Front power take-off
General information
The power take-off clutch is a multidisk, oil-bath and electro-hy-
draulic control type.
The front power take-off is directly linked to the crankshaft by
means of a flexing coupling; while the shaft-end is equipped by an
universal joint.
The oil used for P.T.O. operation is contained in the P.T.O. casing.
A specific gear pump installed on the P.T.O. shaft sucks the oil,
which flows first through a filter for being subsequently routed
under pressure to the clutch assembly through an electro-hy-
draulic distributor.
The oil is cooled in a special radiator ad is strained through a
second (15 micron) filter placed on the pressurized circuit located
between oil pump and hydraulic distributor.
A maximum 57 kgm (560 Nm) torque can be transitted to the
hitched implement in this way, i.e. 80 CV max. (or 58 kW). To avoid
these standards may be exceeded it is recommended that a
special joint having proper specifications be installed between
implement and P.T.O.
The P.T.O. shaft rear teminal has clockwise direction of rotation
(with respect to the driving position).
Control is electro-hydraulic type and is provided by the relevant
switching knob.
