I have always liked the MX models. Because of the deck seat is better now. They last I got one that I got in 2011. Still going but I was using it commercially. I did replace the deck but if using personally would last longer.
Check drive belt routing I changed mine and thought I had the routing right but it would not move. Fans and all worked but no motion. Checked belt routing and it was wrong. Mower took off after routing belt right.
