I recently retired, moved from the city to a small town in southeast Missouri. We have a much bigger yard now so I got a good but used Snapper rear engine rider. I am starting to get familiar with it but still have a long ways to go. When I bought it the 10hp motor had a broken rod so I bought a replacement 11.5hp motor from a small engine repair guy in a town not far away. I swapped the motor out and have been mowing every week since then. I'm not a mechanic at all but these thing interest me so I try to at least look at a problem to see if I can handle it, and if I can't then I have a couple of mower shops and a Snapper dealer here also.
