MTD 731-07154A Top Battery Housing for Troy-Bilt Craftsman Yard-Man Sure Precision B2M7 B2J1 B29Q VB2M VB20 731-07154

What It Is

The MTD 731-07154A is a top battery housing (battery cover/retainer) designed to secure the battery in place on select Troy-Bilt, Craftsman, Yard-Man, and Sure Precision riding mowers and lawn tractors. It fits models with a side-discharge or bagging deck, typically in the 42-inch to 54-inch range, and is used for 12V lead-acid batteries.

Fitment & Compatibility

Before buying, verify your mower’s model number (not just brand) against these compatible series: B2M7, B2J1, B29Q, VB2M, VB20. The housing is OEM replacement for part numbers 731-07154 and 731-07154A. Check your current battery housing’s dimensions: this cover measures roughly 10.5 x 7.5 x 3 inches and fits standard group U1 or U1R batteries. It’s not universal—won’t fit zero-turn mowers, older Craftsman LT models without the listed series, or 20+ amp-hour batteries. To confirm, look for a 10-digit model/serial tag under the seat or on the frame, then cross-reference with MTD’s parts lookup (e.g., on PartSelect or MTD’s site). If your mower has a different battery hold-down system (e.g., strap or rod), this won’t work.

Key Things to Know

• Quality: Made of durable ABS plastic, but can crack if over-tightened or exposed to extreme cold. 4.8-star rating suggests good fit and longevity.
• Installation: Easy—snaps or bolts onto the battery tray, secures with two screws (not included). No wiring or tools beyond a screwdriver.
• Gotcha: Some users report needing to drill new holes if the battery tray is slightly misaligned from older models. Also, check if your battery terminals are on the correct side—this cover may not clear tall terminals.
• Compatibility double-check: If your mower has a battery that’s taller than 7 inches, this cover may not fit. Measure your current battery height first.

Should You Buy It

If your mower’s battery cover is cracked, missing, or loose, this is a direct, affordable OEM replacement for the listed series. For $13, it’s a no-brainer fix—just verify your model number and battery dimensions to avoid returns. Skip it if you own a zero-turn, a different MTD series, or need a full battery tray instead.
