12 050 01-S Oil Filter Replacement for Kohler Engine Lawn Mower Tractor, Cub Cadet, Craftsman, Troy Bilt, Toro, Gravely, Part No. - 12 050 01-S1, KH-12-050-01, 12-050-08, KH-12-050-08 1 Pack

What It Is

This is a replacement oil filter designed for Kohler engines commonly found in lawn tractors from Cub Cadet, Craftsman, Troy-Bilt, Toro, and Gravely. It filters engine oil to trap debris and contaminants, protecting the engine during operation.

Fitment & Compatibility

Before buying, check your engine model number (stamped on the valve cover or engine shroud) – this filter fits most Kohler Courage, Command, and Pro series engines, including models with part numbers 12 050 01-S1, KH-12-050-01, 12-050-08, and KH-12-050-08. It is an OEM-equivalent replacement, not a genuine Kohler part, but matches the same thread size (3/4-16) and gasket dimensions. Verify your existing filter’s part number or measure the thread diameter and gasket outer diameter (approx. 2.5 inches). Does not fit Briggs & Stratton or Kawasaki engines.

Key Things to Know

• Quality: Made by Cub Cadet (under MTD), meets or exceeds OEM specs. Users report no leaks or fit issues.
• Installation: Easy – hand-tighten until gasket contacts, then 3/4 turn more. No tools needed, but a filter wrench helps if stuck.
• Common gotcha: Some Kohler engines use a different thread (M20x1.5) on older models – double-check your engine’s part number to avoid mismatch.
• Replacement interval: Change every 100 hours or annually, whichever comes first. Always replace the oil too.

Should You Buy It

If you own a lawn tractor with a Kohler engine from the brands listed and need a reliable, affordable filter, this is a solid choice. It’s priced competitively, fits most common models, and has strong user reviews. Not for those with non-Kohler engines or who insist on genuine Kohler-branded parts.
