5.5 DD Light Roll
The spacers and rings on the DD Light Roll
are held under tension by the end plates at
the outer ends of the roll tube.
Specialist equipment is required
for the disassembly of DD Light
rollers. Please consult your
dealer under any circumstances
that require disassembly of these
axles.
Maintenance of these rollers is limited
to yearly/end of season greasing of the
bearings and regular inspection to ensure
the assemblies are tight, and scrapers are
correctly set.
The scraper is intended to clear dirt
from blocking between adjacent DD
rings. If adjustment to the scrapers
is required ensure that the scraper
cannot contact the spacer even
under load. Regularly inspect the
spacers for signs of wear and adjust
any scrapers to ensure no contact
can be made.
5.6 Brakes & Wheel Hubs
The brakes should be tested before using for
the first time and after the first laden journey.
Check that the road and parking
brakes operate and release
correctly before using the
machine.
Check for hydraulic fluid and air
leaks.
Brake and hub maintenance and
servicing should be carried out by
an authorised Great Plains dealer.
5.7 Hydraulics
A low oil flow should be used,
i.e., tractor tickover or low flow
selected.
The wing circuit is controlled by an
overcentre valve contained within
the manifold block which positively
locks oil flow until pressurised by
the tractor. System pressure can
be retained in the circuit even
after depressurisation of the
tractor quick release couplings.
Exercise extreme care when
checking the valve or circuits, and
under no circumstances attempt
to adjust or loosen fittings without
prior reference to your authorised
dealer, and detailed maintenance
instructions.
The hydraulic circuit contains
specialised fittings which should
not be tampered with under any
circumstances. Do not attempt
to modify hose routings or hose
clamping arrangements, doing so
may cause serious damage to the
machine and/or injury.
5.8 Preparation for
Storage
If you need to store the machine for a longer
period, observe the following points:
• Park the machine undercover if possible.
• Protect the roll / discs against rust. If you
need to spray the implements with oil, use
light biologically degradable oils, e.g. rape
oil.
Cover any rubber sections before
using oil sprays. These sections
must not be oiled. Remove
any traces of oil with a suitable
cleaning agent.
