Abstract:
A rollered grading assembly, including an elongated roller drum, an axle extending through the drum, an elongated housing partially enclosing the drum and connected to the axle, an elongated blade connected to the housing, a pivot rod perpendicular to the axle and connected to the housing, a coupler connected to the housing, and a pivot actuator connected to the coupler and housing. The coupler has a proximal end connected to the housing portion and positioned adjacent the roller drum and a spaced distal end extending away from the housing. Movement of the distal end a first distance while the proximal end remains stationary urges the housing to pivot around the drum and move the blade portion a second, shorter distance into a desired position relative grade.
Abstract:
A plow attachment for an excavator, including a distal portion having elongated curved front and rear walls, and an elongated top wall, a pair of oppositely disposed elongated hook-shaped side walls connected to the top, front and rear walls and defining an elongated trough, a soil-deflecting wedge portion extending from between the sidewall portions and positioned opposite the top wall member. The plow attachment includes a proximal portion connected to the distal portion and having a flat skid plate member, a structural member connected to the flat plate member, and a hoe connecting member connected to the structural member.
Abstract:
A method of operating a digging machine, including damping the response of a boom hydraulic cylinder operationally connected to a boom arm and actuating a bucket hydraulic cylinder operationally connected to a bucket.
Abstract:
An apparatus for controlling the depth of a hoe bucket, including a hoe bucket defining a cutting edge, an elongated member pivotably connected to the bucket, an actuator operationally connected to the elongated member, an electronic controller operationally connected to the actuator, and a position sensor operationally connected to the cutting edge and operationally connected to the electronic controller. The actuator may be energized to pivot the elongated member to a position adjacent the cutting edge for engaging ground, and positioning of the elongated member adjacent the cutting edge prevents the cutting edge from digging ground.
Abstract:
A system for digging sewer pipe trenches without the need of manholes, including a pair of oppositely disposed parallel elongated sidewalls defining a work volume therebetween, at least one support member extending between the sidewalls, and a location guidance assembly positionable within. The guidance assembly includes a pair of spaced parallel elongated positioning members, at least one elongated connection member extending between the positioning members, a GPS sensor operationally connected to each positioning member, a laser support member connected to one of the elongated positioning members, a mounting connection connected to the laser support member; and a laser connected to the laser support member. A movement actuator is coupled to the location guidance assembly, wherein energization of the actuator moves the laser between a first position and a second position in the working volume.

Abstract:
A kit for modifying a digging bucket for controlling the depth cut, including an elongated member operationally connectable to a hoe bucket defining a cutting edge, an actuator operationally connectable to the elongated member, an electronic controller operationally connectable to the actuator, and a position sensor operationally connectable to the cutting edge and operationally connectable to the electronic controller. The actuator may be energized to pivot the elongated member to a position adjacent the cutting edge for engaging ground. Positioning of the elongated member adjacent the cutting edge prevents the cutting edge from digging ground.
Abstract:
A screed assembly for attachment to the boom arm of a mechanical hoe, including a first elongated member, an elongated ground-engaging structural member extending therefrom, a hoe connection interface and a hydraulic boom connection interface on the first elongated member, and a blade-engaging assembly operationally connected to the first elongated member. An elongated blade portion is pivotably connected to the blade-engaging assembly, a first pivot actuator is operationally connected between the first generally elongated portion and to the blade-engaging assembly, and a second pivot actuator operationally connected to the blade-engaging assembly and the elongated blade portion. Energization of the first pivot actuator pivots the blade engaging assembly relative to the first elongated member and energization of the second pivot actuator pivots the blade relative to the blade-engaging assembly.
