ABSTRACT:
A variable width tool attachment for use with a vehicle is herein described as generally comprising a complete tool which is split vertically and in the direction of vehicle travel to form two half tools. The two half tools are slidably mounted for mutual relative movement in the direction normal to the direction of vehicle travel, i.e, in the direction of tool width. A hydraulic ram cylinder or the like is operable to move the two half tools to form the desired width.
In one form of the invention, a horizontal cutting header is provided with a chain cutter and a chain drive having at least one moveable idler sprocket to take-up and let-out chain in the width direction whenever the width of the tool is varied.
