Opico’s HE-VA Sabre-Seeder offers ultra low-cost cereal establishment

If getting your cereal establishment costs down is a key objective then you’ll be interested Opico’s latest drilling development.

Delegates at a conference last week learnt of the firm’s three year testing programme of a disc harrow/seeder capable of high-speed stubble cultivation, cereal seed broadcasting and seedbed consolidation in one pass.

The Sabre-Seeder has been developed in association with Danish company HE-VA – which supplies Opico with most of its cultivation kit.

Its launch follows Opico’s extensive promotion of its low-cost ‘Till-Seeding’ concept for oilseed rape. The principal has now been extended to cover any crop and operation where cultivation and seed distribution takes place.

“The concept is a simple one, but has taken a number of years to perfect,” explains Opico’s managing director James Woolway.

“For a while we’ve had farmers asking us why cereals can’t be established off the back of a cultivator if you can get rape going in the same way.”

“One particular customer found that wheat spun on late in a wet season with a fertiliser spreader actually yielded better than that which had been drilled conventionally.”

“Of course it is not quite as straightforward as that and there are a number of agronomic factors to take into consideration.”

The Sabre-Seeder uses a fairly well-recognised layout employed for numerous shallow stubble cultivators.

Two rows of angled, serrated discs are responsible for cultivation and seeding. For this purpose an outlet is positioned on the convex side of the disc to drop seed in the freshly worked soil.

A 1500-litre hopper supplies a Rauch metering system – also used by Kuhn – and seed is blown to the outlets by a hydraulically-driven fan.

A rubber press-roller follows the discs to consolidate the seedbed.

Opico says the setup can be used direct into stubble or for a two pass approach, first incorporating trash and then producing the final tilth as well as drilling the crop in the second pass.

“On the right land, you could adopt a broadcast-only extablishment approach,” says Mr Woolway.

“Subsoil and seed on your rape ground to maximise the brassica’s rooting potential.

“Then cultivate and sow the land going into cereals – that’s Total Till-Seeding.”
