Introduction
John Deere 4400 Compact Utility Tractor
The John Deere 4400 is a compact utility tractor produced between 1998 and 2001 at the John Deere facility in Augusta, Georgia, USA. This machine was designed to serve as a versatile platform for various agricultural, landscaping, and property maintenance tasks.
Engine and Performance
The tractor is powered by a liquid-cooled engine with a displacement of 1.6 liters (100.2 cubic inches). It utilizes a direct injection fuel system, delivering a gross power output of 35.7 hp (26.6 kW). The engine operates within a range of 950 to 2700 RPM, supported by a 12-volt starting system and an air heater for cold-start assistance.
Transmission and Drivetrain
Two transmission options were offered: a 12-speed partially synchronized SyncReverser gearbox with a left-hand reverser, and a 3-range infinite-speed hydrostatic transmission. Both systems utilize a mechanical wet disc clutch. The tractor features four-wheel drive as standard, complemented by a mechanical rear differential lock and differential wet disc brakes for improved traction and control.
Hydraulics and PTO
The hydraulic system is of the open-center type, providing a total flow of 13.3 gpm (50.3 lpm), with 8.3 gpm allocated to the pump flow and 5 gpm to steering. The rear hitch is a category I type with position control, capable of lifting 2200 lbs (997 kg) at 24 inches behind the lift point. The independent rear PTO operates at 540 RPM at an engine speed of 2700 RPM, with an optional mid-mount PTO available.
Conclusion
The John Deere 4400 is a robust compact utility tractor suited for operators requiring a balance of maneuverability and implement versatility. Its combination of four-wheel drive, multiple transmission configurations, and significant hydraulic capacity makes it a reliable choice for small-to-medium scale agricultural and utility operations.
