I have a 36" Mini Z (now the FastTrack SuperDuty) that is 7 years old. Great unit, but it is time to stop repairing and replace it. My only complaint is this: the left side of the deck is smaller, with a shorter blade. This side clogs with grass almost immediately when mowing thick or wet grass. I was wondering if the 42" would be less succeptable to this since it has a symmetrical deck and both blades are the same size. If anyone has the 42", any input would be greatly appreciated.
