Abstract
Apparatus and method for material distribution, including a drawbar to which is fixedly connected a bucket body. Wheels are attached to the drawbar on opposite sides of the bucket body between an open side and a gate thereof. A lower edge of the open side of the bucket body, which can receive material, is in the form of a cutting blade or teeth. The gate, which is disposed opposite from the open side, can be opened and closed. At least part of a top side of the bucket body forms a platform for an operator. At least one engine is provided and is drivingly connected to the wheels. A handlebar is connected to the bucket body, forward of the platform, for pivoting the bucket body about the wheels so that the cutting blade or teeth can be brought into or out of contact with a surface.
Claims14
An apparatus comprising:
- a drawbar (70);
- a bucket body (12) fixedly connected to said drawbar (70), wherein said bucket body (12) is open on one side for receiving material, further wherein a lower edge of said bucket body (12), at said one open side, is in the form of a cutting blade (78) or teeth, further wherein a side of said bucket body (12) opposite the one open side is provided with a gate (61) that is configured to be opened or closed to release material from, or retain material in, said bucket body;
- an operator platform formed by at least a part of a top side of said bucket body (12), said operator platform configured to receive feet of an operator and to support the operator positioned in a standing position thereon;
- wheels or endless tracks attached to said drawbar (70) and disposed on opposite sides of said bucket body (12) between said one open side and said gate (61) of said bucket body;
- at least one engine (14;
- 202, 203) disposed on said drawbar (70) or said bucket body (12) and drivingly connected to said wheels;
- and
- a handlebar (64) non-pivotably connected to said bucket body (12), forward of said operator platform (77), for pivoting said bucket body (12) about said wheels such that said cutting blade (78) or teeth can be brought into or out of contact with a surface to be worked upon, said cutting blade (78) or teeth being brought into contact with said surface with application of a downward force on said cutting blade (78) or teeth, wherein said downward force applied on the cutting blade (78) or teeth is applied both by a proportionate machine weight applied by tilting the bucket body forward to bring the cutting blade (78) or teeth into contact with the surface and a weight of the operator, wherein the weight of the operator is applied to the wheels or endless tracks for increased traction, and proportionately to the cutting blade (78) or teeth, depending upon where on the operator platform the feet of the operator are placed and how the weight of the operator is distributed on the feet of the operator.

- an operator platform formed by at least a part of a top side of said bucket body (12), said operator platform configured to receive feet of an operator and to support the operator positioned in a standing position thereon;
- wheels or endless tracks attached to said drawbar (70) and disposed on opposite sides of said bucket body (12) between said one open side and said gate (61) of said bucket body;
- at least one engine (14;
- 202, 203) disposed on said drawbar (70) or said bucket body (12) and drivingly connected to said wheels;
- and
- a handlebar (64) non-pivotably connected to said bucket body (12), forward of said platform (77), for pivoting said bucket body (12) about said wheels such that said cutting blade (78) or teeth can be brought into or out of contact with a surface to be worked upon, wherein said cutting blade (78) or teeth are brought into contact with the surface with application of a downward force on said cutting blade (78) or teeth, wherein said downward force applied on the cutting blade (78) or teeth is applied both by a proportionate machine weight applied by tilting the bucket body forward to bring the cutting blade (78) or teeth into contact with the ground and a weight of the operator, wherein said weight of the operator is variable depending on positioning of feet of the operator on said operator platform;
- at least one ground engagement attachment (46) removably disposed on said drawbar (70) or said bucket body (12) and configured to be brought into and out of engagement with the surface, wherein said at least one ground engagement attachment is a grading moldboard (46) disposed on said drawbar (70) remote from said one open side of said bucket body (12), and wherein said grading moldboard (46) is pivotable in planes that range from substantially parallel to the surface to substantially perpendicular to the surface,
- wherein said grading moldboard (46) comprises a composite torsional beam skeleton having at least three thin-walled tubing sections defining moldboard upper, lower, and center torsional members, all held in position by at least three vertical support members and being reinforced on opposite ends by at least one diagonal support strut, and wherein said grading moldboard is provided with a cutting edge disposed along one side, adjoined by gage sheet metal shaped into a curve in one axis.
