ABSTRACT:
An earthworking implement comprising a frame on which are supported front wheels, rear wheels and a rearmost dolly wheel. An aerator member with blades is rotatably secured to the frame between the front and rear wheels. The dolly wheel is mounted on the frame for rotation about a vertical axis at a location rearwards of the rear wheels. The front wheels and the dolly wheel represent endmost wheels on the frame. One of the endmost wheels is vertically movable with respect to the frame between raised and lowered positions, such that in the raised position the front wheels and dolly wheel define a common tangential plane which is at a level above the blades of the aerator member and below the rear wheels thereby establishing an operative aerating position whereas in the lowered position the front wheels and dolly wheel define a common tangential plane which is at a level below the aerator member and the rear wheels thereby establishing a transport position. A material dispenser can be positioned at the front of the frame for dispensing various materials onto the ground. The dispenser, front wheels and aerator can be power driven.
