I was in need of a GOOD mower to cut my Florida St. Augustine lawn - 1/4 acre. My internet search on the JD website stated "Cast iron cylinder liner" for the JS20, JS30 and the JS40 mowers. Went to my local Lowes and bought the JS40. Mulching was pretty good as I have NO intention in emptying a bag every two "swipes". I was bit apprehensive about the claim of the cast iron liner on this mower, especially for the $500. it cost. E-mail with B&S told me flat out that the engine was an 875 Series with a "standard aluminum bore". Talk about being P.O'd.... After repeatedley being told by JD that my JS40 had the liner, they informed me several days later that they have a "website problem" and the mower DID NOT have the liner. As this mower is also offered for sale "Online", can you say "INTERNET MAIL FRAUD?"... I have registered a complaint with the Florida and Illinois Atty. General about this very deceptive trade practice and will keep you'all informed. Even after almost TWO WEEKS, they are STILL advertising this line - the JS20,30, and 40 with the cast iron cylinder liner. (Go to their site and SEE FOR YOURSELVES).. I returned my JS40 to Lowes and told them of this "mis-representation" and told them it wasn't their fault, but JD's in their ad. Finally bought a TORO 20057 at a local business - LOVE IT... A REAL engine - Intek PRO, Cast iron liner, Mulches like a blender, NO grass left behind at all, AND the best benefit ever, an oil filter... I figure that over a MINIMUN 10 year life, my pro-rated cost is only $65./Year vs the $50./Year with most any other mower. The TORO "Personal Pace" system is the nuts. Goes just as fast, or as slow as you need to, although even with a good summers grass growth, the engine doesn't slow AT ALL. If you buy, you WILL be pleased..
