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

Meet the Mitsuboshi Super KB Standard V-Belt 0.63 in. W x 50 in. L — a purpose-built drive belt crafted for riding mowers that demands dependable performance. This belt threads into your mower’s belt path with a precise 50-inch length and 0.63-inch width, using the standard 5LK profile to deliver consistent power transfer under mowing conditions.

Part of the trusted Super KB line, this belt is engineered to keep your mower moving smoothly from season to season. The sleeve packaging protects the belt during shipping and storage, helping it arrive pristine and ready for installation.

Why this belt stands out

  • Exact fit for many riding mowers: Standard 50" length, 0.63" width, and 5LK profile designed to slot into common belt paths without modification.
  • Reliable power transfer: Built to handle typical mowing loads with steady grip and torque transmission.
  • Protective packaging: Sleeve packaging shields the belt from creases and damage before you install it.
  • Trusted brand: Mitsuboshi’s Super KB line emphasizes dependable performance for lawn-care equipment.

Use cases and installation tips

This belt is ideal for replacing worn or stretched belts on riding mowers that call for a 50" long, 0.63" wide, 5LK-type drive belt. Before installation, verify the mower’s belt path matches the 50" length and 0.63" width. Route the belt according to your model’s service manual, then check pulley alignment and belt tension to ensure even wear and smooth operation after you fire up the mower.

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.
