A subcompact tractor often employs a diesel engine with two to three cylinders and 15 to 25 horsepower, whereas a small tractor typically employs a diesel engine with three to four cylinders and 25 to 45 horsepower. Both forms are deemed accessible and simple to use. Subcompact and compact tractors fall between garden and utility tractors in terms of total size and horsepower.
On a smaller frame, subcompact tractors possess the adaptability of larger tractors. In general, they are an excellent choice for areas greater than five acres or for activities including the transportation of multiple tonnes of rock, working with multiple tonnes of topsoil, mowing tough land, landscape grading, and the movement of huge quantities of snow. A subcompact tractor can lift around half of its own weight, transport a weight larger than its own, and push or pull many times its own weight. All subcompact tractors are equipped with a three-point hitch, four-wheel drive, and a diesel engine.
Compact tractors are adaptable enough to perform any task on a small land, with the only limitation being the size of the implements they can accommodate. Compact tractors utilise equipment from categories 1 or 2, whereas subcompact tractors utilise equipment from category 0. In contrast to subcompact tractors, compact tractors typically have a minimum ground clearance of 12 inches.
