Abstract
A forage harvester comprises a rotatable cutterhead (36), operable to comminute crop material and to deliver the same to a blower assembly (48, 49), which propels the material upwardly into a duct (52), which in turn directs it into a collecting vehicle, which is moved aside or behind the harvester. The blower assembly (48, 49) includes a rotatable blower (49) and a housing (48), which is attached to a support frame (60), affixed to the main frame (1) by three bolts (67, 65) only. The duct (52) is mounted onto a base plate (78), which is not connected to the blower (48, 49), and can be rotated at a variable speed with respect to the main frame (1). A set of pull rods (68) and studs (70) permit easy and precise adjustment of the rotor (49) to the housing (48). This arrangement prevents the deformation of the blower housing (48), during and after its assembly to the harvester, and eliminates the need for subsequent readjustment of the blower (49) to the housing (48), in order to restore the blower efficiency.
