Don't just roll - Cultivate, level and consolidate all in one pass! By switching to HE-VA Cambridge Rolls technology you will reduce
your time and costs and improve effectiveness.
HE-VA now offer a Shattaboard, Shattaboard with slicing plates and an
S-tine board to turn their Cambridge Rolls into an all round cultivator. Coupled with a
wide choice of ring types this means you can specify the right machine to
suit any type of land.
Real power in action - firming and levelling
with clod busting or slicing, cultivating or
combinations of both, on top of full width
rolling action.
With this choice of combinations and working widths from
4.5m to 12.2m, HE-VA Cambridge Rolls can meet the demands for
improved efficiency regardless of farm size or soil conditions.
As the HE-VA wing sections are suspended
from the central pivot the Cambridge Rolls can follow
the most difficult contours. Deep hollows
and undulations in the ground will often
leave ordinary rollers hanging in mid air,
achieving nothing.
HE-VA always give FULL width
rolling power
3 section Cambridge Rolls with contour
flexing chassis, centre
pivoting wings and the
unique SAT -1000kg
automatic weight transfer system.
5 section Cambridge Rolls with SAT system
independent flotation on all 5
sections thanks to the additional
spring system built into the end
section pivots and centre roll.
Cambridge Rolls without HE-VA automatic weight balancing tend to exert the highest
ground pressure on the centre roller section. This roller section carries the
weight of the drawbar, wheel frame and hydraulics as well as its own
weight, far more than the two wing sections
With a basic roller set up there is no weight transfer and
the uneven weight distribution is great as can be seen above.
Even with a basic sprung weight transfer system the hinges at the
end of the centre section roller negate much of the transfer effect.
The HE-VA SAT system is fully spring loaded and has the outside roll
section attached with centre pivot hinges, maximising the weight transfer
to give even weight distribution across
the full width of the Cambridge Rolls.
The Cambridge Rolls, Tip Roller and Swing Roller folding mechanism has a deep wing
link pivot with Teflon coated steel
bushing top and bottom to provide
strength for cultivation as well as rolling.
Stone trays are fitted as standard and the Cambridge Rolls are all
hydraulically operated from the tractor seat using two
double acting services.
There is a choice of five ring types along
with two 'boards' which can be fitted in
front of the Cambridge Rolls for the additional
cultivation action.
Although designed to cope easily with bigger
farms and larger hp based systems, the 5
section Cambridge Rolls are still easy to handle - simple to
fold and capable of devouring many acres of
work in a day. The rings are also mounted on 60mm
axles with 4 bolt bearings.
The two outside wing sections are supported
by deep wing link folding mechanisms with
an additional jump slot for increased flotation
and for working field edges.
The clever design of all HE-VA Cambridge Rolls also
ensures that tractor drawbar height variation
(400-600mm) does not alter the performance
of the Cambridge Rolls.
5 section Cambridge Rolls design features independent
flotation on each section. The centre pivot
suspension gives full width contour following.
Even the centre section floats independently.
The King Roller frame incorporates HE-VA's Special Active Transfer
(SAT) weight transfer system. Comprising five sections, each
with central pivoting, the King Roller adapts to the contours and
consolidates the ground as effectively as any of the other Cambridge Rolls in
the HE-VA range.
Available with 21" (510mm)
or 24" (620mm) rings, the
King Roller quickly folds down
horizontally to a transport
width of less than 3m.
The five centre pivots, two folding pivots and the pivoting
drawbar eye allow individual sections to follow the contours. The
floating inner links, which join the outer wing sections to the main
frame, allow all five sections to float completely independently,
providing the best possible contour adaption.
All carefully designed to maximise the time proven
qualities of traditional ring engineering but with some
new developments created from customer demand and
changing farming methods.
This is where your cost savings start - work as you roll ... level, firm and crush clods,
all in one pass.
Cultivate? Prepare a seedbed? Or conserve moisture - flexibility is the key.
ShattaBoard
Slicing Board
Locking Device
The spring mounted Shattaboard crushes
clods and has an excellent levelling effect.
The angle of the boards can be adjusted
hydraulically from the tractor seat to suit
the land conditions on the day. Each spring
is 10mm x 80mm and gives wide surface
coverage with 150mm wide
hardened points.
Now the successful Shattaboard has been
improved further with the addition of
'knives' to the spring-loaded blade increasing
the slicing and clod breaking effect on
heavier ground. These blades can also be
adjusted for angle of attack, hydraulically as
with the Shattaboard (left).
The blades can work individually but
the levelling effect is increased with the
addition of the optional locking bars to
convert the individual springs into a
complete 'board' for full width action.
The boards can be quickly and easily retracted for rolling seedbeds. Whichever combination of cultivation tool and ring you choose the HE-VA system gives you the
opportunity to produce the perfect tilth at less cost.
