A mowing apparatus created by connecting a powered walk-behind mower to the side of a small tractor using a rigid articulated frame. The length of the frame provides the extended reach into the slope, allowing the tractor to stay on the flat terrain while mowing the adjacent steep slopes. The connection between the tractor and the mower is rigid in the horizontal directions, allowing the fine control of the mower position during the tractor movement both forward and in reverse, straight and turning, and articulated in the vertical direction, allowing the mower to follow the shape of the slope and preventing the transmission of the excessive side forces to the tractor, avoiding the risk of the tractor overturning. The apparatus allows the tractor and the mower to be quickly disconnected and used separately for their original purposes.
