2. Adjustments in working position
Rigid/floating working position.
The machine can operate in two ways:
Rigid position: (a)
The half-harrows are locked on the frame and work like
a rigid harrow: Improved soil levelling.
Floating position: (b)
The half-harrow outboard sides have a travel range of -
100 mm to approxi100 mm (-4’’/+4’’): The
floating position provides contour following on irregular
ground.
The machine is factory set in rigid position.
Setting to floating position:
- Remove roll pin (1) and washer (2).
- Check that the pin is not under load: If necessary,
activate transport/work cylinder control valves of the
half-harrows to free pin.
- Remove pin (3).
- Remove and rotate square spacers (4) through 90° to
bring the slot to a horizontal position.
- Reinstall pin (3).
- Reinstall washer (2) and roll pin (1).
- Repeat procedure on the second half-harrow.
The machine is in floating position.
Reverse the sequence to put the slot in vertical position
and the machine in rigid position.
Before placing the machine in working
position:
- Check that nobody is within the machine
pivoting area.
- If there is someone, make sure the
person moves away.
The two half-harrows must be in the same
working position.
