Tramlining can cut those seed losses

WORKING on the Rabe plot was the 6m Turbodrill power harrow/drill combination, which can now be fitted with a front mounted 2300 litre seed hopper.

Reducing the loading on the rear of the tractor by some 2.5t, the hopper uses a hydraulically driven fan to deliver seed through two pipes to distribution heads on the rear-mounted drill. The distribution heads supply 48 coulters mounted in two rows.

The drills special design feature, says Rabe, is the tramlining control which reduces seed losses by 4% due to seed being recirculated back to the front hopper. Further efficiency is achieved using the drills computer – responsible for automatically adjusting rates according to the forward speeds.

Available in partnership with Rabes VKE 6m folding power harrow or optional cultivator, the combination can be specified in 4m and 5m working widths.

Also from Rabe, was the 5.8m trailed Power Bird cultivator, employing – not duck – but goosefeet tines. Working to 15cm (6in) depth, the tines are plasma hardened, which Rabe claims, extends their life by up to two thirds.

The Power Bird is also available in a 7.5m working width, or for the smaller grower in 4m, 5m and 6m mounted versions known as the Blue Bird.
