Mowers may be front-mounted, rear-mounted or middle-mounted in terms of connection to the tractor. In terms of connection to the tractor, the common mowers in Iran are usually rear-mounted, which are connected to the three-point connection of the tractor, and their required power is provided through the gearbox and the power transmission axis of the tractor. The required power of the mowers is usually around 25-30 horsepower per meter of working width.
