946-04661A Control Cable Compatible with Troy Bilt TB110 TB230 Craftsman MTD Yard Machine 21 Inch Self Propelled Gas Push Lawn Mower, 746-04661A Throttle Cable Lawnmower Replacement Parts

What It Is

This is a replacement control cable (throttle/governor cable) for select Troy-Bilt, Craftsman, MTD, and Yard Machines self-propelled gas push mowers with 21-inch decks. It connects the throttle control lever to the engine carburetor, letting you adjust engine speed and engage the blade brake.

Fitment & Compatibility

• Exact fit for models: Troy-Bilt TB110, TB230; Craftsman models with 21-inch steel decks; MTD and Yard Machines with similar frame.
• OEM cross-reference: Replaces 946-04661A, 746-04661A, and 946-04661 (aftermarket, not OEM).
• Check before buying: Measure your old cable length (approx. 40-45 inches overall). Verify your mower uses a standard throttle lever (not a variable-speed or dual-cable setup). Confirm your engine brand (Briggs & Stratton, Kohler, or MTD) — this cable fits most common carburetors on these models.
• Common gotcha: Does not fit walk-behind mowers with side-discharge only or electric start models unless listed.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to remove the handlebar cover, disconnect the old cable from the carburetor lever and throttle bracket, then route the new one. Basic hand tools (screwdriver, pliers) required.
• Quality: Aftermarket, not OEM. Most users report it’s sturdy and matches OEM specs, but a few note the plastic end fittings can be slightly looser than original. Lubricate the cable before installation to improve longevity.
• Common gotcha: The cable may need slight adjustment after install—use the barrel adjuster at the handle to fine-tune throttle response. If your mower has a blade brake cable (separate from throttle), this part won’t replace that.
• Durability: Good for the price; expect 1-2 seasons of normal use. If you mow heavy or damp grass, check for fraying at the carburetor end annually.

Should You Buy It

If you have a compatible Troy-Bilt, Craftsman, MTD, or Yard Machines 21-inch self-propelled mower with a broken or stiff throttle cable, this is a reliable, low-cost fix. It’s a solid aftermarket alternative to OEM (which costs 2-3x more) and works well for DIY repairs. Skip it if you need an exact OEM fit for a less common model or if your cable routing is unique (e.g., zero-turn mowers).
