US 2011/0209886 A1 · Device for Cultivating Soil or Brushing Debris

Abstract

A device for cultivating soil or brushing debris includes a frame supporting a transmission, a motor, and a shaft rotatably supported by a transmission housing and driven by the motor through the transmission. A distal end of the shaft includes a passageway therethrough. A fastener is at least partially received within the passageway. A tine assembly may be removably attached to the shaft and includes a first pair of two laterally spaced-apart tine disks. The first pair of tine disks being laterally positioned on the shaft between the fastener and the housing. A brush attachment may be removably attached, and includes a tube, which has a wheel rotatably attached to a first end thereof and a first gear fixedly attached to an opposing second end thereof. At least a portion of the fastener extends through at least a portion of the tube to fixedly attach the tube to the shaft.
