583857113 Mower Drive Control Cable Compatible with Husgvarna, Craftsman 21" Walk-Behind Self-Propelled Lawn Mower - Replace 581950506, 581950504, 589818808, 501408102, 581950505, 581950501

What It Is

This is a drive control cable that engages and disengages the self-propelled drive system on specific Husqvarna and Craftsman 21-inch walk-behind mowers. It replaces the OEM cable when the original becomes stiff, frayed, or snaps, restoring smooth forward motion control.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: This cable is designed for 21" deck mowers only. It will not fit 20" or 22" models.
• Model numbers: Fits select Husqvarna and Craftsman self-propelled models (e.g., Craftsman 944 series, Husqvarna LC221A, LC221FA). Check your mower’s model number on the deck sticker or under the seat.
• OEM cross-reference: Replaces OEM part numbers 581950506, 581950504, 589818808, 501408102, 581950505, 581950501. If your original cable has one of these numbers stamped on it, this is a direct match.
• Physical check: Measure the cable length (housing to ends) – should be roughly 30–32 inches. Also confirm the end fittings match your mower’s handle and transmission bracket (typically a ball joint on one end, a loop or clevis on the other).

Key Things to Know

• Quality: This is an aftermarket replacement. Some users report the housing is slightly thinner than OEM, which can cause binding if routed tightly. Lubricate the cable with silicone spray before installation.
• Installation difficulty: Moderate. Requires removing the handlebar cover, disconnecting the old cable from the bail lever and transmission arm, then routing the new cable exactly as the old one was. Plan on 20–40 minutes.
• Common gotcha: The cable may be slightly longer or shorter than the original. If it’s too long, the drive won’t disengage fully; if too short, the bail lever may not reach full engagement. Adjust the cable barrel adjuster on the handle to fine-tune tension.
• Fitment variance: Even with matching model numbers, some mowers have minor differences in handle bracket orientation. If the cable end doesn’t seat cleanly, you may need to file the plastic housing slightly.

Should You Buy It

This is a budget-friendly fix if your original cable is worn and you’re comfortable with basic mechanical work. It’s not a perfect OEM replacement—expect to tweak routing and tension—but it will restore drive function. Skip it if you want a drop-in, no-hassle part; go with a genuine Husqvarna/Craftsman cable instead.
