Carburetor Shut Off Valve For Cub Cadet Ultima ZT1 ZT2 RZT50 For John Deere X380 X320 X324 For Kawasaki FR691V FS691V FR730V FS730V For Husqvarna Z254F For Toro SS-5000 SS-5050

What It Is

A replacement carburetor shut-off valve that stops fuel flow to the carburetor when the engine is off, preventing flooding and leaks. Designed for zero-turn mowers and garden tractors with Kawasaki FR/FS V-twin engines.

Fitment & Compatibility

• Direct fit for: Cub Cadet Ultima ZT1, ZT2, RZT50; John Deere X380, X320, X324; Husqvarna Z254F; Toro SS-5000, SS-5050.
• Engine compatibility: Kawasaki FR691V, FS691V, FR730V, FS730V only. Does not fit Kohler, Briggs & Stratton, or other engine brands.
• Check before buying: Measure the fuel line inside diameter (typically 1/4” or 5/16”). Verify the valve’s barb size matches your hose. Confirm you need a shut-off valve (some models have an inline fuel filter instead). OEM part numbers vary; this is an aftermarket replacement—compare visually to your old valve.

Key Things to Know

• Quality: Aftermarket part. One review at 4.0 stars—limited feedback. Expect basic plastic/metal construction; may not match OEM durability.
• Installation: Easy, 10-minute swap. Disconnect fuel line, remove old valve, install new one (use fuel-resistant clamps if not included). No special tools required.
• Gotchas: Valve may be slightly larger than OEM—check clearance near the carburetor. Fuel line may need trimming if the valve is longer. Ensure the valve is fully closed (lever perpendicular to fuel flow) before storage.
• Common issue: Some users report the lever feels loose or the valve leaks after a season; inspect periodically.

Should You Buy It

Buy this if you need a quick, budget-friendly fix for a failed shut-off valve on a Kawasaki-powered Cub Cadet, John Deere, Husqvarna, or Toro mower. It’s fine for occasional use but may not last as long as an OEM valve. If you want maximum reliability or have a commercial mower, stick with the manufacturer’s part.
