I just got a simplicity 5216 with a snow blower attachment. It doesn’t t look like any other simplicity blower I have seen. It does bolt to the frame and seems to be in decent shape. The only problem is the belt tensioner to engage the blower. If it’s missing something I don’t have a problem fabricating parts, I just don’t know how it is supposed to work. The raise/lower handle twists to engage. Also I don’t know the manufacturer. The patent tag says HMN
