ATTENTION!
1. When reversing, NEVER engage the automatic FDA drive control mode; use the
forced drive only. Use the forced drive mode of the FDA for short-run jobs only: to
clear an obstacle or when running the tractor in reverse.
2. Be sure to disengage the FDA when on surfaced roads to avoid accelerated wear of
the front wheel tyres, drive parts and FDA.
Hydraulic Lift Linkage (HLL)
The HLL is intended for controlling and
operating the tractor aggregated with
mounted, semi-mounted and pull-type ag-
ricultural machines and implements at-
tached to the rear hitch linkage (RHL).
The hydraulic system is composed of con-
trols, an oil tank with filter, oil, pump, two-
or three-section flow-through distributor,
hydraulic power lift and power lift drive.
The operating controls of the hydraulic
system (7), (8) (Fig. E-29) are located in
the tractor cab, with the exception of the
pump engagement handle (the design is
left unchanged) and additional position
control handle (8а) ( Fig. E-29) located on
the rear of the tractor on the hydraulic
power lift.
Control of External Loads – these are
three handles of the flow-through distribu-
tor located on the right-hand side of the
steering wheel (the design is left un-
changed).
Positions of the handle (from bottom to
top) are: “Lift”, “Neutral”, “Drop” and
“Floating”.
