Abstract: A line guide assembly constrains the movement of working lines, such as hydraulic, pneumatic and electrical lines, that connect an implement attachment, such as a mulching head, to the main power and controls of a working vehicle, such as a skid steer loader. In one form, the line guide assembly has a mounting bracket for connecting to the mounting ear of the implement. An extension arm is coupled to the mounting bracket to accommodate articulation or other movement of the implement. A guide is connected to the extension arm, directly or via an additional cross-member. In one form, the guide defines a catch or loop that receives the working lines running to the implement. As the implement moves the extension arm pivots and the guide engages the working lines, which move through the guide opening, to constrain the working lines to a desired area between the loader and the implement.

Abstract: A rail grinder vehicle includes a series of connections between grinders and a chassis frame such that pairs of the grinders may be operated in an independent mode allowing separate movement and in wave control mode wherein the pair of grinders are coupled together for movement in unison. The grinders are supported from a K frame which is pivotably mounted at the center of the vehicle for stability. Each grinder is mounted upon a grinder support element and associated structure such that the grind stone of the grinder may be positioned relative to the rail and will automatically and simultaneously orient the grinding face of the grind stone at a proper angle relative to the rail corresponding to the desired position. A control system including a hydraulic system which is controlled by an electrical system is used to operate the grinders and maintain the individual grind motors at a constant power during grinding in an independent mode.
