Toro 136-7848 Oil Filter Replaces 120-4276, Compatible with Lawn Mower

What It Is

The Toro 136-7848 is a genuine OEM oil filter designed for Toro lawn mowers, specifically replacing the older 120-4276 filter. It removes contaminants from engine oil to protect critical components during operation, suitable for residential and commercial mowers.

Fitment & Compatibility

• Check your model number: This filter fits Toro TimeCutter, Titan, and Z-Master zero-turn models with Kawasaki or Toro engines. Not for Briggs & Stratton or Kohler engines.
• Verify thread size: The 136-7848 uses a 3/4"-16 thread (common SAE standard). Measure your old filter’s thread diameter and pitch if unsure.
• Cross-reference OEM numbers: It replaces Toro 120-4276 and also fits Kawasaki 49065-0721. If your mower calls for one of these, this works.
• Measure overall length: This filter is about 3.5 inches long. Ensure clearance in your engine compartment, especially on tight-frame mowers.
• Not universal: Does not fit push mowers or older Toro models with different oil filter mounts.

Key Things to Know

• Quality: Genuine Toro part with anti-drain back valve and high-flow media – better than many aftermarket filters for preventing dry starts.
• Installation difficulty: Easy – spin off old filter, lubricate gasket, hand-tighten to 2/3 turn after contact. No tools needed.
• Gotcha: Some aftermarket filters (e.g., Fram) may fit but can cause lower oil pressure. Stick with OEM for warranty or critical use.
• Maintenance tip: Replace every 50 hours or annually, whichever comes first. Always change oil at same time.

Should You Buy It

If you own a Toro zero-turn with a Kawasaki or Toro engine, this is the correct OEM filter – buy it for reliable filtration and peace of mind. For other brands or older models, verify fitment first; otherwise, a quality aftermarket alternative may work.
