[QUOTE="Ground Gear, post: 7721624, member: 162099"] Attached is some images of this independent test, across many different soil types in the Canterbury Plains in spring and autumn direct drilling and over 800 hectares. For further detail, hopefully is well covered, just pop a message back on the forum. The test compared directly 3 different blades FDN NX 200 against a major aftermarket blade from Spain and the JD oem with all the test blades fitted in neutral positions (outside of the wheel tracks to ensure fairness) it was how sharp the bevel remained on the NX 460 mm disc that was the eye opening thing, the JD oem blade was respectable whereas the after-market blade from Spain had completely lost the bevel (was very blunt and next to useless for discing through reasonable volumes of stubble or residual from Kale crop typically found on these farms). As far as weight and diameter of blades all were similar in which case one of conclusions was what is it that you are actually wanting out of a drilling disc having maximum longevity but the drilling edge is completely blunt and wont cut through anything so needs to be replaced prematurely? By the way OEM blades are not neccesarily guaranteed to be the same blade from the same supplier year in and year out. As insurance against out of stocks they would typically have two companies that supply them. JD for a long time were fitting drilling discs from a manufacturer in the US called Osmundson.
