Transmission programming
6. Turboclutch operation
The turboclutch function is simulated by modulating the working pressure in the hydrostatic circuit as a
function of the engine speed. By reducing the pressure in the hydrostatic circuit, the tractive power is
reduced at low engine speeds. The effect of the turboclutch function, therefore, is comparable to
measured actuation of the clutch pedal.
If the engine speed falls below 1400 rpm, the working pressure in the hydrostatic circuit is steadily
reduced with decreasing engine speed. In this way the engine load is reduced, as in a real turboclutch,
and the engine is prevented from stalling.

Turboclutch operation is automatically reactivated after every restart.
