3.17.3 Arm

The arm consists of a screw with a joint 1, a tube 2, a yoke 3, a forelock 4, a pin 5, a
washer 6, lock nuts 7 (figure 3.17.3).
The adjustment of the arm length is carried out in the following order:
- turn the lock nut 7 off;
- change the arm length by turning the tube 2 clockwise or contraclockwise;
- as the arm length is adjusted, lock the screw connection with the lock nut 7.
The arm is adjusted in the following way:
- when the tractor operates with all mounted and semi-mounted agricultural ma-
chines and implements (except for wide-cut), the RLL links shall not freely move in vertical
direction in the arm yokes; For this reason the arm pin 5 shall be mounted into one of the
holes of the yoke 3. The pins 5 shall be equally mounted on the right and on the left arms;
- as the tractor operates with wide-cut mounted and semi-mounted agricultural ma-
chines it is required to mount the pins 5 in the grooves (slots) "A" of the arm yokes 3 to ensure
vertical displacement of the links with respect to the arm yoke.
