12 Operators Manual
4. Adjustment/Operation
4.1 Preparing for operation
The Rake & Roll is normally delivered ready
for operation. In the event that the machine is
delivered part-assembled, do not attempt to
assemble or operate the machine before
consulting TILLSO.
4.1.1 Hitching to the tractor
Hitching to the machine when folded on its
parking stand is accomplished via a normal
tractor pick-up hitch operation. Ensure the
machine is on firm, level ground and reverse
the tractor to engage the hitch.
NOTE: if a tractor is used not
having a pick-up hitch, the
machine should be on- and off-
hitched unfolded in the work position to allow
use of the tilt cylinders to raise the drawbar.
Once hitched and the hook locked, the
hydraulic pipes can be connected. The pipes
are colour coded according to the cylinder
ports with similar colours. There are 2 main
circuits for the all machines:
RED
: Tilt (to raise for turning & return)
BLUE
: Fold (note used in conjunction with tilt)
A further circuit is present on the 12m
machine only:
GREEN
: Wing transport support on drawbar
Before activating the hydraulics, ensure the
tilt circuit taps are set as per below:
This setting should
always be
used
when folding, unfolding, or
parking the machine. Detailed
instructions on the use of this circuit follow in
section 4.3.2.
4.1.2 Transportation to field
Ensure the machine is correctly hitched to the
tractor, and all hydraulic lines are coupled
and locked (hydraulics in neutral or lock).
Ensure that secondary wing locks are fitted.
Ensure wheel nuts are correctly tightened
(see maintenance section).
Raise and lock the parking stand in its work
position. Ensure light boards are secured.
NOTE: maximum transport speed
for machines not fitted with brakes
is 25kph.
4.2 Preparing for work - unfolding
Ensure the machine is to be unfolded on firm,
level ground and the area for unfolding is
clear of any third parties.
Ensure the tilt circuit taps are set as the
preceding figure (section 4.1.1).
Remove any secondary wing locking devices,
and on 12m machines lower fully the
transport support arm.
Remove the light board and stow as
appropriate. Note this can be stowed on the
machine, or away from it if preferred to
