587421102 Drive Cable for Husqvarna LC221A LC221FH LC121FH LC221R Poulan PR675AWD Redmax CWP21 21-Inch Walk-Behind Lawn Mower – Clutch Drive Control Traction Cable Replacement

What It Is

This is a drive control cable that engages the self-propel (traction) system on specific 21-inch walk-behind mowers from Husqvarna, Poulan, and Redmax. It connects the handlebar lever to the transmission, letting you move forward without pushing.

Fitment & Compatibility

• Exact models: Husqvarna LC221A, LC221FH, LC121FH, LC221R; Poulan PR675AWD; Redmax CWP21. All are 21-inch deck, self-propelled mowers.
• OEM vs aftermarket: This is a Husqvarna-branded replacement (part 587421102). Check your mower’s manual or current cable for the same part number stamped on it.
• Measurements: Cable length is roughly 40 inches overall, with a 4-inch sheath and specific end fittings (a barrel at the lever end and a loop at the transmission end). Compare to your old cable before buying.
• What to verify: Ensure your mower uses a single cable for drive engagement (some models have separate speed-control cables). Also confirm the handlebar lever type—this cable fits standard squeeze-lever designs, not thumb-lever or electric-start variants.

Key Things to Know

• Low rating warning: 2.0 stars from only 2 reviews suggests quality control issues or poor fit on certain batches. Carefully inspect the cable ends and sheath length against your original before installing.
• Installation difficulty: Moderate. You’ll need to remove the handlebar cover, disconnect the old cable at both ends, and route the new one through the same path. A cable tie or zip-tie may be needed to secure it.
• Common gotcha: The cable can be too tight or too loose if the transmission lever is worn or misaligned. Adjust the cable barrel nut or check for debris in the drive pulley before final tightening.
• Lubrication: Apply light oil to the cable ends and pivot points after installation to prevent binding and extend life.

Should You Buy It

Only if you have one of the listed models and can confirm the cable matches your original’s measurements and end fittings. Given the low rating, consider cross-referencing an OEM Husqvarna 587421102 from a dealer or checking for a higher-rated aftermarket alternative (like Oregon or Stens) if available. This is a budget stop-gap, not a long-term fix for heavy use.
