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.

About Product Overview

Mitsuboshi Super KB Standard V-Belt — a purpose-built drive belt for riding mowers that depend on steady, reliable power delivery.

As part of the Super KB family, this belt is formatted as a standard 5LK cross-section, measuring 0.63 inches in width and 87 inches in length. It’s designed to fit compatible riding mower pulley systems with precision. The belt ships in a sleeve to protect it from dust and handling, and its gray color helps with quick identification among your mower components.

Key benefits and compatibility

  • Precise fit for riding mowers that specify a 5LK, 0.63" × 87" drive belt in the Mitsuboshi Super KB lineup.
  • Supports consistent power transfer to the mower’s drive and cutting deck, helping maintain mowing performance over time.
  • Gray belt color and sleeve packaging streamline storage and inventory management on long-term projects or seasonal maintenance.
  • Durable cross-section designed for standard riding mower duty, reducing the risk of misalignment when installed correctly.

Who this is for

  • Homeowners and lawn-care professionals with riding mowers that require a 5LK belt in 0.63" width and 87" length.
  • Anyone replacing a worn, cracked, stretched, or glazed belt to restore efficient mowing performance.

Installation and care tips

  • Verify compatibility by checking your mower’s belt routing diagram and manual for the exact 5LK, 0.63" × 87" specification.
  • Before installation, inspect pulleys and the tensioner for wear or damage to prevent premature belt failure.
  • Install the belt with the correct routing and ensure proper tension to maximize belt life and performance.

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.
