GELASKA 3 Pack 139-3214 Spindle Assembly with 125-5575 Pulley 119-8820 Belt Replaces 121-0751, 117-7267, 117-7439 for Toro Timecutter Mx5000 Mx5025 Mx5050 MX5060 SS5000 SS5035 SS5060 Zs5000 Mowers

What It Is

This 3-pack spindle assembly kit, complete with pulleys and a belt, is designed to replace the original spindles on select Toro TimeCutter and ZS series zero-turn mowers. It handles the blade rotation and deck drive for residential mowing on medium to large lawns.

Fitment & Compatibility

Before buying, verify your mower’s model number from the data tag under the seat. This kit fits Toro TimeCutter models MX5000, MX5025, MX5050, MX5060, SS5000, SS5035, SS5060, and ZS5000. It replaces OEM spindles 121-0751, 117-7267, and 117-7439, and includes the 125-5575 pulley and 119-8820 belt. Check deck size – these models typically have 50- or 60-inch decks, but confirm your deck’s spindle bolt pattern (usually 3-bolt) matches the assembly. Aftermarket, not OEM – measure your existing spindle shaft diameter (common 5/8” or 3/4”) to ensure alignment with the included pulley.

Key Things to Know

• Quality vs OEM: These are aftermarket spindles, generally durable for homeowner use but may not match OEM longevity under heavy commercial duty. Grease fittings are included for periodic maintenance.
• Installation difficulty: Moderate. Requires basic tools (socket set, jack to lift deck, possibly a puller for stubborn spindles). Expect 1-2 hours for all three.
• Common gotcha: The belt included may be slightly shorter or longer than stock; check tension after installation. If the belt is too tight, it can strain the pulleys. Also, ensure the spindle housing bolts are torqued to spec (typically 30-40 ft-lbs) to prevent wobble.
• Warranty: Usually 90-day to 1-year from GELASKA – keep proof of purchase for any defect claims.

Should You Buy It

If you own one of the listed Toro TimeCutter or ZS models and need a cost-effective spindle replacement for home use, this kit is a solid value. It saves money over buying three OEM assemblies and includes the belt and pulleys. Avoid it if you have a different deck size or model, or if you require commercial-grade durability for daily heavy mowing.
