Allis-Chalmers HD3: The Unstoppable Crawler for Your Farm!

Get ready to experience the sheer power and unwavering reliability of the Allis-Chalmers HD3! This legendary crawler tractor, built between 1960 and 1968, is a true workhorse designed to tackle the toughest agricultural challenges with ease. Based on the robust D15 farm tractor, the HD3 brings a legacy of durability and performance to your operations.

A Heartbeat of Power: The Allis Chalmers Engine

Under the hood, the HD3 boasts a formidable liquid-cooled, 4-cylinder diesel engine. With a displacement of 175 cubic inches (2.9 liters) and a bore/stroke of 3.562x4.375 inches, this engine delivers a consistent 36 horsepower at a steady 1650 RPM. The Roosa-Master injection pump ensures efficient fuel delivery, while the oil bath air cleaner and a generous 9-quart coolant capacity guarantee optimal performance even under demanding conditions. Starting is a breeze with its electric starter, all powered by a 12-volt system.

Master Your Terrain: Transmission and Drivetrain

Adaptability is key, and the HD3 delivers! Choose between a versatile two-speed power shift transmission, offering a total of 8 forward and 2 reverse gears, or a straightforward 4-speed mechanical shuttle transmission. The Power Director option features durable dry disc clutches for gear changes, while the Power Director itself utilizes reliable wet disc clutches. Steering is managed by mechanical clutches, and the mechanical contracting band brakes provide dependable stopping power, ensuring you stay in complete control.

Hydraulic Muscle for Your Implements

Equip your HD3 for any task with its capable open center hydraulic system. The pump delivers a robust 15 GPM (56.8 LPM) flow, with an optional higher flow available, and the system holds a substantial 16.5-gallon (62.5 L) capacity. With the ability to support one to three hydraulic valves, this tractor is ready to power a wide array of implements, making it an invaluable asset on your farm.

Built to Last: Dimensions and Stability

Stability and durability are hallmarks of the HD3. Weighing in at a substantial 7645 lbs (3467 kg), this crawler tractor provides a solid foundation for heavy work. Its 7-inch tracks ensure excellent traction and weight distribution across varied terrain, minimizing ground pressure and maximizing grip. This robust construction means the HD3 is built for the long haul.
