An apparatus for trimming plant material includes a rotatable tumbler through which the plant material is to be axially propagated while rotationally tumbling, and a plurality of cutting reel systems adjacent the tumbler. The plurality of cutting reel systems includes a first cutting reel system adjacent the tumbler, and a second cutting reel system adjacent a landing zone of the rotatable tumbler. The landing zone is an angular range about the axis of the tumbler within which plant material tends to land on the tumbler after tumbling through a central volume of the tumbler.

A mower for turf or lawn includes a frame for use on a tractor, or to form a structure of a trailer, and a plurality of cutting units, at least six, generally disposed side by side, each cutting unit including at least one roller for rolling on the ground. The mower includes lift means linking the cutting units to the frame and configured for articulating the cutting units between a mowing position and a non-mowing position. In the mowing position, the lift means are configured for pressing the cutting units against the ground in order to distribute, at least partially, the mower's weight on the ground via the rollers of the cutting units. The mower includes lateral articulated beams linking the cutting units. The beams are foldable inwardly and forwardly.

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 cylindrical turf treatment rotor adapted to be driven in rotation about a horizontal axis, and provided with wear-resistant teeth extending along one or more helical tracks on the rotor, the teeth being individually attached to the rotor so as to be capable of individual removal for replacement or refurbishing or for reconfiguring the rotor.

A mower provides a frame intended to be implemented on a tractor, or to form a structure of a trailer. The mower provides a plurality of cutting units (6), at least six, generally disposed side by side, each cutting unit (6) comprising at least one roller (44) intended to roll on the ground. The mower provides a lift assembly linking the cutting units (6) to the frame and configured for articulating the cutting units (6) between a mowing position and a non-mowing position. In the mowing position, the lift assembly is configured for pressing the cutting units (6) against the ground in order to distribute, at least partially, the mower's weight on the ground via the rollers (44) of the cutting units (6). The mower provides lateral articulated beams (10) linking the cutting units (6). The beams (10) are foldable inwardly and forwardly.

A walk reel mower has a pivotal rear traction drum that can be selectively disposed in two different mowing positions that allow a single mower to cut grass on golf course greens as well as tee boxes with no degradation in cutting or power performance. The reel cutting unit has a pivotal rear shield to allow the rear shield to be pivotally adjusted to maintain its radial spacing relative to the orbit of the reel at a desired amount as the reel diameter decreases due to wear. The ground speed of the walk reel mower is automatically slowed during turns of the mower by a mechanical cable assembly that links a user operable throttle control and throttle reducing control to a prime mover throttle. Finally, the leverage provided by the mower handle assembly when placed in a lowered position is used by the user to more easily deploy a kickstand.
