A lawn mower includes a housing with a baffle that defines an air path to produce a cross-flow. The baffle includes a vent to manipulate air pressures within the housing and facilitate movement of plant clippings. A hand-held device for trimming with a rotary blade assembly may also include a housing that defines an air path to produce a cross-flow. The hand-held trimming device may also a baffle with a vent to facilitate movement of plant clippings.

The invention relates to a lawn maintenance machine comprising a container (10) and a movable wall (40), the movable wall (40) dividing the container (10) to a first storage (20) having a first length in a longitudinal direction, and a second storage (30) having a second length in the longitudinal direction, wherein the second storage (30) is placed rearward from the first storage (20), the lawn maintenance machine further comprising an actuator arrangement configured to move the movable wall (40) forward and backward in the longitudinal direction in order to increase and decrease, respectively, the volume of the second storage (30). The invention further relates to a method for taking care of a lawn or a turf. This invention further relates to a lawn maintenance method and a lawn maintenance system.

The disclosed subject matter is directed to a lawnmower that can include a cutter housing with a first chamber wall defining a first cutting chamber. A first discharge opening can be located in the chamber wall, and the cutter housing can include a slot arrangement. A conversion assembly can include an adjustable wall slidably attached to the cutter housing so as to be selectively movable within the slot arrangement between an opened position and a closed position to place the lawnmower in either a discharge mode or a mulch mode (or somewhere in between).

A fixed head walk reel mower has a frame supported for rolling over the ground. A reel cutting unit comprising a rotatable reel and a cooperating bedknife has a fixed orientation on the frame. The frame pivotally carries a ground engaging pivotal rear traction drum that can be selectively disposed in two different mowing positions when cutting grass at lower or higher height of cut ranges, respectively. This allows a single mower to cut grass at lower heights of cut on golf course greens as well as at higher heights of cut on tee boxes while minimizing degradation in cutting or power performance.

A mower system for mowing a field with a grass containing crop comprises a frame, a mowing device that is connected to the frame and has an adjustable mowing height, a sensor device arranged to sense a species composition related parameter, such as a ration grass-to-clover, of a part of the field, and to generate data based on the sensed parameter, and a control device that is operatively connected to the sensor device to receive the generated data, and is operatively connected to the mowing device and arranged to adjust the mowing height on the basis of the received data. This enables to adjust the mowing height dynamically, i.e. position dependently, based on the detected parameter. The mowing height influences the regrowth of e.g. grass and clover differently, so that the ratio can be influenced locally.

An agricultural vehicle header system having a center section, an inboard height sensor located on the center section between a lateral centerline and an end of the center section, a wing section movably attached to the end of the center section, a number of outboard height sensors located on the wing section between an inboard end and an outboard end of the wing section, and a header control subsystem. Each of the outboard height sensors is configured to output a respective outboard height sensor signal. The header control subsystem is operatively connected to the outboard height sensors, and configured to receive the respective outboard height sensor signals from each of the outboard height sensors, and generate a single emulated outboard height sensor signal based on the outboard height sensor signals.
