What is a cat 0 tractor?

A Cat 0 tractor is a Category 0 tractor, which refers to garden tractors and small sub-compact tractors under 20 horsepower that use the smallest standardized three-point hitch size for attaching implements. Category 0 is smaller than Category 1 and is designed for lawn and garden work rather than farm work. Specifications for Cat 0 include lower link pins 5/8 inch diameter, top link pin 1/2 inch diameter, spacing between lower links about 20 inches, and very low lift capacity typically 500 to 1000 pounds. Cat 0 tractors are typically used with small implements like 3 to 4 foot mowers, small tillers, and garden plows for home gardens and estate maintenance. They are often found on brands like John Deere garden tractors, Cub Cadet, and older small Kubota models. Because Cat 0 is less common today, many modern sub-compact tractors use limited Category 1 hitch instead, which is slightly larger but can handle Cat 0 implements with bushings. The term Cat 0 tractor is sometimes used loosely to describe any small garden tractor with three-point hitch capability. It is distinct from zero-turn mowers which have no hitch. If you have a Cat 0 tractor, implement selection is limited compared to Cat 1, and you must ensure implements are lightweight enough not to overload hydraulics or cause front end to lift, which is safety concern on such small machines.
