4.3 Cam track adjustment
Rising and descending of the tines that are fitted on the tine arms is
ensured by the cam track. By adjusting this system, rise and descent
moments can be changed
*
.
Correct adjustment depends upon crop/terrain conditions and
forward speed. The cam track can be changed by placing the
adjustment strip (fig. 11) in one of the holes.
5 OPERATING THE HIBISCUS
®
• Make sure that nobody is near the machine at the moment
the PTO is engaged.
• Do not allow anyone to come within a 25 m radius from the
machine during work.
• Stop the tractor engine before leaving the tractor cab.
5.1 General directions
To enable turning on headlands, the rotors can be lifted
(approx. 25°) so that the rams are stopped by the abutments.
To achieve this: actuate the lift rams of the rotors.
- Lift the rotors up to the headland position.
- Engage the PTO at the lowest possible r.p.m. rate.
- Increase the motor speed.
- Drive forward.
Never drive the machine through the crop while the rotors are on
the ground without rotating, since this may cause damage to the
tines and tine arms.
- Lower the machine into the crop.
- Ensure the floating position of the hydraulic valve; the rams have
to telescope smoothly throughout the operation.
If the tractor spool valve does not have a floating position, keep
the valve in the position for lowering while you are driving, just
as long until the extremities of the ram are right in the centre of
the slotted holes.
The machine can be used for making swaths (fig. 12) and for moving
windrows across (fig. 13).
*. Cam track adjustment is only available on the Master
models of the HIBISCUS cam rakes
