Adjustable spacer for bottom arms of tractor three point linkage - consists of spreadable trapezium linkage with shanks fixed to bottom arms and including sprung extensible member

摘要

The adjustable spacer is for the bottom linkage of a three point linkage on a tractor. It consists of a spreadable trapezium linkage (, 8, 10), whose shanks (7) project beyond the trapezium. At their free ends, they are fixed with links (6) to the bottom linkages (2) at the three point suspension so that they can pivot in two dimensions. This trapezium linkage (7, 8, 10) is held a constant height by means of a holder fixed to the tractor.
