Independent Flotation and 5 Pivot Points
Centre pivoting on the two wing sections, two folding pivots and the pivoting
drawbar eye allow individual sections to follow the contours. Add
to this the floating inner links which join the wing sections to the
centre rolls section allowing all three sections to float completely
independently and you have
the best possible contour
The Grass Roller's hydraulic
folding system is linked
into two accumulators
and a hydraulic pressure
gauge. The gauge allows
the operator to set the
amount of weight transfer from the central section to the wings, dependant on ground conditions and how
much water ballast is in the Roller sections.
Rolls without a weight transfer system tend to exert the highest ground
pressure in the centre as the chassis of the rolls, drawbar and wheels are
the middle roll section.
Even with a basic sprung weight transfer system the hinges at the end of
centre roller section negate much of the transfer effect.
FREE FLOATING ROLLER SECTIONS - HE-VA Rolls have free floating roller sections
and the SAT weight transfer system which uses hydraulic accumulators and a setting
gauge to allow the operator to redistribute additional frame weight from the centre
section to the wings ensuring even weight distribution across the full width of the rolls!
The weight of the Grass Roller can be increased by over 70% by filling
the Roller Tubes with water as ballast if required, this provides for very
effective consolidation on spring grassland or before reseeding cultivated
HE-VA's clever folding system allows the
operator to fold or unfold the Grass Roller
from the tractor seat in seconds using only
two spool valves, when folded the wings
are effectively locked automatically for road
The standard Grass Roller provides effective consolidation for existing grassland or
cultivated land ready for seeding, add the optional Levelling board and tines and you have
a useful scarifier and light cultivator. For the complete solution, a seeder mounting bracket
and air seeder can be mounted onto the Grass Roller giving you the option to reseed or
overseed grassland, undersow crops and apply other small seeds where required.
The new HE-VA Farmers Grass Roller has a working width of 6.3m (20ft) and incorporates
HE-VA's tried and tested Special Active Transfer (SAT) weight distribution system. This ensures even
pressure accross the working width when rolling. A three section tip folding design allows each
section to float independantly, while centre pivots on each section ensure ground contors are
The ability to water ballast the Grass Roller significantly increases the machines working weight
and yet large bearings and a 600mm diameter roller ensure it is relatively easy to pull. The
chamfered edges on each roll section also ensure that there is no damage done to the grass
surface by scrubbing when turning on the headlands.
The Farmers Grass Roller is a simpler version of the Contractors Grass Roller which was launched 3
years ago but is not available with the accessories for seeding and
scarifying the grass.
The Electronic version of the OPICO Air 8 seeder suitable
for mounting on a 6.3m Grass Roller and capable of seedrates which would allow over
seeding or light reseeding. The landwheel on these machines gives a constant application
rate even when the speed that the Grass Roller is being used at varies with the terrain.
The OPICO Air 16 Seeder is suitable for either the 6.3m or 8.2m Grass Roller and for
overseeding or reseeding applications at higher seed rates and higher forward speeds.
Suitable for contractors and high output work the Air 16 maximises the daily work rate
of a Grass Roller used for seeding.
