Spindle Assembly for John Deere LA D Series Mower D100 D110 D130 E100 E100 GY20867 GY20962 GY21098 GY20454 with Nut Bolts 332513B Pulley

What It Is

This spindle assembly is the rotating hub that drives the mower blade on John Deere LA, D100, D110, D130, E100, and E130 series lawn tractors. It replaces worn or seized spindles that cause blade wobble, vibration, or cutting deck failure.

Fitment & Compatibility

Before buying, confirm your deck size (42", 48", or 54") and check your current spindle’s OEM part number. This assembly fits models using GY20867, GY20962, GY21098, or GY20454 spindles—common on 100-series and LA-series tractors with Edge or Accel Deep decks. It includes the pulley, nut, and bolts (OEM-style 332513B), but measure the pulley diameter (typically 3.5") and spindle shaft length to match your deck. Aftermarket part; not a genuine John Deere OEM. Verify your deck’s spindle bolt pattern (usually 3-bolt) and shaft diameter (usually 5/8").

Key Things to Know

• Quality is mixed: some users report bearings failing after one season, especially with heavy or wet grass. Grease fittings are absent—these are sealed bearings, so no maintenance possible.
• Installation is straightforward: remove the old spindle, transfer the pulley, and bolt the new one in. Torque the spindle nut to 30–40 ft-lbs; over-tightening can warp the housing.
• The included pulley may not match your original’s groove depth or belt alignment. Compare side-by-side before installing; if misaligned, reuse your old pulley.
• Check for warped deck mounting holes—common on older Deeres—which can cause premature spindle wear. Use lock washers or threadlocker.

Should You Buy It

Buy this if you need a low-cost, quick replacement for a lawn tractor spindle and your deck is in good shape. It’s a decent budget option for DIY homeowners, but if you mow heavy grass or want longer life, spend more on a genuine John Deere or heavy-duty aftermarket spindle with serviceable bearings.
