    Abstract: A mechanical system attaches to a tractor and, upon activation of a hydraulic ram, rotates implement-engaging implement lift hooks to rotate an attached agricultural implement upwards towards 90 degrees for inspection and maintenance. The system can be secured in its raised and rotated position via a locking pin. The implement is returned to its original position through removal of the locking pin, reversal of the hydraulic ram and disconnection of the implement lift hooks.

    Abstract: A hydraulic or electric de-thatcher power lift assembly attachment that provides control while de-thatching because it is stable and efficient and can be lifted with ease at any time when dealing with difficult terrain. In an example embodiment, the hydraulic version fits hydraulic equipped tractors. In an alternative embodiment, the device may be used with an electric motor from the tractor, or can have its own dedicated battery for power. A hydraulic or electric lift assembly is also provided for a lawn aerator. The various attachments are designed to replace the standard manual lift lever on standard aerators. The attachments can be used on tractors that have hydraulics built into the tractor or on tractors with an electric motor.

    Abstract: A tractor control system, which controls an operating condition of an implement attached to the tractor. The control system includes a sensing means providing a force signal which indicates the pull force necessary to pull an implement in a desired position; a control which receives the force signal; and means for measuring at least one parameter associated with the tractor mode and/or the implement mode and the implement position is adjusted to a new position when the force signal varies. The control system includes pre-determined values associated with certain tractor and/or implement modes. A measured parameter is compared with a pre-determined parameter value and if the measured parameter would result in an undesired movement of the implement, the force signal is deactivated, or the response to the force signal is deactivated to prevent undesired movement of the attachment.

    Abstract: An adjustable row following guidance device for a tractor drawn row crop implement, includes a main support member disposed substantially transverse to the direction of travel of the implement as pulled by the tractor and having a first side and a second side, a first crank arm-assembly being releasably attachable to either of the first side and the second side, a second crank arm assembly being releasably attachable to either of the second side and the first side, the attachment of the crank arm assemblies to the main support member forming a generally inverted U-shape, each crank arm assembly including a laterally offset configuration, so that when the first crank arm assembly is attached to the first end, and the second crank arm assembly is attached to the second end, the device has a first implement width, and when the first and second crank arm assemblies are reversed on the main support member, the device has a second implement width, each crank arm assembly further including a forward portion with a tractor connection point, and a rearward portion with an implement connection point, the implement connection point being rearwardly pivotable relative to the tractor connection point.
