Deck Spindle Assembly Replaces for Toro 117-7267 &117-7439,117-7268, SS5000 SS4200 4235 4260, Timecutter 121-0751, for Stens 285-923 Lawn Mower Spindle Replacement

What It Is

This deck spindle assembly transfers power from the mower’s belt to spin the blade, essential for cutting grass. It’s designed for Toro TimeCutter and SS series zero-turn mowers, plus select Craftsman, Husqvarna, and John Deere decks that use the same OEM pattern.

Fitment & Compatibility

Measure your deck’s spindle-to-spindle bolt pattern (center to center) and the spindle shaft diameter. This unit fits decks with a 3.5” bolt circle and a 5/8” shaft. Direct OEM replacements: Toro 117-7267, 117-7268, 117-7439, and 121-0751. Also compatible with Stens 285-923, but not with Toro models using a 4.0” bolt circle or 1” shaft. Check your deck’s model number (e.g., SS5000, SS4200, 4235, 4260) or measure the existing spindle before ordering. Aftermarket—not genuine Toro—so verify dimensions if your deck is older or modified.

Key Things to Know

• Build quality: Metal housing with sealed ball bearings—good for residential use, but may wear faster than OEM under heavy commercial duty.
• Installation: Moderate difficulty; you’ll need a socket set, torque wrench, and possibly a puller for stubborn spindles. Expect 30–60 minutes per spindle.
• Common gotcha: The pulley bolt is reverse-thread on some Toro decks; check your manual before tightening.
• Bearing noise: If you hear grinding after install, the spindle housing may be slightly warped—return and exchange rather than forcing it.

Should You Buy It

If you own a Toro TimeCutter or SS series and need a budget-friendly replacement for one or two spindles, this is a solid value. Skip it for commercial-grade decks or if you want genuine Toro warranty support—go OEM instead. For DIY homeowners, it’s hard to beat at this price with a 4.5-star average.
