What It Is

This is a replacement deck long spindle for Husqvarna lawn tractors, designed to drive the mower blade on the outer or middle spindle positions. It’s meant for machines with 48- to 54-inch cutting decks, typically used on residential or light commercial properties.

Fitment & Compatibility

Before buying, verify your mower’s model number and deck size. This spindle fits Husqvarna models including CTH 184T, 494, 224T, 224TFI, 2642, 2642TR, and GT54LS. It replaces OEM part numbers 580856001, 587126105, 587820201, and 580854701. Measure your existing spindle’s shaft length and housing diameter—this unit has a 1-inch shaft diameter and a 3.5-inch bolt pattern. If your mower uses a different spindle length or bearing size, it won’t work. Also confirm your deck has three spindles (left, center, right) and that you’re replacing a “long” spindle, not a short one.

Key Things to Know

• Quality: The 8TEN brand is aftermarket but uses sealed bearings and a hardened steel shaft. Expect similar durability to OEM at a lower price.
• Installation difficulty: Moderate. You’ll need basic tools (wrenches, socket set) and a jack or lift to access the deck. Expect 30–60 minutes per spindle. Watch for the spindle pulley alignment—misalignment can cause belt wear.
• Common gotcha: The included bearing may need greasing before install (check instructions). Also, some users report the bolt holes don’t perfectly align on older decks—use a ratchet strap to flex the deck slightly if needed.
• Noise: A new spindle can be noticeably quieter than a worn one. If you hear grinding after install, check bearing seating.

Should You Buy It

If you own one of the listed Husqvarna models and need a reliable, cost-effective replacement for a worn or noisy deck spindle, this is a solid buy. The 4.9-star rating and near-OEM fit make it a safe choice for DIYers who want to avoid dealer markup. Not for those with oddball deck sizes or who prefer brand-name parts—aftermarket may have slight fit variances.
