Introduction

J.I. Case 4690 Four-Wheel Drive Tractor

The Case 4690 is a heavy-duty four-wheel drive tractor produced by J.I. Case in Racine, Wisconsin, between 1979 and 1983. Designed for demanding agricultural operations, this machine belongs to a series of high-power tractors focused on traction and field efficiency.

Engine and Performance

The tractor is powered by a 504 cubic-inch (8.3 L) 6-cylinder turbocharged and intercooled diesel engine. It produces 261 horsepower (194.6 kW) at a rated speed of 2200 RPM. This liquid-cooled power plant is designed to sustain high loads during field work, utilizing a compression ratio of 15.8:1.

Transmission and Drivetrain

The transmission system features a three-speed powershift mechanism with four gears in three ranges, providing a total of 12 forward and 4 reverse speeds. Power is delivered to all four wheels through a 4x4 drivetrain, supported by hydraulic wet disc clutches and hydraulic four-wheel steering to enhance maneuverability despite the tractor's size.

Hydraulics and Hitch

The Case 4690 utilizes a closed-center hydraulic system with a pump flow capacity of 31 gpm (117.3 lpm). The rear hitch is a Category III type, capable of lifting 12,750 lbs (5,783 kg) at 24 inches behind the lift point. An independent rear PTO operating at 1000 RPM is included as standard.

Operator Environment and Dimensions

The operator is housed in the 'Silent Guardian' cab, which includes air-conditioning as standard equipment to improve comfort during long working hours. The tractor has a wheelbase of 102 inches (259 cm) and an operating weight of 22,310 lbs (10,119 kg), which can be increased to 25,230 lbs (11,444 kg) when ballasted.
