A mower includes a plurality of grass cutting units, either reel or rotary, arranged in a gang configuration. Each cutting unit is connected to the mower by a separate suspension that includes a lift and lower portion for lifting and lowering the cutting unit out of and into contact with the ground, respectively. The suspension includes a ground contour following portion permitting the cutting unit to have one or more degrees of freedom relative to the lift and lower portion to independently follow the ground contours the cutting unit encounters. A tuned mass damper is installed in the ground contour following portion of the suspension or is adjacent to a connection between the ground contour following portion and the lift and lower portion for damping undesired vertical bobbing of the cutting unit.

A stand on mower with multiple cutting units including a front cutting unit positioned behind a pair of front wheels extending laterally outwardly from a vehicle frame, and a pair of rear cutting units positioned behind the front cutting unit and extending laterally outwardly from under the vehicle frame. Each cutting unit is connected to a lift arm that raises and lowers the cutting unit between a mowing position and a transport position. A standing operator platform is positioned between a pair of traction drive wheels behind the pair of rear cutting units, with the platform positioned below the vehicle frame.

A triplex greensmower lift system includes a yoke mount attached to a reel cutting unit forwardly and below a center of gravity of the reel cutting unit, an upper lift arm attached to the yoke mount and extending rearwardly behind the reel cutting unit to a horizontal pivot axis on a lower lift arm located at a height between a top of the reel cutting unit and the center of gravity of the reel cutting unit, and a spring connected to the upper lift arm and biasing the upper lift arm upwardly and rearwardly to reduce ground pressure on the reel cutting unit.

A triplex greensmower open foot platform provides an opening in front of an operator seat providing visibility from the operator seat to a center reel cutting unit. The opening has sufficient dimensions for removal or installation of the center reel cutting unit or a grass catcher therethrough. A pair of platform sections provides a perimeter at least partially around the opening. Each of the platform sections including a footrest and a rearwardly extending coupling that is manually removable from the triplex greensmower.

A header for a combine harvester, the header including a frame mountable to a forward end of the combine harvester, at least one row unit mounted to the frame to receive and process stalks of corn, a stomping shoe mounted to the frame behind the row unit to flatten stalks of corn, and a stalk splitter mounted to frame behind the row unit to split stalks of corn. The face of the stomping shoe is provided with a plurality of structures to guide each stalk of corn along a predefined path on the face while the stalks of corn are flattened. The stalk splitter includes a disk blade biased against the ground for splitting stalks of corn after they are processed by row units of the corn header.

An adjustable lift rate system on a grass mowing machine such as a riding greensmower having a lift and lower circuit including a plurality of hydraulic lift cylinders to lift and lower a plurality of cutting units, and a controller providing a current to a proportional solenoid valve to bypass the hydraulic lift cylinders. An operator control may be used to adjust the current to the proportional solenoid valve to adjust the lift and lower rate of the cutting units.
