US Patent 7797917 Bi-directional multi-blade mower housing apparatus

The mower housing apparatus provides a three-blade design provides with all blades rotating in the same direction, either clockwise or counterclockwise, at the operator's discretion. The housing provides hydraulically operated housing doors, so that grass and debris can exit either side of the housing. Blade directional control and side exit choice allows an operator to travel immediately adjacent to any obstacle in either travel direction and continue to mow successfully. Consequently, an operator need not make loops and extra trips around and across a lawn in order to mow successfully. The housing apparatus also provides a hydraulic motor for quiet, efficient operation, with a minimum of 550 inch pounds of torque. Additionally, the apparatus includes a blade attachment that provides superior lift of grass and debris. A pair of each removable attachment is quickly attached to and detached from each blade.
