OPERATING THE TRACTOR 40
C STALL GUARD
1. The "STALL GUARD" indicator lights up on the meter
panel, when:
2. The tractor gets overloaded and the engine rpm drops,
the tractor automatically slows down in response to
the load, which prevents an engine stall.
3. Using PTO driven implements and the tractor is in
"STALL GUARD" mode, the tractor speed will
automatically adjust with the loads on the engine.
C AUTO H-DS/STALL GUARD
1. The "STALL GUARD" and "AUTO H-DS" indicators
light up on the meter panel, when:
2. Setting the H-DS lever to the "UP" (Hi) position. Make
sure the " " (Hi) lamp lights up on the meter panel.
3. Using PTO driven implements and the tractor is in
"STALL GUARD" mode, the tractor speed will
automatically adjust with the loads on the engine.
4. The tractor gets overloaded and the engine rpm drops,
the tractor automatically slows down to the (Lo) low
speed range.
In this case, the "
" (Hi) lamp goes out and the " "
(Lo) lamp lights up instead.
5. The engine rpm has come up again, the tractor
automatically speeds up from the (Lo) low speed
range to the (Hi) high speed range. (The tractor speed
increases to match the speed control pedal.) If the load
is rather heavy and the engine rpm drops further,
"STALL GUARD" will still prevent engine stall.
A
When the H-DS lever is set at the "Lo" position, the
"AUTO H-DS" system does not work. (If the "
" (Lo)
lamp stays on and the "AUTO H-DS" lamp is flashing,
set the H-DS lever to the "Hi" position.)
A
Even in the "AUTO H-DS/STALL GUARD" mode, the
Hi-Lo speed change can be made with this lever.
Return the lever to the "Hi" position when there is no
more need to slow down.
A
When "STALL GUARD" is on and the PTO is engaged,
"STALL GUARD" switches to "STALL GUARD PLUS"
mode.
"STALL GUARD PLUS" maintains engine speed at a
higher rate.
C
MANUAL
When the "STALL GUARD" and "AUTO H-DS" indicators
go out on the meter panel, the unit is in manual mode.
In this mode, automatic control in response to the load
does not activate.
