946-04728A Drive Cable for Craftsman M210, M220, MTD RM410, Troy-Bilt TB210, TB200 Mower Parts, Replaces 746-04728, 746-04728A, 946-04728, Rotary 15102

What It Is

This is a replacement drive engagement cable that connects the control handle to the transmission on select Craftsman and Troy-Bilt walk-behind mowers. It controls the self-propel function, allowing you to engage or disengage the drive system.

Fitment & Compatibility

• Direct fit for: Craftsman M210, M220; MTD RM410; Troy-Bilt TB210, TB200. Also fits some later TB230 and TB240 models with the same cable routing.
• Replaces OEM part numbers: 746-04728, 746-04728A, 946-04728, and Rotary 15102.
• Check before buying: Measure the overall cable length (housing + inner wire) from end to end. The OEM cable is roughly 38 inches. If your current cable is significantly different, it won’t route properly. Also confirm your mower uses a single-cable drive system (not a dual-cable or belt-driven setup). Look at the cable end fittings—this cable has a barrel-shaped end on one side and a Z-shaped hook on the other. If your old cable has different ends, it won’t connect.
• Deck size: Works on 21-inch and 22-inch decks common on these models, but deck size alone doesn’t guarantee fit—check the cable routing path.

Key Things to Know

• Quality: This is an aftermarket cable from Troy-Bilt’s own parts line. It’s essentially OEM-spec, using the same gauge wire and plastic housing. No noticeable difference from the original.
• Installation difficulty: Moderate. You’ll need to remove the handlebar cover, disconnect the old cable from both the handle lever and the transmission bracket, then route the new cable exactly as the old one was. A small screwdriver and pliers are enough—no special tools.
• Common gotcha: The cable can kink if you bend it too sharply during installation. Route it in a smooth arc, avoiding tight 90-degree turns. Also, the adjustment nut on the transmission end may need tweaking to get the right tension—too loose and the drive won’t engage, too tight and it’ll drag.
• Durability: The plastic housing is UV-resistant but can crack after a few seasons if left in direct sun. Store the mower indoors or cover the handle area.

Should You Buy It

If your Craftsman or Troy-Bilt mower’s self-propel cable is frayed, sticky, or snapped, this is the correct replacement at a fair price. It’s a direct fit for the listed models and installs without modifications. Skip it if your cable length differs significantly or if you need a dual-cable setup—this is single-cable only.
