Disc rollers
We strongly recommend that you observe the safety warnings given
in the previous pages of this manual.
Secure the implement so as to prevent it falling or being lowered
accidentally.
Adjusting and
replacing the
scrapers
The disc roller is comprised of large diameter discs combined with a
series of shoes and blades mounted on an adjustable bar (43). The
bar can be adjusted for increments in the working depth of 25 mm.
Adjustment is obtained by altering the position of the upper arm (44)
that connects the bar to the frame of the roller.
Mounted on the arm there is a spring that presses the shoes against
the roller and the rear blades against the soil.
Adjusting the position of the blades and scrapers:
> Remove the locking pin securing the adjustment pin (45)
> Position the adjustment pin in accordance with the following indications:
•
Insert the pin in position (46) for heavy soil and rough ground: the
rear blades and the lower edges of the disc will be at the same
height.
•
Insert the pin in position (47) for medium heavy soil: the blades will
be positioned higher than the lower edges of the discs.
•
Insert the pin in position (48) for light soil: the blades will work by
gravity alone.
•
Insert the pin in position (49) to disengage the blades.
> Replace the locking pin to secure the adjustment pin.
Further blade adjustments may be made by way of the lock nuts (50).
As the blades become worn or to increase the spring pressure,
