Engine and pump compartment

Hydraulic reservoir stop valve: easy and

quick interruption of the oil circuit between

hydraulic reservoir and hydraulic system

Easy access to air filter

Hydrostatic fan drive

The cooling system consists of two hydrostatically driven fans

Thermostatically regulated fan speed via engine oil and coolant temperature

Accelerated warm-up period

Fan only takes-off the needed power, reducing fuel consumption

All service points are

centrally integrated and

easily accessible via service

flap

All routine servicing work

possible from ground

Routine cleaning of the most

accessible coolers can easily

be performed by opening out

the individual cooling

elements
