efficient for loader and field work
- •54.2 PTO HP handles 7-ft rotary cutters, disc harrows, and most mid-utility implements that typical compact tractors can't run
- •At 3,982 lbs operating weight, the 4066M is heavier and more stable than lighter compacts in this class
- •No cab option on the M-series is the main limitation — if climate-controlled operation matters, the 4066R is the right choice
- •At $51,500–$63,500, this is a premium compact tractor — strong resale and dealer support are the consistent reasons buyers choose John Deere over Kubota or Kioti at this power level
- •Built in Augusta, Georgia
