[QUOTE="Simon Chiles, post: 5721104, member: 1233"] I’d be amazed if it was that simple, if it was why don’t JD make their own. Having been to several of their factories and watched their plasma cutter cut out the side of a combine in seconds it wouldn’t be difficult to load it up with a pallet load of Hardox and it would have cut out several thousand in one of their lunch breaks! I was at a machinery show quite a few years ago standing next to a 750 when a smartly dressed Indian gentleman started quizzing the salesman about the drill. His reply to him was that it was no good asking him, it was me he needed to speak too. During our conversation I asked him what his interest was in the drill as he very obviously wasn’t a farmer. He said that he was the largest manufacturer of agricultural discs in the world, so obviously we started talking about disc quality and he said that they couldn’t make discs to 55HRC and that there was ( at that time) only one manufacturer it the world that could, which was something I already knew. The reason he gave me for most factories not being able to manufacturer to this standard was that they couldn’t control the heating and cooling cycles accurately enough. His conclusion from our meeting was that he was going to go away and see if they could improve their quality of production, as he said to me, it would be better to complete with the Chinese on quality rather than a race to the bottom as to who could make them cheapest. If making these discs was as simple as knocking them out of Hardox with a plasma cutter why don’t all these manufacturers with massive factories do it? I suspect that the answer is in the JD specs. Of those 30 pages only about half a page is about hardness, the rest is about resistance to deformation, cracking etc. Ask anyone who farms a lot of soil with flints and they’ll tell you that when they switch to a 750 they end up with twice as many flints, they’re just smaller. It’ll give you an idea of all the other properties a disc needs to have other than just hardness. [/QUOTE]
