Scotts Evolution  Dirt Eliminator primary role is to gently separate clod, stones, haulm and loose soil from Potatoes, Salad Potatoes, Sweet Potatoes, Onions, Carrots…

Thanks to multiple set-up, it can be used either in dry, wet or very dirty condition.

The Evolution Separator generally works by extracting the debris between 2 contra rotating rollers.

The larger roller (spiral roller) has air chambers and is deformable with a spiralling rib.

The smaller roller (clod roller) is smooth with a choice of finishes.

The clever design of the “spiral rib” entrains the debris down into the valley between the rollers where, if the debris if soft enough is then crushed and ejected down below the separator.

Stones will also pass between the rollers as the “spiral roller” readily deforms around the stone so does not allow loses of crop at this time.

If larger stones enter the valley and there is not enough deformation in the spiral roller there is a safety mechanism that allows the clod roller to spring away momentarily to allow the stone to pass through.
