Abstract

A reversible plough 6 is provided with a beam 6 which is rotatable in a member 7 attached to the three point linkage 14, 19 of a tractor and a rocker arm 23 is attached to the upper link 19 for rotating the plough beam by means of a rod 37, the rocker arm being held by means of a spring-urged cam 51 when the plough is working, the weight of the plough when it is raised causing the part 47 of the rocker arm to be disengaged to rotate the plough beam. In a modification the cam 51 is replaced by a pair of links connected to the part 47. Alternatively the pin 48 of the part 47 moves in a slot provided in a member which replaces the cam 51.
