发明名称 Closing mechanism for a fine material pan on a manure spreader
摘要 A device for automatically closing the fine material pan on a manure spreader is disclosed wherein, after being released to a clean-out position, the motion of the fluid endgate is utilized to return the fine material pan to its normal operating position. A lost motion linkage connects the fine material pan to the arm of the fluid endgate. A retraction of the fluid endgate to a transport position through manipulation of a tractor's hydraulic system effects a closing of the fine material pan without the operator having to dismount the tractor.
