My main mower is my 2002 48 inch Exmark Turf Tracer HP walk behind with a stand-on velke/sulky. I only have a couple of lawns that I don't use it on at all. Most lawns I at least cut in around the edges and obstacles and mow the steep slopes with it and I mow the entire lawn for smaller lawns, say under 1/2 acre. I reserve the Z turns for large area mowing and when I have to bag.
