The linkage (1) has a rod (17) connected to a flange (23) by a selector (19) e.g. pin, where the linkage connects an upper hitch point (6) of a coupling device of an agricultural machine to an upper support point (9) of a tractor. An elastic device e.g. spring, is connected to a cylinder (16) by a bolt (21) and the flange. The agricultural machine is mounted via a three-point hitch during work and semi-mounted during transport.
