Set of 6 Troy-Bilt TB 2350 Super Bronco 50 Mustang XP 50 FAB Mustang XP 50 Mustang Fit 34 Lawn Mower Blades Fits Models 13AAA1KQ066 13AQA2KQ011 13WQA2KQ011 17ANCACZ066 17AQNAMU066 17ARCACQ011

What It Is

This is a set of six replacement blades for Troy-Bilt Bronco and Mustang series riding mowers with 50-inch fabricated (FAB) decks. Designed for medium to large lawns, these blades provide a clean, even cut and replace worn or damaged OEM blades.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch fabricated deck (not stamped steel). These blades fit models: 13AAA1KQ066, 13AQA2KQ011, 13WQA2KQ011, 17ANCACZ066, 17AQNAMU066, and 17ARCACQ011. Compatible with Troy-Bilt TB 2350, Super Bronco 50, Mustang XP 50, and Mustang Fit 34. Measure your existing blades: length should be ~20.5 inches, center hole ~0.625 inches (5/8”), and sail height ~2.75 inches. These are OEM-grade replacements, not universal—do not use on 42-inch or 46-inch decks.

Key Things to Know

• Quality: Heat-treated steel with a durable coating resists rust and stays sharp longer than budget blades. Edge retention is good for standard grass, but heavy mulching may dull them faster.
• Installation: Moderate difficulty. You’ll need a socket wrench and torque wrench (recommended torque: 70–90 ft-lbs). Jack up the mower safely and block the deck. Never sharpen these—replace when nicked or bent.
• Common gotcha: The set includes six blades, but some 50-inch decks use only three (two per spindle). Verify your spindle count—most 50-inch FAB decks are three-spindle, requiring six blades.
• Balance: Each blade is balanced from the factory. Still, check for warping before install—bent blades cause vibration and uneven cut.

Should You Buy It

Buy this set if you own a Troy-Bilt 50-inch FAB deck mower and want a reliable, direct-fit replacement that matches OEM specs without paying dealer markup. It’s ideal for homeowners who maintain their own equipment and cut 1–2 acres weekly. Skip it if you have a stamped deck or need mulching-only blades—these are standard lift blades.
