In one embodiment, a method comprising dampening movement of a cab supported by a chassis according to at least one dampening component; receiving plural inputs from at least one sensor and a seat suspension system; and based on the received plural inputs, causing an adjustment to the dampening movement of the cab according to the at least one dampening component.

A trimmer head that can be attached to trimmer stems of varied length includes a stem attachment point, a lift, a base, a pull and twist mechanism, a plurality of blade posts, and a plurality of resting cavities. The trimmer stem is attached to the stem attachment point. The stem attachment point is positioned in between the lift and the base allowing the trimmer head to receive longer trimmer stems. Trimmer blades or trimmer lines are attached to the plurality of blade posts. The lift and the base are positioned adjacent to each other. Moreover, the plurality of blade posts are oriented towards the base. By using the pull and twist mechanism, the trimmer blades or the trimmer lines are positioned in between the lift and the base. The lift is offset from the base providing a maximum range of motion for the attached trimmer blades or trimmer lines.

A cutting system for a harvesting header includes a transversely extending cutter bar. First and second transversely extending knife backs are supported in relation to the cutter bar and are axially aligned with each other in a transverse direction. The first and second knife backs may each have a main body portion. At least one knife section is mounted to each of the first and second knife backs, each knife section having at least one knife edge extending generally in a forward direction. The first knife back is not attached to said second knife back. A crop divider structure is interconnected to the cutter bar and is operationally positioned between said first and second knife backs. The cutting system may also include first and second knife heads interconnected to the first and second knife backs and operable for interconnecting a knife drive system to drive the first and second knife backs.

A battery assembly is disposed on a mowing vehicle having at least two electric drive assemblies. The battery assembly includes a plurality of battery packs joined together, where two of the battery packs are structurally connected to the vehicle frame and at least one other battery pack is structurally connected only to the first two battery packs to form a structural support for the vehicle. A fourth battery pack may be connected to and disposed below one of the other battery packs, and may be located between the two electric drive assemblies. A portion of the battery assembly may be located between an operator seat and a portion of the drive assemblies.

A cutting system for a harvesting header includes a transversely extending cutter bar, a transversely extending knife back, a knife section mounted to the knife back having a knife edge extending generally in a forward direction, a knife guard component having a front guard portion and a rear portion interconnected by a medial portion having a recess. The medial portion is configured for receiving a lengthwise portion of the knife back with the knife section being received into, and the knife section is operable to move transversely into and out of a cutting slot in the front guard portion. A hold down component is located between an upper surface of the rear portion of the knife guard component and an underneath surface of the cutter bar, and an attachment mechanism is operable to secure the knife guard component and the hold down component to the underneath surface of the cutter bar.

A cutting device is embodied for cutting agricultural crop plants by a rotational movement about a cutting rotation axis and has at least one knife element that, in a plan view of a top side of the cutting device, is embodied open in circulating direction. At least one radial conveying element, arranged at least at the top side and stationary relative to the knife element, is provided that at least in sections thereof is embodied for conveying the crop plants in a conveying direction that, relative to the cutting rotation axis, is oriented partly tangentially and partly radially relative to the cutting rotation axis. Moreover, a harvesting attachment with a plurality of such cutting devices and a field chopper with such a harvesting attachment is provided.
