The tractor's engine is made by Caterpillar and has 4 cylinders. It's liquid-cooled, which helps keep it running smoothly in hot weather.

This tractor's engine is quite strong, with a displacement of 312.1 cubic inches. It has a bore of 4.25 inches and a stroke of 5.5 inches. The engine runs best at 1400 rpm, which is good for steady work. One special feature of the RD4 is that it comes in two different gauges: 44 inches and 60 inches.
