Tractor-drawn spreader device - has trailer frame swivelling over support frame to discharge material selectively in any direction.

摘要

The trailer frame (1) fits on the support frame (2) so that it can be swivelled over the rotary axis of the spreader drums 180 deg. down to the other side. The drums have a smaller drum core (5'') which can be round or polygon-shaped and is fitted with equal-armed spreader skids (6) acting as compactors. The skids should be wider than 2 cm and have a radius of more than 2 cm. The trailer frame can be fixed so that it bends on the support frame infinitely selectively to the left, straight or right each by about 40 deg. by a hydraulic cylinder or telescopic tube. USE/ADVANTAGE - The material can be spread on a field left, right or both sides and in different proportions.
