sliding or rotating. Depending on the rotation direction of the raking assembly, there are right
and left raking arms. The raking arms are fixed to the gearing transmission (1) and secured
with the aid of cotter pins (8). In the lower part of the raking assembly there is tridem axle
system, which guarantees proper raking on wavy surface. Rocker arms (2) with wheels (3)
are secured to the axle system wheel frame.
The height of raking arm setting above the surface is regulated by the adjustment screw (5)
and secured by the interlock.
The gear (1) cam mechanism applied enables the rotation of individual arms, due to which
the springtine fingers are lowered or raised according to current setting. During raking
springtine fingers are lowered almost vertically. The raked swath is retained by the forming
shield, due to which it is formed into an even windrow. In remaining instances the raking
springtines are raised to the upper position.
3.2.4 DRIVE TRANSMISSION
Torque is transmitted from the tractor PTO through a wide-angle PTO shaft (1) to the driving
shaft (2). Next, torque is transferred by PTO shaft with backstop clutch (3) to intersecting axis
gear (5). Torque is transferred from the intersecting axis gear to the raking assembly gears
(6) by two PTO shafts with overload protection clutch (4). The raking assembly gears rotate
in the direction indicated by arrows in figure (3.4).
ATTENTION
Do NOT use PTO rotation speed other than 540 rpm.
