NEW 42" POULAN PRO MANDREL 130794 128774 137646 137645, New,

What It Is

This is a replacement mandrel (spindle assembly) for the cutting deck of select Poulan Pro, Husqvarna, and Craftsman lawn tractors. It houses the blade and bearing, transferring power from the belt to spin the blade for cutting grass.

Fitment & Compatibility

• Deck size: Fits 42-inch cutting decks (verify your deck is exactly 42").
• Models: Direct replacement for OEM part numbers 130794, 128774, 137646, and 137645. Commonly used on Poulan Pro, Husqvarna, and Craftsman models with 42" decks from the early 2000s to present.
• Check before buying: Measure the distance between mounting bolt holes (typically 4.0" center-to-center) and the pulley diameter (usually 3.0" or 3.5"). Confirm your existing pulley is removable/reusable — this mandrel comes without a pulley.
• OEM vs aftermarket: This is an OEM Poulan part, not a generic aftermarket, so fitment and bearing quality are consistent with factory specs.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket set, jack/stands to lift the mower, and a puller to remove the old mandrel if it’s seized. Expect 30-60 minutes per mandrel.
• Common gotcha: The mandrel does not include the pulley, blade, or hardware. Reuse your existing pulley and blade bolts — replace if worn.
• Durability: OEM bearings are sealed and greased; they typically last 2-3 seasons under normal residential use. If you mow heavy or wet grass, inspect annually.
• Wobble check: After installation, spin the blade by hand. Any wobble means the shaft is bent or the bearing is seated wrong — do not run the mower.

Should You Buy It

If you have a Poulan Pro, Husqvarna, or Craftsman with a 42" deck and need a direct, reliable OEM replacement for a worn or noisy mandrel, this is a solid buy. It’s priced competitively with aftermarket options but offers better fit confidence. Best for DIY homeowners who can handle basic deck removal and spindle swap.
