The live PTO is engaged by using the
dual clutch. Depressing the clutch pedal
through the first stage disconnects the
drive from the engine to the transmission
without interrupting the operation of the
PTO.

Power Take-Off (PTO)
Warning
Power take—off shafts and power
take—off driven implements can be
extremely dangerous, observe the
following important points:
* DO NOT operate the tractor without
a PTO cap fitted. It protects people
from injury as well as the splines
from damage.
* Before attaching, adjusting or work-
ing on PTO driven implements, dis-
engage the PTO, stop the engine and
remove the key.
* DO NOT work under raised equip-
ment.
* Before engaging a PTO driven im-
plement and after fitting, ALWAYS
carefully raise and lower the imple-
ment using Position Control, and
check clearances, PTO shaft slide
range and articulation.
* Ensure that all PTO driven imple-
ments have the correct guards, are
in good condition and conform to
current standards.

There are two types of Power Take-
Off (PTO) available, Live Drive from the
engine using a dual clutch and mechani-
cal engagement (ITM475 and ITM 485).
The second type is an Independent Power
Take-Off (IPTO) using a single split torque
clutch and hydraulic engagement (In other
tractors of ITMCO.).
The PTO shaft (1 Fig. 4) at the rear of
the tractor has six splines and a diameter
of 35 mm (1 3/8 in) with an annular groove
for positive fixing of implement couplings.
A removable cap (2) protects the splines
and the operator when the shaft is not in
use.
