Cutting my grass that is! I've got a large hilly yard. I finally got tired of wearing out box store riding mowers every 4 or 5 years so I picked up a Z411 this morning. Wow at the difference it makes, so much faster and so much smoother. I managed to mow my front yard this morning and shaved half an hour off the time it normally takes me, and I only spun myself around in a circle twice, lol
