I'm in the market for a Lazer Z HP for my residence. The property is 1+ acres and wooded. Mowing time is now about 75 minutes with a Honda 4514 and a 42" deck. Leaf removal in the fall keeps me on the Honda for about 3 hours including sweeping. I'm about to purchase a new eXmark HP with the 23hp Kawasaki, 52" deck and 2 bag vac. Will I need more hp to easily suck up the leaves? Should I wait for the 2005 models? Thanks.
