Danish firm Dal-bo has come up with nifty kit that converts a subsoiler into a disc drill for establishing oilseed rape.

The coulter bar and hopper arrangement bolts straight on the back of any Dal-bo subsoiler and places the seed in defined rows and at a set depth. Dal-bo says this gives much more accurate seed placement than systems that drop it behind the subsoiler leg or broadcast it across the entire width of the machine.

Seed is distributed down six tubes to a row of six double-disc coulters. There’s also a 12-coulter option that comes with splitters to convert the six pipes into 12 outlets.

Seed-rate is controlled with a simple unit in the cab and there’s the option of a land-driven metering wheel or radar.

There are also brackets available for mounting to rival makers’ machines. The kit costs £14,000.
