In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

  • Routine replacements where OEM-style fit and known cross-section are priorities

Installation and care tips

  • Verify that the mower requires a 5LK belt with 0.63 in width and 84 in length before installation
  • Inspect pulleys, idlers, and tensioners for wear or damage and replace any compromised components
  • Follow the mower manufacturer’s tension guidelines when installing the new belt to prevent premature wear
  • Store replacement belts in their sleeve in a cool, dry place to preserve belt integrity

Who benefits

Ideal for homeowners and maintenance professionals who want a reliable, OEM-compatible belt that fits a wide range of riding mowers. With the Mitsuboshi name and the Super KB lineage behind it, you get consistent performance you can trust for regular mowing tasks, even during peak season.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
