42" Dozer blade yellow in color and stenciled in black paint is "2025015  No. 1 of 1" on left side of blade ( left side when sitting on tractor). This came off a late 90s MTD tractor but when looking up blades for that era of MTD tractor, the blade for them looks nothing like this one. So I researched the # I found on the blade and it came up a # for an A/C B1 (and possibly others) from 1966 to 1969 approximately.  I looked up pictures of that blade and this one does look identical. The mount however looks very similar but a little different. It appears as if someone modified it for an MTD tractor or made a new one? I am not sure.  I am listing it in the classifieds because I do want to sell it, but I am not sure it really is an A/C blade. I am only going off the # on the blade and the brief research I did on it. I am actually a Bolens tractor collector and replaced the tractor this blade came off of with a 1964 Bolens 900. I have since bought 2 more! (1050 and 1053) I gave the MTD tractor away but was going to sell the blade. While researching the part # on the blade I found this site (it came up in the 1966 and 1969 A/C implement list). I figured if it was an original vintage blade I would rather it go to a collector than someone with a disposable MTD tractor. I joined the site to list this item and hopefully it is an item someone will want and can use. If anyone has info on this blade I am curious to find out what you might know. And I do want to sell it. It is in very good condition with virtually no rust. It has heen painted black over the original yellow. Tire chains, weights and all brackets for the MTD tractor goes with it.  $200 OBO. Thanks!
