Abstract
A scraper assembly and method for clearing manure deposits from a manure collection board associated with an animal cage arrangement is provided. The scraper assembly includes a first scraper blade extending in a generally diagonal direction with respect to a length of the collection board, but only partially across a width of the collection board, in an area of maximum manure deposits. The scraper assembly further includes a second scraper blade extending in a substantially opposite generally diagonal direction with respect to the diagonal extension of the first scraper blade. The second scraper blade, however, extends substantially across the entire width of the collection board. The first and second scraper blades are supported by a support frame capable of maintaining the generally diagonal opposite orientations of the two blades, and the support frame is driven by a driver which initially advances the scraper blades in a forward direction along the length of the collection board at which time the first scraper blade clears the area of maximum deposit on the board. The driver subsequently moves the support frame and the scraper blades in a reverse direction during which time th…
