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.

Abstract: A cultivating implement has rows of tined soil working members that are freely rotatable about upwardly extending shafts. Each soil working member has tines positioned around the shaft which defines its axis of rotation. At the lower end of the shaft, a channelled feed member is attached and the shaft is hollow. Material from a container is dispensed from the container through the shaft and the feed member via a port to the ground being worked by the tines. The feed member is elongated and extends down, generally parallel to the tines of the corresponding soil working member which are mounted on circular plate supports. A further soil working member, preferably a supporting roller, is mounted behind the rows of soil working members.

Abstract: A soil working machine has an elongated frame portion that supports a row of soil working tools that extends transverse to the direction of travel. The machine is partly supported by rear wheels that are located adjacent the lateral sides of the machine and arms connect the wheels to an upper part of the machine. A delivery mechanism, including an elongated hopper is mounted on the implement and delivery tubes extend from the hopper to the ground, between the wheels and the soil working tools. The hopper is positioned above the frame portion and a rotatable member in the hopper is drivenly connected to the wheels.

Abstract: There is disclosed a dispensing apparatus which is mounted at the rear of a tractor and which employs two friction wheels mounted on a common frame. The frame is pivotally mounted so that an operator can cause the friction wheels to engage the rear wheels of the tractor. The friction wheels are attached to a rotatable shaft which contains a pulley. When the friction wheels engage the tractor wheels, the pulley rotates and by means of an associated belt, causes rotation of a dispensing cylinder associated with a cannister or hopper containing chemicals to be dispensed. Means are provided for adjusting the tension on the belt as well as for engaging said friction wheels in constant contact with the tractor wheels. The apparatus further incorporates a selectively actuated aerator assembly which is used in conjunction with the dispensing apparatus to maintain and perform lawn maintenance services.
