It has a power output of 85hp / 63.4kW and a compression ratio of 17.5:1. The engine has a rated RPM of 2200 and a firing order of 1-3-4-2. The starter volts are 12 and the oil capacity is 12qts / 11.4L. The coolant capacity is 13.75qts / 13.0L. The intake valve clearance is 0.016inches / 0.406 mm (cold) and the exhaust valve clearance is 0.019inches / 0.483 mm (cold).

Transmission

The transmission is an 8-speed unsynchronized gear with four gears, plus reverse, in two ranges. The tractor must be stopped, and clutch used, before shifting gear or range. The engine has a power output of 85hp / 63.4kW and a PTO (claimed) of 76hp / 56.7kW. The transmission is designed to work with this engine. The transmission is unsynchronized, which means that the gears are not synchronized, and the operator must match the speed of the engine to the speed of the tractor when shifting gears. The transmission is reliable and easy to use.

Brakes

The brakes are wet disc brakes. The Ford diesel 4-cylinder liquid-cooled engine powers the brakes. The engine has a power output of 85hp / 63.4kW, which provides enough power to stop the tractor quickly. The brakes are reliable and easy to use. The displacement of the engine is 304ci / 5.0L, which provides enough power to operate the brakes effectively.

Steering

The steering is hydrostatic power steering. The Ford 5.0L 4-cyl diesel engine powers the steering. The engine has a power output of 85hp / 63.4kW, which provides enough power to operate the steering effectively. The hydrostatic power steering is reliable and easy to use. The steering is designed to work with this engine.

Common Problems
