UpStart Components Replacement for John Deere LG493537S Filter Pre-Cleaner - Compatible with John Deere 493537S Pre-Filter

What It Is

This is a replacement foam pre-cleaner element for the John Deere LG493537S and 493537S filter assemblies. It traps larger debris before it reaches the main air filter, extending engine life on riding mowers, tractors, and zero-turn equipment.

Fitment & Compatibility

• Direct OEM replacement for John Deere part numbers LG493537S and 493537S.
• Fits models including select John Deere X300, X500, X700 series, as well as 100, 200, and 300 series lawn tractors (e.g., D100, D110, D130, LA105, LA115, LA125, LA135, LA145, LA155, LA165, L100, L110, L118, L120, L130). Also fits some 7000 series tractors and Gator utility vehicles with compatible air filter housings.
• Check your existing pre-cleaner – this is the outer foam sleeve, not the inner paper filter. Measure the outer diameter (approx. 3.5 inches) and length (approx. 5.5 inches) to confirm fit.
• Not for zero-turn models with a different filter housing design (e.g., Z900 series) unless verified against OEM part numbers.
• Aftermarket vs OEM – UpStart is a third-party brand; quality is comparable, but verify your specific deck or model year if your machine has a modified air intake.

Key Things to Know

• Installation is tool-free – just slide the old foam off and press the new one over the inner filter cage. No clamps or fasteners needed.
• Washable/reusable – this foam pre-cleaner can be cleaned with mild soap and water, but replacement is recommended every 25–50 hours of operation or when it appears heavily soiled.
• Common gotcha – if your existing pre-cleaner is torn or missing, the main filter will clog faster. Replace both together for best protection.
• Low price, high value – at $4.99, it’s a cheap insurance against dirt ingestion that can damage valves and pistons.

Should You Buy It

If you own a compatible John Deere lawn tractor or Gator and want to keep your engine breathing clean air without spending OEM prices, this pre-cleaner is a solid, low-risk buy. It’s easy to install, fits standard 493537S housings, and costs less than a cup of coffee – worth grabbing as a spare or for routine filter service.
