What It Is

This is a replacement fuel cap designed for commercial and residential zero-turn and walk-behind mowers with a standard 2-inch threaded filler neck. It fits Ferris, Ariens, and Cub Cadet models, including the Ferris 48”, 52”, and 61” Hydro walk-behind dual-drive units, Ariens Zoom XL, 34Z, and 144Z, and Cub Cadet 2000 series mowers.

Fitment & Compatibility

Before buying, confirm your mower’s fuel tank neck is 2 inches in diameter and has standard threading—this cap won’t fit metric or fine-thread necks. Check your model number against the list: Cub Cadet 2000 series (OEM #1715917, 1715917SM, 5022158, 5022158SM, 539106188) and Ferris/Ariens models listed above. This is an aftermarket Stens cap, not OEM, but it’s a direct replacement with no modifications needed. If you have a different brand or older model, measure the filler neck opening to verify compatibility.
