5.10.1 General notes on auxiliary PTO's (code N16/N19)
Auxiliary power take-offs (N16 and N19) can only be engaged and
disengaged when the vehicle is stationary (electronic lock). The
PTO's can be used to drive hydraulic pumps (e.g. to drive cranes,
backhoes etc.), water pumps installed in fire trucks.(stationary op-
eration) generators etc. The hydraulic pumps etc. can be mounted
directly to the transmission housing (with code N16) or connected
via a drive shaft to the flange of the PTO output shaft (with code
N19).
The power flow to the transmission input shaft and therefore also to
the auxiliary PTO´s is interrupted when the clutch is engaged. In
case of use of the auxiliary PTO during driving, it is necessary to
stay in the previously selected gear. Shifting gear while the auxiliary
PTO is engaged is not possible as the drag torque of the driven im-
plement impedes synchronization in the transmission. Therefore,
gear shifting with the auxiliary PTO engaged is electronically dis-
abled.
