HE-VA ring types
Cambridge
The Cambridge-ring is a universal ring consisting of alternately plain and breaker rings. This ring efficiently consolidates stones and the bended profile is gentle on germinated plants. This particular combination results in an optimal crushing and packing effect and the and the great mobility of the breaker ring makes it highly self-cleaning.
Star
The Star ring is often chosen, when the roller, besides doing the normal roller-jobs, is also used for soil packing and seedbed preparation. The Star ring works very well in both light and sandy soil types as well as in heavy and og sticky soil types. When used for light soil types, the surface is left slightly packed and uneven, which prevents drifting soil. In sticky soil types, the rings' self-cleaning effect is of great importance. The Star ring furthermore has a great draining effect on grass fields as the points make little holes in the field.
Cam
The Cam ring is most efficient in very light soil types like loose and sandy mould due to the fact that it divides the soil into fine particles and packs it leaving a porous surface with little clods, which help prevent soil drifting.
Crosskill
Crosskill-rings are often used in light and medium-heavy soil types. The rings crush clods and leave the surface slightly crumbled, which prevents soil drifting. These rings are self-cleaning, which only increases the effect of the rings.
Wave
Wave rings create a level surface completely free of stones, which is of great importance when seeding particular types of crop. It is often used for consolidating germinated seeds as the rounded design is gentle with the plants.
