52 Inch Mower Deck Rebuild Fit for Ariens Ikon XL 52 Ikon-X 52CE Edge 52 Ikon-XD 52 Gravely ZTX 52 ZT XL 52 ZTX 52 Lawn Mower Includes 3 Spindles 51528000 3 Blades 04771200

What It Is

This is a complete 52-inch mower deck rebuild kit for select Ariens and Gravely zero-turn mowers. It includes three spindle assemblies (part #51528000) and three blades (part #04771200) to replace worn-out cutting decks.

Fitment & Compatibility

• Exact models: Ariens Ikon XL 52, Ikon-X 52CE, Edge 52, Ikon-XD 52; Gravely ZTX 52, ZT XL 52, ZTX 52.
• Deck size must be 52 inches—measure your deck width from blade tip to blade tip or housing edge to edge.
• OEM cross-reference: Spindles replace Ariens/Gravely #51528000; blades replace #04771200 (OEM equivalent, not genuine OEM).
• Check your deck’s mounting pattern—measure spindle bolt spacing (typically 8 inches center-to-center) and blade bolt hole diameter (usually 5/8 inch or 7/16 inch). Confirm your mower uses the same.
• Model year matters: Some 2018+ Ikon or ZTX variants may have updated spindle mounts. Compare your old spindle’s flange diameter and bolt pattern to the new ones.

Key Things to Know

• Quality vs OEM: Aftermarket spindles may use thinner bearings or lighter-duty seals. Expect 2–3 seasons of residential use; commercial operators may see faster wear.
• Installation difficulty: Moderate—requires removing the deck, swapping spindles (usually 3 bolts each), and balancing blades. You’ll need a socket set, torque wrench, and possibly a puller for seized spindles.
• Common gotcha: Spindle shafts come pre-greased, but the blade mounting bolt torque is critical (typically 70–90 ft-lbs). Overtightening can strip threads; under-tightening can cause blade wobble.
• Blades included: Standard 52-inch blades (not mulching or high-lift). If you need bagging or mulching performance, buy separate blades.

Should You Buy It

Yes, if you have a compatible 52-inch Ariens or Gravely zero-turn and need a budget-friendly refresh for a worn deck. It’s a solid value for DIY homeowners who can handle the swap—just confirm your deck’s spindle pattern and be prepared for moderate labor. Commercial users may want OEM spindles for longer life.
