HE-VA King Roller behind John Deere tractor

KING ROLLER

Now even wider to cover more acres even faster

Supreme contour following ensures consistent, high quality results across the field. With working widths of 12.3m, 15.3m, 16.3m, 18.3m or 20.3m the new HE-VA King Roller meets the increasing demand for wider and heavier rolls.

A 15.3m set of Rolls travelling at 6km/hr with an operator driving at 90% field efficiency will cover 8.25ha or 21 acres per hour.

New generation rings come standard with a 5-year warranty.

FEATURES & BENEFITS

SAT System - Weight Transfer System

The King Roller's frame incorporates HE-VA's Special Active Transfer (SAT) weight transfer system, a Hydraulic Folding System linked to two accumulators and a hydraulic pressure gauge. The pressure gauge allows the operator to set the amount of weight transfer to ensure even consolidation across the full width. The accumulators act as an oil buffer when the rolls are travelling over uneven ground and the hydraulic cylinders need to extend or shorten to allow the rolls to follow the contours in conjunction with the centre pivot on each roller gang. 

The additional central support bearings on each roll support section ensure that the axles are not placed under excessive stress, which is crucial for a large roller.

Contour Following

The five centre pivots, two folding pivots and the pivoting drawbar eye allow individual sections to truly follow the ground contours.

The wing links and centre section frame allow these 5 sections an amount of vertical float independent of the other two sections to ensure contour following on very uneven ground.  


 

Heavy Duty Design

Built to withstand high workloads, the HE-VA King Roller is also heavier than most other like-for-like rollers, ensuring a better finish.

The King Roller's folding mechanism has a deep wing link pivot with Teflon coated steel bushing top and bottom to provide strength for working on cultivated ground as well as rolling after drilling.

The wider gang sections of the King Rolls have a centre bearing as an additional support.

The rings are mounted on 60mm axles for strength and long life. These axles run on 4 bolt multi-sealed bearings protected inside u-profile steel.

Transport & Storage

An automatic hydraulic locking system secures the wings for transport without any need to leave the tractor seat.

In the completely folded position the weight of the wings is carried between the tractor and transport wheels improving stability.
