946-04661A Control Cable Compatible with Troy Bilt TB110 TB230 MTD Craftsman 21" Self Propelled Gas Push Lawn Mower, 51 inch Throttle Cable 946-04661 746-04661A Lawnmower Replacement Parts

What It Is

This 51-inch throttle control cable replaces OEM part numbers 946-04661, 746-04661A, and 946-04661A, designed for Troy-Bilt TB110, TB230, MTD, and Craftsman 21-inch self-propelled gas push mowers. It controls engine speed (choke/throttle) by connecting the handle control lever to the carburetor.

Fitment & Compatibility

Before buying, confirm your mower has a 21-inch cutting deck and a self-propelled drive system. This cable fits Troy-Bilt TB110, TB230, TB240, TB280, and many Craftsman models (e.g., 917.374520, 917.374630), plus MTD Yard Machines and Bolens. Measure your old cable’s overall length—it must be exactly 51 inches from end to end. Check if your mower uses a single or dual-cable throttle setup; this is for single-cable systems only. Verify the ends match: a barrel end at the handle and a Z-shaped or loop end at the carburetor. OEM replacements are available but cost more; this aftermarket option is a direct fit for the listed models.

Key Things to Know

• Quality: Cable housing is plastic-coated steel; inner wire is zinc-plated. Some users report slightly stiffer action than OEM, but it works reliably once installed.
• Installation Difficulty: Moderate. Requires removing the handlebar cover, disconnecting the old cable from the carburetor linkage, and routing the new cable through the same path. A zip tie or small wrench set helps.
• Common Gotchas: The cable may be slightly longer or shorter than the original by 1/2 inch—adjust the handlebar mounting bracket position to take up slack. Lubricate the cable ends with light oil before installation to prevent binding. Do not overtighten the carburetor clamp screw; it can strip.
• Compatibility Check: If your mower has a Briggs & Stratton or Honda engine, this cable only fits if the carburetor linkage matches the Z-end design. Measure the distance from the handle control to the carburetor for a quick sanity check.

Should You Buy It

Buy this if you need a budget-friendly, direct replacement for a worn or broken throttle cable on listed Troy-Bilt, Craftsman, or MTD 21-inch self-propelled mowers. It’s not ideal for odd-size decks or dual-cable systems, but for standard single-cable setups, it’s a solid value that matches OEM fitment at half the price.
