Nick, I have a QA42A that I picked up years ago as a spare. I have never used it so I can't say how well it works. It would need a belt, a new wear/cutter bar and a little bit of repair to one end of the auger housing where it appears to have hit something and bent the left side of the auger housing back, see photo for detail. The gearbox feels tight, but the driveshaft has some play in the keyways, it might just need new keys. It's a 4 paddle auger with typical wear on the auger flights. The chain adjuster looks to be in good condition. I don't know if the lift rod is the correct one for it or if it's one for my other QA42, it's 32" long which is the same as the lift rod for my QA42 I use on my 125. Perhaps someone can confirm the length for a lift rod for a QA42A on a 1450. The skids are worn down but appear to never have been flipped so the other side has plenty of wear left.
I'm in the Somerset, WI area which is just around the 100 mile mark from you, perhaps a bit under. I'd like to get $150 for it.
