OPERATOR’S MANUAL
DOUBLE-ROTOR RAKES
DUO
Rakes DUO 640 and 740 are suitable for mounting on a tractor by means of tiller (1). Connect the
rake to tractor' links with pins (3) and protect with cotters (4) (Fig. 7).
Fig. 7. Mounting rake
As the rake is mounted on the tractor, examine the longitudinal balance and steerability of the
tractor-rake aggregate. To do this, calculate to formulas given in the appendix or weigh the set, and
then drive on the scales only with front axis of the tractor. If the pressure on the front axis is at least
20% of the whole set’s pressure, it means the set is stable. Otherwise, front axis should be balanced.
Due to the fact that rake DUO 740 is equipped with hydraulic rear swath curtain folding assembly it is
necessary to additionally connect machine's controller (1) (see Fig. 8) to tractor's lighter outlet (12V)
by means of plug (1) and a three-pin plug (3) to socket (4) on the rake's linkage. Fix the controller in
tractor's cabin by means of magnetic holder in a visible place. Controller ARDUO allows for switching
control from double-sided operation of the machine's rear star to cylinder for lifting and lowering the
rear swath curtain. Selected option is signalled with lighting up of the corresponding diode (6) found
under the option. To switch work mode push button (5) on controller until the corresponding diode (6)
is lit.

NOTE:
Failing to plug the controller to 12V supply or lack of supply while working will
disable hydraulic control of one of the cylinders –turning rear star or lifting rear
swath curtain.
5.2. Preparing rake for transport
NOTE!
Moving the machine from working position to transport position, and other way
round, should only be done on a level and firm ground. Before any operations
make sure that nearby the machine there are no unauthorized personnel
exposed to the risk of crushing.
In-line rake DUO 680 can be quickly switched to transport position what should result in width of
3 m. With raking arms dismounted and protective curtains folded it is possible to reduce it to 2.4 m. To
get the admissible rake DUO 740 width of 3 m at least partially dismount raking arms and fold back
prtoective curtains according to the below instructions.
In order to prepare the rake lifted on the tractor for transport - the following - should be done:
❑Set rear rotor so it is perfectly aligned with the front by means of turn cylinder,
❑(DUO 740) make sure that controller ARDUO is set to rear star turning mode Fig. 9),
