Brought this Craftmen 37653 on July 13, 2008 after using four times and having the machine for one month the starter did not work any longer, I check the key if its open and the safety switch all ok. I knew the battery were in the rear botton left compartment I took the cover off, to my suprise the compartment was filled with wet grass clipping (compost, Manure) with the battery clip turn green and the acid ate the red clip and broke-off. The battery are not an a water proof compartment but just set there bare after each cut I used the water fitting to rinse the botton as told in the manual....
