⚙️ Engine Specifications

Engine Manufacturer:

Allis Chalmers (or licensed manufacturer)

Engine Type:

Diesel

Engine Configuration:

Likely a 3 or 4-cylinder inline engine, common for tractors of this era and size.

Displacement:

Specific displacement would vary but likely in the 200-300 cubic inch range for this tractor class. (e.g., ~201-230 ci)

Horsepower Rated:

Rated horsepower would typically be in the range of 45-65 PTO horsepower, depending on the specific engine variant and configuration.

Torque Peak:

Torque figures would be optimized for pulling power, characteristic of diesel engines in this agricultural application.

Fuel Delivery System:

Typically equipped with a diesel injection pump (e.g., rotary or inline) and injectors.

Fuel Type:

Diesel Fuel

🔧 Transmission

Transmission Type Standard:

Likely a constant mesh manual transmission with multiple forward and reverse gears (e.g., 8-speed or 12-speed).

Transmission Type Optional:

May have been offered with a higher-spec transmission option, potentially including a partial powershift or creeper gear set.

Gear Selection:

Lever-based gear selection for various working speeds and a range selector for road or field operations.

Clutch Type:

Dual-stage dry clutch, allowing for independent operation of the transmission and PTO.

📐 Dimensions

Overall Length:

Approximate length would be in the range of 120-140 inches, excluding implements. (Specific dimensions vary).

Overall Width:

Width would vary depending on tire fitment, typically around 60-75 inches at the rear axle.

Wheelbase:

Wheelbase typically around 75-85 inches for stability.

Operating Weight:

Operating weight (without ballast) likely in the range of 4,500-6,000 lbs.

Drawbar Horsepower:

This is a performance metric, not a dimension, but reflects the tractor's pulling capability.
