What It Is

The AM108925 spindle assembly is the blade-mounting hub and bearing unit for John Deere 38-inch mower decks on select lawn tractors. It supports and spins the cutting blade, and this 2-pack replaces worn or failed spindles on residential Deere models.

Fitment & Compatibility

Before buying, confirm your deck is a 38-inch model. This spindle fits John Deere 111H, 112L, 116H, 160, 165, 170, 175, 240, LX172, and LX288 tractors. It directly replaces OEM part numbers AM103502 and AM107590. Measure the spindle shaft diameter (typically 5/8-inch) and bolt pattern (3-bolt, 3-inch center-to-center) to verify. This is an aftermarket part, not OEM, but matches original dimensions. Check your deck’s spindle housing for cracks or wear before installing.

Key Things to Know

• Quality vs OEM: Aftermarket spindles often use sealed bearings that are comparable to Deere originals, but may have slightly shorter lifespan under heavy use. Inspect bearings for smooth rotation before installation.
• Installation difficulty: Moderate – requires removing the deck, blade, belt, and pulley. You’ll need a socket set, wrench, and possibly a puller for the pulley. Allow 1–2 hours per spindle.
• Common gotcha: The pulley nut may be seized. Use penetrating oil and heat if needed. Torque the new spindle’s pulley nut to 30–40 ft-lbs to avoid wobble.
• Deck alignment: After replacement, check blade tip height and level the deck to prevent uneven cutting.

Should You Buy It

If your 38-inch Deere deck has a noisy or wobbly spindle, this 2-pack is a cost-effective fix for DIY homeowners. It’s not built for commercial mowing, but for residential use it offers reliable performance at half the price of OEM. Skip it if you need heavy-duty spindles for a zero-turn or high-hour commercial deck.
