Help! Whats the difference between the bagger for 52 SMZ that is on the Hustler web site part number #927665, and the Humboldt bagger for SMZ, http://www.grasscatchersusa.com/product_info/hustler_rear.asp ,other than price? Is this bagger system made by Hustler or is it out sourced? The only visible difference I can see is the hose/chute and hard shell over the bags. My friend has a SZ/52 with vertical blower (the big sucker, vertical) and Humboldt bagger system. We were told this blower is made by hustler. Whats the deal? Whats hustler and whats not?
