Abstract
An electrically or petrol driven cylinder mower comprises a mower body 101 and a grass box. An electric motor or petrol engine drives a cutter assembly 202, and also a turbo fan drawing air through an opening 207, both mounted in the body. The grass box has a mouth 204 over the cutters and an opening 302 which mates with the opening 207 in the mower body, and through which the turbo fan sucks air from the cutting region through the grass box. The air from the turbo fan is discharged within a skirt on the underside of the mower body to assist in supporting the mower above the ground. This skirt, and the land wheels and rear roller, lie behind the cutters, so as to avoid flattening the grass before it reaches the cutters. The land wheels are preferably inset, so that they run only on cut grass.
