Yesterday I cut 4.5 acres with a JD 653. The mower belongs to a new customer. He purchased the property and the mower came with it. The previous owners demoed several mowers for the rolling terrain. They chose the Deere. I like most Deere products. I assume that out of several mowers these folks made a good choice. Before I cut, I removed the mulch kit because I didn't like the cut I had noticed before. I started out thinking this thing is awesome (compared to my walkbehind) Then I couldn't keep grass out of the beds( alot of beds ). This thing throws big blades of grass a long way. Well I put the much kit back on. I noticed the same old ugly cut as before, even with sharp blades. Well I thought I could live with the cut but then on a very slight hill the mower took off sliding and when it slides you have very little control. This happened several times before I finished mowing I even slid into a stack rock wall. This was dry ground too! I could have cut these little slopes with an old Snapper mower. I could have used my walk behind, WITH THE VELKE, and stipped it in any direction. If all Z's are like this you can have them! Does anyone know what I can do to at least get a nicer cut? I have to cut again Friday. I would just about take a whippen than to get back on that Z.
