MTD Genuine Part 731-07135 HOUSING-BATTERY ELEC START OEM part for Troy-Bilt Cub-Cadet Craftsman Bolens Remington Ryobi Yardman Yard-Machine White Hu

What It Is

This is the OEM plastic battery housing (MTD part 731-07135) for electric-start lawn tractors. It holds the battery securely in place under the hood or seat, preventing movement and protecting terminals from debris.

Fitment & Compatibility

Before buying, confirm your mower is from the MTD family—Troy-Bilt, Cub Cadet, Craftsman, Bolens, Remington, Ryobi, Yardman, Yard-Machine, or White. Check the model number on your tractor’s data tag (usually under the seat or on the frame). This housing fits specific electric-start models, not all decks or engine sizes. Measure your battery compartment: the housing is designed for a standard group U1 battery (roughly 7.7" L x 5.2" W x 6.2" H). If your battery is larger or smaller, it won’t fit. OEM part means direct replacement for the original—no aftermarket adapters needed.

Key Things to Buy

• Quality: Genuine MTD plastic—durable, UV-resistant, and matches factory fit. Aftermarket housings may crack or warp.
• Installation difficulty: Easy—remove old housing, transfer battery, snap new one in. No special tools required.
• Common gotcha: Verify the mounting bracket slots align with your tractor’s frame holes. Some models use a different bolt pattern.
• Battery not included: This is just the housing tray—you’ll need your own battery and hold-down strap if yours is missing.

Should You Buy It

If your original housing cracked or is missing, this is the exact replacement for most MTD electric-start tractors. It’s a cheap, hassle-free fix—just double-check your model number and battery size first. Avoid if you need a battery or have a non-MTD brand.
