Abstract: A fence mower attached to an agricultural tractor having a 3 point hitch in which the fence mower is used for cutting and mowing vegetation under the lowest or closest horizontal rail of a fence line and to both sides of the fence line where a fence line is a series of vertical post secured in the ground and connected to one another by horizontal rails.

Abstract: A fence mower comprising a base frame connected to an agricultural tractor, a swing away cutting and dirt removal arm mounted by a pivot pin to the base frame to produce a mower assembly which is free floating by being connected to the agricultural tractor using a 3-point hitching system. Power to the invention is supplied by the tractor's power take off by way of a power take off shaft connected to a right angle gear box mounted on the swing away cutting arm. Through a pulley system, power is delivered to a spindle with a cutting and dirt removal blade attached on the bottom side. The swing away cutting and dirt removal arm is designed to extend beyond the side of the tractor, thus allowing the arm to be positioned under the last, or bottom fence rail closest to the ground of a fence. As the operator of the tractor engages the power take off, power generated is distributed to the cutting blade previously positioned under the fence line.
