I have a 3320, Im looking at used brooms and blowers. To me the 26 broom looks the same as the 60HD broom and the 59 snowblower looks unchanged other than the mounting on both. Am I wrong? Also is there a bundle number for all the attaching mounts for the broom (mounting frame , cyl, and other parts? Adding each part up individually to make work with the 3x20 hitch doesnt seem cost effective.
