Abstract
A single V-belt power transmission is provided for a three-spindle rotary mower without the belt crossing over itself or being subject to severe twists. The three spindles of the mower are disposed on vertical axes to form a triangular pattern with the lead or apex angle being forwardly of the other two spindles which are spaced laterally of one another. A swingable clutch idler and a fixed axis idler engage the flat backside of the V-belt and are so positioned on the mower housing that the single V-belt has a large arc of contact with the pulley on the central lead spindle and with a drive pulley positioned forwardly of the lead spindle. The idler pulleys also serve to so position the belt that there will be no contact between runs of the belt. The invention is illustrated in an underslung mower attachment for a riding tractor and includes an automatic brake, a manually operated height adjusting mechanism and a manual control for raising the mower to a transport position.
