Two-rotor in-line rake

DUO 740

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. 9
) to tractor's
lighter outlet (12V) by means of a plug (
1
) and a three-pin plug (
3
) to the 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 enables switching control between two-sided operation of the machine's rear
rotor and cylinder for lifting and lowering the rear swath curtain. The selected option is signaled
with the corresponding diode (
6
) under the option. To switch the work mode push button (
5
) on the
controller until the corresponding diode (
6
) is lit.

NOTE:
When the controller is not plugged to 12V supply or there is no supply while working
hydraulic control of one of the cylinders (turning rear rotor or lifting rear swath curtain) will
be disabled.

Preparing the 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 moved to transport position and thus the transport
width of
9' 10"
is obtained. With raking arms dismounted and protective curtains folded it is
possible to reduce it to
7' 10"
. To get the admissible rake
DUO 740
width of
9' 10"
at least
partially dismount raking arms and fold back the protective curtains according to the below
instructions.
