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

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

The Mitsuboshi Super KB Standard V-Belt offers a purpose-built solution for riders who require dependable power delivery from their mower drive system. Designed specifically for riding mowers, this belt combines reliable performance with the exact dimensions needed to keep your machine running smoothly.

  • Type: 4LK standard V-belt
  • Width: 0.5 in
  • Length: 62 in
  • Color: Beige
  • Packaging: Sleeve packaging protects the belt during shipping and storage
  • Brand & Line: Mitsuboshi, Super KB
  • Application: Specifically formulated for riding mowers

Why this belt matters for your riding mower: a properly sized V-belt minimizes slippage, preserves engine RPM consistency, and supports smooth blade and drive system operation. With the 0.5 inch width and 62 inch length, it fits a common range of riding mower configurations that rely on a 4LK belt profile, helping you maintain efficient cutting performance and reliable starts every season.

Ideal use cases include belt replacement on riding mowers experiencing reduced torque, belt cracking, or accelerated wear. It’s well-suited for homeowners who maintain their own equipment and pros who demand a dependable, long-lasting drive belt that resists cracking and elongation when under typical mowing loads.

Practical tips to get the most from your Mitsuboshi Super KB belt:

  • Verify fit by matching the 4LK designation, 0.5 in width, and 62 in length with your mower’s manual or existing belt.
  • Route and tension the belt according to your mower’s specifications to minimize slipping and maximize longevity.
  • Store spares in the original sleeve to protect from dust, moisture, and UV exposure when not in use.
  • Keep the belt away from oil, heat sources, and sharp edges to extend service life.

Choosing Mitsuboshi’s Super KB Standard V-Belt means selecting a trusted belt that prioritizes consistent performance in riding mowers. It’s a precise fit for demanding daytime mowing and longer maintenance intervals, helping you keep lawn tasks moving without unexpected downtime. Add this 62 inch, 0.5 inch wide, 4LK belt to your cart and ensure your riding mower returns to peak efficiency with every blade spin.

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.
