HE-VA Grass Roller

THE HE-VA GRASS ROLLER HAS ALL YOUR NEEDS COVERED.

The Grass Roller or Ballast Roller uses existing HE-VA Rolls technology to solve an increasing problem for today’s grassland farmer and contractor. With farms and fields spread over growing distances and yet needing the same attention from a heavy ballast roll in the spring that they have in the past, the HE-VA Grass Roller combines working widths of 6.3 or 8.2 metres and hydraulic folding for fast, easy transport.

The frame incorporates HE-VA’s SAT weight transfer system and central pivoting of each section to ensure the water filled sections can adapt to the contours and consolidate the ground as effectively as a single roller.

The two centre wing pivots, 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 ballast roller sections to float completely independently and you have the best possible contour adaption.

1, Ballast rollers 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 above
the middle roll section.

2, Even with a basic sprung weight transfer system the hinges at the end of the
centre ballast roller section negate much of the transfer effect.

FREE FLOATING BALLAST 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 Grass Roller 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 dependant on ground conditions and how much water ballast is in the ballast Roller sections. The accumulators act as an oil buffer when the rolls are travelling over uneven ground and the hydraulic rams need to extend or shorten to allow the rolls to follow the contours.

Add an OPICO Air Seeder to the ballast roller and you have a truly multi-purpose HE-VA machine, which can also be used for over seeding and reseeding grassland.

Not only can you use the new Grass Roller to consolidate grassland, it is also ideal for work on cultivated ground. With the addition of the harrowing tines and levelling board, you have a very useful tool on existing grassland or for seedbed preparation.

GRASS ROLLER LEVELLING BOARD
When being used on grassland the adjustable spring loaded levelling board can be used to level off mole hills and manure whilst on cultivated ground it can be used for final light levelling of a seedbed.

GRASS ROLLER - TWO ROWS OF 12mm TINES The Tines are good for scarifying grassland, ripping out moss and dead thatch and exposing bare soil when overseeding or final cultivation when working on cultivated ground.

GRASS ROLLER - WATER BALLASTABLE 710mm TUBE
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 land.

READY FOR WORK IN SECONDS

HE-VA’s clever Rolls 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 transport.

OPTICAL SEEDER KIT PROVIDES COMPLETE SOLUTION

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.

Mechanical or Electronic OPICO Air 8 seeders fit the 6.3m Grass Roller and are suitable for overseeding applications, the landwheel giving consistent seed rate  application no matter what working speed the machine is used at.

The OPICO Air 16 Seeder is suitable for either the 6.3m or 8.2m ballast roller s 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.
