An electric mower includes: a body; a battery on the body; a cover including: a back wall backward of the battery; and a left side wall and a right side wall each extending forward from the back wall, the cover covering at least a portion of the battery; at least one motor drivable by the battery; and at least one controller disposed between the battery and at least one of the left and right side walls and configured to control the at least one motor.

A windrower with a frame at a front end of the windrower and a cab coupled to the frame. The cab has a plurality of controls disposed in the cab for controlling the windrower. The windrower also has a lift arm with a first end and a second end, the first end being pivotally coupled to the frame, wherein the lift arm includes a transverse bend defined at a location between the first and second ends. A first coupler is coupled to the second end of the lift arm and a second coupler coupled to the lift arm between the first and second ends. The first coupler is configured to couple the frame to a rotary-style head and the second coupler is configure to couple the frame to a draper-style head.

Systems and methods for automatically configuring a cutterbar between a flexible configuration and a rigid configuration in response to actuation of a gauge wheel are disclosed. The cutterbar is coupled to the gauge wheel such that extension of the gauge wheel causes the cutterbar to move into the rigid configuration and retraction of the gauge wheel causes the cutterbar to move into the flexible configuration.

Systems, methods, and apparatus for controlling a position of one or more float arms in response to operation of a gauge wheel or in response to an input are described. In some instances, a float arm is moved to a selected position automatically in response to extension or retraction of a gauge wheel. In some instances, a position of a float arm in an unlocked configuration is altered in response to an input, such as a user input. In some instances, a position of the float arm is controlled in response to application of fluid pressures, such as hydraulic pressure. Fluidic pressure may be altered in response to changing a position of one or more valves.

Systems, methods, and apparatus for controlling a position of one or more float arms in an unlocked configuration may include a first valve movable between a first position configured to cause the float arm to move to a locked configuration and a second position configured to cause the float arm to move to the unlocked configuration; a first source of pressurized fluid in communication with the first valve; and a second source of pressurized fluid in communication with the first valve. In the first position, the first valve may be configured to transmit the first fluid from the first source and, in response, to cause the float arm to move to the locked configuration. In the second position, the first valve may be configured to transmit the second fluid from the second fluid source and, in response, cause the float arm to move to the unlocked configuration.

An adjustable link for a flex wing cutter includes a first end portion, a second end portion, and a shaft. The first end portion provides first rotation about a first pin of the first end portion and second rotation about a second pin of the first end portion. The second end portion provides third rotation about a third pin of the second end portion and fourth rotation about a fourth pin of the second end portion. The shaft extends between the first end portion and the second end portion and is selectively repositionable relative to the first end portion to adjust a distance between the first end portion and the second end portion. The second end portion is configured to rotate about the shaft to provide a fifth rotation without adjusting the distance between the first end portion and the second end portion.

An adjustable skid shoe enabling a flexible cutter bar of an agricultural combine harvester to follow the ground at a higher cut height during the flex cutter bar mode. The adjustable skid shoe is hinged and can be fixed so the curved aft end lowers the ground contact surface beneath the header, raising the cut height in flex mode. The adjusted skid shoe contacts the ground further back from the cutter bar, allowing the cutter bar to reach close to the ground by a front pivot of the header on the adjusted skid shoe. Also, an agricultural vehicle header and an agricultural combine harvester comprising the skid shoe.
