A lawn mower includes a cutter blade having flaps and a flap drive mechanism. The flap drive mechanism includes a flap drive source and an intermediate power transmission unit. The intermediate power transmission unit is provided on a power transmission path between the flap drive source and the flaps and provided coaxially with a blade rotation axis. An output axis of a motor is provided coaxially with a blade rotation axis and the intermediate power transmission unit.

An autonomous robotic lawnmower (1) is disclosed comprising a driving unit (3) comprising one or more drive wheels (5), and a cutting unit (7) configured to cut grass during operation of the lawnmower (1). The cutting unit (7) comprises one or more support wheels (9) configured to support the cutting unit (7) by abutting against a ground surface (11) during operation of the lawnmower (1). The cutting unit (7) is movably arranged relative to the driving unit (3). The lawnmower (1) comprises a suspension assembly (13, 13′) configured to progressively limit movement between the cutting unit (7) and the driving unit (3) during operation of the lawnmower (1).

A removably attachable adjustable cutting apparatus and method includes a cutting deck, a mounting plate, a main pivot point in the mounting plate and a main adjustable arm with a first end connected with the mounting plate at the main pivot point and with a second end connected with the cutting deck such that the cutting deck is adjustable from a horizontal to a vertical position and positions in between.

A method and apparatus for attaching a forward-mounted implement that may allow pivotal movement of the implement around a longitudinal axis to better maintain proper operational height when operating on uneven or sloped terrain. Further provided, the attachment mechanism of the present disclosure may allow for a secure and safe attachment to an associated tractor or other similar vehicle while simultaneously providing for a reduced production cost and less maintenance requirements.

A wide area mower with an open-box structure mower deck. The deck has a width from the left to right side of about 72 to 120 inches. The deck's length is about 24 to 70 inches. A left and right front wheel are positioned in front of the deck. The wide mower deck will flex, twist, or bend when one of the left or right wheels travels over uneven terrain while the rest of the mower travels over substantially level terrain. A cutting height adjustment mechanism is provided on the mower that allows an operator to raise or lower an entire left side or an entire right side of the mower deck to a selected cutting height. This is done simply by disengaging a locking mechanism and manipulating a lever on a four-bar linkage attached to each side of the deck and then re-engaging the locking mechanism.

A strand trimmer and method of use thereof. The strand trimmer includes a pair of pivotable arms each having a motor, a follower wheel, and a cutter-spindle assembly disposed thereon. The arms are biased toward one another and are guided by the follower wheels to pivot around obstacles passing between the arms. The motor rotates the cutter-spindle assembly to move cutting strands extending therefrom through a cutting path with sufficient rotational velocity to cut vegetation. The cutter-spindle assembly includes a reloadable spool and a strand-feed mechanism. The strand-feed mechanism includes a solenoid actuated plunger within a shaft of the cutter-spindle assembly which operates to non-contactingly actuate the plunger to feed out a length of strand. The solenoid is non-rotatably carried on the trimmer arm while the shaft of the cutter-spindle assembly is encircled by and rotated within the solenoid.
