946-04728A Drive Cable Replacement for Troy-Bilt TB200 TB210 TB430 Craftsman M210 MTD SP21HW-H Mower, 78.34 Inch Control Wire Fits 746-04728 Parts, Reinforced Stud

What It Is

This is a 78.34-inch drive control cable replacement for Troy-Bilt TB200, TB210, TB430, Craftsman M210, and MTD SP21HW-H mowers. It connects the control handle to the transmission, enabling self-propel engagement. Reinforced stud design reduces breakage at the attachment point.

Fitment & Compatibility

Before buying, verify:

• Model number – Fits Troy-Bilt TB200, TB210, TB430, Craftsman M210, MTD SP21HW-H. Also works with 746-04728 OEM parts.
• Cable length – Must measure exactly 78.34 inches from end to end. Measure your old cable fully extended (including any plastic sheathing). If yours is longer or shorter, this won’t route correctly.
• Deck size – Typically 21-inch or 22-inch decks; no direct deck size restriction, but cable length must match your mower’s frame.
• Stud type – Reinforced stud (larger diameter than standard). If your mower uses a standard stud, this may not fit the handle bracket.

Quick check: Look for a model tag under the seat or on the frame. Cross-reference with 746-04728. If your original cable has a standard (non-reinforced) stud, this is not a direct swap.

Key Things to Know

• Reinforced stud is tougher – Less likely to snap at the handle end compared to OEM plastic studs. But if your bracket is designed for a smaller stud, you may need to file the hole slightly.
• Installation is moderate – You’ll need to remove the handle, route the cable along the frame, and reattach the spring/lever. Expect 30-60 minutes.
• Measure twice – If your original cable is 78.5 inches or 79 inches, this 78.34-inch cable may be too short. Always measure the full extended length, not just the wire.
• Common gotcha – The cable can bind if routed too tightly near the axle. Leave a slight loop for movement.

Should You Buy It

If you own a Troy-Bilt TB200, TB210, TB430, Craftsman M210, or MTD SP21HW-H with a broken or stretched drive cable, this is a solid, direct-fit replacement at a fair price. The reinforced stud is a genuine upgrade over the OEM plastic version. Just confirm your original cable length and stud type before ordering.
