ENGINE DETAIL
The Allis Chalmers 220 tractor features a robust AC-3500 turbocharged diesel engine with a large 7.0L capacity, offering excellent torque output and efficiency at a rated 2200 RPM, making it suitable for heavy agricultural tasks. The 16:1 compression ratio enhances power generation, while the dry paper element air cleaner provides effective filtration, maintaining engine longevity under dusty conditions. However, the weight and size of the engine could pose challenges in maneuverability and transportability in certain farming scenarios.

MECHANICAL
The Allis Chalmers 220 features a versatile drivetrain with options for both 2WD and 4WD, enhancing traction in various agricultural scenarios. Its hydrostatic power steering provides improved maneuverability, especially in tight spaces, while the dry disc brakes deliver reliable stopping power under load. The optional QCS cab introduced in 1972 offers operator comfort, although the open station can expose operators to elements, which may be a consideration depending on the working conditions.
