Diff-Lock differential locking front/back
General Info
The Diff-Lock system is only suitable on ALPHA Evo EcoDrive versions 40 or 50 km/h. The controller drive a hydraulic valve ''
located between the front and rear hydraulic circuit. When the valve is controlled, the hydraulic circuit of each pump
becomes independent. Conversely when the valve is disabled, the flow of 2 pumps is uniformly distributed through the
circuit.
The differential lock Diff-lock is only engaged in FIELDS mode.
When the AUTOMOTIVE (Road) or PARKING mode is selected, the differential lock is automatically disengaged
The differential lock is automatically disengaged, when the travel speed is greater than 15 kph.

Anti-Skid (SAPE)
General info
The SAPE anti-skid system consists in supervising the number of revolutions of each one of the hydraulic motor, and if
necessary, limit the oil flow on the motor of which speed is higher than different (skating). The oil flow is thus distributed on
the motors of which the conditions of adherences make it possible to maintain the rate of advance of the motorized one.
To optimize the regulation in the turns, the controller is equipped with angular sensors placed on the front and rear axle of
the machine.
The anti-skid regulation is automatically suspended, but it remains active, when the travel speed is higher than 20 kph.
In the event of faulty operation of the system, the regulation is automatically disabled and an error message is displayed on
the screen.
