23 CultiPress
Operating Instructions
soil ahead of the rings to fill low areas. The
sprung leaves crush clods as they pass
under the levelling board and align clods
with the front row of press rings.
The rear row of press roll rings are
intermeshed with the front row, overall ring
spacing across the machine is thereby
reduced to 115mm (4.5”). The action of
the second row of rings is to ensure that
large clods chopped by the front rings are
chopped a second time to reduce overall
clod size. The second row of rings are then
scraped by a set of rigid scrapers attached
to the rear gang beam.
The use of a CultiPress in tandem with a disc
cultivator can consolidate the straw / soil mix
through the soil profile, ensuring maximum
straw soil contact to increase the breakdown
process, minimise slug problems and leave
a firm weatherproof finish.
4. Adjustment / Operation
4.2 Rigid Tines
The leading tines are individually adjusted,
utilising eighteen different height settings and
three different rake settings. Added security
of shear bolt protection ensures trouble free
operation in tough, arduous conditions.
The ability to effectively eradicate tractor
wheelings without moving dry clods onto
the wheelings is most important for even
germination.
4.3 Pro-Active (Sprung)
Tines
The Pro-Active tines are designed to move
soil and shatter clods to a greater degree
than traditional rigid leading tines. The
ability to move in all directions (upwards and
sideways) allows them to clear stones and
other obstructions. They feature simple,
pinned tine depth adjustment for easy depth
variation.
