Abstract: An adzer skid assembly having a frame and a base plate attached to the frame. The base plate has an adzer unit attached thereto. The frame has a receptacle for slidably attaching the frame to a railroad track maintenance machine so that up and down motion of the railroad track maintenance machine does not produce up and down motion of the adzer skid assembly. Hydraulic cylinders are attached to the baseplate and are attached to skids, wherein the hydraulic cylinders raise and lower the skids relative to the frame and baseplate and determine the cutting depth of the adzer unit. During the adze cutting process the adzer unit is supported entirely by the skids as the skids move across railroad crossties.

Abstract: An adzer mount assembly having a slider box with a vertical slider and horizontal sliders. The vertical slider has an adzer which can be precisely positioned over a crosstie by hydraulic transverse movement of the slider box and vertical movement of the vertical slider. Because the horizontal sliders are mounted firmly to the frame of a railroad adzer machine the adzer is maintained firmly in a precise position over the crosstie during cutting, allowing precision planeing and surfacing of the crosstie.
