Working brakes
When driving on the road at transport
speed, both brakes pedals must be
locked together with a latch.
Steering control
Important! “MTZ” tractor is equipped
with hydrostatic steering system. If the
diesel engine is stopped, an oil pump,
which is put in action by the diesel en-
gine crankshaft, no longer feeds the
hydrostatic steering system. As a result
it automatically proceeds to a manual
mode which requires more effort to
steer the tractor while turning.
Stopping the tractor
To stop the tractor:
• reduce diesel engine crankshaft rpm;
• depress the clutch pedal;
• set the gear shift levers to a neutral
position;
• apply working brakes to stop the trac-
tor;
• apply the parking brake.
INPORTANT! To stop the tractor in an
emergency situation, simultaneously
press the clutch pedal and both inter-
locked brake pedals as quickly as poss-
ible.
Stopping the diesel engine
IMPORTANT! Before stopping the di-
esel engine, put an implement down to
the ground, and let the diesel engine
run at 1000 rpm for about 3...5 minutes.
It will allow decreasing the temperature
of the coolant fluid of the diesel engine.
To stop the diesel engine, proceed as fol-
lows:
• switch PTO off;
• put all distributor handles to a neutral
position;
• set the fuel feeding control lever to a
position that corresponds to the mini-
mum fuel position;
• pull diesel engine stop lever;
• turn a ground switch off (to avoid sto-
rage batteries discharging).
Power take-off shaft
IMPORTANT! To avoid shock loads on
the PTO, reduce diesel engine speed to
approximately 900 rpm when engaging
the PTO, then increase diesel engine
speed. Similarly, to reduce overstressing
the tractor PTO braking bands, reduce
PTO rpm at first by diesel engine speed
slowing down before disengaging the
PTO. It is particularly important for imple-
ments having a high moment of inertia.
These implements should always be fitted
with a free-running coupling.
There are two interchangeable PTO shaft
tails. When operating with a 6-splined
shaft tail, run the diesel engine at 2037
rpm to obtain standard PTO speed of 540
rpm.
When a 6-splined shaft tail is replaced
with a 21-splined one, switch PTO drive
to 1000 rpm and run the diesel engine at
2156 rpm to obtain standard PTO speed
of 1000 rpm
