A lawn mower includes a seat plate movably coupled to the frame. An operator seat is coupled to the seat plate. An armrest is laterally spaced from the operator seat and includes an elongated support, an arm support surface, and a control panel. The elongated support has a first end fixed to the seat plate and a second end. The arm support surface is coupled to the second end and can support a user's arm. The control panel is positioned between the arm support surface and the second end of the elongated support. The control panel is fixed to the elongated support for movement with the seat plate such that the control panel remains stationary relative to the seat plate. The control panel includes an actuator to control a function of the lawn mower. The actuator is configured to be actuated while the user's arm is on the support surface.

A concave section for a harvester is provided. The concave section includes a concave body having an upstream side, a downstream side, a leading end and a trailing end. The concave body defines an arcuate crop engagement face facing radially inwardly. A plurality of crop passage openings are defined through the arcuate crop engagement face. A cover is configured to at least partially cover at least some of the crop passage openings. The cover is carried by the concave body and is movable thereon between at least two different positions to adjust a degree of openness of at least some of the crop passage openings.

A harvester includes a chassis, a separation frame movably supported by the chassis and upon which crop material is deposited, a reciprocating drive operably coupled to the separation frame to reciprocate the separation frame, a control system, a sensor programmed to produce a signal indicative of a tilt of the chassis relative to a gravitational direction, and programmed to provide the signal to the control system, and an adjustable link operably coupled between the separation frame and the chassis to adjust a pivot point of the separation frame. The control system is programmed to determine a change in tilt of the chassis based on the signal from the sensor. The controller is programmed to adjust the adjustable link to modify the pivot point of the separation frame in response to the change in tilt of the chassis.

A grass trimmer includes an operating device configured for a user to operate and a grass trimmer device including a grass trimmer head and a motor. The grass trimmer head includes a spool configured for a grass trimmer line to wind around and a housing formed with an accommodating cavity. When the grass trimmer is mounted with the grass trimmer line, a part of the grass trimmer line protruding outside the housing is defined as an effective part of the grass trimmer line. The grass trimmer further includes a controller configured to control the grass trimmer head to release a grass trimmer line when the grass trimmer head is mounted with the grass trimmer line and a length of the effective part is detected to be less than or equal to a preset value.

A mower combination including an agricultural vehicle and a number of mowing units suitable for cutting standing crop, including a front mowing unit and two lateral mowing units located behind and to the sides of the front mowing unit. Each of the lateral mowing units includes a conveyor to deposit cut crop as a swath. Sensors determine the slope and lateral displacement of each conveyor. A control unit receives inputs from the sensors and compares the inputs to a predetermined set of values of slope and, as indicated by the comparison, adjusts the lateral displacement of at least one conveyor.
