Flail mower

Some smaller models are self-powered, but many are PTO driven implements, which can attach to the three-point hitches found on the rear of most tractors.

This type of mower is best used to provide a rough cut to long grass and even brambles in locations such as roadsides, where contact with loose debris may be possible.

The PTO driveshaft along the tractor's axis must make a right angle through the use of a gearbox in order to transfer its rotational energy to the drum.

There are also proprietary flails with various shapes for shredding larger brush and others that leave a smooth, finish cut.

This fact makes the flail mower best suited for areas where thrown objects would cause damage.
