Introduction
John Deere 1120 Utility Tractor
The John Deere 1120 is a utility tractor produced between 1967 and 1975 at the company's facility in Mannheim, Germany. Designed for general agricultural applications, this model features a 2.7-liter three-cylinder diesel engine and was offered in a two-wheel-drive configuration.
Engine and Performance
The tractor is powered by a 3-cylinder, liquid-cooled John Deere diesel engine with a displacement of 164.5 cubic inches (2.7 liters). It utilizes a direct injection fuel system and provides a net power output of 51 hp (38.0 kW), with a gross power rating of 53 hp (39.5 kW). The engine operates at a rated speed of 2500 RPM, with a peak torque of 123 lb-ft delivered at 1350 RPM.
Transmission and Drivetrain
Two transmission configurations were available: a partially synchronized unit providing 8 forward and 4 reverse gears, and a two-speed power shift transmission offering 16 forward and 8 reverse speeds. The drivetrain includes a dry disc clutch, planetary final drives, and a mechanical rear differential lock to assist with traction in field conditions.
Hydraulics and PTO
The hydraulic system is of the closed-center type, delivering a pump flow of 12.9 gpm (48.8 lpm) at a pressure of 2250 psi. The rear hitch, categorized as Type II/I, provides a lift capacity of 3570 lbs (1619 kg) and features both position and draft control. Power Take-Off (PTO) options include a live rear PTO with 540/1000 RPM speeds and an optional independent front PTO.
Dimensions and Operator Station
The 1120 is built on a 80.7-inch wheelbase with an overall length of 135 inches. The operator station is an open-platform design, with a two-post fixed ROPS available as an option. Braking is handled by hydraulic wet disc brakes, ensuring consistent stopping power.
Conclusion
The John Deere 1120 is a robust utility tractor suited for varied farming operations, characterized by its German engineering and flexible transmission options. Its hydraulic lift capacity and dual-speed PTO capabilities make it a versatile machine for handling standard agricultural implements from the late 1960s and 1970s.
