A mower deck includes a top deck, a front wall, a rear wall opposite the front wall and a first side wall. The first side wall extends between the front and rear walls. A front baffle assembly extends downwardly from the top deck. The front baffle assembly extends from the first side wall toward a discharge opening that is positioned between the front and rear walls at a discharge side of the top deck. The front baffle assembly is configured to urge cut grass and debris toward the discharge opening. A discharge baffle is positioned proximate a rear end of the discharge opening and extends downwardly from the top deck. The discharge baffle and the rear wall define a discharge gap. The discharge gap is positioned on an opposite side of the discharge baffle from the discharge opening. The discharge gap is configured to allow airflow into the mower deck.

A mower folding-type chassis, comprising a fixing disc and at least one rotating disc rotationally connected with the fixing disc; the fixing disc is fixedly arranged at the bottom of the mower; mowing blades are respectively arranged within the shells of the fixing disc and the rotating disc; a driving device used for driving the mowing blades to rotate is arranged in the mower; when mowing a lawn, the rotating discs can be rotated and unfolded relative to the fixing disc, thereby improving the mowing efficiency, and when the mower needs to be stored or transported, the rotating discs can be rotated and folded relative to the fixing disc, thus reducing the space occupation of the mower.

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 deck level adjuster includes a pair of draft links connected to a frame of a grass mowing machine and pivotable to a plurality of different cutting heights using a foot pedal or hand lever for raising and lowering the mower deck. A pair of adjuster brackets may be attached to the pair of draft links and to a pair of deck brackets on the mower deck. Each adjuster bracket may be pivotable to a plurality of different positions relative to the draft links to secure the mower deck at a level position.

A grounds maintenance vehicle has an implement coupled to a vehicle frame. Some aspects relate to a height selection tool configured to change a vertical position of the implement relative to the frame. The height selection tool has a first pivotable shaft, a first bell crank rigidly coupled to the first shaft, a second bell crank pivotably coupled to the frame, and a first rigid linkage coupling the first bell crank and the second bell crank. A first spring has a first end fixed to the frame and a second end fixed to the first rigid linkage. Other aspects relate to a height selection tool that has a latch and a latch release. Yet other aspects relate to a bracket that pivotably couples two shafts to the vehicle frame, where the bracket allows pivoting of each of the shafts and fixes the locations of the shafts relative to each other.

A towed agricultural implement including a first headstock element for connection to a towing vehicle, a second headstock element supporting a chassis member provided with a plurality of working implements, a pivot pin for connecting the first headstock member and the second headstock member and defining a horizontal axis of rotation between the first headstock member and the second headstock member, in which the second headstock member has a lateral centre of gravity offset from the axis of rotation. A compensating structure is provided between the first headstock member and the second headstock member to offset the unbalanced loads caused by the lateral centre of gravity being offset from the axis of rotation.

A motorized turf trimming system and method with integrated control for a carrier vehicle and rotary trimming attachments is disclosed. The system can be configured for automatically trimming around stationary objects such as trees, signposts, guard rail posts, barrier posts, light bases, etc.

A string trimmer attachment apparatus and method for easy attachment to a lawn mower deck, without requiring the use of tools for attachment, by having an adjustable trimmer mounting platform which securely attaches to the lawn mower. A string-type powered trimmer motor on the bottom side of the adjustable trimmer mounting platform cuts the grass. An operating control located on the lawn mower controls the string-type powered trimmer motor. A pair of L brackets allow the adjustable trimmer mounting platform to firmly attach to the lawn mower without the need for a separate trimmer/edger appliance. No tools or lawn mower modifications are required to attach the adjustable trimmer mounting platform to the mower deck.

An agricultural machine includes a hitching support, at least one tool or group of tools, at least one support arm which is connected to the hitching support by a first joint and to the tool or tool group, and which is mounted so as to pivot about a transfer axis between operational and raised positions, and a safety device making it possible to carry out a safety movement under the effect of pressure. The safety device includes a lift connected to the hitching support by a second joint. The second joint is offset relative to the first joint in the direction of travel. The safety movement can include a second movement phase during which the lift is able to move the tool or the group of tools away from the ground.

A radio-controlled mower has a frame, an engine unit, rolling bodies configured to move the frame over an area of ground, a central cutting unit, and side cutting units. The frame and the side cutting units are mutually movable.
