What It Is

This is a 5-pack of aftermarket oil filters designed for Toro V-twin engines, specifically those used in TimeCutter zero-turn mowers and select Sw/Ss series models. They replace OEM filters to keep engine oil clean and protect against wear.

Fitment & Compatibility

Before buying, verify your mower’s engine model. These filters cross-reference with OEM numbers 136-7848, 120-4276, 126-5234, 127-9222, and AM107423. They fit Toro TimeCutter models like SW4200, SS4250, SS5000, and SS5425, plus other Toro mowers with Kawasaki or Toro V-twin engines (e.g., FX, FS, FH series). Check your owner’s manual or existing filter for the exact OEM number—this pack won’t fit single-cylinder or small-displacement engines. The filter thread size is 3/4"-16, and the canister diameter is about 2.7 inches; measure your old filter if unsure. These are aftermarket, not OEM Toro, but match the same specs.

Key Things to Know

  • Quality: Made by Therwen, a budget brand. Reviews are solid (4.6 stars), but some users report minor fitment variance (e.g., slightly shorter canister). Inspect the rubber gasket for a snug seal.
  • Installation: Easy—hand-tighten only (1/2 to 3/4 turn after gasket contacts). Over-tightening can strip threads or damage the gasket.
  • Common gotcha: Don’t use if your engine requires a specific anti-drainback valve or bypass valve not listed. These filters include both, but confirm with your engine manual if you have a high-hour or high-pressure system.
  • Value: $19.99 for 5 filters (~$4 each) vs. $8-12 per OEM filter. Great for multiple oil changes, but not a performance upgrade.

Should You Buy It

Buy this if you own a Toro TimeCutter or similar V-twin zero-turn mower and want an affordable, reliable oil filter for routine maintenance. It’s a solid budget alternative to OEM, but skip it if you’re particular about brand-name parts or have a non-standard engine—stick with OEM for guaranteed fit.
