532125907 125907X Lawn Mower Drive Belt for Husqvarna/Craftsman/Poulan YTH20K46 GTH52XLS GTH26V54 GTH264T LT2213A CTH126, for AYP 125907 592855301 105732X 120302X / Aramid Cord 1/2 x 90 Inch

What It Is

This is a 1/2-inch wide by 90-inch long Aramid cord drive belt (OEM part #532125907 / 125907X) that transfers power from the engine pulley to the mower deck spindles on select Husqvarna, Craftsman, and Poulan lawn tractors with 46-inch or 54-inch cutting decks.

Fitment & Compatibility

Before buying, verify:

• Deck size: Fits 46-inch (YTH20K46, LT2213A, CTH126) and 54-inch decks (GTH52XLS, GTH26V54, GTH264T). Not for 42-inch or 48-inch decks.
• Model check: Confirmed for Husqvarna YTH20K46, Craftsman LT2213A, Poulan CTH126, and AYP-built GTH models. Cross-references to OEM #592855301, 105732X, 120302X.
• Measurements: Belt is 1/2" wide x 90" outside length. Measure your old belt end-to-end (not compressed) to confirm.
• Aftermarket note: This is an aftermarket replacement using Aramid cord (stronger than standard rubber). Works fine for most residential use, but OEM Husqvarna/Craftsman belts have different part numbers.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to remove the mower deck, release the belt tension idler pulley, and route the belt around all three spindle pulleys and the engine pulley. Allow 30–60 minutes.
• Aramid cord vs. Kevlar: Aramid is nearly as strong as Kevlar and resists stretching better than standard rubber belts. Good for heavy grass or occasional rough terrain.
• Common gotcha: The belt must be routed exactly as shown in your deck diagram—wrong routing causes slipping, noise, or belt flip. Take a photo before removing the old belt.
• Wear check: Inspect spindle pulleys for rust, wobble, or worn grooves before installing—bad pulleys will shred a new belt quickly.

Should You Buy It

Yes, if you need a reliable, affordable replacement for a 46" or 54" Husqvarna/Craftsman/Poulan tractor and don’t mind a 30-minute install. Skip it if you want an OEM-branded belt (pay more) or if your deck is a different size.
