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 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.

A limb and branch trimming apparatus includes a frame having a support platform and an upstanding mast member; a cutting assembly having a plurality of cutting members, wherein the cutting members are rotatably connected at the mast member; and a power source for powering the cutting members independently from the vehicle's power source. The support platform of the limb and branch trimming apparatus is removably mountable to or near the top front portion of a vehicle. The apparatus is used for vertically cutting limbs, branches, and brush along a walkway, pathway, or trail where a tractor would typically be too large to navigate said pathway or trail.

A control system and method for adjusting a rotational speed of a header on an agricultural vehicle based on ground speed of the agricultural vehicle. The header may include a plurality of cutters rotatably actuated with a header actuator. The control system may have a processor that compares a ground speed of the agricultural vehicle with a threshold ground speed. If the ground speed of the agricultural vehicle is below the threshold ground speed, the processor may command the header actuator to rotate the cutters at a constant predetermined rotational speed. If the ground speed of the agricultural vehicle is above the threshold ground speed, the processor may command the header actuator to increase rotational speed of the cutters in proportion to the ground speed of the agricultural vehicle.

A conditioner roller vibration sensing mechanism having first and second rotatable conditioner rollers spaced apart in close proximity to each other and between which cut crop can be directed as the rollers rotate during operation. The first roller is shiftable with respect to the second roller for adjusting the spacing between the rollers. The rollers vibrate when the rollers are spaced in such close proximity to each other that they contact each other as they rotate. An arm pivotally mounted to a frame supports the first roller, and the frame supports the second roller. The arm is movable to shift the first roller with respect to the second roller. An accelerometer is operatively coupled to the rollers for sensing the vibration created when the first and second rollers are positioned so close to each other to contact each other.

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.

The present disclosure relates to a lawn mower (100) comprising a cutter propulsion unit (165), a transmission axle (166, 166′) that has a longitudinal extension (L, L′) and is adapted to be rotated by the cutter propulsion unit (165). The lawn mower (100) further comprises a cutting disc (160) that has a radial extension (R) that runs between a center (182) and an outer edge (181), where the cutting disc (160) comprises one or more cutting edges (161, 162, 163) that are adapted to cut grass when the cutting disc (160) is brought into a rotational motion by means of the transmission axle (166). The cutting disc (160) further comprises a connection portion (164, 164′) which is adapted to receive a coupling member (173, 173′), comprised in the transmission axle (166, 166′), in at least two different mounting positions that are adapted to position the connection portion (164) in mutually separated positions along the longitudinal extension (L, L′).

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 drive train for driving the rotor, the drive train including: a drive shaft connected to the rotor; a motor comprising a motor shaft; and a removable wear gear connecting the motor shaft and the drive shaft, wherein the wear gear is formed from a material that is softer than a material of the drive shaft or motor shaft.
