Gary, I am assuming that you mean that Deere does not have one of "their" 4n1 buckets for your 4200. I don't have a Deere or a 4n1 bucket, but I don't know of any reason that a WR Long 4n1 couldn't be put on your loader arms and plumbed into your tractor's hydraulics. I have talked to Long and it seems they have put their buckets on just about everything. You may have to find a dealer to work with you if you are not a technically inclined do-it-yourselfer. Long will sell direct or at wholesale to any legitimate dealer. You probably can get the Long bucket with the thumbswitch (the preferred implementation) instead of the separate lever that JD seems to install....I'm not sure of all this, but it is worth a call to Long or Carver if your JD dealer is ignorant.
