I am trying to track down two ASV MD 70 Serial #. One is PTO840-JWPDT, 1997 Model per ASV Corporate search. The other one is PT840-DWDD. 1993 model The reason being as the machine I bought from a Troy A Schumacher, was suppose to be a 1997 ASV MD 70, When it broke down after less than 10 hours of operation, I was checking for parts and checked the serial number on the machine and it was PT840-DWDD. I called Schumacher to verify the number and he told me he got the number off the post of the machine, I explained to him that this was not the number that I had and He stated that" that was the serial number he got off the machine and had called ASV to verify the year? So I am trying to find out if anyone has the PTO840-JWPDT, so I can perhaps prosecute MR. Schumacher and get some of my money back. 1993 models have different parts and are much more expensive to operate. One of the Danfoss Drive Motors was leaking profusely, and I had a hard time tracing the leak as the oil leaked out on the ground right next to the track and I wasn't parking it on cement, so the ground absorbed the oil. It is my opinion that Schumacher knew about the problem because he stated he had parked in in his shed, which had a cement floor. So any info I can get would be helpful, perhaps someone out there has had dealings with Troy A. Schumacher of Rice Lake WI? Thank You, Art
