ACEBRI GY20454 GY21098 GY20867 GY20962 AUC15811 Spindle Assembly Fits 42" 48" Deck for John Deer LA110 LA115 LA100 LA120 LA125 LA145 LA105 D110 D130 D125 D140 E140 E130 2 Pack

What It Is

This ACEBRI spindle assembly kit replaces the rotating hub that drives your mower blades. Designed for 42" and 48" John Deere decks, it’s a direct-fit aftermarket part for dozens of models including LA, D, and E series tractors.

Fitment & Compatibility

Before buying, confirm your deck size (42" or 48") and model number—it fits LA100–LA145, D110–D140, E130–E140, and several others (full list in title). This replaces OEM part numbers GY20454, GY21098, GY20867, GY20962, and AUC15811. Measure your existing spindle’s shaft diameter and bolt pattern (typically 3-bolt, 3.5" center-to-center). Not compatible with stamped-steel decks or older 38" mowers.

Key Things to Know

• Quality vs OEM: ACEBRI spindles are budget-priced; bearings may wear faster than factory John Deere parts. Grease them before install and after every 10 hours.
• Installation difficulty: Moderate. You’ll need a jack, socket set, and possibly a puller for stubborn spindles. Expect 30–60 minutes per spindle.
• Common gotcha: The 2-pack includes two identical spindles—verify your deck uses two (most 42" and 48" decks do). Don’t mix with other brands; bolt holes may not align.
• No hardware included: You’ll need your original bolts, washers, and lock nuts. Inspect for rust before reuse.

Should You Buy It

Right for budget-conscious DIYers who need a quick fix for a worn spindle on a standard 42" or 48" John Deere deck. Skip if you want OEM longevity or own a commercial zero-turn—the bearings won’t hold up to heavy daily use.
