Abstract
1445623 Coupling implements to three point tractor linkage: coupling mowers to tractors P W ZWEEGERS 13 Aug 1973 [14 Aug 1972] 38307/73 Headings A1F and A1P An agricultural implement is coupled to the arms of a three point linkage 4, 5, of a tractor by means of an upwardly directed pin 1 and relatively short and long connecting arms 2, 3, which are pivoted to the three point linkage arms and fixed to the pin. The pin 1 has bearings 11, 12 which carry horizontal pivot pins which allow the implement, e.g. a mower, to be manually pivoted from an upward and rearwardly extending transport position to a sideways and upwardly extending position in readiness for lowering to the working position by the three point linkage. The arms 2, 3, are such that when the linkage is operated to lift the implement the pin 1 moves from a rearwardly inclined position, Fig. 2, to an upright position, Fig. 1, which allows safe manual pivoting of the implement from the raised, sidewards position since the weight of the implement does not act against the operator. Once the implement is raised the linkage 6-10 acts as a unitary rigid link. Two upper short arms 2 may be coupled to a single arm 4.
