Abstract: A data processor determines whether a draft force on the implement is unbalanced based on an error between the observed implement angle and a target implement heading exceeding a threshold deviation. The data processor is adapted to generate a control signal to compensate for the imbalance in the draft force by adjusting the first lateral position via the first actuator, or by adjusting the second lateral position via the second actuator, the first actuator and the second actuator being positioned on opposite lateral sides of the implement.

Abstract: A lawn aerator has a series of tine assemblies spaced along a driven shaft driven by a motor. Each fine assembly has a plurality of tines for aeration extending in a substantially radial pattern about the driven shaft. The inner tine assemblies along the middle portion of the driven shaft are secured to the driven shaft to drive the aerator along the lawn as the driven shaft rotates. The outer tine assemblies adjacent to the ends of the driven shaft are rotatably mounted to the driven shaft. This permits the outer tine assemblies to rotate independently and thereby makes the aerator more maneuverable and easier to turn. Removable weights can be attached to either side of the aerator housing to help maintain a straight course when traversing a slope.

Abstract: A landscape leveling and raking apparatus has a frame, a handle protruding upwardly from the frame, a rake pivotally coupled to the frame to protrude downwardly and rearwardly therefrom, a screed fixed to the frame forwardly of the rake, a plurality of tiller blades rotatably mounted along a forward, open end of the frame, a motor which rotatably drives the tiller blades, and a mechanism for raising or lowering the tiler ,blades relative to the frame. As the blades rotate, they till the soil and propel the apparatus forward. The frame is open along its front edge. This allows soil to accumulate within the frame as the apparatus moves forward. The soil gradually escapes from the frame by passing beneath a screed fixed along the lower rear edge of the frame. The screed levels the soil before it is raked by the tines of the rake.

Abstract: The type of machine in which the invention finds maximum utility is the self-propelled, user-guided garden machine such as a rotary tiller. A typical machine of that genre has a straight-through axle without a differential and opposite ends of the axle project as right and left shafts to which right and left ground-engaging wheels are respectively affixed. The improvement provided by the present invention resides in right and left clutch-brake units arranged symmetrically at each side of and external to the transmission case. The keys normally fixing the wheels to their shafts are removed and the wheels are instead journalled on the respective shafts and the clutches are alternately engaged and disengaged between the shafts and wheels to facilitate steering of the machine. Each clutching unit includes a brake and controls are provided for effecting braking and clutch disengagement at either side of the machine.

Abstract: Transport carrier apparatus and techniques are described for transporting repair items to and from an agricultural pivot sprinkler device of the type used to irrigate row crops. The apparatus is self-propelled and includes: (a) a frame having an open front to receive repair items, (b) support area at the front of the frame to support the repair items being transported, (c) at least four wheels attached to the frame to support it above the ground, (d) a power source (e.g., a gasoline engine) for driving the wheels, and (e) handles on the rear portion of the frame for steering the apparatus. The transport apparatus is sufficiently narrow to enable it to travel between adjacent rows of growing row crops so that replacement wheels, gear boxes, etc. can be transported to and from a tower of the sprinkler system without trampling the crops. In a preferred embodiment the apparatus includes a transmission having forward and reverse gears.
