Poulan Pro 20" Replacement Chainsaw Chain — 3/8" Pitch, .050" Gauge, 70 Drive Links, Hard-Chromed Low-Kickback

Replacement Poulan Pro 20" chainsaw chain engineered for 70 drive links, 3/8" pitch, and 0.050" gauge—built for smooth, low-kickback cutting on compatible gas saws.

This 20-inch Poulan Pro replacement chain (model 577180501) is a heat-treated, hard-chromed cutting loop designed to restore performance to compatible Poulan Pro lightweight gas chainsaws. It matches a 3/8" pitch with a .050" gauge and 70 drive links, offering improved durability in wet or dirty conditions while reducing vibration and kickback compared with older, worn chains.

How will this chain affect cutting performance?

Expect consistent, precise cuts thanks to hard-chromed cutters and heat-treated steel that hold sharpness longer. The chain's design focuses on balanced cutting speed and reduced snagging for everyday pruning, limbing, and firewood tasks.

• Hard-chrome finish resists wear and corrosion for longer edge life
• Heat-treated components maintain cutter geometry under load
• Low-vibration profile improves operator control and comfort

Is this chain compatible with my Poulan Pro saw?

This chain fits Poulan Pro 20" guide bars built for a 3/8" pitch and 0.050" gauge with 70 drive links. Verify your saw’s bar length and the required drive link count stamped on the bar or owner's manual before purchasing.

• Spec: 20" length, 3/8" pitch, 0.050" gauge, 70 drive links
• Model reference: Poulan Pro 577180501 replacement chain
• Check bar markings or manual to confirm fitment

How do I install and maintain this Poulan Pro chain?

Installation is standard for side- or top-mounted chainsaws: align the drive links on the guide bar groove, tension the chain per the manufacturer's spec, and lubricate the bar and chain before operation. Routine maintenance keeps cutting smooth and extends chain life.

• Tension the chain so it snaps back into place but still rotates freely
• Use bar oil before each use and top off the oil reservoir regularly
• Sharpen or replace cutters when performance drops or cutters show wear

What safety or performance differences should I expect?

The chain’s low-kickback geometry and reduced vibration characteristics help lower the chance of sudden reactive forces and make handling easier during prolonged jobs. Always follow safe chainsaw practices—PPE, correct stance, and awareness—because no chain eliminates all risk.

• Low-kickback design reduces abrupt reactions on contact with materials
• Lower vibration improves operator endurance and accuracy
• Hard-chromed cutters maintain cut quality in varied conditions

Who is this for: This Poulan Pro 20" replacement chain is aimed at homeowners and property caretakers who use Poulan Pro gas chainsaws for routine trimming, storm cleanup, and firewood cutting. It’s also a practical replacement option for small-scale pros and landscapers who need a reliable, easy-to-maintain chain that matches common 20" Poulan Pro bars and balances cutting speed with durability.
