GRASS ROLLER

Weight Transfer System

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, dependent on ground conditions and how much water is in the roller sections.

Grassland 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 above the middle roll section.

Even with a basic sprung weight transfer system the hinges at the end of the 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 rol

CULTIVATED GROUND - Not only can you use the HE-VA Grass Roller to consolidate grassland, it is also ideal for work on cultivated ground.

With the addition of two rows of harrowing tines and a levelling bar, you have a very useful multi-purpose field roller for existing grassland for thatch removal or seedbed preparation. A HE-VA Multi-Seeder and mounting kit is also available. 

Contour Following

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 adaption.

Water Ballastable Rolls

The weight of the 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 to Work in Seconds

HE-VA's innovative folding system allows the operator to fold or unfold the machine from the tractor seat in seconds using only two spool valves, when folded the wings are effectively locked automatically for road transport.

Rounded Roller Ends

The Grass Roller is made with spun chamfered steel ends on each section, these ensure that there is no damage done to the grass when turning sharply on the headlands. Drum thickness: 610 mm tube = 10mm, 710mm tube - 11mm.
