Abstract
The present invention provides a grading boot attachment which when attached to a roadway grading moldboard allows for more accurate and uniform grade cutting or leveling with the moldboard. The attachment includes amounting plate for mounting to the moldboard, a winged section and an adjustable leveling gate which may be adjusted to the appropriate angular position for any desired task. A compressive strut retains the leveling gate in an operable position.

A grader moldboard boot attachment adapted for mounting onto to a grading end of a grader moldboard carried by a motor grader and operational use in a controlled flow of graded material along a grading end of a the grader moldboard, said grader moldboard boot attachment consisting essentially of a mounting plate equipped to mount the attachment onto the grading end of the grader moldboard, a fixed winged section for moving graded material along a grading plane in substantial alignment with a grading edge of the grader moldboard with said fixed winged section extending outwardly at an obtuse angular disposition from the mounting plate so as to outwardly extend the grading end of the moldboard, an adjustable grading and leveling gate pivotally mounted to the fixed winged section, an adjustable gate retaining member for adjusting the adjustable gate to a desired open gate position while also allowing the gate to move towards a closed position and a gate restraining member operationally connected to said adjustable gate so as to apply an outwardly biasing force against said gate and maintain the adjustable gate at a desired operational grading and leveling position.
A combination of a motor grader equipped with a grading moldboard and a grading boot attachment attached to the grading moldboard, said grader moldboard boot attachment comprising a mounting plate mounted to the grading moldboard of the motor grader, a fixed winged section extending obtusely outwardly from the mounting plate for moving graded material along a grading plane in substantial alignment with a grading edge of the grading moldboard, an adjustable grading and leveling gate pivotally mounted to the fixed wing for grading and leveling the graded material, an adjustable retaining member for adjusting the adjustable gate to a desired grading and leveling gate position while allowing the gate to move towards a closed position and a gate restraining member operationally connected to the adjustable gate so as to apply an outwardly biasing force against said gate.
A method of grading a roadbed base to a desired grade with a motor grader equipped with a grading moldboard and a mounted grading attachment comprised of a mounting plate mounted onto one end of the moldboard, a fixed grading winged section extending outwardly from the mounting plate at an obtuse angular disposition to the moldboard, an adjustable grading and leveling gate, an adjustable retaining member for adjusting the gate to a desired grading gate position while allowing the gate to move to a more closed gate position and a gate restraining member operationally connected to the gate so as to apply a desired outwardly biasing force against said gate, said method comprising:
- a) ascertaining the desired gate position of the adjustable gate for the grading of the roadbed base;
- b) adjusting the gate of the grading attachment to the desired gate position;
- and
- c) grading the roadbed base to a desired roadbed base grade by manipulating the moldboard and the mounted attachment so as to grade and level the roadbed base of the desired grade.
