Introduction
Allis Chalmers 170 Row-Crop Tractor
Produced between 1967 and 1973, the Allis Chalmers 170 is a row-crop tractor designed for varied agricultural applications. It belongs to a series of machines engineered for durability and operational flexibility during the late 1960s and 1970s.
Engine and Performance
The tractor is powered by a 226 cubic-inch (3.7 L) liquid-cooled engine, rated at 1800 RPM. It features a 4.00x4.50 inch bore and stroke with an 8:1 compression ratio. Maintenance specifications include a 6-quart oil capacity and a 15-quart coolant capacity, with a firing order of 1-2-4-3.
Transmission and Drivetrain
The 170 utilizes a Power Director transmission, providing 8 forward and 2 reverse gears. This system features a two-speed power shift, allowing the operator to shift between high and low ranges on the move without clutching. A neutral position on the Power Director lever allows the tractor to remain stationary while keeping the PTO engaged.
Hydraulics and PTO
Equipped with an open-center hydraulic system, the tractor delivers a pump flow of 18.3 gpm (69.3 lpm) at a pressure of 2000 psi. The hydraulic capacity is 6.5 gallons (24.6 L). The rear PTO is a live system operating at 540 RPM, providing consistent power to rear-mounted implements through a Type II hitch.
Mechanical and Dimensions
Built on a 95.5-inch wheelbase, the tractor measures 150.14 inches in length and 78 inches in width, with a ground clearance of 20.5 inches at the front axle. It features hydraulic power-assisted steering and mechanical contracting band and disc brakes on the differential for effective control.
Conclusion
With 9,303 units produced, the Allis Chalmers 170 is a mid-range row-crop tractor suited for farmers requiring a dependable, mechanically straightforward machine with the versatility of the Power Director transmission system.
