The ongoing running costs of tillage machinery is an increasing factor considered by today’s farmers and contractors.

The large geographical variety of NZ’s soil types and terrain with often abrasive and rocky conditions, caused 4AG to track down the best quality ground engaging steel in the world. In our worldwide search for the no. 1 product, one name just kept on popping up, as the recognized leader in the shaping and heat treatment of the highest grade of boron steel. ‘Forges De Niaux’, from France.


Forges De Niaux were the world’s first company to manufacture blades from boron steel. In the last decade, after further years of extensive research and development, the became the only manufacturer globally to successfully produce blades to a hardness of 200kg/mm² (60 HRc Rockwell hardness), hence the name of this new industry standard in disc blades is ‘Niaux 200’.


Brownrigg Agriculture is one of the largest cropping operations in the Hawkes Bay region of the North Island, growing large areas of squash for export and maize grain as well as an intensive livestock trading operation. Brownriggs run a 6.6mtr Great Plains/Simba X-press, and purchase ‘Niaux 200’ disc blades for this machine from 4AG. They are very impressed with the extra life and wearing properties they are getting out of the Niaux 200 blades. Sam Lindstrom (cropping operations manager) gave an example of a direct comparison between the Niaux blades, and the OEM blades they had previously been fitting. ‘We are doing thousands of hectares each year with this machine, so blade wear and wearing metal cost is something we watch closely’.


‘In the autumn (2016) we re-bladed the whole machine prior to working our maize grain stubble. We fitted the Niaux 200 blades on the front row of discs, and the original Simba blades to the back row of discs, both blades were identical new diameter of 510mm. We knew this unfairly disadvantaged the Niaux blades because typically the front row of blades wears twice as fast the back row, due to being more exposed to soil and trash and first into the ground, but we had good experience with these blades so decided to do it this way’.


‘In March a rep from 4AG visited and we showed him the blades, by this date the machine had worked 1800 hectares of ground on the new blades. To our amazement, the Niaux blades on the front were quite a bit bigger than the original blades on the back row!. When we measured these up the Niaux 200 blades were 460mm diameter, and the rear originals were down to 410mm diameter, this was very impressive considering how much harder the wear is on the front row!’ This fact is clear for us, we can’t go past Forges De Niaux blades. We also fit them to our larger Simba SLD 460 disc ripper, and Case 770 6.0mtr offset heavy discs.


4AG stock blades to suit most brands from multidisc and seed drill blades for Vaderstad, Simba, and up to the larger 24”, 26”, 28” 30” blades for heavy primary discs. Give them a call today for competitive pricing and fast delivery.

"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!"
