Cub Cadet mowers last a long time if cared for properly. Sometimes, they last long enough that you will wear out the seat on your tractor before you're ready for a new mower. Thankfully purchasing and installing a new seat is a simple upgrade. It is also an upgrade that can make your hours of mowing much more comfortable.
If your cub cadet seat is starting to show some wear, you can also buy a cover for it that will increase it's life and also increase your comfort.
