Introduction
International Harvester 4100 Agricultural Tractor
The International Harvester 4100 is a four-wheel-drive agricultural tractor produced between 1965 and 1968 in Rock Island, Illinois, USA. With a total of 1,217 units manufactured, this machine was designed to provide significant tractive force for heavy-duty field operations.
Engine and Performance
The tractor is powered by an International Harvester 6-cylinder, liquid-cooled, turbocharged diesel engine. It features a displacement of 429 cubic inches (7.0 liters) and a compression ratio of 16:1, delivering a rated power output of 144 horsepower. The induction system utilizes a dual-stage dry air cleaner to maintain engine efficiency under field conditions.
Transmission and Drive
The 4100 utilizes a 4x4 all-wheel-drive configuration to maximize traction. The drivetrain includes a sliding gear transmission providing 8 forward and 4 reverse speeds, controlled by a dry disc clutch. This gear range allows the operator to select appropriate speeds for various heavy-duty agricultural implements.
Hydraulics and Power Take-Off
The hydraulic system is equipped with a pump providing a flow rate of 16.5 gpm (62.5 lpm). The tractor features an optional independent rear power take-off (PTO), available in 1000 rpm configurations with either 1-3/8 or 1-3/4 inch shaft diameters. A Type III rear hitch is also available as an option for implement attachment.
Chassis and Handling
To manage its substantial mass, the tractor employs hydraulic power steering and integral hydraulic expanding shoe brakes. The unit rests on a 100-inch wheelbase and is fitted with 18.4-30 agricultural tires on both the front and rear axles. The operating weight is 15,175 lbs (6,883 kg), which can be increased to 19,100 lbs (8,663 kg) when ballasted.
