The invention generally relates to mowing of grass and other vegetation using heavy commercial mowers. More particularly, the invention relates to a waste collection, stowage, and disposal system for attachment to such a mower.
For high-volume commercial mowers, a tension exists between the speed at which a volume of vegetation may be cut and the difficulty of collecting, stowing, and disposing of this volume. At a high-volume rate, an operator may need to frequently return to a disposal site to offload mowed or otherwise collected vegetation from an onboard collector. For safety reasons, the mower may need to be shut down while the operator manually detaches and empties the collector. This increases mowing time and wastes fuel. If a user affixes a larger volume collector to the mower, the collector may become so heavy as to be difficult to remove and empty manually, leading to potential damage to the mower or injury to the operator. A towed or otherwise self-supporting collector may be difficult to maneuver, especially on sloping or otherwise uneven ground, and prohibitively complicated, expensive, and bulky, especially for a small business. A towed collector increases the difficulty of moving the mower in reverse due to the tendency of a trailer to jackknife when reversed.
Accordingly, there is still room for improvement in the art of collecting, stowing, and disposing of mowed vegetation.

Referring to
The collection system 100 is depicted in
The collector 110 is a container with an interior volume formed between a mounting panel 111, a top panel 114, a bottom panel 115, a rear panel 116, and at least one side panel 117. The collector 110 of the example embodiment is of a welded steel construction, with at least the top panel 114, bottom panel 115, and side panel 117 being permanently joined together. In other embodiments, the collector 110 is constructed from aluminum, steel, plastic, or any combination, and may be constructed using molding, machining, welding, or any combination thereof. The mounting panel 111 is rotatably connected to the top panel 114 by at least one hinge 113. At least one of the mounting panel 111, top panel 114, bottom panel 115, rear panel 116, and side panel 117 is formed with a pierced or screen-like configuration to allow egress of air and lighten the overall weight of the collector 110.
In the depicted example embodiment, the mounting panel 111 extends vertically between the top panel 114 and the bottom panel 115, and horizontally between the side panel 117 and the rear panel 116. The mounting panel 111 is rotatably connected to the top panel 114 by at least one hinge 113 defining a hinge axis. The example embodiment utilizes three hinges 113, all of which are pin-and-barrel hinges, though other hinge configurations are contemplated. The axis of the hinge 113 extends generally parallel to an upper edge of the mounting panel 111. The mounting panel 111 is configured to be removably mounted to the mower M. A chute aperture 112 extends through the mounting panel 111 to allow a flow of air and mown grass from the collection chute C to the interior of the collector 110. The chute aperture 112 has a circumference and area at least as large as the circumference and area of the collection chute C of mower M to prevent grass buildup and blockage and allow free flow of discharged material.
In the depicted example embodiment, the top panel 114 is located above the bottom panel 115 and extends backwards at an upward angle relative to the bottom panel 115. At least one collector handle 118 may extend from the top panel 114 for an operator to grip to facilitate moving or installing the collector 110.
In the depicted example embodiment, the bottom panel 115 is approximately parallel to the ground and level with the deck of the mower M to ensure proper ground clearance. At least one collector handle 118 may extend from the bottom panel 115 for an operator to grip to facilitate moving or installing the collector 110.
In the depicted example embodiment, the rear panel 116 extends between the top panel 114 and the bottom panel 115, and horizontally between the mounting panel 111 and the side panel 117. In the example embodiment, the rear panel 116 is permanently connected to the top panel 114, bottom panel 115, and side panel 117. In certain embodiments, rear panel 116 is also connected to at least one of the top panel 114, bottom panel 115, and side panel 117 by at least one hinge 113. In certain embodiments, rear panel 116 is removably connected to at least one of the top panel 114, bottom panel 115, and side panel 117.
In the depicted example embodiment, the side panel 117 extends vertically between the top panel 114 and the bottom panel 115, and horizontally between the mounting panel 111 and the rear panel 116. In the example embodiment, the side panel 117 has an L-shaped configuration when observed from the top, with one leg opposite the rear panel 116 and the other leg opposite the mounting panel 111. In the example embodiment, the side panel 117 has a curved bend between legs. Other embodiments may be a single piece bent at an up to 90-degree angle or may be formed from a connection of two side panels 117 at for example a 90 degree angle.
The actuation assembly 120 couples the mower M and the collector 110. Actuator 121 is mounted extending between the mounting panel 111 and top panel 114, with an actuator control 122 mounted to the mower M within easy reach of an operator's position. An actuator line 123 extends between the actuator control 122 and the linear actuator 121 to transmit an actuation signal to either the linear actuator 121 or a power source 124 when the actuator control 122 is triggered. The power source 124 is operably connected to at least the linear actuator 121 to provide power to the linear actuator 121.
In the depicted example embodiment, the linear actuator 121 is an electric screw jack actuator; other embodiments may include for example other electric, pneumatic, or hydraulic actuators.
In the depicted example embodiment, the linear actuator 121 is mounted between the mounting panel 111 and top panel 114, with a first end mounted to the mounting panel 111 and a second end rotatably mounted to the top panel 114. When actuated, extension of the linear actuator 121 results in the combination of the top panel 114, bottom panel 115, rear panel 116, and side panel 117 rotating about the axis of the hinge 113. This creates an expanding gap separating the bottom panel 115, rear panel 116, and side panel 117 from the mounting panel 111. Grass contained in the interior volume of the collector 110 will then fall out through the gap by force of gravity. As the linear actuator 121 continues to extend, the combination of the top panel 114, bottom panel 115, rear panel 116, and side panel 117 continues to rotate until the gap is at least 30 degrees from vertical to ensure complete emptying. This may be of particular importance if the grass is wet. In certain embodiments, the angle of the gap may be larger, up to 180 degrees, to allow for more complete emptying or for the operator to inspect or manually clear the collector 110 if needed.
In the depicted example embodiment, the actuator control 122 is a rocker switch mounted to the mower handle H, allowing an operator to empty the collector 110 while remaining in control of the mower M; in other embodiments, the actuator control 122 is a button or other type of switch. In the depicted example embodiment, the actuator control 122 is a rocker switch having a neutral position and two opposing operation positions that operate linear actuator 121 in opposing directions. In the depicted example embodiment, the actuator control 122 is removably mounted; in other embodiments, the actuator control 122 is permanently mounted. In the example embodiment, the actuator control 122 is mounted via magnetic mount; in other embodiments, the actuator control 122 is mounted via interlock or anchor. In the example embodiment, triggering the actuator control 122 provides a signal to either the linear actuator 121 or the power source 124. The signal causes the power source 124 to provide power to the linear actuator 121 for extension or retraction.
In the depicted example embodiment, the power source 124 is a battery separate from any power system of the mower M. In other embodiments, the power source 124 is a part of the mower M, such as, but not limited to, the mower starting battery.
