Consolidates evenly across the full width of the discs

Sharp edges cut and fissure large clods

Each ring mounted on a square axle ensures all rings turn together to maximise clod crushing

The Prisma Ring -

45mm Square Shaft ensures all the rings turn together maximising clod crushing and preventing bulldozing on light soils

45mm diameter special Cast Ring - resists damage

Sharp Prisma edges cut through large clods

The Angle of the Prisma ring ensures consolidation below each ring and between adjacent rings

The conical groove between each Prisma segment ensures the ring cleans itself in wet conditions

Prisma Rollers come in segments that are maximum 1.6m long

The grinding action of the Prisma breaks up clods in the top layer of the soil but leaves some small clods on the surface to prevent capping

Larger cobbles on top to prevent capping

Fine soil at seed depth gives ideal germination conditions

Scraper system cleans and prevents clods and stones jamming between rings

Good even consolidation and clod breaking

Additional consolidator paddle levels on light fluffy soil
