Greetings from the frozen state of Vermont. I am a skidsteer wannabe in search of specs for older machines. I need a machine which will lift at least 1500 lbs, and has constant flow auxillary hydraulics to operate a tree spade. Since I would probably not use it more than 50 hours per year, an older model would be fine - in fact preferable to a newer one. I have seen such units as a Case 1537, Bobcat 610, and John Deere 36 for sale, but am unable to determine much about them except what appears in the ad. A few weeks ago I ran across a web site which I thought would give me all the necessary info on older units, but it wasn't as comprehensive as advertised, and now I can't find it again. Any leads you guys from cyber space can provide will be much appreciated. Thanks in advance.
