Introduction

Allis Chalmers HD11AG Series B Crawler Tractor

The Allis Chalmers HD11AG Series B is a heavy-duty crawler tractor produced between 1972 and 1974. Designed for demanding agricultural and industrial applications, this machine relies on its track-based propulsion system to deliver high tractive effort in challenging soil conditions.

Engine and Performance

The tractor is powered by a 516 cubic-inch (8.5 L) 6-cylinder turbocharged diesel engine. It generates a rated power of 126.5 hp (94.3 kW) at 1800 engine RPM. The engine utilizes a liquid-cooling system with a 41.6 L capacity and a dry-type air cleaner to ensure operational longevity. The drawbar power is rated at 106.2 hp (79.2 kW).

Transmission and Drivetrain

The HD11AG Series B features a gear-type transmission providing 6 forward and 3 reverse speeds. This configuration allows the operator to select the appropriate gear ratio for varying load requirements. The transmission system requires 70.0 L of oil for proper lubrication and operation.

Chassis and Dimensions

With an operating weight of 25,000 lbs (11,340 kg), this crawler provides significant stability for heavy-duty tasks. It is equipped with 18-inch tracks, which distribute the machine's weight to minimize ground pressure and improve traction on uneven or soft terrain. The operator station is of an open design, providing full visibility of the working area.

Electrical System

The machine is equipped with a 24-volt electric starting system to ensure reliable engine ignition. It includes an alternator-based charging system with a 20-amp output capacity to maintain the electrical load during operation.

Conclusion

The Allis Chalmers HD11AG Series B is a robust crawler tractor engineered for heavy-duty agricultural operations. Its combination of a high-torque turbocharged engine, substantial weight, and track-based traction makes it suitable for intensive tillage and heavy draft work.
