Interrupted Sound Signal; Dead Start Of The Tractor - Zetor FORTERRA HSX 120 Operator's Manual

DRIVING OPERATION

Interrupted sound signal

PHS18N052
If the tractor speed is regulated by partial released clutch pedal at higher engine revolutions than
1,200 rpm, an interrupted audio signal is generated and a warning on the display of the instrument
panel is shown. If this situation occurs, immediately fully pres the clutch pedal to the end or release
the clutch pedal to its upper position and wait until the acoustic signal is deactivated. Decrease
engine revolutions below 1,200 rpm and then continue in operation with the tractor. If you do not do
this, after 8 seconds the interrupted acoustic indication changes to uninterrupted indication.

Dead start of the tractor

If at dead start, engine revolutions are higher than 1400 rpm L gear of multiplier is automatically shifted, not
depending on the switch of multiplier pre-selection on dashboard being on or off. If the multiplier pre-
selection switch on the dashboard is on at dead start, L gear of multiplier is shifted automatically
independent on the number of engine revolutions at dead start (i.e. when the engine revolutions are lower
than 1400 rpm).
A very fast dead start can cause overloading of driving gear, increased fuel consumption,
st
excessive wear of tyres and damage to load. Use dead start on the 1 gear only when driving with
heavy trailer to the slope and in difficult terrain.
