Thanks to all who assisted. I appreciate it. And I'm sorry for misstating the model as XT725. I conflated the Cub Cadet model XT1 with the Kohler KT725. It's not as difficult to do as you may think.
I'm about to change the fuel filter on my Cub Cadet mower with a Kohler XT 725 engine. I'm finding fuel filters with micron ratings from 15 to 75. What micron rating should I look for?
