I'm hoping some of you vets out there can give me some solid pointers. I am looking for a walk behind that will fit the following needs the best: MULCHING and fitting thru fence gates. Obviously this would put me in the 32"-36" category and, obviously, I want to be as efficient as possible. I have a local Exmark, Toro, Snapper and Gravely dealers. I am also intrigued by the Quick 36 Sami. any thoughts????
