Jim M., Fred F., welcome!
Jim M., like Bryan wrote, the links at the top of the page will send you to forum sponsors some of which sell after market small engine parts Stens being one of those aftermarket manufacturers.
Fred F., Hy-Tran is made by CaseIH and is available at Cub Cadet and CaseIH dealers. Be sure to get the "old style" Hy-Tran not the new stuff for the newer model Cub Cadets. We have one forum member (Richard C.) that lives near you (Not sure how far from Phoenix he is.) perhaps he can direct you to a local or near local supplier for both the Hy-Tran and the filter. Or the forum sponsors can also ship you what you need.
Richard, any chance you can help out Fred? TIA.
