| description | A T-shaped scraper assembly is operatively connected to a drive unit via a cable assembly and is adapted to be pulled along the floor in one direction thus scraping manure or debris from the floor, and in the opposite direction to return the scraper assembly to the starting position. When moving in the non-scraping direction, means are provided to elevate the scraper blades slightly above the floor level. The scraper blades are floatably mounted vertically thus allowing them to follow the floor contours within limits and the width is adjustable within limits also. The drive unit includes a resilient or nonmetal main, grooved cable pulley and a resilient or nonmetal idler pulley situated at an angle so that the cable engaging around these pulleys runs relatively freely aligned in the cable grooves. The angling of the idler pulley relative to the main drive pulley reduces side friction between the cable and the grooves and between the cable portions where same cross one another. Means are provided to sense an obstruction and automatically shut off the mechanism. |
