Driving Up The Slope; Driving Down The Slope; Foot Brakes; Air Brakes Of Trailers And Articulated Trailers - Zetor FORTERRA HD Series Operator's Manual

Driving up the slope

Shift from higher to lower gear in time when
driving up the slope not to have a drop in engine
revolutions under 800 revolutions per minute, do not
allow a drive leading to the engine stop due to
overload.

Driving down the slope

Driving down the slope without engaged gear
speed is forbidden. If you travel from a longer slope,
shift the lower gear speed the steeper the slope is.
Shift the lower gear speed before the slope, if
possible.
Note: The gear speed with which you easily overcome an
ascent, you will also successfully manage descent.

Foot brakes

They are disc, wet, hydraulically controlled, double-
pedalled with automatic pressure equalizer.
When driving on the road, both pedals must be
connected by valve. Use disconnected pedals for
braking right or left wheel only when working in
terrain or on the field.
Note: When going down a steep slope with a trailer or
articulated trailer equipped with air or hydraulic brakes, it
is necessary to brake by a foot brake from the beginning
of descend.
When braking with one brake pedal trailer´s
brakes are not active!

Air brakes of trailers and articulated trailers

Air brakes of trailers (articulated trailers) control and
control of tractor brakes is done so that braking effect of
both vehicles is synchronized.
Working pressure is set by pressure regulator to 740 ± 20
kPa. When the pressure drops below 550 - 40 kPa by-
pass valves, puts auxiliary devices out of operation
(differential lock, engagement of front drive axle).
