Kverneland has revamped its range of DG trailed disc drills, adding an improved folding mechanism to make them better balanced and easier to manage on the road.

The so-called DG II machines are available in 9m and 12m working widths and are fitted with the firm’s CD double-disc coulters – the smaller model has 72 units and the larger one has 96, both with 12.5cm row spacing.

Balance during folding has been improved thanks to a hydraulic weight transfer system.

This is integrated into the cross-shaft that attaches the drill to the tractor’s lower link arms and automatically tightens during folding and unfolding.

The net result is that the drill remains stable throughout the process and that means it can be operated with a smaller, lighter tractor – typically 200 to 250hp.

Simplifying the design of the hydraulic folding mechanism for the seed distribution heads has also helped keep the transport dimensions to 3m wide and 4m tall.

Other updates include a system called Active-on, which balances and maintains pressure, both laterally and longitudinally, across the full working width of the coulter bar.

The idea is that this improves seed placement depth, while delivering up to 80kg of coulter pressure.

The DG II drills are Isobus controlled and feature two electrically driven seed metering units – one to feed each half of the drill.

Seed hopper capacity is 6,000 litres and there’s the option of adding a seed-flow monitoring system to warn of blockages.

Optional extras include a hydraulically adjustable clod board and a 12mm finger tine harrow in place of the S-tine following harrow.

LED lighting, dual track eradicators and hydraulic bout markers are also available.
