AM125424 Oil Filter Compatible with John Deere D100 D105 D110 D120 D125 D130 D140 D150 D155 D160 D170 Lawn Mower Oil Filter, Replace# GY20577, 696854, 49065-0721, 49065-7007 Oil Filter (4 Pack)

What It Is

The AM125424 is a spin-on oil filter designed for select John Deere lawn tractors with 100- and 200-series models. It removes contaminants from engine oil during operation, and this 4-pack provides multiple filter changes at a low per-unit cost.

Fitment & Compatibility

• Fits John Deere models: D100, D105, D110, D120, D125, D130, D140, D150, D155, D160, D170. Also fits many LA-series and X300/X500 models with the same filter thread and bypass specs.
• OEM cross-references: Replaces John Deere GY20577, plus 696854, 49065-0721, and 49065-7007. Check your owner’s manual or current filter for these numbers.
• Measurements: Thread size is 3/4″-16 (SAE standard). Overall height is about 3.25″; outside diameter is 2.75″. Measure clearance around your engine to ensure it fits without rubbing.
• What to verify: Confirm your engine is a Briggs & Stratton or Kawasaki single-cylinder (most common on these Deeres). If you have a Kohler Courage or a twin-cylinder, this filter may still fit, but double-check the thread and bypass valve rating.

Key Things to Know

• Quality: These are aftermarket filters, not OEM. They meet or exceed OEM specs for filtration and burst strength for residential use, but may not have the same anti-drainback valve durability as premium brands.
• Installation: Easy – hand-tighten until the gasket contacts the mounting base, then give another 3/4 turn. No tools required. Drain oil first.
• Common gotcha: Some users report the filter can be slightly taller than OEM. Make sure it doesn’t hit the frame or deck when the engine is running.
• Value: At ~$5 per filter (4-pack), it’s a solid deal for regular oil changes. Buying singles at a dealer costs $10–15 each.

Should You Buy It

If you own one of the listed John Deere models and want a budget-friendly, reliable filter for routine oil changes, this 4-pack is a smart buy. It’s not for heavy commercial use or engines requiring a specific OEM-only filter, but for home lawn mowing, it works great.
