I have this awesome dealer that basically sold my 18 year old walker (model c). He would tell homeowners that were wanting a Walker but not wanting the cost for a new one. It made it possible for me to buy a brand new 26 hp efi with the 48" deck SO... Today my parner and I mowed 21 lawns in 9 hours. These were lawns that would have taken us considerably longer before. They are basically a mix of sizes but a large burden to do in one day. Yesterday I mowed one in an hour and fifteen minutes that used to take both of us working together an hour (or more). This was a lawn that just strained the heck out of the old machine. The new machine didn't miss a beat I love this mower! the c had a 42" deck we went with the 48" for this one (I know why not a 60" monster???) I am just real impressed with the power, quality of cut, and speed. YEEHAW! My old machine sold for 2500.00 and the new cost 9500.00 so there is some paying to do but it is real clear that this machine will pay for itself. Dang I love those new toys!
