37 OPERATING THE TRACTOR
B HST Mode Select Switch
Every time this switch is pushed, "MANUAL", "STALL
GUARD" and "AUTO H-DS/STALL GUARD" are selected
consecutively. Choose the best mode according to the
type of job or your operating style. The selected mode is
displayed on the indicator on the meter panel.
C
STALL GUARD
1. Push the HST mode select switch until the "STALL
GUARD" indicator lights up on the meter panel.
2. If the tractor gets overloaded and the engine rpm
drops, the tractor automatically slows down in
response to the load, which prevents an engine stall.
C
AUTO H-DS/STALL GUARD
1. Push the HST mode select switch until the "STALL
GUARD" and "AUTO H-DS" indicators light up on the
meter panel.
2. Set the H-DS lever to the "UP" (Hi) position. Make sure
the " " (Hi) lamp lights up on the meter panel.
3. If 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.
4. When 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 up 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.
C
MANUAL
Push the HST mode select switch until the "STALL
GUARD" and "AUTO H-DS" indicators go out on the
meter panel. This provides for manual mode.
In this mode, any automatic control in response to the load
does not activate.
