# Improved work tool attachment for a work machine

## Abstract

A work machine extending in a fore-aft direction comprising a frame and a ground engaging mechanism, the ground-engaging mechanism configured to support the frame on a ground surface; a boom assembly coupled to the frame, the boom assembly having a pair of boom arms pivotally coupled to the frame; and an attachment coupled to a fore-section of the boom arms. The attachment may comprise a guide rigidly coupled to a fore-section of the frame; a movable member coupled to the guide, the movable member moveable relative to the frame by a pair of hydraulic cylinders, the guide restricting movement of the movable member in a non vertical direction; and a work tool coupled to the movable member wherein actuating the pair of hydraulic cylinders engages the movable member, vertically lifting or lowering the work tool relative to the frame. 18
