8TEN Long Shaft Spindle for Toro 44 inch Deck Timecutter ZX440 18-44Z 80-4341 80-4380 88-4510 3 Pack

What It Is

This is a three-pack of replacement long shaft spindles for Toro Timecutter zero-turn mowers with a 44-inch fabricated deck. It supports the mower blades and houses the bearings that allow the blades to spin freely; designed for heavy residential or light commercial use.

Fitment & Compatibility

• Deck size: 44-inch fabricated deck only (not stamped decks or 42/50/54-inch models).
• Fitment: Toro Timecutter ZX440, 18-44Z, and other 44-inch deck models using OEM part numbers 80-4341, 80-4380, or 88-4510.
• Measurements: Shaft length is approximately 3.75 inches from flange to tip; spindle housing diameter is 2.5 inches. Confirm your old spindle’s shaft length—long shaft spindles are taller than standard ones.
• OEM vs aftermarket: This is a direct aftermarket replacement; verify your deck uses the long shaft variant (common on 2015-2018 units) before buying.

Key Things to Know

• Quality: Bearings are sealed and pre-lubricated; reviews are limited (2 ratings, 4.0 average) but no widespread failure reports.
• Installation difficulty: Moderate—requires removing the deck, pulling the old spindle, and transferring the pulley and blade. Use a torque wrench on the center bolt.
• Common gotcha: The 3-pack includes spindles for all three blade positions, but some 44-inch decks use a different center spindle (shorter shaft). Measure your center shaft before assuming all three are identical.
• Deck removal: You’ll need to remove the belt and possibly the pulley retaining bolt; a puller may be necessary if the old spindle is seized.

Should You Buy It

If you own a Toro Timecutter with a 44-inch fabricated deck and need to replace all three spindles at once, this 3-pack saves money over buying singles. It’s also a good choice if you’ve already confirmed you have the long shaft variety. For a single bad spindle, buy a standalone replacement to avoid waste.
