Abstract
The specification discloses an improved garden tiller which, in addition to having power driven rotating tines on the front of the tiller transverse to the direction of travel, has a pair of free wheeling cultivator cylinders mounted to a stationary axle between the normal rear support wheels of the cultivator. The rear wheels can either be manually or power driven, and the forward motion of the machine turns the cylinders, on which radially extending vanes are mounted, to lift up the soil as they roll, and then release it, leaving little furrows in the soil which are good for planting and also keep the soil from drifting in the wind.
