The present disclosure relates to forestry mulching or mowing heads with an upper frame and a lower frame having a rotatable cutting drum. The lower frame is pivotably mounted to the upper frame via a tilting mechanism. The tilting mechanism can include an actuator configured to pivot or tilt the lower frame relative to the upper frame. The tilting mechanism can include a bracket and a link that provides at least five independent degrees of freedom to pivot or rotate the lower frame relative to the upper frame. The tilting mechanism can provide a tilt capability of up to 180? while maintaining a pivot distance to cutting diameter ratio of less than 1 (the pivot distance being a distance between the frame pivot point and a rotational axis of the cutting drum and the cutting diameter being a diameter between cutting edges of the cutting tools on the cutting drum).

A crop forming assembly having a top plate with a first side and a second side, an arc-shaped cutout defined through the top plate, a forming shield pivotally coupled to the top plate and positioned on the second side, and a motor removably coupled to the top plate and configured to engage the forming shield. Wherein, the motor engages the forming shield to reposition the forming shield along the arc-shaped cutout.

A walk reel mower has a traction frame that carries a handle assembly to accommodate users of different heights. A pivotal bail on the handle assembly allows the user to slip a traction clutch to temporarily slow the mower down when turning the mower around. The handle assembly has a resilient isolator that acts in shear to permit the traction frame of the mower to maintain the quality and the height of cut when operated by users having a heavy downpressure touch on the handle assembly. A fixed head reel cutting unit or a flex head reel cutting unit can be interchangeably carried on the traction frame using a common mount therefor. Backlapping can be accomplished in situ by using an idler wheel between a driven transport wheel and the reel of the cutting unit to reverse the direction of the reel.

An autonomous traveling work apparatus includes traveling wheels, a control unit, a first work unit, and a second work unit. The first work unit includes a first rotary blade assembly rotatably supported by a vehicle body, and the second work unit includes a second rotary blade assembly rotatably supported by the vehicle body. The rotation center of the first rotary blade assembly is oriented in a first direction intersecting the horizontal direction. The rotation center of the second rotary blade assembly is oriented in a second direction intersecting the vertical direction and different from the first direction. The first rotary blade assembly and the second rotary blade assembly are lined up in the front-rear direction of the vehicle body on one of a left side or a right side of the vehicle body.

A system and method for independent suspension for a mower, including a frame having a front structural member and respective side structural members, a first front wheel assembly, and a second front wheel assembly. The system also includes a first suspension arm pair having a first suspension arm and a second suspension arm, each pivotably coupled at one end to the front structural member and at another end to the first wheel front assembly such that the second suspension arm is vertically offset from the first suspension arm. The system also includes a second suspension arm pair having a third suspension arm and a fourth suspension arm, each pivotably coupled at one end to the front structural member and at another end to the second front wheel assembly such that the fourth suspension arm is vertically offset from the third suspension arm.

An apparatus includes a first inverter circuit and a second inverter circuit. The first invertor circuit is configured to couple an alternator and a load device to deliver a driving signal from the alternator to the load device. The second invertor circuit is configured to couple the alternator to the load device to deliver a driving signal from the alternator to the load device and configured to couple a battery to the alternator to deliver a charging signal from the alternator the battery.

An attachable canopy for a riding lawnmower for providing a shading mechanism for a user seated on such a lawnmower includes a harness formed from a wrap around elongated strap that has a first end that is connectable to a second end, a frame which includes two elongated rods whose proximal ends are connected to opposite sides of the harness, and a canopy which is connected to the distal ends of the rods. The harness is adjustable so as to be attachable to either the seat or seat back of a riding lawnmower. In this regard, the rods which form the frame may selectively swivel at least ninety degrees so as to remain in a perpendicular orientation relative to the seat with the canopy held over the seat regardless of which structure the harness is attached to.
