I have recently purchased all of my equipment and I went through the looking process for about 6 months. I was looking for the best deals I could find due to being on a very low budget. I found alot of 5' shedders, between 175 and 250 for good used ones. I needed a 4' though and those are hard to find, I finally found a old 4' mohawk, good condition and worked very well for 150. Used 5' box blades and scraper blades are a dime a dozen, I found lots of those, very few at 50, buts several between 75 and 200. I bought a old KK 6' scraper blade for 125. You gotta watch used PHD'S most of them are already junk and if you find a good one the price is still pretty high. I bought what looked to be a dinasor, just a big rusty piece of metal. The guy said it still worked, said i could bring it back if it didnt. Said he had just used it putting some post around his salvage yard. I paid 150 for it, it did work, but big and bulky and hard to use for me. I can drill holes faster with my little beaver earth drill, just get tired of walking with it. I bought a 16' tandem axle trailer, (no axle brakes) needed lights, wiring, and floor for 300, then cost me about 100 for me to put the floor in and 30 for lights and wire, I think that was the best deal I had come across. Those trailers used are around 750. I dont know about your tractor, I hear talk that the vet. rebuilds arent very good, that would just be between you and whoever likes it wants to pay.
