Subsoiler busts yield robbing compaction

Subsoilers busts yield robbing compaction. Subsoilers busts yield robbing compaction.

Designed for deep vertical tillage, the Great Plains inline subsoiler shatters yield-robbing compaction layers.

These layers are a known effect of horizontal tillage tools such as ploughs and discs, and of tractors or continuous repeated traffic. 

The subsoilers have a working depth of 30-40cm with easily adjusted depth wheels. They are designed for use in autumn to help loosen the soil profile and restore uniform density but with minimal topsoil disturbance.

The subsoiler’s frame is made of high tensile, 9.5mm walled tubing for strength and durability. They come with 70cm (6 shank) or 75cm (5 shank) spacings. 

A no-till, 25cm wide, winged point is used with the 19mm no-till leg to minimise surface disturbance yet maximise the soil shattering effect below the surface. 

At the rear of the machine, individual 41cm diameter roller assemblies, made from 2.5cm solid bars, level the treated surface, enabling single pass seedbed preparation.

The shanks are protected against stones, rocks or timber by a horizontally mounted coil spring protection system with a trip force of 1360kg.

Thinking about subsoilers, few farmers in New Zealand and beyond will be unaware of the McConnell Shakaerator; after all it's been around for 35 years.
