Abstract: A snowmobile ice scratcher has a wire form in the shape of a hook secured to a track frame of the snowmobile. The wire form has a coil portion at the track frame and a downwardly extending leg portion that in an undeflected position has an elongate snow/ice spray generating portion configured as a flattened wire segment portion oriented downwardly, forwardly, and inwardly for generating snow/ice spray on hard packed snow and/or ice surfaces. An upwardly facing flat surface of the elongate snow/ice spray generating portion faces upwardly, inwardly, and forwardly and creates an ice/snow spray as the snowmobile is moving forward that is primarily directed inwardly to provide improved lubrication of the track assembly and improved deposition of ice/snow spray under the tunnel on a heat exchanger, thereby providing improved cooling of the snowmobile engine. The hook shape of the leg portion allows rearward operation of the snowmobile without damage to the ice scratcher.

Abstract: Disclosed are excavators or other power machines having a lift arm structure with a bucket coupled to an arm to pick up material during a digging or scooping operation, and a bucket cleanout devices to aid in removal of material from the bucket. The bucket cleanout devices include components which are rotatably coupled to a support structure, such as the arm, an implement carrier and/or the bucket and configured to aid in removal of material during a material dumping movement of the bucket.
