Answer
 Hello James:

 Check the Battery for a Bad/Weak Cell. Check the Starter for Dragging. The Voltage should Never Drop Below 9VDC. Anything Below that and the Brushes inside the Starter Burn from Low Voltage. To Get Better Service Out of my Mowers; I Use a Larger Battery Cable than the Ones Installed by the Manufacturer. I Install the Largest CCA Battery that will Fit the Mower Safely. The Larger Battery Cables Allows More Current Flow to the Starter and Decreases the Starter Problems. I have One Mower that has had the Same Starter for 14 Years and Never a Starter Problem; Just the Battery having been Replaced a Few Times. You Problem is Either the Battery or the Starter. Hope this Helps. Let me know what Happens, Please. Thanks.

 Good Luck

 Respectfully

 John
