[QUOTE="Simon Chiles, post: 5574540, member: 1233"] The disc in your photo definitely has quality issues, it shouldn’t wear like that. I’d be amazed if JD didn’t replace those couple of discs. I can’t see anything wrong with the discs in the background, they look normal. Is the manufacturers code ( not the part number, it starts with 3 letters and then a number ) the same on the discs you have issues with as the the ones that are ok? You can’t spec better quality discs ( at the moment) from JD. Donkey’s years ago I was changing a set of discs every couple of weeks with the workload and soil type I was working on at the time. When I suggested that I needed something better they supplied me with JDS100 ( the standard for disc quality ) on the understanding that if I revealed it’s contents I’d be shot at dawn. Having studied it and after having a chat with some engineering friends I suggested to JD that we needed discs of 55 HRC. They supplied me with sets that came directly to me from the manufacturer. The difference was dramatic, I went from changing discs every couple of weeks to changing once a year ( 2500 acres ) and even then they weren’t completely worn, I just stuck a new set on before I started drilling beans. The discs then became available from JD for a time but they were £60+. I suspect that ( apart from me ) nobody was prepared to pay this sort of money for discs when you can get cheaper discs for the mid £20’s so JD reverted back to the original spec and reduced the price accordingly. I keep asking for a better spec disc but the reply I get is that I need evidence that customers are prepared to pay the extra for them. [/QUOTE]
