What It Is

This drive cable connects the control handle to the transmission on select Husqvarna, Poulan, and Redmax 21-inch walk-behind mowers, engaging the self-propel mechanism when squeezed.

Fitment & Compatibility

• Exact models: Husqvarna LC221A, LC121FH, L421P, LC221AH, LC221FH, LC221FHE, LC221R, LC221RH, LC221A; Poulan P160RWD, PR675AWD; Redmax CWP21. All must be 21-inch deck versions.
• OEM reference: 587421102 is the genuine Husqvarna part. Aftermarket copies exist but often differ in cable length or end-fitting shape. Measure your old cable’s total length (end to end) and check that the barrel and Z-fittings match.
• What to verify: Remove the old cable first. Compare the new cable’s outer housing length (typically ~36–40 inches) and the end fittings (one barrel, one Z-tab). If the replacement cable is even 1/2 inch off, it won’t engage the transmission correctly.

Key Things to Know

• Quality concerns: The 2.3/5 rating reflects frequent reports of the cable being too short or the fittings breaking during installation. Expect to modify or return if it doesn’t match your exact model.
• Installation difficulty: Moderate. You’ll need to remove the handlebar bolts, route the cable through the handle, and reconnect at the transmission lever. A cable slack adjuster is usually present—set it to minimum slack before final tightening.
• Common gotcha: The housing can kink if forced around sharp handle bends. Lubricate the inner wire with light oil before installing to reduce friction.
• No universal fit: Even “compatible” models may have different cable routing (e.g., under-deck vs. handlebar routing). Check your old cable’s path before ordering.

Should You Buy It

Only if you have one of the listed 21-inch Husqvarna/Poulan/Redmax models and confirm the cable length and fittings match your original exactly. Given the poor ratings, consider buying from a dealer who accepts returns, or pay slightly more for a verified OEM part from a local shop. If your cable is frayed but still intact, try adjusting the tension first—it may save you the hassle.
