GEAR ENGAGEMENT
Mowers have a 7 speed gear box (4 forward
and 3 reverse).
These are selected with handle 7 and lever
10 (Fig. 2).
Use handle 7 to select the gears and handle
10 to select the travel direction, as indicated
in the label in Fig. 6.
N.B.: The engagement of the gears should
always be preceded by the disengagement
of the clutch.
Avoid a protracted clutch disengagement in
order to limit the wear of the thrust bearing.

PTO at 973 rpm - (profi le 20 x17 DIN 5482).
Use lever N° 8 (Fig. 2) to engage PTO of
Mowers 140-141.

to engage or disengage the PTO.
The PTO rotation is clockwise for all gear
directions.

The differential locking is obtained by means

N.B.: The locking device can be engaged whilst
motor cultivator is running, on condition that
wheels do not skid.
If so, disengage the clutch, engage the lock
and slowly release the clutch.

lock on a bend.
HANDLEBARS (Fig. 8)
Adjustment in height (vertical sense) allows 7
positions, obtained with lever N° 6.

UNLOCKING CUTTER BAR

Mowers are equipped with a Quickfi t that allows
an easy and quick coupling of implements.
