    摘要： Provided is a riding lawn mower having good operability while securing safety even in backward movement traveling. In a riding lawn mower including a working machine 4 provided on a traveling vehicle body 1 and a forward and backward movement detection unit 94 configured to detect a forward movement operation or a backward movement operation of the traveling vehicle body 1. A control unit 100 is provided with a backward movement vehicle speed limit mode for limiting a vehicle speed when the working machine 4 is driven and the backward movement operation is detected. A traveling motor 30 that drives drive wheels 3 of the traveling vehicle body 1 is provided. The vehicle speed is limited by limiting a rotational speed of the traveling motor 30 to a predetermined value or less when the vehicle speed is limited in the backward movement vehicle speed limit mode. A vehicle speed limit release switch 105 configured to disable the backward movement vehicle speed limit mode is provided. The control unit 100 includes an acceleration value control unit configured to release a limit of the vehicle speed when the vehicle speed is limited in the backward movement vehicle speed limit mode and the vehicle speed limit release switch 105 is operated and control the vehicle speed so that an acceleration value does not exceed a certain value.

    摘要： The present invention relates to an apparatus (200) for motor control of a lawnmower including multiple blade motors (M1, M2, M3), a logic circuit (222) and a power circuit (223). The plurality of blade motors (M1, M2, M3) are coupled to the lawnmower (12) and configured for cutting vegetation. The logic circuit (222) is configured to receive a feedback signal from each of the plurality of blade motors and generate an output signal. The power circuit (223) is configured to drive each of the plurality of blade motors simultaneously in response to the output signal such that the speed of all of the plurality of blade motors is lowered when the feedback signal indicates that one of the plurality of blade motors has encountered an obstruction, clog, or another type of high load.

    摘要： In a mower (10) driven by a pair of electric motors (15), a battery (16) for supplying electric power to the electric motors is positioned in a space surrounded by the electric motors and a chute (30) for forwarding grass clippings to a grass collection bag (23). The chute extends rearward with an upward slant, and is bent in side view in such a manner that a lower part has a steeper incline than an upper part thereof.

    摘要： [Problem] To provide a hard-to-fall self-propelled mower which has a relatively simplified structure and an adjustable mowing width, is usable for a curved slope face, and enables a pruning work at a high place. [Solution] A self-propelled mower includes a self-propellable mover main body (10); at least one of a battery (11), an electric generator, and an engine, provided inside; a protruding wing (19) that protrudes sideward from sides of the mover main body (10), the protruding wing (19) being retractable and an extension length of the protruding wing (19) being variable; a plurality of mowing units (30) provided protruding from a front face of the mover main body (10) and a front face of the protruding wing (19), each mowing unit (30) including a movable blade (33) that reciprocates or rotates to cut grasses driven by an electric motor (37) or an engine, provided in each mowing unit (30), the electric motor (37) being powered by the battery (11) or the electric generator. The mover main body (10) moves on a slope face while being towed, via a traction rope (61), by a straddle-type mover body (4) that moves straddling on a guard rail (90) installed on a top of a slope of a bank; or moves on the ground or in the air while being suspended by a suspension rope (73) hung from a spanning cable (71) spanning in the air.

    摘要： A mowing device for the treatment of vegetations is adapted for the attachment to a carrier and for the connection to a drive unit. The mowing device includes a frame (22), on which mowing spindles (7a, 7b) are mounted which are provided on one side with mowing blades and on the opposite side with distributing elements for the connection to transmission members. On the frame (22), a transmission mechanism for driving the mowing spindles (7a, 7b) is further positioned. The mowing spindles (7a, 7b) are arranged in two mutually parallel rows, defined by longitudinal lines (8, 9), located in a mutual distance separation (L). The mowing spindles (7a, 7b) of each row are interconnected by means of the ' transmission members. The centres of the mowing spindles (7a) of the first row on a line (8) are located in a mutual spacing (P). The centres of the mowing spindles (7b) of the second row on the line (8) are located in the mutual spacing (P). The centres of the mowing spindles of the second row are offset in the direction of the lines (8, 9) by a one-half P/2 of the spacing P with respect to the centres of the mowing spindles (7a) of the first row on the line (8). A connecting line of the centre of each mowing spindle (7a) of the first row on the line (8) with the centre of the immediately adjacent mowing spindle (7b) of the second row on the line (9) forms with parallel longitudinal lines (8, 9) an acute angle (a), for which the following applies: L tg a = P/2 The size of the angle a is in the range from 15 ° to, 60 °. The transmission mechanism for driving the mowing spindles (7a, 7b) comprises two transmission devices mounted side by side on the frame (22) and mutually connected. The first transmission device is arranged for the rotation in one rotational direction and is connected via transmission members with the mowing spindles (7a) of the first row on the line (8). The second transmission device is arranged as a reverse device for an optional rotation of the output shaft of the gearbox (2) in both rotational directions, and it is associated via transmission members with the mowing spindles (7b) of the second row on the line (9).
