Which would one be happier with when it comes to handling leaves, the Exmark Navigator or the Lazer Z with the 2 bag ultravac (I think that's all that'll fit on a 48" model)? Does either have a distinct advantage in the areas of blowout, suction, leaf reduction, ease of dumping, or capacity? I think the Navigator would fit in more places due to not having an impeller slung on one side, and I do some undulating areas where I wonder if it might get knocked around. For regular mowing each has pros/cons with me. I don't care about top speed. The availability of the 42" deck on the Navigator is a plus for me. But I like the ability to use a foot pedal to raise/lower the deck with the Lazer. I assume the Navigator can't do that. Doing small/medium properties, and I'd mulch anything huge anyway. Budget not a huge issue, first new mower in 7 years.
