e) disconnect central pull rod 1 from bracket 3, connect it to the pillar on the frame of
agricultural machine (implement) and fix it with axle-pins.

1
– central pull rod; 2 – tightening screw; 3 – bracket; 4 – main lever; 5 – pin;
6
– vertical brace strut; 7 – lower links; 8 – platform for hydraulic hook
Having connected a mounted agricultural machine (implement) to the tractor at three points,
or a semi-mounted one at two points, perform preliminary installation of its frame into the hor-
izontal position. Perform installation by changing the length of vertical brace struts and cen-
tral pull rod.
When connecting mounted or semi-mounted agricultural machines and implements, the
length of vertical strut 6 (Fig.31) shall be minimum to ensure the maximum traffic clearance.
N o t e . Perform connection of the lower link and the central pull rod to coupling elements of
agricultural machine (implement) with the tractor parking brake being pulled up.
When disconnecting a machine or implement from tractor linkage mechanisms, disconnect
the central pull rod and fix it, then disconnect the lower links.
Linkage is adapted for hooking up with implements with the following categories of coupling:
–
NU-4 (cat. 4 ISO 730)
– main;
–
NU-3 (cat. 3 ISO 730)
– additional;
–
Kirovets
– additional.
The parameters of coupling dimensions of the linkage categories are given in Fig. 32 and in the table.
