946-04661A 746-04661A Lawn Mower Throttle Cable for MTD Troy Bilt Craftsman | fits Troy Bilt TB110 TB230 Craftsman MTD Yard Machine 21 Inch Self Propelled Gas Push Lawn Mowers

What It Is

This throttle cable controls engine speed (choke, fast, slow, stop) on many MTD-branded push mowers. It replaces OEM part numbers 946-04661A and 746-04661A for Troy Bilt TB110/TB230, Craftsman, MTD, and Yard Machine 21-inch self-propelled gas mowers.

Fitment & Compatibility

Before buying, check your mower’s model number (not just brand). This cable fits specific MTD platform mowers with 21-inch decks and self-propelled drive. It’s not universal—verify your OEM part number matches 946-04661A or 746-04661A. Measure the cable length (approx. 40 inches overall, 15 inches of exposed wire) and check that your mower uses a metal lever-style throttle connection (not plastic or push-button). Also confirm the engine type (Briggs & Stratton, Kohler, or MTD) since cable routing can vary. If your mower has a different deck size or is a zero-turn, this won’t fit.

Key Things to Know

• Quality: Aftermarket version is comparable to OEM at a lower price. Some users report slightly thinner metal on the lever end, but it works fine for normal use.
• Installation: Moderate difficulty (30-60 minutes). You’ll need basic tools (screwdriver, pliers, possibly a socket). The hardest part is routing the cable under the deck and through the handlebar—take photos before disassembly.
• Common gotcha: The plastic adjuster nut can strip if overtightened. Hand-tighten only, then test throttle movement before finalizing.
• Compatibility trap: Not all Troy Bilt TB110/TB230 models use this cable. Check the engine deck stamp or owner’s manual for the exact part number.

Should You Buy It

If you have a 21-inch MTD, Troy Bilt, Craftsman, or Yard Machine self-propelled mower with a broken or sticky throttle cable, this is a solid, cost-effective replacement. It’s not for other brands or deck sizes, and you should confirm fitment first, but for the price, it’s a reliable fix that restores full speed control.
