What It Is

This is a replacement speed control cable for MTD and Cub Cadet walk-behind mowers. It connects the control handle to the transmission, letting you adjust ground speed by moving the lever forward or backward.

Fitment & Compatibility

• Brands: MTD, Cub Cadet, and some Craftsman models with compatible transmissions.
• Models: SC 300, SC 500, HW, E, and Z Series walk-behinds. Also fits select Troy-Bilt and Yard Machines units.
• OEM cross-references: Replaces 746-05209A, 746-05209B, 946-05209A, 946-05209, and 746-05209.
• Measure before buying: Cable length is roughly 36 inches overall (housing plus inner wire). Check your old cable’s total length and end fitting style—this one has a barrel end on the control side and a threaded adjuster on the transmission side.
• Deck size not relevant: Fitment depends on the mower model, not cutting width.

Key Things to Know

• Quality: This is an OEM-style replacement, not a generic aftermarket part. Expect proper fit and durable plastic ends.
• Installation difficulty: Moderate. You’ll need to remove the handle panel, disconnect the old cable from the lever and transmission, then route and adjust the new one. A 10mm socket and pliers help.
• Common gotcha: The cable is pre-lubricated, but if it feels stiff, apply a light spray lubricant to the inner wire before installing.
• Adjustment: After installation, set the cable so the transmission shifts smoothly through all speeds without binding at either end.

Should You Buy It

If you have a compatible MTD/Cub Cadet walk-behind and need to restore variable speed control, this cable is a direct, affordable fix. It’s best for DIYers comfortable with basic mower cable replacement. Avoid if your mower uses a different cable length or end fitting type.
