117-7439 Spindle Assembly Compatible with Toro TimeCutter 42" 50" 5000 5060 4225 4235 4250, Ex Mark Quest 50" Deck Lawn Mower, Replace 117-7268 117-7267

What It Is

The 117-7439 spindle assembly is the rotating hub that drives your mower blades. It’s designed to replace worn or failed spindles on Toro TimeCutter zero-turn mowers with 42" or 50" decks and Ex Mark Quest 50" deck models.

Fitment & Compatibility

• Deck size: Fits Toro TimeCutter 42" (models 4225, 4235, 4250) and 50" (models 5000, 5060) decks. Also fits Ex Mark Quest 50" decks.
• OEM cross-references: Replaces Toro OEM part numbers 117-7268 and 117-7267. This is an aftermarket part, not OEM Toro.
• Measure before buying: Confirm your spindle bolt pattern is 3.25" center-to-center and the shaft diameter is 5/8". Measure the overall height (approx. 4.5") and bearing housing diameter (approx. 2.5").
• Check blade compatibility: This spindle uses a 5/8" shaft with a 5/16"-24 threaded tip. Ensure your blades match.
• Verify your model number: Double-check your mower’s model number (e.g., 747xx, 748xx) on the frame tag. Some TimeCutter variations use different spindles.

Key Things to Know

• Quality: Aftermarket part, not OEM. Most users report it works fine, but some note bearings may not last as long as genuine Toro. Grease before install.
• Installation difficulty: Moderate. Requires removing the deck, belt, and blade. You’ll need a socket set, torque wrench (blade nut to 45-55 ft-lbs), and possibly a puller for stubborn spindles.
• Common gotchas: The spindle housing may be slightly taller than OEM—check blade clearance under the deck. Use thread locker on the blade bolt. Don’t overtighten the spindle mounting bolts (20-25 ft-lbs).
• Kit includes: Spindle assembly with bearings and shaft, but no mounting bolts or blade. Reuse your existing hardware.

Should You Buy It

This is a solid budget-friendly replacement if your original Toro spindle is worn (noisy, wobbling, or seized). It’s right for DIYers who want to save money over OEM ($30–40) and don’t need commercial-grade longevity. Skip it if you run a landscaping business or want maximum durability—stick with genuine Toro.
