One of my inlaws neighbors has a several hundred acre farm. He used to raise beef cattle. Several years ago he had medical problems that put him out of business. Now he leases out most of the property for crops. The people leasing have all of their own equipment. He has 3 JD's in a run in shed. The smallest is a 2510. I've been looking for something in the 50HP range. The tractor is straight, clean, no grease, as in dripping or caked all over, brand new tires on the rear. If it is in good running condition, which knowing how he takes care of his equipment, it will be. What should I expect to pay, or offer him. I looked on tractordata and they only made that model for 3 years in the 60's. I have a Massey 135 in about the same shape that I paid $1000 for. The Massey is a Z145 gasser, the 2510 is a diesel. Thanks, Joe.
