Oregon 320RNDD009 .050" Gauge 3/8" Pitch 32" Power Match Bar

What It Is

The Oregon 320RNDD009 is a 32-inch Power Match replacement bar designed for EGO battery-powered zero-turn mowers. It uses .050" gauge chain with 3/8" pitch, intended for residential and light commercial mowing where a durable, lightweight bar is needed.

Fitment & Compatibility

This bar fits EGO ZT series mowers with a 32-inch cutting deck, including models like ZT4200, ZT5200, ZT6200, and ZT7000. Before buying, verify your mower’s deck size—this bar is not compatible with 42-inch or larger decks. Measure your current bar’s length (from mounting hole center to tip) to confirm 32 inches. Check that your chain is .050" gauge and 3/8" pitch; if you have a different gauge (e.g., .043" or .063"), you’ll need a matching chain. The Power Match mount is proprietary to Oregon/Ego—do not assume it fits non-EGO mowers without adapter. Always cross-reference your mower’s model number with Oregon’s fitment chart.

Key Things to Know

• Quality: Oregon is a top-tier bar manufacturer. The Power Match design reduces vibration and wear, but it’s not as heavy-duty as a solid steel bar for commercial use.
• Installation: Moderate difficulty. You’ll need to remove the blade and deck shield to access the bar mount. Torque the mounting bolt to 30-35 ft-lbs. Chain tensioning is standard, but the Power Match system requires precise alignment.
• Gotchas: The bar is specific to EGO’s Power Match system—it won’t work on standard chain-drive mowers. If your mower has a different bar mount (e.g., stud-style), this won’t fit. Check that your sprocket has 3/8" pitch teeth; some EGO models use 1/4" pitch.
• Wear: Expect 200-400 hours of life with proper lubrication and chain maintenance. Replace the chain when stretch exceeds 1/8" over 12 links.

Should You Buy It

Buy this if you own an EGO ZT mower with a 32-inch deck and need a direct, high-quality replacement bar. It’s ideal for homeowners who want OEM-level performance without dealer markup. Skip it if your mower uses a different bar mount, chain gauge, or pitch—you’ll need the exact match for your model.
