3.4
The transmission gearing (2) has 9 radiating shafts, to which are secured raking arms (3).
Each of the arms is equipped with 3 springtine fingers for raking the swath. They are
mounted on the arm extension with the aid of securing angles (6), which prevent fingers from
sliding or rotating. Arms are secured to the gearing transmission with the aid of linchpins (7).
Rake suspension is connected in the lower part of the transmission gearing. The
undercarriage legs (9) together with the wheels (10) are secured to the wheel beams (8). The
extension arm (11) together with the forming shield (12) secured to it is on the left side of the
windrower. During machine work the shield constitutes a barrier for the raked swath, due to
which it is not scattered but formed into a regular windrow. The extension arm is secured by
the left shield wing strut (13) and locked with a linchpin. The height of raking arm setting
above the surface is regulated by the regulation screw (16) and secured by the interlock (17).
3.3 HITCHING SYSTEM
The windrower rake carousel is mounted on the tractor using the hitching system integrated
in the support frame of the machine. Figure ( 3.2A ), shows detailed mounting structure.

categories, designed for securing the upper suspension point irrespective of three-point
linkage category. The upper pin may be placed in one of two available sockets. The upper
socket (A) with an elongated shape, it is used during machine work (working position), socket
(B) for transporting the windrower.
