Deck Spindle Assembly with 532174375 Pulley Fit for Husqvarna YTH24V48LS YTH24V42 LS GTH24V52 LS GTH26V52 LS YT48XLS GT48 XLS Lawn Mower Replaces 539112170 532112171

What It Is

This deck spindle assembly (with 532174375 pulley) drives the mower blades on Husqvarna YTH and GTH series lawn tractors with 42- to 48-inch decks. It replaces the worn or failed spindle that supports the blade and pulley, restoring cutting performance.

Fitment & Compatibility

Before buying, verify your mower model and deck size: fits Husqvarna YTH24V48LS, YTH24V42 LS, GTH24V52 LS, GTH26V52 LS, YT48XLS, and GT48 XLS (deck size matters—48-inch decks use two spindles, 52-inch use three). Cross‑reference your OEM part number: replaces 539112170 and 532112171. Measure the pulley diameter (3.5 inches) and spindle shaft (0.625 inch hex) to match your deck’s blade mount. This is an aftermarket assembly, not OEM Husqvarna—check that bolt hole spacing (typically 4.25 inches center-to-center) aligns with your deck’s mounting holes.

Key Things to Know

• Build quality: Aftermarket unit with steel housing and sealed bearings—adequate for residential use, but may have slightly shorter lifespan than OEM.
• Installation difficulty: Moderate (1–2 hours). Requires removing the deck, blade, and belt, then unbolting the old spindle. A impact wrench helps with stubborn bolts.
• Common gotcha: The pulley is pre-installed, but the blade adapter may need swapping from your old spindle—ensure the hex shaft matches your blade’s center hole.
• Belt alignment: After installation, check belt tension and pulley alignment to avoid vibration or premature wear.

Should You Buy It

If you have a Husqvarna YTH/GTH series with a 42–48 inch deck and need a budget-friendly replacement for a failed spindle, this assembly is a solid choice for residential mowing. It’s not for commercial use or heavy-duty abuse, but for the price and one review (5.0 stars), it’s a reliable fix for a common failure point.
