LAWN MOWER PROPELLING DRIVE

摘要

A rotary lawn mower propelling drive wherein the mower has a housing supported by ground wheels which are propelled through the means of a prime mover, such as a gasoline engine. A drive belt extends from the engine and to a drive disc which is in rolling contact with a drive wheel which in turn is geared to a drive shaft connected to the powered ground wheels. The drive disc is a rubber or like material on the face which is in rolling contact with the drive wheel which is of a hard material, such as metal. The drive disc is movable across the plane of the drive wheel so that variable drive speeds can be achieved, and the drive disc is also movable away from rolling engagement with the drive wheel for selective disengaging of the drive. Controls are provided for both the variable speed and the disengagement mentioned. Further, the mower housing itself has a gear box integral therewith, and gears are rotatably supported in the integral gear box.
