A mulching apparatus including: a housing including a front opening and an inner wall; a rotor mounted in the front opening of the housing adjacent to the inner wall; and a liner mounting system for mounting a replaceable wear liner between the rotor and the inner wall, the liner mounting system including: an upper mounting provided at an upper edge of the inner wall, the upper mounting configured to releasably connect with the wear liner; and a lower mounting provided at a lower edge of the inner wall, the lower mounting configured to support the wear liner against the upper mounting and secure the wear liner to the inner wall.

Disclosed is a robot lawnmower including a body frame, a main wheel disposed on both sides of the body frame, a motor to drive the main wheel, a first edge blade provided in a region of the body frame corresponding to the main wheel and coupled to be rotatable with respect to the body frame by receiving a driving force of the motor, and a second edge blade disposed between the body frame and the main wheel to rotate together with the main wheel and cut a grass by a relative rotation of the first edge blade and the main wheel.

A method of autonomously controlling the ground speed of a harvester, such as a self-propelled or towed wind rower, uses both the engine speed and the header speed as control parameters to increase or decrease the ground speed as necessary to maintain efficient harvester operation over varying terrain and crop conditions. A control system includes a controller which receives signals from sensors indicative of engine speed, header speed and harvester ground speed and uses actuators to control the header speed, engine speed and harvester ground speed. An operator interface permits an operator to engage or disengage the autonomous mode of control system operation, as well as to directly control the harvester.

Some crops, such as soybeans, grow close to the ground, having a low canopy relative to that of weeds growing interspersed in the crop. A farm implement removes weed growth above the crop canopy. The implement has a chassis with at least three wheels connected to the chassis, a cutting mechanism, mounted at a front end of the chassis, a means for collecting weed growth cut by the cutting mechanism, mounted on the chassis, means for generating and selectively applying rotational torque to at least one of the at least three wheels and means for a user to guide the chassis down the rows in which the crop is grown.

A tool head for a hand-guided implement possesses two rotatably mounted tools, wherein a first tool is drivable via a first linkage and a second tool is drivable via a second linkage. The tools are drivable so that they rotate back and forth in opposite directions about a common rotational axis. The first linkage possesses a first drive member coupled to a first coupling member pivotably about a first link axis. The first coupling member is coupled to the first tool pivotably about a second link axis. The second linkage possesses a second drive member coupled to a second coupling member pivotably about a third link axis. The second coupling member is coupled to the second tool pivotably about a fourth link axis. The rotational axis of the tools and the coupling drive axis span a center plane, which runs between the second link axis and the fourth link axis.
