BEDNAR ATLAS HO HEAVY DISC CULTIVATOR – PENETRATION AND SPEED IN ONE MACHINE!

By | November 20, 2016

The recent delivery of a 5.0mtr Bednar Atlas HO heavy disc cultivator to long-standing Te Kauwhata maize grower, Ned Kelly is the latest European cultivation trend for handling high levels of crop residue and heavy soils.

Putting the machine into work in early September the soil conditions were still very damp, but the machine made a beautiful job of discing the residue in and turning over a good amount of soil.

The Atlas HO really combines the weight and blade size of a heavy set of primary discs, with the level finish and working speed of a multidisc. Add to this the integrated rear roller and you have a formidable disc press for out of crop or primary discing.

A traditional set of tandem or offset discs are limited in the forward speed they can be operated at, too fast and you’ll leave an uneven finish that requires a lot of working down and levelling. The 660mm blades on the Atlas HO are arranged at a unique angle to give aggressive penetration from the 220kg spring loaded assemblies, and the 8.5 ton weight of the machine ensures it sits rock soild in the ground regardless of the huge amounts of residue associated with maize grain or sweetcorn.

One unique design of the Bednar machine is the X-configuration mounting of the blades. This creates dead even forces on the frame during work, meaning the implement tracks dead straight and allows full utilization of the working width on auto-steer tractors. See the machine in action below.

"We milk 2600 cows in both North and South Islands, plus grow maize and various crops on 600 hectares of lease ground. We are constantly developing new ground to bring into production and the 4AG 970's are excellent for chopping up old, heavily thatched pasture and contouring rougher areas. Daily throughput is important to our size operation. so we're pretty happy to be averaging 3-4 hectares/hour!"
