1205001S Oil Filter AM125424 Fits for Kohler Engine Lawn Mower John Deere MTD Cub Cadet Craftsman Toro Husqvarna Replaces 12-050-01 GY20577 (4 pcs)

What It Is

This is a set of four oil filters (part numbers 1205001S / AM125424) designed for Kohler engines found in lawn tractors and zero-turn mowers from John Deere, MTD, Cub Cadet, Craftsman, Toro, and Husqvarna. It replaces OEM filters 12-050-01 and GY20577.

Fitment & Compatibility

Before buying, verify your engine’s model – this filter fits Kohler Courage, Command, and Pro series engines (typically 15-27 HP). Check your mower’s OEM filter number against 12-050-01 or GY20577. Physically measure the filter: it’s roughly 3.25 inches tall with a 3/4-inch-16 thread. Do not assume it fits all Kohler engines – older or smaller single-cylinder engines may use a different thread size or shorter filter. Always cross-reference your mower brand (e.g., Cub Cadet XT1, John Deere D100 series) with the filter numbers listed.

Key Things to Know

• Quality: These are aftermarket filters, not OEM Kohler. They meet basic flow and filtration specs but may lack the anti-drain back valve or bypass pressure of genuine Kohler filters – fine for standard oil change intervals, not for extreme duty.
• Installation: Easy – hand-tighten only (about ¾ turn after gasket contacts). Overtightening can damage the gasket or housing. No tools needed.
• Gotcha: The included gasket size may vary slightly from OEM; always lubricate the gasket with fresh oil before install. If your engine has a shallow filter recess, these may be slightly taller than OEM – measure clearance before buying.
• Pack size: You get four filters in one box. Plan to use them within 2 years; oil filters degrade over time.

Should You Buy It

Buy this if you own multiple Kohler-equipped mowers or do frequent oil changes (e.g., heavy commercial use) and want a cost-effective bulk option. Skip it if you need a single filter for a high-hour engine or prefer OEM for warranty/performance assurance.
