Lawn Mower Drive PTO Belt 1/2" X 83.5" for Craftsman AYP Poulan Husqvarna 139573 532139573 141416 158818 532141416 584449201 33156 GT200, GTH200, GTH220 and GTH2250

What It Is

This is a 1/2" x 83.5" drive belt for the PTO (power take-off) system on select Craftsman, AYP, Poulan, and Husqvarna lawn tractors. It engages the mower deck blades when you flip the electric clutch switch.

Fitment & Compatibility

• Measure your old belt – Confirm length is exactly 83.5" and width is 1/2". Even a 1/4" length difference can cause slipping or poor engagement.
• Cross-reference OEM numbers: 139573, 532139573, 141416, 158818, 532141416, 584449201, 33156.
• Fits these models (and many similar): GT200, GTH200, GTH220, GTH2250 – but check your tractor’s model number tag under the seat or on the frame.
• Deck size doesn’t matter for this belt – it’s the PTO drive belt, not the deck belt. Deck belts are separate and sized by deck width.
• Aftermarket replacement – works fine for most, but OEM belts sometimes last longer under heavy use.

Key Things to Know

• Quality: Good value for the price – 4.4 stars from over 4,500 reviews. Expect 2-3 seasons of normal residential use.
• Installation difficulty: Moderate. You’ll need to route around pulleys and may need to release belt tension by removing the clutch or idler pulley. A belt tool helps.
• Common gotcha: Don’t confuse this with the deck drive belt. The PTO belt is shorter and goes from the engine pulley to the electric clutch. The deck belt is longer and wraps around spindle pulleys.
• Check pulleys: If your old belt wore unevenly or shredded, inspect the electric clutch pulley and idler pulley for damage before installing the new one.

Should You Buy It

Yes, if you need a direct replacement for a worn PTO belt on a compatible Craftsman, AYP, Poulan, or Husqvarna tractor. It’s a solid aftermarket option at a fair price with strong user feedback. Skip it if you need a deck belt or your tractor isn’t in the listed model range.
