| An agricultural vehicle has an implement connection hitch including means for controllably moving the same relative to a rear axle of the vehicle. A control system controlling movement of the connection hitch is coupled with position determining means such as a GPS receiver and determines a location for the vehicle. During turning manoeuvres, the control system moves the hitch relative to the rear axle of the vehicle until it reaches an offset position such as to reduce the turning circle of the vehicle and a connected implement. The extent of offset may be determined automatically by the control system on identification of a connected implement. | ||||||

A second hydraulic motor causes the drive roller to rotate in a second direction opposite the first direction. When the agricultural implement is mounted to the plow, the dicing drum and drive roller are positioned rearwardly of the plow. The drive roller rotating in the second direction is operative to urge the agricultural implement to move in a direction towards the plow. | ||||||

| 94 | Rotary tiller attachments for facilitating turning | US619865 | 1990-11-29 | US5095996A | 1992-03-17 | Elbert P. Sprinkle |
| A conventional rotary tiller having an engine, an axle with two wheels, a set of tines, handlebars, and an attachment that facilitates turning. The attachment comprises a turntable which is mounted to the tiller opposite the tines in such a way that it remains out of contact with the ground during normal cultivation operations. Turning the tiller is accomplished by pivoting the tiller about the axle onto the turntable, and then rotating the tiller on the turntable to a new direction. The tiller is then pivoted back to resume normal operations in the new direction. | ||||||
