I have the misfortune of having my 2720 high pressure line blow out now for the second time. I am looking to any and all 2720 and 2520 owners to sound off on this issue if this has ever happened to your machine. When this happened the first time , my dealer replaced the line and said JD was aware of this issue with these tractors. Now , with 300+ hours the line has ruptured again in the same weld seam as before and they are denying there is a problem. I have read here, and on other forums, where these 2720's and 2520's have been having these lines fail, since back in 2007. I am also dealing with John Deere directly and getting a run around on this issue. Hopefully. enough people will see this and sound off on it here, so I can send this off to them as proof. I have video taped the leak, and sent it off to JD who claims they have no way to view the video. I say hog wash!! this is 2013 , find a way!! all help in needed here, as I ill never give up on this issue. someone has to stand up.
