Abstract
A cart is configured to handle replaceable plates used on the blade of a plow or grader. The cart includes a wheeled frame and a plate holder configured to support the plate lengthwise in a generally upright orientation. The plate holder is supported on the frame by a parallelogram linkage that permits adjustment of the plate holder, and thereby the plate carried by the holder, without varying the orientation of these components. An inventive plate installation method is also disclosed. The method involves placing at least one plate on the height-adjustable plate holder carried on the mobile frame. The attachment holes defined in the plate are then aligned with the attachment holes defined in the blade.
Claims9
A method of installing replaceable, elongated plates on the blade of a plow or grader, said method comprising the steps of:
- (a) supporting at least one plate on a mobile cart, further including the step of placing the at least one plate on an angularly height adjustable plate holder of the cart;
- and
- (b) aligning attachment holes defined in the at least one plate with corresponding attachment holes in the blade, further including the step of angularly adjusting the height of the holder incrementally and thereby the height of the at least one plate incrementally.
