I have run walker mowers for nine years and am finding that as properties get bigger I need something faster and able to cut without bagging. I have tried side discharge decks for the walkers, but they leave visable windrows of grass, especially in thick damp grass or leaves. My question is what have you found to be the best Z mowers for cut and overall reliability? I am looking for a 52" Z, so whats the best, Scag Turf Tiger - BobcatZT-200 - Toro Z master - Exmark - etc.?
