An agricultural harvester is disclosed. The agricultural harvester comprises a header. The header includes a frame, a control shaft connected to the frame, a flex arm, a linkage assembly and a cutter bar connected to the flex arm. The linkage assembly is movable between a first position and a second position. The linkage assembly includes a first end pivotably connected to the control shaft and a second end connected to the flex arm.

A concave section for a harvester 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.

This application belongs to the field of a garden tool and specifically relates to a garden tool including: a body; at least two traveling wheels located on two sides of the body; and a driving unit. The driving unit is installed inside the traveling wheel. In the present application, the driving unit is installed inside the rim. Therefore, the overall axial dimension of the traveling unit is reduced, the lateral width of the garden tool such as a mower is reduced. Under the same width conditions, more lateral space is available for the garden tool, allowing for the installation of structures such as battery compartments and standing platforms. This design lowers the center of gravity of the garden tool like a mower, thereby enhancing their stability.

Mowing systems include a mower and, optionally, a remote control unit such as a handheld unit, between which may be provided 1- or 2-way communications. Components and features are included in the mower, the remote control unit, or both to enhance the safety, functionality, or user experience of the system's user/operator. One aspect relates to automatically enabling the mower throttle and maintaining or reducing the throttle based on manipulation of a joystick Another aspect relates to a visual indicator of a state of a brake.

The configuration includes: a motor for driving a driving wheel (rear wheel) provided to a body; a slip ratio calculating section for calculating a slip ratio while the lawn mower is traveling; a friction coefficient calculating section for calculating a friction coefficient of a ground on which the lawn mower is traveling; a determination section for determining whether the ground on which the lawn mower is traveling is a lawn based on a relationship between the slip ratio and the friction coefficient and a drive controlling section for controlling the motor based on a determination result from the determination section. This configuration allows suitable driving operability for both of a case where the ground on which a lawn mowers traveling is a lawn and a case where the ground is other than a lawn.

A method of controlling an angular orientation of an agricultural combine having a chassis includes: determining a slope angle of the ground over which the combine is traveling; determining a tilt angle of the chassis; receiving an angle signal from an operator input device; combining the slope angle of the ground and the angle signal from the operator input device to calculate a desired angle of the chassis that is greater than horizontal (0) and less than the slope angle of the ground.

A lateral tilt control system for an agriculture harvester may include first and second tilt cylinders coupled between a support structure and an implement of the harvester. The first tilt cylinder may include a first cap-side chamber and a first rod-side chamber and the second tilt cylinder may include a second cap-side chamber and a second rod-side chamber. The system may also include a first fluid line providing a flow path between the first cap-side chamber and the second cap-side chamber and a second fluid line providing a flow path between the first rod-side chamber and the second cap-side chamber. Additionally, the system may include a pressure relief valve coupled between the first and second fluid lines to allow fluid to be transferred between the first and second fluid lines when a fluid pressure within either fluid line exceed a relief pressure setting.

A prescribed feedrate of material through the mobile harvesting machine and an actual feedrate of material through the mobile harvesting machine are detected, and a feedrate difference between the prescribed feedrate and the actual feedrate is identified. Wheel slippage of the mobile harvesting machine is also detected. Based on the feedrate difference between the prescribed feedrate and the actual feedrate and based on the detected wheel slippage, a speed control signal that controls speed of the mobile harvesting machine is generated.
