Control of engagement of the front
driving axle (MTZ 920/920.2/
920.3/952/952.2/952.3)
The control lever (1) has three fixed po-
sitions:
• “FDA OFF” – lowermost position.
Use it when driving on hard surface
roads to prevent the increased wear of
the tyres.
• “FDA forcedly ON” – uppermost po-
sition. Only use this mode in case of
incessant skidding of the rear wheels
and when moving backwards, when
the engagement of the FDA is re-
quired.
• “FDA automatically ON (OFF)” – mid
position. In this mode, the FDA is en-
gaged and disengaged automatically
by the free running coupling, depend-
ing on rear wheel skidding. Use this
mode during different field works.
ATTENTION! When using the tractor
without cardan shafts, put the control
lever (1) to the uppermost position
(“FDA forcedly ON”).
Hitch fixation mechanism control (2)
(for tractors with power governor)
Lever (2) has two positions:
• “Hitch unlocked” – rightmost position;
• “Hitch locked in upper position” – left-
most. To lock the hitch, lift the imple-
ment to uppermost position, having
put power governor arm (4) to position
«Lifting”, and turn handle (2) to the
left. Release down arm (4).
To unlock the hitch, lift the implement
and turn lever (2) to the right.
Control of lock of the hydraulic hook
(3)
The handle (3) has two positions:
• “Unlocked” – upper position;
• “Locked” – lower position.
To unlock the hydraulic hook, lift it with
arm (4) to upper position, pull handle (3)
up and fix it. To lock the hook after hitch-
ing the trailer to the tractor, lift the hook
with arm (4), release handle (3) from fix-
ation and move it to lowermost position.
