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
- •The 4066R represents the top-performing open-station or cab-equipped compact tractor in John Deere's lineup for most buyers — 65 HP, eHydro with LoadMatch, and cab availability is a hard combination to beat in this class
- •54.2 PTO HP is genuinely utility-class — runs 7-ft rotary cutters and larger implements without the tractor feeling stressed
- •Optional cab is the same refined unit as the 4052R and 4075R — very comfortable for all-day operation
- •EHydro LoadMatch prevents stalls during aggressive loader work, which matters at 65 HP where loads are heavier
- •Hitch Assist makes solo 3-point connections standard and easy
- •At $57,500–$71,500, the 4066R cab-equipped competes directly with the bottom end of the utility market — buyers should compare it against the 5045E for similar money
- •Strong resale value
- •Built in Augusta, Georgia
