7.6 Safety Device
The dimension A must always be higher than 85 mm (3-11/32”) or there could be the danger
of NOT unhooking when it receives blows that are too strong
Safety device B unhooks when it receives blows that
are too strong for the machine structure. The
dimension A is the length of the rubber spring of
safety device when tensioned between the two
washers. It is 95 mm (3-47/64”) for the standard
adjustment. When adjust the length of the spring,
tighten the relevant screw very carefully until
unhooking occurs at reasonable intervals only.
8. DRIVELINE ATTACHMENT
8.1 Adjusting Shaft Length
In order to make sure that the driveline is the right length compared with the tractor power takeoff (with the
mower already attached to the tractor), proceed as follows:
1. Remove the two joint axle shafts and insert
them separately on the two power take-offs
(tractor and mower) with the clutch on the side
of the mower.
2. Place the two axle shafts one alongside the
other.
3. Check that when the driveshaft is stretched to
its minimum length (repeatedly raise and lower
the machine to find this position), the tubes do
not touch the bottom, so that there is always a
minimum clearance “B” of 20 mm (0.79 inches).
4. If necessary, reduce the two axle shafts as well
as the two axle shaft shields by the same
amount (keeping the above mentioned
conditions), and take care to clean and lubricate
them before starting work.
5. Use the relevant chains to fasten the outer
driveshaft shields.
NOTE:
When the driveshaft is stretched to it’s maximum length (with the safety device released), the tubes
must remain inserted at least 10 cm (4 inches).
Failure to make these adjustments prior to operating the cutter could result in premature IID
shaft failure.
NEVER OPERATE THE MOWER WITH THE SHIELDS OR GUARDS REMOVED. DO
NOT APPROACH ROTATING SHAFTS WHEN IN OPERATION.
