OutdoorKing Repair Forum Forums Collectors Corner Rotary Hurricane 4 - What is this mower?

I have been asked by someone on Facebook identify there mowers so they can sell, It was an easy task, with most mowers given a name, rought date and rough price. But one mower i could not identify. I am sure someone on this page, most likely Jack, will know what this mower is. So far the only other one i have seen was on ebay, it started at $30, but over a couple months it droped to $15 and another engine was added to the sale. I did not want to tell them that that is what its worth until i knew a name and some info behind it. What i find very interesting about these mowers is the "4" on the front of the base, i have seen plenty of mowers with an "18" on the front but never a "4". I have asked the seller to get a picture of the engine plate.
