Allis Chalmers H3 Tractor Parts

About the Allis-Chalmers H3

The H3 was Allis-Chalmers' gas agricultural crawler, introduced in 1960 for work where tracks were more useful than wheels. It was based on the D15 farm tractor and used a four-cylinder gasoline engine, crawler steering clutches, and an eight-speed power-shift transmission.

Built in Springfield, Illinois, through 1967, the H3 was offered alongside the diesel HD3. Its tracks and optional blade, loader, or backhoe made it suited to field, grading, and utility work.

Serial Number Reference

Serial number locations: The tractor serial number is stamped into the left side of the torque tube or clutch housing where it meets the engine.
