Abstract
A reel cutting unit of a reel mower is provided with a belt and pulley drive system for rotating the reel of the cutting unit at variable speeds when the ground speed of the reel cutting unit is substantially constant to provide different clips. The drive system has three pulleys of different diameter in engagement with the belt in drive, driven and idler positions. The pulleys can be interchangeably used in any of the positions by moving the pulleys around into the different positions in six different possible arrangements. The pulleys are selectively placed in one arrangement at a time to select the clip provided by that arrangement. A chain and sprocket drive system with different diameter sprockets may be used in place of the belt and pulley drive system. The belt and pulley drive system may comprise toothed pulleys and toothed timing belt.
