Abstract: A mower apparatus and method for making the same is provided. A mower apparatus may include a multi-wheel drive mower system having at least one mower blade and at least one front wheel positioned proximate the front of the mower system and at least one rear wheel positioned proximate the rear of the mower system. The mower apparatus may also include a zero turn assembly haying at least one caster wheel. The zero turn assembly may be rotatably attached to the multi-wheel drive mower system to provide the mower apparatus with the capability of operating in either a multi-wheel drive mode having at least the at least one front wheel and the at least one rear wheel engaging the ground or a zero turn radius mode having only the at least one caster wheel and the at least one rear wheel engaging the ground.

Abstract: Variable displacement pump pumps oil to one or the other ports of an oil operated vehicle wheel motor to drive a lawn mower.

Abstract: Gear box oil pumping system employs the teeth of a gear rotatably mounted within a gear box housing acting as paddles to move oil between the gear box housing and an oil reservoir.

Abstract: Grass blower for use with lawn mower, comprising rotating blade assembly in housing. Housing receives grass cuttings discharged from deck of lawn mower. Rotating blade assembly blows grass cuttings in housing into entrance of discharge chute.

Abstract: A lawn mower is powered by two vertical shaft engines mounted on the chassis and equispaced about the longitudinal axis of the chassis. A vertical drive shaft is rotatably mounted on the longitudinal axis of the chassis. The outputs of both vertical shaft engines are transmitted through belts and pulleys to the vertical drive shaft, which is rotated by the combined outputs of both vertical shaft engines. Other pulleys are secured to the vertical drive shaft and connected through belting to pulleys which rotate grass-cutting blades and to pulleys which operate motors turning the driving wheels to propel the lawn mower.

Abstract: The exit end of the discharge chute of a riding lawn mower having rotating grass-cutting blades is provided with a rotatable deflector plate, the position of which is controlled through a linkage by the operator of the lawn mower while seated and without stopping the lawn mower. The operator, through the linkage, can shift the deflector plate between an operative position closing the exit end of the discharge chute, an inoperative position opening the said exit end, and positions therebetween. The deflector plate is provided with apertures of size and spacing sufficient to prevent the passage therethrough of stones large enough to cause physical injury to persons or damage to property in the vicinity of the exit end, while permitting the passage therethrough of grass cuttings, small stones having no potential to cause such physical injury or property damage, and air forced through the discharge chute by action of the grass-cutting blades.

Abstract: A plurality of heavy chains in lateral contact with adjacent chains is secured to a structural member such as an angle which, in turn, is removably secured to the rear of the frame of a lawn mower, behind the grass cutting mechanism, the chains being heavy enough and long enough to drag along a grass lawn, whereby the grass lawn can simultaneously be cut and striped.
