The new 4-metre grain only version of the Great Plains Centurion cultivator drill was on view for the first time in the UK at this year’s Cereals show held at Boothby Graffoe in Lincolnshire.
The new drill, the Centurion 400, which boasts a new-look 3000-litre hopper design (a 4000-litre hopper is available as an option), is added to a growing Centurion range which also includes a new 3-metre version of the drill, the Centurion 300. The two new drills sit alongside the upgraded 6-metre Centurion 600 model. In addition, grain and fertiliser variants for the UK and Western European will be developed later this year in 6-metre, 4-metre and 3-metre widths.
The Centurion 400 features two rows of 460mm diameter cultivation discs with two choices of serration, 25mm or 50mm, which are mounted in pairs on maintenance-free hubs. Disc-to-disc spacing is 250mm and 650mm between the front and rear gang.
New heavy-duty cultivation disc arms with more robust, cultivation unit toolbar mounts provide increased clearance for stones and trash.
The cultivation discs run ahead of a tyre packer that offers highly consistent consolidation in front of Great Plains’ well proven 00 Series openers. A full width tyre scraper is available
The 4-metre drill sows 24 rows (at 167mm spacing) and 32 rows (at 125mm spacing), whilst the 3-metre version sows 18 and 24 rows respectively. Each coulter incorporates a seed flap guiding seed close to the opener bottom to eliminate seed bounce and an easy-to-use T-handle adjuster with 18 depth settings.
Hydraulically adjustable down pressure in the range of 40kg to 160kg ensures the coulters operate at consistent depth in all soil types and that the drill performs well in both plough-based and reduced tillage systems. New opener rail geometry maximises the transfer of weight to the coulter and press wheel by keeping the coulter arm parallel to the ground, ensuring accuracy of seeding depth and control over down pressure especially in difficult conditions.
The seed distribution system is variable rate ready. It comprises injection-moulded seed distribution heads with optional tramline shut-offs and seed blockage monitors to accurately deliver seed to each coulter with the ability to shut off each row individually for wider row spacing if required.
Great Plains has introduced a new meter housing design for easy access and a new modular seed drum system. Seed calibration is also easy and convenient. With seed calibration mode selected from the cab, the operator simply walks to the rear of the drill where a dedicated pipe delivers the metered amount.
The new drill folds to 3m for transport, with the transport weight being carried on the packer, with two wheels each side for stability and clearance fitted with 420/55 17 tyres. A full European lighting kit is fitted.
Hopper weigh cells can be fitted as an option. Working via the hydraulic control system, these ensure the hopper’s weight is evenly distributed right across the drill’s width no matter how much grain it contains. Other options include new hydraulic sprung track eradicators, hydraulic full-width levelling board, press wheel scrapers and harrows, bout markers, pre-emergence markers and air or hydraulic brakes.
Control is via a Mueller ISOBUS-ready system and a choice of display terminals is available.
Both the Centurion 400 and the Centurion 300 will be commercially available in limited numbers from autumn of this year.
