Connecting

Rollomaximum may only be cou-
pled to the tractor's fixed drawbar,
where the towing eye (A) must fit
between the drawbar forks.
The towing pin (C) is inserted and
the support leg is hydraulically
raised to the maximum height off
the ground. (B)

Hydraulics

Rollomaximum XL 930/1240 requires the standard four double-acting and
single-acting hydraulic couplings, whereby the assignment and colour-coding
are as described in the table on the next page. One of the four double-acting
couplings is connected to an electrical valve block on the machine, which
supports a total of four double-acting functions on the machine. This valve
block is electrically controlled from the tractor's cab via a contact box (A) and
requires a 12 V supply (B). When the green lamp (C) lights up, it means that
the valve with the corresponding number is activated on the machine, when
the valve connected to the white hoses is activated in the tractor's cab. Only
one function can be actuated at a time.

Rollomaximum XL
 The towing pin can be secured with a split pin or similar.
 Note that hydraulic hoses and the support leg are mounted so that they
are not damaged by the tractor's lift arms and tyres when the tractor /
machine train is turned.
 Rollomaximum XL 930 / 1240 should never be hitched to a tractor
with a dead weight of less than 5 tonnes on the rear axle. This is
because the machine presses down on the tractor drawbar when
retracting and extending.
 Rollomaximum XL 930 / 1240 may only be hitched to a tractor via
a pick-up hitch as shown in the photo on this page. Never use a
ball hitch or the tractor lift arms. This is because the machine
presses down on the tractor drawbar when retracting and extend-
ing.
