two-rotor rake
Drawbar (
1
) enables mounting the rakes on 3-point linkage beam, which is part of each
tractor's equipment. Drive from tractor rpm is transmitted through intersecting axis gear (
2
) onto
rotary gear with shaft located on rake's front linkage (
16
). Rear rotor gear (
21
) is driven by gear (
2
),
roller located inside the linkage (
5
) and roller with homo-kinetic joint (
18
). Both rotors are
equipped with numerous raking arms (
8, 3
). Safety guards (
13
) reduce the risk of unwanted objects
getting into the area of rotor arms operating. The rake is equipped with adjustable swath guard both
on front and rear raking assembly (
20, 15
). Both assemblies are guided onto carts (
14, 19
).
