I noticed that the discharge opening on my super mini is rectangular where my Super Z has a 45 degree cut out on the tail end of the opening. Did they test the Mini with the 45 degree cut out and not find it suitable? One of my workers thought with the factory blades the clippings were being driven to the back of the cut out and stacking up against the back inside of the deck about where the 45 cut out would be if it were there. It was damp today, and it was clumping badly. Seemed everytime the mower came to the end of a pass to turn it dumped green mashed potatos is large clots. I wondered if testing was done and what reasons were motivation to change the deck from the Super Z style witht he 45 cut out. I feel my Super Z performed better in similar conditions, and has been improved by cutting the opening out to match the 05 deck design. Would their be similar benifits in opening up the hole on the Mini in a similar manner? Any thoughts and help would be great.
