Abstract: A ground-engaging shoe assembly is provided for a power mower in which a mower blade is rotated in an upright shaft. The ground-engaging shoe includes a hub support assembly which is secured to the mower housing of the power mower. A ground-engaging shoe assembly is secured to a bearing housing which is located at the lower end of a hollow rotatable shaft, the ground-engaging shoe assembly including a bearing within which the hollow shaft rotates, whereby the ground-engaging shoe assembly is stationary. The bearing housing is adapted selectively to accept different ground-engaging shoes. An adjusting bolt extends through the hollow shaft and is secured at its lower end to the bearing housing An upper tower housing is adapted to transfer loading weight through the adjusting bolt to the bearings. The adjusting bolt is vertically-adjustably-secured at its upper end with respect to the upper tower housing by means of a locking-type nut.

Abstract: A transversely-mounted grass cutter mower combination with a vehicle is provided which is adapted to be activated to move laterally to the right or to the left with respect to its mounting to the vehicle and/or to move vertically up or down with respect to its mounting the vehicle. The vehicle is a motor-driven vehicle having front wheels and rear wheels and a longitudinally-extending frame bed therebetween. A transversely-mounted powered grass-cutting mower, having a mower housing and powered grass cutting blades which is mounted to the frame bed by means of a suspended mounting system. The suspended mounting system includes a cooperative linkage which is secured between the longitudinally-extending frame bed of the motor-driven vehicle and the mower housing. A first powered operator is provided for moving the mower housing, in cooperation with the constraints provided by the cooperative linkage, through an infinite number of vertical locations between an upper limit and a lower limit.
