I just bought a5215HST D.A. tractor from a J.D. dealer . It had been sitting in his yard for 4-5 years. I am looking for O.M and Tech Manual .It shows 200 hrs on the tach and looks real good .I ran the tractor on a 72 " mower for 5 hrs with no problens . I have an AGCO dealer close by . Are they a good source for parts ?
