ATRACYPART Mower Deck Spindle Assembly Fit for Exmark,Fit for Toro Quest 42" 48" 52" Cut- Replaces OEM 116-5712, 116-3497, 109-8744, 109-6394, Lawn Mower Replacement Part

What It Is

This is a mower deck spindle assembly that drives the blades on Exmark and Toro Quest 42", 48", and 52" cutting decks. It replaces worn bearings or bent housings that cause blade wobble, uneven cuts, or vibration.

Fitment & Compatibility

Before buying, confirm your mower’s deck size (42", 48", or 52") and model series—this fits Toro Quest models (e.g., 74242, 74248, 74252) and certain Exmark zero-turn mowers using the listed OEM numbers. The part replaces OEM 116-5712, 116-3497, 109-8744, and 109-6394. Measure your existing spindle’s bolt pattern (typically 3-bolt, 3.5" center-to-center) and shaft diameter (usually 5/8" or 3/4"). This is an aftermarket part, not OEM Toro, so check that your deck uses a standard spindle housing without proprietary mounting.

Key Things to Know

• Quality: At $47.99, it’s cheaper than OEM ($80+). Reviews (4.4 stars, 15 ratings) suggest decent bearings, but some report shorter lifespan than OEM under heavy use.
• Installation: Moderate difficulty—requires removing the deck, belt, blades, and old spindle. Use a puller if the old spindle is seized. Torque bolts to 30-40 ft-lbs.
• Common gotcha: Verify the pulley size matches your original (often 3.5" or 4" OD). The included pulley may not fit all belt configurations.
• Warranty: Usually 90 days to 1 year from ATRACYPART—check before buying. No OEM support.

Should You Buy It

Buy this if you need a budget-friendly replacement for a single spindle on a Toro Quest or compatible Exmark deck and you’re comfortable with moderate DIY work. Skip it if you want OEM durability for commercial-grade mowing or have a non-standard deck.
