Introduction
J.I. Case 803-B High-Clearance Tractor
The J.I. Case 803-B is a specialized high-clearance tractor produced between 1958 and 1959. Manufactured in Racine, Wisconsin, USA, this machine was designed to meet specific agricultural requirements, with a limited production run of 30 units.
Engine and Performance
The tractor is powered by a 4-cylinder, liquid-cooled diesel engine with a displacement of 267 cubic inches (4.4 L). It operates at a rated speed of 1800 RPM and features a compression ratio of 15:1. The engine utilizes an oil bath air cleaner and an electric starter system to ensure reliable operation in field conditions.
Transmission and Drivetrain
The 803-B is equipped with the Case-O-Matic transmission system, which integrates a torque converter with a bypass feature to allow for direct drive locking. The transmission provides eight forward and two reverse gears, managed by a single shift lever. Power is transferred through a hydraulic wet disc clutch, facilitating smooth engagement during operation.
Operational Controls and Mechanical Features
This two-wheel-drive model is designed for maneuverability, featuring power steering to reduce operator fatigue. Braking is handled by mechanical disc brakes, providing consistent stopping power. The rear power take-off (PTO) operates at a standard speed of 540 RPM, allowing the tractor to drive a variety of agricultural implements.
