100 SECTION 21 - TRANSMISSION
Selecting neutral position
At power up, "Neutral and 2nd Gear" are automati-
cally selected regardless of the powershift lever po-
sition (1). The LED-2 and the LED-N are illuminated
in RED (neutral, 2nd) and the microprocessor is in a
neutral lock state. If, after driving, neutral is selected
and the shift lever stays in neutral for more than 3
seconds, the microprocessor automatically defaults
to the neutral lock state for safety reasons. In neutral
position, an automatic shift routine activates to pre-
vent damage to the transmission due to overspeed.
Neutral state
A feature of the powershift lever is the neutral lock
state, which does not allow forward or reverse direc-
tion drive to be selected. This feature prevents the
machine accidentally moving should the lever be
knocked into forward or reverse. To leave the neutral
lock state, you select drive direction followed by an
upshift by rotating the shift lever.
Selecting forward travel
To select forward travel push the lever away from
you and the "F" LED will illuminate green.
NOTE: when forward is selected you will not be giv-
en any indication of gear selected, only the maxi-
mum selected gear the transmission will shift too.
The microprocessor is programmed to be an auto-
matic gearshift system. In addition, if the forward
travel is now actually engaged, according to the sta-
tus of the machine (for example, if it is moving), the
microprocessor considers the road travel speed and
the travel direction before any gearshift takes place.
Selecting reverse travel
To select reverse travel pull the lever towards you
and the reverse "R" LED will illuminate orange.
NOTE: when reverse is selected you will not be giv-
en any indication of gear selected, only the maxi-
mum selected gear the transmission will shift too.
The microprocessor is programmed to be an auto-
matic gearshift system.
In addition, if the reverse travel is now actually en-
gaged, according to the status of the machine (for
example, if it is moving), the microprocessor consid-
ers the road travel speed and the travel direction.
