Tractor drawn plough - shares pivoted by operating arm to adjust angle and alter distance between furrows

摘要

A tractor drawn plough has multiple shares which can be adjusted to alter the distance between furrows. These remain parallel to each other and any regulating can be done during use. The main frame (15) carries separate plough-shares (17) which pivot about vertical axes on the frame. An operating bar (19) runs parallel to the main frame and the shares also swing about pivots (18) in this main frame. A linkage (42, 43, 79) is used to adjust the angle of the shares and is operated from the tractor driving seat. The rear end (27) of the attachment is supported by wheels (28, 90) which have adjustable tracks.
