A mower deck can’t cut grass unless it is connected to the tractor engine. This is usually done in one of two ways, with some possible permutations.
Riding mowers, lawn tractors, lawn and garden tractors, and garden tractors are large and powerful. They can be dangerous if not used safely.
It seems obvious that a wider or faster mower will cover a lawn faster than a narrower or slower mower, but this is not always true - and seldom will the increase in cutting rate be proportional to the increase in width or speed.
Hover mowers are rotary lawnmowers that have no wheels but rather ride on an air cushion.
