GANG LAWN MOWER WITH SELF-SHARPENING MEANS

摘要

A gang lawn mowing machine having a tractor with a prime mover and ground supporting wheels. A plurality of mowers are supported on the tractor and are driven by the tractor in the cutting action of the mowers so that the mowers are powered. Pivot mountings support the mowers on the tractor for articulation of the mowers to adjust to irregular ground and for raising the mowers to a transport position compact with the tractor. A mower cutter drive train extends between the tractor prime mover and each of the mowers for rotating the mower cutter in a mowing direction of rotation. A reversing drive exists between the prime mover and the mowers for reversing the direction of rotation of the mower cutters and thereby sharpening the cutters when they are rotated in the reverse direction.
