A system and method for actuating battery power for a mower that include receiving an input through a battery status switch of the battery. The system and method also include inputting a battery actuation switch based on receiving the input through the battery status switch. The system and method additionally include supplying an electronic signal to a microprocessor of the battery to supply power to a motor controller of the mower based on the input of the battery actuation switch. The system and method further include supplying electrical voltage to a motor of the mower to operate the motor based on the power supplied to the motor controller from the battery.

A mower's control system can maintain horizon maps that associate horizon features with known relative positions. When a mower's orientation is unknown, the control system can obtain an image that captures the horizon from the mower's current viewpoint. The control system can process the image to detect any horizon features that appear within the image and to determine their positions within the image. The control system can then access a horizon map to identify matching horizon features. The control system can compare the known relative positions of any matching horizon features with the positions of the horizon features within the image to thereby determine the mower's current orientation.

Removable seats and lawnmowers with removable seats are provided. A lawnmower includes a frame; a walking element coupled to the frame to move the lawnmower relative to an underlying ground surface; and a seat selectively coupled to the frame, the seat including: one or more rails; a lower support adjustably coupled to the one or more rails; a backrest coupled to the lower support; and a latch coupled to the lower support through at least one of the one or more rails, the latch being selectively engageable with the frame to maintain the seat in a riding position, wherein the seat is removable from the frame by rotating the seat about a horizontal axis.

A row unit for a header of an agricultural harvester. The row unit includes a frame, a first deck plate assembly mounted to the frame, and a second deck plate assembly mounted to the frame. The first and second deck plate assemblies each include a deck plate, a plurality of deck plate segments extending from the deck plate and moveable between a first position and a second position relative to the deck plate, and a plurality of biasing members for biasing each respective deck plate segment. The row unit includes both operator controlled macro adjustment and automatic micro adjustment of a gap between the first deck plate assembly and the second deck plate assembly. The micro adjustment is achieved through biasing members biasing each respective deck plate segment.

A drive-by-wire steering system for a power equipment device is provided. One example embodiment comprises a steering interface system, a power steering system, and a communication link connecting the steering interface system and power steering system. The power steering system can adjust steering angle of wheels of the power equipment device based on inputs received from the steering interface system. The steering interface system can receive user inputs and provide powered feedback and/or a simulated caster effect via a steering interface. Additional embodiments include power equipment devices and steering interface systems.

A radio-controlled vehicle includes a supporting structure, an engine unit, a kinetic unit and a remote control for operating the vehicle remotely, The radio-controlled vehicle also has a cab configured to house, in use, a person. The cab and the supporting structure are mutually movable with respect to each other to selectively arrange the cab in a desired position with respect to the supporting structure.

The mower unit includes a mower deck having a top wall and side walls extending downwards from an outer circumferential edge of the top wall, a rotational shaft extending upwards through the top wall from an inside space formed by the top wall and the side walls, a cutter blade attached to a lower portion of the rotational shaft within the inside space and rotatable together with the rotational shaft, an electric mower motor having an output shaft that can rotatably drive the rotational shaft, and a flywheel rotatable in association with the rotational driving of the mower motor.

An aerial lawnmower, including a main body, a mower assembly disposed on at least a portion of a first end of the main body to cut at least one vegetation in response to rotating, and a plurality of rotors disposed on at least a portion of a second end of the main body to perform at least one of increase and decrease an elevation of the main body in response to rotating.

A speed-adjustable self-propelled four-wheel-drive walk-behind lawn mower is provided. The lawn mower may include a cutting deck, an engine installed on the cutting deck including an engine shaft, and a cutting blade installed inside the cutting deck. The lawn mower further includes a first transmission box and a second transmission box. The lawn mower includes an engine pulley installed on the engine shaft, a first combined pulley in communication with the first transmission box, and a second combined pulley in communication with the second transmission box. The lawn mower includes a belt connecting the first combined pulley, the second combined pulley, and the engine pulley. The belt is configured to transmit, via the engine pulley, a driving force from the engine to the first combined pulley and the second combined pulley to rotate the first transmission box and the second transmission box.

A robotic vehicle (10) comprising a first chassis platform (200) comprising a first wheel assembly (202) and a second chassis platform (210) comprising a second wheel assembly (212). The first and second chassis platforms (200, 210) is arranged to be spaced apart from each other. The robotic vehicle (10) further comprises a linkage (220) operably coupled to the first chassis platform (200) and the second chassis platform (210). The linkage (220) being coupled so as to be fixed relative to the first chassis platform (200) and so that the second chassis platform (210) is rotatable relative to the first chassis platform (200), wherein the second chassis platform (210) comprises a turning axis (400). Said robotic vehicle (10) further comprising an electric brake (262) disposed proximate to a turning shaft (422) of the linkage (220). The electric brake (262) being selectively applied by processing circuitry (110) to resist turning of the second chassis platform (210) about the turning axis (400) and being selectively released to allow the second chassis platform (210) to turn about the turning axis (400).
