Abstract

See full text

The invention relates to agricultural machines and is particularly applicable to tractor mounted drum mowers which suffer from the problem of tilting about the ground engaging point nearest to the tractor when undergoing right-hand turns. This problem is met by the provision of a machine having a mounting beam, a main beam supporting in a depending fashion one or more working units and at least three links for floatingly coupling the main beam to the mounting beam, at least one of the links being coupled to the main beam at a location below the latter. This provides a stable machine and in order to obtain independent flotation of the working units when more than one is employed, the links are coupled to the respective beams by universal joints with the exception of one link which is coupled to the mounting beam by a non-universal pivot in order to prevent a transverse shift of the working units during flotation.
