No-till Drill Parts & Equipment
20% more wear-life than the next-best, which was our old standby from Ingersoll-Canada. The Forges de Niaux takes it to the next level with a unique steel and special heat-treat process. Same dimensions as OEM. Replaces John Deere Part number N283804.
Now available: Forges de Niaux’s superior blades for Case-IH Precision Disc 500 / NH P-2080 / 2085. Same dimensions as OEM, but with the greater durability of the Forges de Niaux! Harder on the periphery, for 20% greater wear life. Stays sharper longer. (Note: We don’t stock these in our warehouse; all orders will incur shipping.)
All About Opener Blades
Perhaps because of the light we shed on the matter, JD and some aftermarket companies have improved their game with higher quality offerings. We have too, with the Forges de Niaux 200—which is even stronger and has 20% more wear-life than the next-best—our old standby, the Ingersolls. The general hierarchy for wear-life, sharpness, and quality/consistency is Niaux 200 > Ingersoll ≥ Bellota (JD since 2016) > Osmundson (JD 2015 & prior). The Forges de Niaux truly takes it to the next level. Exapta brings you the best of the best.
Blade sharpness is critical, and we were advocates of frequent blade replacement long before we ever started selling any opener blades. Dull blades hinder the cutting of straw and stalks—resulting in hairpinning, i.e., tucking the residue into the furrow with the seed sandwiched in the middle—as well as poor cutting of the soil itself. Attempting to overcome this requires more down-pressure and frame weight, sometimes a great deal more.
A few companies are selling aftermarket blades that are larger diameter than OEM, which is 18″. This is undesirable for a couple reasons: First, larger blades result in more hairpinning (unless you’re planning to cut a furrow 5″ deep). For seeding depths of 1.5 – 2.5″, you really want blades that are only 15 – 16″ diameter; 18″ is a bit too large already. Secondly, if you typically seed about 1.75 – 2″ deep (and this is where these drills work best), going to a larger blade will create more of a gap between the lower edge of the seed boot and the soil surface, causing more seeds to escape (and lowering the boot to the bottom hole may not put the boot at the proper spot either, depending on the exact blade diameter being used).
20% more wear-life than the next-best—our old standby, Ingersoll-Canada. The Niaux 200s also stay sharp longer. But the additional wear life on the Niaux 200s doesn’t impair their toughness, because the extra hardening occurs only on the outermost inch or so (also, they use a different steel to handle the additional hardening—it’s not the usual 15B30 steel that all the other blades are made from).
Exapta’s Ingersoll on the left, Osmundson on the right. Ingersolls are the sharpest of any blades for these drills, and have very good longevity—exceeded only by the Niaux 200s. Ingersolls from Exapta are still a great value.
While Niaux 200s last 20% longer than Ingersolls, and stay sharp longer, Ingersolls in turn typically have a 20% wear-life advantage over Osmundson. Not to mention the Ingersolls are much, much sharper when new.
