⚡ Quick Answer:

Lawn mower oil filter cross-reference charts match OEM part numbers to WIX, Baldwin, Donaldson, and FRAM equivalents at 40–75% savings vs dealer pricing. Most residential mowers use a 3/4″-16 thread, ~2.45″ gasket, 3.0–3.5″ height spin-on filter. Key cross-references: Husqvarna 576-89-73-01 → WIX 57035. Bad Boy 063-8017-00 → WIX 57035. Cub Cadet 490-201-C010 → WIX 57035. John Deere AM107423 → WIX 57035. Always match thread size, gasket diameter, and height — not just the brand name on the box.

OEM mower oil filters run $15–25 at the dealer. Quality aftermarket equivalents from WIX, Baldwin, Donaldson, and FRAM run $5–12 — saving 40–75% per filter. Most residential and commercial mowers use Kawasaki, Kohler, or Briggs engines that share a common 3/4″-16 thread pattern, making cross-referencing straightforward. This guide covers confirmed cross-references for Husqvarna, Bad Boy, Cub Cadet, John Deere, Scag, Exmark, Toro, Troy-Bilt, and Craftsman.

🔧 3 Specs to Match When Cross-Referencing Mower Oil Filters

Thread size — most mower engines use 3/4″-16 UNF (Kawasaki, Kohler, many Briggs). Some use M20x1.5 metric. Thread mismatch = leak or blowout
Gasket diameter — must fully overlap the sealing surface. Common mower spec: ~2.45″ OD seal ring. Wrong diameter = leak under pressure
Height — determines clearance around engine, muffler, and frame. Choose similar height to OEM unless manufacturer explicitly allows different length

Cross-Reference by Engine Brand

Most mower manufacturers don’t make their own engines — they use Kawasaki, Kohler, or Briggs & Stratton. Finding the engine brand on the valve cover label is often faster than looking up the mower OEM part number.

Kawasaki FR/FX Series — Most Commercial Zero-Turns

OEM: 49065-7007 or 49065-0721. Aftermarket: WIX 57035, Baldwin B7165, FRAM PH8170, Oregon 83-013. Thread: 3/4″-16. Used in: Husqvarna, Bad Boy, Scag, Exmark, Gravely, Ariens, John Deere Kawasaki models.

Kohler Command / Courage / 7000 Series

OEM: 12 050 01 or 12 050 08. Aftermarket: WIX 51348, Baldwin B1402, FRAM PH3614. Thread: 3/4″-16. Used in: Toro, Cub Cadet, Craftsman, Troy-Bilt, Husqvarna Kohler models, John Deere Kohler models.

Oil Filter Replacement — Best Practices

Warm engine briefly so oil flows freely, then shut off and remove key. Drain oil into a pan for proper disposal.

Loosen old filter counter-clockwise with filter wrench. Verify old gasket came off with the filter — double-stacked gaskets cause instant oil loss blowouts.

Lightly coat new filter rubber gasket with fresh engine oil. Spin on by hand until gasket contacts base, then tighten 3/4 turn. Never use an impact wrench to install.

Refill with correct oil type and volume per engine spec. Run engine and inspect filter base for leaks.

Shut engine off and recheck oil level — top off after new filter fills with oil. Change interval: every 50 hours or once per season minimum.

Quality aftermarket filters from WIX, Baldwin, and FRAM match OEM specs at 40–75% lower cost. WIX 57035 covers most Kawasaki-powered mowers. WIX 51348 covers most Kohler and Kubota engines. Always verify thread size (3/4″-16 for most), gasket diameter (~2.45″), and height match your original filter.

? Frequently Asked Questions

How do I know which oil filter fits my lawn mower?

Check the engine label on your valve cover — it shows the engine brand (Kawasaki, Kohler, Briggs) and model number. Look up the OEM filter number in your operator manual or on the existing filter. Most Kawasaki FR/FX engines use 49065-7007 or 49065-0721. Most Kohler Command/7000 engines use 12 050 01. Once you have the OEM number, match it to WIX, Baldwin, or FRAM equivalents using the tables above.

Are aftermarket mower oil filters as good as OEM?

Quality aftermarket filters from WIX, Baldwin, Donaldson, and FRAM are engineered to meet or exceed OEM specifications for burst pressure, filtration efficiency, and flow. Many OEM filters are manufactured by these same companies and relabeled with the mower brand. The key is choosing reputable brands with published specs — not generic unbranded filters with no cross-reference data. WIX and Baldwin publish full cut-sheets confirming micron ratings and dimensional specs for every filter.

What happens if I use the wrong oil filter on my mower?

Wrong thread or gasket diameter causes leaks, blowouts, or complete oil loss that destroys the engine in minutes. Even if it appears to fit, a mismatched bypass valve or incorrect micron rating runs the engine with unfiltered oil or restricted flow — both accelerate wear. A cross-reference confirming thread size, gasket diameter, and height eliminates these risks while saving money over OEM.

Are lawn mower oil filters universal?

Not exactly — but many are interchangeable within engine families. Most Kawasaki FR/FX commercial engines share the same filter spec across hundreds of mower brands. Most Kohler Command and 7000 Series engines share another. The 3/4″-16 thread dominates residential and commercial mowers, meaning one WIX 57035 covers a very wide range. But you still need to verify your specific engine model before assuming compatibility.

How often should I change my mower oil filter?

Change with every oil change — every 50 hours or at least once per season for residential mowers. Commercial operators mowing daily should change every 50 hours without exception. Dusty conditions or short-run cycles justify more frequent changes. At $5–12 per aftermarket filter, frequent replacement is inexpensive insurance against accelerated engine wear.

Can I use an automotive oil filter on my mower?

Only if a reputable cross-reference catalog explicitly lists that automotive filter for your specific engine model — not just because the thread size matches. Automotive filters may have incorrect bypass valve cracking pressure, different micron ratings, or wrong anti-drainback valve design for small engine duty. The safest approach is using a filter specifically listed for your engine in WIX, Baldwin, or FRAM’s outdoor power equipment cross-reference catalog.
