ATRACYPART 126-4630 Lawn Mower Deck Spindle Assembly Compatible with Exmark Radius E & S-Series 44" 48" 52" 60" Mower Decks

What It Is

The ATRACYPART 126-4630 is an aftermarket deck spindle assembly that drives the mower blades on Exmark Radius E and S-Series zero-turn mowers with 44", 48", 52", or 60" decks. It replaces the OEM spindle that supports the blade pulley and bearings, and is designed for residential or light commercial use.

Fitment & Compatibility

• Deck sizes: 44", 48", 52", 60" – but only on Exmark Radius E & S-Series models. Not for other Exmark series (Lazer, Turf Tracer, etc.) without cross-checking.
• Measure before buying: Remove your old spindle and verify the bolt pattern (typically 3-bolt, 4.25" center-to-center), shaft diameter (commonly 5/8" or 3/4"), and overall height. ATRACYPART 126-4630 uses a 3-bolt pattern with a 5/8" shaft.
• OEM equivalent: Replaces Exmark part 126-4630. If your spindle has a different OEM number, measure dimensions – many aftermarket spindles are not universal.
• Check blade compatibility: Ensure your existing blades fit the spindle shaft (usually a 5/8" hex or round hole). If blades have a different center hole size, you’ll need new blades.

Key Things to Know

• Quality: Aftermarket spindle. Expect adequate bearings and housing, but not the same durability as OEM. Fine for residential use; heavy commercial users may see shorter life.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench, and possibly a puller if the old spindle is seized. Plan 30–60 minutes per spindle.
• Common gotcha: The spindle may come with a pre-installed pulley, but check belt alignment after install. If the belt rides off-center, the pulley height may differ from OEM – shim or adjust as needed.
• Lubrication: Some aftermarket spindles are sealed and non-greasable. If your OEM spindle had a grease fitting, this one likely does not – that can shorten bearing life in dusty conditions.

Should You Buy It

If you own an Exmark Radius E or S-Series with a 44"–60" deck and need a budget-friendly replacement for a worn spindle, this is a solid pick for residential mowing. For heavy commercial use or if you want OEM-grade longevity, spend more on an Exmark genuine spindle. Measure twice before ordering to avoid a return.
