Guest Posted April 12, 2002 I just picked up an Ark model 515 loader that was on a 416 tractor. It looks to be in pretty good shape. The S/N is 501....could they of started at 500? Will this loader fit any other models with out too much modification? Did Ark make loaders for any other brand of tractors? How common is this loader. Sorry about all the questions. Thanks!!!
