Powtol GY20573 Air Filter for John DeerLA115 LA105 L100 Z225 LA110 115 L108 LA100 105 L105 108 L107 Lawn Tractor with AM125424 Oil Filter

What It Is

This is an aftermarket air filter and oil filter combo kit designed to replace the OEM air filter (AM125424) and oil filter on select John Deere 100-series lawn tractors. It’s for routine engine maintenance—keeping dust out of the carburetor and contaminants out of the oil.

Fitment & Compatibility

Before buying, confirm:

• Lawn tractor models: Fits John Deere LA105, LA115, LA110, L100, L108, LA100, 105, 115, L105, L108, L107, Z225, and others using the AM125424 air filter.
• Engine type: Works with Briggs & Stratton single-cylinder engines (common in these Deere models). Not for Kohler or Kawasaki engines unless they share the same filter part number.
• OEM reference: The air filter replaces John Deere part AM125424, AM125424A. The oil filter is a generic replacement—check your owner’s manual for the exact oil filter thread size (usually 3/4”-16 or 13/16”-16) and bypass valve specs.
• Physical check: Measure the air filter’s outer diameter (approx. 4.5”) and height (approx. 2.5”). Oil filter is roughly 3” tall with a 1” thread. If your deck size is 42” or 48”, this kit should still fit; deck size doesn’t affect filter compatibility.

Key Things to Know

• Quality: Buyers report the air filter seals well and the oil filter has a proper anti-drainback valve. Not OEM-grade paper but fine for standard residential mowing. Some note the foam pre-filter is thinner than OEM.
• Installation: Both filters are drop-in replacements. No tools needed for the air filter (just a clip or wing nut). The oil filter requires a filter wrench and a drain pan. Torque to about 12-15 ft-lbs hand-tight.
• Common gotcha: The oil filter may not have the same bypass valve pressure as genuine John Deere filters—if you mow in heavy dust or extreme heat, consider OEM for peace of mind. Also, check that the air filter’s gasket matches your housing (some users had to trim the foam slightly).
• Value: At $15.99 for two filters, it’s cheaper than buying OEM separately (often $10-12 each). But you get what you pay for—expect shorter service intervals (replace air filter every 25 hours vs. 50 with OEM).

Should You Buy It

If you own a compatible John Deere 100-series lawn tractor and want a budget-friendly, fast replacement for routine maintenance, this kit works well for light residential use. Skip it if you mow in heavy dust, need exact OEM specs, or prefer longer filter life—stick with genuine John Deere filters instead.
