Looking at the 54" Lesco Z two. The price seems very good @ $6295.00 but how is the quailty of this machine. I have Lesco w/b mowers now and have had very few problems and they give a great cut. Can you get stripping kits and mulch kits for the Z two. How good is the collection system they put on these machines (PeCo system). How do they cut in tall grass. Any help is appreciated.
