1-13. (canceled)
Feeding apparatus for a harvester, comprising:
- opposing arms, with operating devices, pivoted to a frame, for creating transverse compression,
- two opposing feed rollers installed in the arms as the only feed rollers for feeding a tree through a throat,
- two sets of two hydraulic motors, each set of the two hydraulic motors driving each feed roller, thus creating a mechanical connection between the hydraulic motors of each feed roller, and
- two parallel pressure-medium lines operating the hydraulic motors, and in each pressure medium line having two hydraulic motors in series, each motor of two being one motor of the opposite feed rollers, the two sets of two hydraulic motors connected in the opposite order in said two pressure-medium lines.
1 more element
Feeding apparatus, according to claim 1, wherein each feed roller includes its own auxiliary frame and the bearings carrying the feed roller, as well as two hydraulic motors rotating the feed roller, attached to the auxiliary frame.
A harvester, which includes:
- a frame with suspension devices, being in the longitudinal direction of the frame,
- stripping blades pivoted to the frame, with operating devices, for compressing the stripping blades transversely in order to form a throat, characterized in that it includes a feeding apparatus according to claim 1.
