DRIVING WITH ENGAGED FRONT<br />
DRIVING AXLE<br />
Use the front driving axle with<br />
slipping of the rear wheels to increase<br />
the traction force of the<br />
tractor. It is permitted to engage<br />
the front driving axle on roads<br />
and hard surfaces up to 15 km/h<br />
(travel with engaged front driving<br />
axle causes increased wearing of<br />
front tyres).<br />
Permanent engagement of the front driving<br />
axle is permitted if there is a farming<br />
mechanism attached to the front suspension.<br />
This condition is mentioned in<br />
the instructions manual to the respective<br />
mechanism.<br />
Maximum permitted speed when driving<br />
with these attachments is 15km.h -1 .
