how long have you had it. I purchased one last year in April 2009 and there are several issues with this mower. 1. the rear wheel covers keep falling off. If you don't pay attention, you will suck one up into your rear bag which i've done. I took the damaged cover to my local sears store and they gave me a new one. 2. It seems the battery holds enough charge for one key start. pull start there after even after Sears replaced the batterry. 3. the pull start used to be easy 1 to 2 pulls but soon after that, it takes sometimes 10 pulls or more where I strained my shoulder muscles. I took it in for service and took it home after 2 weeks. for this years new mowing season beginning (last week) the mower started (key) only in the beginning and pull there after. I now use a velcroe strap to keep the motor running. I was on my last bag and the front wheel fell off which i only noticed after the mower ran over it. the plastic bell housing under the mower towards the rear is plastic so when you're backing up and it gets caught on some grass it flexes and the blade hits it to shreads. I took the mower back for service yesterday 4/19/10. This is my 3 Craftsman professional in less than a year. The first leaked lots of oil., the second just refused to start. I had though that the 3rd one would be a charm but this design has very serious flaw. Not deserving of the Professional name.
Your's truly,
A very disappointed long time sears customer.
P.S. Sears, please look into your quality control standards and maybe consider upping your standards a bit. I'll pay a bit more for a product for quality.
