NEW BioBlade® Drill Opener

BioBlade® has been designed in NZ by the inventors of Cross Slot® and is exclusively licenced worldwide to Giltrap Ag for Duncan Drills. The BioBlade® combines the latest pasture renovation science with the solid and dependable reputation that are the cornerstone of the Duncan brand.

Two household farming brands. One vision. Increased growth - stronger returns for you.

• Designed for pasture renovation and forage cropping without prior tillage. Can operate in tilled soils too.

• BioBlade® makes true inverted-T shaped seed slots continuously.

• BioBlade® self-closes the inverted-T shaped seed slots with following press wheels.

• BioBlade® soil slots are filled with high-humidity soil-air promoting high emergence rates.

Most seeds can germinate in high humidity soil-air alone without the need for visibly damp soil or rain. This fact has been scientifically proven and has won several science awards for its importance.

• BioBlade® can simultaneously sow “non-burn” fertilisers, with the seed and fertiliser mixed in the same slot.

• BioBlade® handles surface residues better than tine drills.

• BioBlade® is ideal for depth-sensitive species like clovers, plantains, fescue and chicory.

• The seeding depth of BioBlade® openers is adjustable in groups of three. The depth is controlled by separate gauge wheels.

• BioBlade® uses leaf springs to allow vertical travel of openers.

• Designed to fit into an affordable self-ownership price bracket. Get most of the biological benefits of a Cross Slot opener without the high cost.

The BioBlade® design has been deliberately crafted to always preserve the all-important inverted-T shape of the seed slots.

Duncan BioBlade® drills will be available to purchase from 2027.
