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.

An attachment with cutting discs for use with a prime mover to cut ground material comprises a frame with forward and rear ends, a mounting portion at the rear end which is configured for coupling to a pivotal mounting member of the prime mover which is carried at forward ends of pivotal arms of the prime mover that can be raised or lowered, and a cutting portion at the forward end of the frame comprising a single transversely extending row of cutting discs arranged to cut the ground material in a forward working direction of movement of the prime mover. The single row of cutting discs is spaced from the mounting portion at a prescribed distance of about 4.5-5.5 feet such that cantilever action of the row of discs about the mounting member provides effective cutting action. The attachment includes shields covering the cutting discs.

A mower comprising a vehicle, a plurality of cutting assemblies, and an automatic height of cut control system is described. In some aspects, the automatic height of cut control system is configured to automatically change the height of cut for the plurality of cutting assemblies while maintaining the attitude of each cutting blade as the blade moves from a first height of cut to a second height of cut. In some aspects, the cutting assemblies include a variable-length member linked to a four-bar linkage configured to cause a change in the height of cut in response to a change in length of the variable-length member.

An autonomous robotic lawnmower (1) is disclosed. The robotic lawnmower (1) comprises a driving unit (3) comprising one or more drive wheels (5) and a cutting unit (7) arranged to cut grass when in a cutting position relative a ground surface (9). The lawnmower (1) further comprises a folding mechanism (11) allowing the cutting unit (7) to be pivoted relative the driving unit (3) around a pivot axis (ax) from the cutting position to a pivoted position.

A height adjustment system for adjusting a cutting deck height of a front mounted cutting deck (50) of a riding lawn care vehicle (10) may include a lever (155) operable by an operator seated on the riding lawn care vehicle, and a height adjustment assembly (150) that is alternately assembled and disassembled during attachment and removal of the cutting deck without any operator interaction other than positioning of the lever.

The present invention provides a ground-contour-following autonomous obstacle avoidance mower for hillside orchards and a control method thereof. Through cooperation of a push rod motor and a rotating pair, multi-angle cutting is achieved, and energy consumption needed by mowing operation is reduced. A connecting rod is arranged and forms a flexible mechanism together with an upper base bearing, a lower base bearing and a base-connecting unthreaded shaft. The flexible mechanism interacts with the push rod motor to achieve ground contour following operation, so that the mower as a whole can conduct ground-contour-following mowing operation on a complex orchard terrain, with a better cutting effect than that of a traditional mower. The use of a right-angle bypassing obstacle avoidance mode realizes precise obstacle avoidance of the mower, and achieves the operation purpose of not excessively relying on operators.

A front mower for mounting on a front three point linkage of a tractor to be operated for cutting vegetation, such as grass, in front of the tractor, the mower comprising: (i) a headstock for mounting on the front three point linkage of the tractor; (ii) a mowing head comprising an array of cutting heads for cutting vegetation such as grass, mounted on and moveable relative to the headstock to follow the contours of the ground over which the mower is passing; (iii) a mounting mechanism mounting the mowing head to the headstock, wherein the mounting mechanism comprises a cutting angle adjustment mechanism comprising an arc shaped guide and a follower for the arc shaped guide, the follower being moveable back and forth along the arc shaped guide, so that the cutting angle adjustment mechanism allows the mowing head to move back and forth along an arc defined by the guide and relative to the headstock so as to vary the cutting angle of the cutting heads. This allows for free movement of the mowing head to follow the contours of the ground.

In general, the subject matter described in this disclosure can be embodied in a robotic mowing device that includes a main body, a left-side driving wheel, a right-side driving wheel, and one or more motors to drive the left-side driving wheel and the right-side driving wheel to cause the left-side driving wheel and the right-side driving wheel to turn. The robotic mowing device also includes a deployable propulsion device that includes a rolling member and that is adapted to actuate the rolling member between a deployed state in which the rolling member is adapted to contact the ground surface, and a retracted state in which the rolling member is held apart from the ground surface.

A riding yard maintenance vehicle includes a frame to which front wheels and rear wheels of the riding yard maintenance vehicle are attachable, a steering assembly configured to receive steering inputs by an operator of the riding yard maintenance vehicle, and a mounting assembly disposed at a front end of the riding yard maintenance vehicle to which a working assembly is attachable. The working assembly receives electrical power via a plug assembly and is configured to transition between a working position and a maintenance position while operably coupled to the mounting assembly. The mounting assembly includes a locking assembly configured to prevent the transition from the working position to the maintenance position while the plug assembly provides power to the working assembly.

A mower comprises a frame carrying a front mounted rotary cutting deck. A deck lift moves the cutting deck between mowing and transport positions. The cutting deck can be selectively pivoted on the deck lift into a substantially tipped up service position to expose the underside of the cutting deck for service. The cutting deck has a self-engaging latch to hold it in its service position. A self-engaging catch provides a temporary hold position for the cutting deck that is short of the transport position as the cutting deck is being returned from the service position to prevent inadvertent contact between the cutting deck and the user. For ease of use, both the latch and the catch are releasable by a user from one side of the cutting deck which side also includes a rear foot pad and a front hand grip on the cutting deck.
