Well, I am not a pro by any means, but I do have a 100 pound pressurized sandblaster that I use a fair amount. Today, it went thru 300# of sand. But, I only use it on parts and not assemblies. It does a great job on parts, getting the paint off quickly, the surface rust from under the paint goes off next then the real rust goes last and uses a lot of sand and air. If you don't remove the caked on grease and goo the blasting will go much slower and won't do as good a job. So, in my opinion, you have to pressure wash the tractor first anyway. The tractor that I am doing now, 1963 Ford 4140 HD Industrial, was blasted at some point in the past. How do I know? There was fine sandblast grit under the shifter boot and in the grease. That is what you want to avoid! From the look of some of the other "repairs", my guess is that they weren't pro's at blasting! Around here, they charge $60 per hour plus sand used. If they are going to spend most of a day in prep, you are looking at $2-300 for that alone. Then about the same for the blasting and return to pre-prep condition. If they do a good job and don't get sand where you don't want it, it's probably a good deal. On the other hand, personally taking off the parts gets you real intimate with them and their condition. You can also repair/replace worn parts at that time. Either way, good luck! jb
