Why does my Cub Cadet LTX1046KW engine idle rough?

If your Cub Cadet Lawn Mower engine idles roughly, the spark plugs may be fouled, faulty, or have a gap that is too wide. Replace the spark plugs and set the correct gap. A dirty air cleaner can also cause this issue; replace the air cleaner element and/or clean the pre-cleaner.
