1205001S Oil Filter, Replacement for Kohler Engine Lawn Mower, for Cub Cadet, for Troy Bilt Bronco 1205001, 12 050 01-S Oil Filter 1PCS

What It Is

This is a replacement oil filter for Kohler engines commonly found on Cub Cadet and Troy Bilt Bronco lawn tractors. It removes contaminants from engine oil to extend engine life and is designed for routine oil changes.

Fitment & Compatibility

• Engine brand: Kohler only (not Briggs & Stratton, Kawasaki, or Honda).
• Common models: Cub Cadet XT1, XT2, LT series; Troy Bilt Bronco (check your specific model number).
• OEM replacement: Direct swap for Kohler part 12 050 01-S and Cub Cadet part 1205001S.
• Measurements: 3.3" tall, 2.8" diameter, 3/4" thread. Cross-check with your old filter before installing.
• What to verify: Look up your mower’s engine model number (stamped on the valve cover or blower housing). If your engine uses a different thread pitch or bypass valve (rare on Kohler singles), this won’t fit.

Key Things to Know

• Quality: OEM-grade filtration, not a cheap aftermarket knockoff. Rated for 100+ hours of use.
• Installation: Hand-tighten only (1/2 to 3/4 turn after gasket contacts the mounting base). Overtightening can crack the housing.
• Common gotcha: Some Kohler Courage engines use a smaller filter (like 12 050 01-S1). Double-check your engine’s parts list—this one fits most Command, Courage, and Pro models but not all.
• Pre-oil the gasket: Lightly coat the rubber seal with fresh oil before installing to prevent leaks and ensure a good seal.

Should You Buy It

Yes, if you have a Kohler-powered Cub Cadet or Troy Bilt Bronco with a standard 3/4" thread filter. It’s a reliable OEM-spec replacement at a fair price. Skip it if your engine uses a different filter size (e.g., smaller Kohler models) or if you need a non-Kohler filter.
