1. Home & Family I bought a yt 4000 6 months ago with a 1 yr warranty, when I call about a bad battery, they tell me that part is only covered for 90 days! Way to go SEARS. Guess you are another LOUSY COMPANY not worth dealing with. Guess CRAFTSMAN'S WARRANTY IS WORTHLESS ALSO NOW!!! Last time I PAY EXTRA FOR A CRAFTSMAN.
