John Deere SP22 Series

Compression springs

The SP10 Series Soil Pulverizers have two 68-kg (150-lb) compression springs, and the SP20 Series Soil Pulverizers have two 72.6-kg (160-lb) compression springs to keep the roller in contact with the ground and force the spikes into the soil down to 25.4-mm (1-in.) deep.

Cutting teeth on SP20 Series Soil Pulverizers

The SP20 Series Soil Pulverizers feature a double set of 12.7-mm x 50.8-mm (0.5-in. x 2-in.) bar-type cutting teeth. Their staggered mounting slices the surface every 71.1 mm (2.8 in.) for superior soil preparation.

The teeth are reversible for extra life.

Frontier™ soil pulverizers are easy to hook up

The iMatch quick-hitch system converts the tractor's 3-point hitch to fixed hooks for a super-quick connection.

Steel rollers provide enhanced precision

The steel roller on all SP Series Soil Pulverizers are studded with 9.65-mm x 25.4-mm (0.38-in. x 1-in.) spikes that penetrate the toughest surfaces, breaking down clods and creating a fine finish.

Add an optional second roller with two 36.3-kg (80-lb) compression springs for an even smoother finish.

By installing a second roller assembly kit to soil pulverizers, the second roller helps smooth out material after it has been pulverized.

The field-conversion second roller assembly kits below are identified by part number and the specific soil pulverizers each kit is for.
