Engine Anti-Stall

This device avoids engine stalling if the power demanded by the transmission is higher than that supplied by the engine.
This can happen, for example, on steep hills in fields or on the road. In this case, the capacity of the transmission pump is
automatically reduced, which will significantly reduce the travel speed.
This function ensures that the engine speed will not fall below a defined threshold. This results in automatic reduction of
the travel speed.

Engine Overspeed

This function avoids the transmission making the engine accelerate beyond a maximum acceptable speed on braking
caused by the grip (hydrostatic braking). This results in slower deceleration of the machine, so that the engine speed does
not exceed a maximum acceptable value.

Hydraulic overheating

To preserve the life of the transmission, the hydraulic overheating system check that the
temperature in the transmission does not exceed a certain threshold temperature. If the
temperature of the oil exceeds this threshold, the travel speed decrease following a reduction
coefficient of the displacement of the pump.
When the temperature has lowered, the system return to the normal operation.
