The John Deere 1850 is a utility tractor produced by John Deere in Mannheim, Germany, between 1986 and 1994. As part of the 1750-1950 series, this machine was engineered to provide reliable mechanical performance for general agricultural applications.
Engine and Performance
The tractor is powered by a 2.9-liter, 3-cylinder liquid-cooled diesel engine. It delivers a net power output of 55 hp (41.0 kW) at a rated speed of 2400 RPM. The engine produces a maximum torque of 143.8 lb-ft (195.0 Nm) at 1300 RPM, providing consistent lugging ability for field operations.
Transmission and Drivetrain
Multiple transmission configurations were offered to suit specific operational requirements, including a standard 8-speed synchromesh, a 16-speed Power Synchron transmission with a two-speed power shift, and a 12-speed creeper transmission. The drivetrain features a hydraulic wet disc clutch, planetary final drives, and power steering, with options for either two-wheel or four-wheel drive.
Hydraulics and PTO
The hydraulic system utilizes a closed-center constant pressure design, delivering a pump flow of 11.6 gpm (43.9 lpm) at a system pressure of 2756 psi (190.0 bar). The rear independent PTO operates at 540 RPM, with an optional 540/1000 RPM configuration available. The Category II/I rear hitch offers both position and draft control, with a lift capacity of 2810 lbs (1274 kg) measured at 24 inches behind the lift point.
Operator Station and Dimensions
The operator station was available with a standard ROPS, with optional MC1 or CC2 cab configurations introduced after 1990 to improve operator comfort.
