Operating Instructions
4. Adjustment / Operation
leaves crush clods as they pass under the
levelling board and align clods with the front
row of press rings.
The levelling boards are hydraulically
controlled for height with contour following and
board pressure maintained by means of a
pair of accumulators. The hydraulic cylinders
on each levelling board are a matched
master and slave pair for parallel travel.
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 the CultiPress in tandem with a
disc harrow for straw incorporation, is to
consolidate the straw soil mix through the soil
profile ensuring maximum straw soil contact
to increase the breakdown process, minimise
slug problems and to leave a firm
weatherproof finish.
