Years ago , Dad and my Uncle bought a new 120 John Deere picker. They used it for themselves and picked a lot of corn for neighbors over the years.  My Uncle died about 15 years ago and Dad died about 2 years ago.  I've been trying to find an operators manual or any other material on the 120 with no luck.  This is a great place for information and was hoping someone could give me some direction to try.                                           Over the years, our picker was pulled by a 1010 JD,404 international,1530JD,2840 JD,and a 2440JD.  It has always been kept in the shed and still a great picker.                     Thanks .   Jeff
