747-06239B Belt Keeper Rod Compatible with MTD Troy Bilt Cub Cadet Troy-Bilt Craftsman Lawn Mowe XT1 XT2 LX46 LX42 LT46 LT42 Lawn Mower, Replaces 747-06239A 747-06239

What It Is

This is a metal belt keeper rod that holds the drive belt in place on the mower deck, preventing it from slipping off or flopping during operation. It’s designed for MTD-built lawn tractors like Troy-Bilt, Cub Cadet, Craftsman, and others with 42- or 46-inch decks.

Fitment & Compatibility

• Check your deck size: This rod fits 42-inch (LX42, LT42) and 46-inch (LX46, LT46) decks on XT1 and XT2 series mowers. Measure your deck width to confirm.
• Model series: Works with Cub Cadet XT1, XT2, LX, and LT series; Troy-Bilt Pony, Bronco; Craftsman LT1000; and similar MTD platforms. Not for zero-turn or walk-behind mowers.
• OEM vs aftermarket: Replaces OEM part numbers 747-06239A and 747-06239. Aftermarket version should match dimensions (approx. 8.5 inches long, 0.25-inch diameter rod) – measure your old rod to be sure.
• Belt routing: This rod mounts near the mandrel or idler pulley. Verify your deck has the same mounting hole pattern – a single bolt or clip secures it.

Key Things to Know

• Installation is easy: Usually a 15-minute job with basic hand tools (socket or wrench). No special skills needed.
• Common gotcha: The rod can bend if the belt is too tight or if debris jams the pulley. Inspect the belt and pulleys for wear before replacing the rod.
• Quality note: Aftermarket versions are typically steel with a black finish – check for rust resistance. The OEM part is slightly thicker in some batches; compare thickness to your old one.
• Don’t skip the belt: If the rod broke, the belt likely took damage too. Replace the belt at the same time to avoid repeat failure.

Should You Buy It

If your mower deck belt keeps jumping off or you see a bent or broken rod, this is a cheap, direct fix. It’s ideal for DIY owners of MTD-based tractors with 42–46-inch decks who want a quick, reliable replacement without dealer markup. Skip it if your deck size or model is different – measure first.
