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.

A lawn mower includes a cutting element for cutting grass, a motor for driving the cutting element to rotate, a housing for containing the motor and a handle device for a user to control the lawn mower. The handle device includes a handle including a gripping portion for the user to grip and a connection portion substantially extending along a direction of a first line, and a first operating element for the user to operate. The first operating element is capable of rotating about a first axis relative to the handle. The first axis is substantially parallel to the first line.

A turfplaner is described comprising a rotational elongated cutter capable of independently altering a cut height of the rotational cutter based on a deviation between cut height and a desired cut profile. A hierarchical controller is in functional communication with the lift mechanism and a laser or GPS guidance system. The laser or GPS receiver is capable of receiving the planer laser beam or GPS signal and the hierarchical controller is capable of determining and minimizing a deviation between the cut height and the desired cut profile based on the laser or GPS receiver location relative to the planer laser beam or GPS signal. At least one autograde device and an autodepth device are in functional communication with the hierarchical controller to activate either on grade, below grade, or above grade control mode.

A cutting arrangement (2) configured to be attached to a lawnmower (1) to cut vegetation is disclosed. The cutting arrangement (2) comprises a cutting unit (4) configured to rotate in a first rotational direction (R) around a rotation axis (Ax) during operation, a cutting guard (3) comprising a top surface (13) and side walls (34), and a centre body (8) protruding from the 5 top surface (13). The centre body (8) is arranged such that the distance (d11, d12, d13) from the rotation axis (Ax) to radially outer delimiting surfaces (8.1, 8.2, 8.3) of the centre body (8) decreases continuously, seen in the first rotational direction (R), within a first angle (a1) having its vertex (v) at the rotation axis (Ax). The first angle (a1) exceeds 90 degrees or exceeds 180 degrees. The present disclosure further relates to a lawnmower (1) comprising 10 a cutting arrangement (2).

A disc cutter for an agricultural implement includes: a disc body configured to rotate in a rotation direction; a knife mount carried by the disc body and including a body mounting feature; and a knife coupled to the knife mount. The knife includes: a pair of cutting sections each having a knife mounting feature disposed on or in a knife surface between a pair of edges of the cutting sections and configured to couple with the body mounting feature, each of the edges defining a cutting angle with respect to the knife surface such that the edges extend in parallel.
