What It Is

This is a set of two replacement lawn mower blade assemblies designed for select John Deere lawn tractors and zero-turn mowers. Each assembly includes the blade, spindle, and four tapped bolts, making it a direct bolt-on replacement for worn or damaged cutting components.

Fitment & Compatibility

Before buying, confirm your mower model and deck size. This kit fits John Deere D100-D160, D140, LA100-LA165, X110, X120, and X140 models with 42-inch or 48-inch decks (check your deck’s stamped model number). It replaces OEM part numbers GY20454, GY20867, and GY20962, and cross-references with Oregon 82-359, Raisman 80-12-041, Stens 285-851, and TSB 502-0039. Measure your existing blade assembly’s bolt pattern and spindle dimensions—these use 4 tapped bolts, so verify your mower’s spindle mount matches. Not for 54-inch or 60-inch decks.

Key Things to Know

• Quality: EGO-branded aftermarket parts are generally well-reviewed, but they are not OEM John Deere. Expect similar durability to OEM for residential use, but may wear faster under heavy commercial mowing.
• Installation: Easy for DIYers—remove old assembly, bolt on new one with included bolts. Torque bolts to manufacturer spec (typically 70-90 ft-lbs). No special tools needed beyond a socket wrench.
• Common Gotcha: Ensure your deck’s spindle shaft is clean and free of debris before installation. Stripped bolts or mismatched thread pitch can cause vibration or blade detachment. Double-check bolt length—these are tapped for standard John Deere spindles.
• Compatibility Check: Some D-series models use a different spindle design (e.g., D140 with 48-inch deck may need a different bolt pattern). Measure your old assembly’s bolt spacing (center-to-center) to avoid returns.

Should You Buy It

If you own one of the listed John Deere models and need a budget-friendly, ready-to-install blade assembly for residential mowing, this is a solid choice. It’s not for commercial-grade duty or non-John Deere decks, but for regular home use, it offers good value and easy installation.
