PTO shaft with clutch
The PTO shaft can be equipped with safety clutch to
protect the transmission components of the machine
from stress and/or excessive overloads.
The tilt of the PTO shaft must not exceed 10 degrees.
The clutch is already pre-adjusted for average stress. If
it slips too easily (and overheats), it will be necessary to
evenly tighten all the nuts (D) that retain the springs.
The clutch disks must be changed if the clutch still slips
after all the nuts have been tightened.
If the clutch does not slip, evenly unscrew all the spring
fixing nuts (D). Unscrew one turn at a time and check the
clutch after having worked about 300 meters. Repeat the
operation if necessary, remembering to unscrew one turn
at a time. If the clutch maintains a temperature of about
40-50 (104-122 °F) degrees during work, this means that
it has been correctly regulated.
IMPORTANT: Never fully tighten the nuts. This would
void the function of the springs and, subsequently, of
the clutch, thus damaging the transmission compo-
nents.
NOTE: This inspection must be performed at the
beginning of each new season.
