Rolls Features

As the HE-VA wing sections are suspended from the central pivot the 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

Stone trays are fitted as standard and the rolls are all hydraulically operated from
the tractor seat using two double acting services. There is a choice of six ring types along with three ‘boards’ which can be fitted in front of the rolls for the additional cultivation action.

Rings are mounted on 60mm axles for strength and long life. these axles run on 4 bolts bearings protected inside u-profile steel.

The axle on the wing sections of the 8.2, 9.5 and 10.2m Tip rollers have a centre bearing as an additional support.

The 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.

Although designed to cope easily with bigger farms, and larger hp based systems, the 5 sections rolls are still easy to handle - simple to fold and capable of devouring many acres of work in the 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 rolls also ensures that tractor drawbar height variation (400-600mm) does not alter the performance of the rolls.

5 section rolls design features independent flotation on each section. The centre pivot suspension gives full width contour following. Even the centre section floats independently.
