Automatic Engine Speed Preset Mode; Automatic Engine Speed Preset Mode For Operation In Field Mode - Zetor CRYSTAL HD 150 Operator's Manual

DRIVING OPERATION

Automatic engine speed preset mode

FHD18N060
The automatic engine speed preset mode is controled by pressing the button (1) on the control panel on the
right rear fender (A).
Turn on the automatic mode by pressing the button (1), it is signaled by the backlight of the button (1).
Press the (1) button again to deactivate, the button illumination (1) goes out.
The automatic engine speed preset mode operates in two modes, either in field mode or in stationary mode,
using the shaft in stationary mode.

Automatic engine speed preset mode for operation in field mode

The field mode works only at a tractor speed below 20 kph.
If the arms of the rear three-point suspension are in the upper position - the position set as OFF LIMIT (C) or
higher, the engine speed is set according to the speed stored in memory 1 (4).
If the arms of the rear three-point linkage are in the lower position - the position is set to ON LIMIT (C) or
lower and any external hydraulic circuit control (B) is moved to position (n), the motor speed is set according
to the speed stored in memory 2 (5).
If the arms of the rear three-point linkage are in the lower position - the position is set to ON LIMIT (C) or
lower and any external hydraulic circuit control (B) is moved to position (a) the engine speed is set according
to the speed stored in the memory 2 (5).
If the arms of the rear three-point linkage are in the lower position - the position is set to ON LIMIT (C) or
lower and any external hydraulic circuit control (B) is moved to position (b) the engine speed is set according
to the speed stored in the memory 2 (5), in case the external hydraulic circuit control (B) is set with time
unlimited flow.
If the arms of the rear three-point linkage are in the lower position - the position is set to ON LIMIT (C) or
lower and any external hydraulic circuit control (B) is moved to position (b) the engine speed is set according
to the speed stored in the memory 2 (5), in case the external hydraulic circuit control (B) is set with time
limited flow, the engine speed is set according to the speed stored in memory 1 (4) after the oil flow is ended.
If the arms of the rear three-point linkage are in the lower position - the position is set to ON LIMIT (C) or
lower and any hydraulic control circuit (B) is moved from position (b) to position (n), the motor speed is set
according to the speed stored in memory 1 (4).
For proper field operation, the limits of the rear three-point hitch (memory switching), both
engine speed and multiplier presets (for work and for rotation at the headland) must be properly set.
Depressing the clutch pedal or by pressing the clutch button on the shift lever or by activating the
brakes does not affect the memory switching function.
Recommendation:
This mode is suitable for field work, seedling, plowing, soil preparation, etc. (there is a reduction in the
amount of work at the headland where the machine itself adjusts the rotation as needed - at headland lower,
at work higher). For proper operation at work, it is necessary to set the desired speed in memory 2 higher
than the required speed for automatic multiplier shifting to a higher speed of multiplier. If you want the
multiplier automation not to set to a lower speed of multiplier (at the headland) then it is necessary to set the
speed in memory 1 higher than the speed for automatic shift to the lower speed of the multiplier. If you want
the multiplier automation to set the lowest speed of multiplier (at the headland), it is necessary to set the
speed in memory 1 lower than the speed for automatic shift to the lower speed of the multiplier.
