<p>A forage harvester is provided with a cutterhead frame (34), mounted on a support (40) which can be pivoted about a cylindric beam (80) at the top thereof. The cutterhead frame (34) can be pivoted about the axis (39) of the cutterhead (36) under the action of hydraulic cylinders (90). Lower feedrolls (26,27) are installed in a lower feeder frame (24), attached to the cutterhead frame (34), and upper feedrolls (20,21) are installed in an upper feeder frame (18), which can be tilted forwardly about a cylindric beam (67) attached to the front of the lower feeder frame (24). Means (61,62) for the coupling of a crop collecting apparatus (10) also serve to support the upper feeder frame (18), when the latter is separated from the lower feeder frame (24). Other means (96,95) enable the attachment of the upper feeder frame (18) to a tractor (110). Thus can be gained access for inspection and servicing between the upper (20,21) and lower feedrolls (26,27) and to the cutterhead (36). The support (40) can be secured to the cutterhead frame (34) in order to raise both together and gain access between the cutterhead (34) and the blower rotor (49). <IMAGE></p> |
