2 PK A20K PIX Belts Made with Kevlar Compatible with Troy Bilt GW-1128, 1710812, 1710957

What It Is

This is a two-pack of A20K PIX belts reinforced with Kevlar, designed for lawn mower deck drive systems. They replace OEM belts on select Troy-Bilt and MTD models, handling the high-torque load from the engine to the cutting blades.

Fitment & Compatibility

Before buying, confirm your mower uses a 20-inch deck and cross-reference the OEM part numbers: 1710812 or 1710957. These belts fit Troy-Bilt models like the GW-1128, as well as other MTD-built units with the same deck and belt routing. Measure your old belt: it should be 20 inches long (outside circumference) and about 1/2 inch wide. Aftermarket replacements are common, but verify your specific model’s belt diagram to ensure the A20K profile matches. If your mower uses a different belt length (e.g., 18 or 22 inches), this pack won’t work.

Key Things to Know

• Quality: Kevlar reinforcement adds durability over standard rubber belts, reducing stretch and breakage under load.
• Installation: Moderate difficulty—requires removing the deck or belt guard. Use a belt tensioner tool if available; overtightening can damage pulleys.
• Common gotcha: These belts are for deck drive only, not the engine drive (crankshaft) belt. Check your manual to avoid mixing them up.
• Pack value: Two belts for $16.79 is cost-effective, but ensure both are needed—storing one is fine for future replacement.

Should You Buy It

If you own a Troy-Bilt GW-1128 or similar 20-inch deck mower needing OEM-compatible belts, this Kevlar-reinforced two-pack is a reliable, budget-friendly choice. It’s ideal for DIYers who want long-lasting performance without paying premium OEM prices. Skip it if your mower uses a different belt length or you need a single belt only.
