There are included a passage portion provided at an upper surface portion of a mower deck, front and back slope portions and provided at front and back portions of the passage portion, front and back supporting portions supporting the slope portions in such a manner that the slope portions are movable in the front-back direction and swingable in the up-down direction, and front and back linking portions that are supported in such a manner as to be swingable in the front-back direction about axes extending in the left-right direction and that are connected with the slope portions. Operating the front and back linking portions in the front-back direction causes the front and back slope portions to be operated to the storage and use positions.

A mulching insert for use with a lawn mower having a frame and a cutting deck supported by the frame, includes a molded, single-piece body configured to be received in the cutting deck. The body includes an attachment portion that is configured to be engaged by a portion of the lawn mower to removably mount the body to the cutting deck. The body defines a mulching chamber within the cutting deck that provides clearance for a cutting blade of the lawn mower.

A high-efficiency blade for a lawn maintenance tool includes a central axis and a mounting portion located on the central axis. The high-efficiency blade includes a cutting blade and a cutting blade sharpened leading edge. A cleaning blade is vertically offset from the cutting blade and is configured to mulch the associated clippings from vegetation and reduce an associated accumulation of clippings on an underside of an associated mower deck. The lawn maintenance tool can also include a deck having a separation distance between the cleaning blade and an underside of the deck. The deck can include an elevation change to vary the separation distance. The deck and high-efficiency blade can also include a forward or rearward tilt.

A work vehicle comprising: a drive wheel unit that is provided in a vehicle body and is configured to be driven by a travel drive mechanism; a work unit that is provided in the vehicle body and is configured to perform work on a work target; a battery provided in the vehicle body; a motor that is configured to receive electric power from the battery and drive the work unit; an inclination sensor configured to detect an inclination of the vehicle body relative to a horizontal plane; and a first captured image acquisition unit configured to acquire a captured image that shows surroundings of the vehicle body when the work is being performed.

A lift detection arrangement in a robotic lawnmower for detecting a lift of a body of the robotic lawnmower relative to a chassis of the robotic lawnmower. The lift detection arrangement includes a collision absorber; and a sensor arrangement including a spring, a movable part, a metal plate and a sensor. The collision absorber is screwed to two plastic parts and arranged to allow a displacement of the body relative to the chassis in a collision plane during a collision between an obstacle and the robotic lawnmower, but not in a vertical direction. The moveable part is arranged to provide a displacement of the body relative to the chassis in a lift direction during a lift of the body. The sensor is configured to sense the distance to the metal plate that is fixed to the moveable part and to trigger a cut off of power to a cutting blade of the robotic lawnmower if the distance becomes greater than a predetermined distance.

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 lawn mower (10) includes a rotating shaft (16) that is connected to a lawn mowing motor (17) and extends in a substantially vertical direction; a blade (15) that rotates integrally with the rotating shaft (16); and a housing (18) that rotatably accommodates the blade (15) and has an open bottom. The housing (18) is provided with a grindstone (32) capable of coming into contact with the blade (15) from below the blade (15), and the grindstone (32) is capable of moving between a maintenance position where the grindstone is capable of coining into contact with the blade (15) and a standby position where the grindstone is not capable of coming into contact with the blade (15).

This invention relates to a system of lawn mowing and caring services. It comprises a lawn profile data information management system having lawn profile data stored therein; at least one mobile device for registered users, which communicates wirelessly with the lawn profile data information management system for requesting services; and at least one robotic lawn mower or lawn robot which works with the mobile device to acquire requisite lawn profile data from the lawn profile data information management system for the services before the robotic lawn mower or lawn robot can perform the requisite mowing or caring services on the specific piece of lawn.

The present invention is directed to a battery powered mower with a low profile design that minimizes the height of the mower to make the mower easier to operate and store. The low profile design places the cutting blade motor in the center of the deck volute so that it doesn't extend above the volute. Additionally, the batteries do not include a cover and so holes are located within the housing to drain away any water that collects. The invention also covers a simplified manufacturing process for the terminal blocks for the battery and a rear door. Lastly, the invention includes a cable guide to prevent the electrical cable from pinching when the handle is folded for storage.

A riding grass mower includes a driver seat 11 in a travel chassis 10, a mower deck 30 supported by the travel chassis 10, a rotary blade 20 in a glass-cutting space defined by side wall and a top plate 31 of the mower deck 30, a blade motor 4 configured to supply motive power to the rotary blade 20, and a blade motor control unit 55 configured to control the blade motor 4. The blade motor control unit 55 includes a main drive control unit 55a configured to rotate the rotary blade 20 forward, an auxiliary drive control unit 55b configured to rotate the rotary blade 20 backward, and a drive selection unit 55c configured to selectively operate the main drive control unit 55a and the auxiliary drive control unit 55b at a start of mowing with use of the rotary blade 20.
