5. PREPARATION AND SETUP
5-a. Operation Requirements
Requiring as little human effort as possible is
one of the most important premises for the
machine’s design, as well as attaining the best
possible comfort level for the operator.
To operate the equipment it is necessary to use
a tractor with a minimum of 90 HP. Of this
vehicle, both its 540 rpm power take-off (PTO)
and its oleo-hydraulic system are used, the
former for driving the grain augers and the latter
mainly for winding up the grain bag. This way,
the tractor’s traction system remains free, which
avoids an excessive wear of the clutch.
Hydraulic requirements: minimum flow 45
l/m, pressure 180 bares, hydraulic circuit
temperature: no higher than 70 °c
Special care must be taken not to use a tractor
with a power rating far greater than the
recommended figure, and the front wheels
should be plain, not studded. Pulling a heavier
tractor would cause excessive efforts on the
extractor’s structure and components.
Warning:
Maximum transport speed
30km/h (19 mph).
5-b. Position changes
The AKRON
EXG 400 X
mechanical grain
extractor can be set in two possible
configurations: an operating position and a
transport position. The transport position allows
the machine to be taken in tow by a pick-up or
tractor,
complying with the maximum
transportation width allowed.
Warning:
Do not travel on the machine
In the following figure, the main features of both
positions can be compared. It can be observed
that during transport position the lifting tube is
folded and the roll is practically parallel to the
chassis.

Instruction Action Obs.
Link the extractor to the
operating vehicle. Then,
connect the hydraulic circuit
together with the power take
off.
Once the machine has been
coupled to the tractor, place
the mechanical legs into
transport position.
