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

Engineered by Mitsuboshi, the Super KB Standard V-Belt is a purpose-built 4LK profile drive belt designed for riding mowers. With a 0.5 in (12.7 mm) width and a 72 in (182.9 cm) length, this belt slides into the exact belt path used by many commercial and residential riding mowers, delivering reliable power to your mower's drive system and deck engagement.

Key features that matter in daily lawn care:

  • Profile and fit: 4LK cross-section matches common riding mower pulley sets, ensuring proper alignment and tension.
  • Precise dimensions: 0.5 in width and 72 in length for predictable mounting and a snug fit in OEM-style belt paths.
  • Durable construction: Built to resist heat, abrasion, and environmental exposure typical of lawn care work.
  • Protective packaging: Sleeve packaging protects the belt in transit and during storage, preventing moisture and exposure damage.
  • Reliable brand: Mitsuboshi's Super KB line is trusted for consistent performance in demanding mowing conditions.

Who should consider this belt?

  • Homeowners and landscaping pros who service riding mowers that require a 4LK, 0.5" x 72" belt.
  • Anyone replacing a worn or stretched drive belt to restore smooth wheel drive, deck engagement, and even blade speed.
  • Seasonal mower maintenance shoppers seeking a dependable, long-lasting belt that reduces downtime.

Why choose Mitsuboshi Super KB over generic belts?

  • Exact 4LK profile means fewer misalignments and slip, which translates to more consistent drive force and blade RPMs.
  • Quality materials and precise manufacturing yield better resistance to heat and wear during long mowing sessions.
  • Consistent length and width help preserve pulley alignment, preventing premature belt wear and need for adjustments.

Practical tips for installation and care:

  • Before replacement, confirm compatibility by measuring the old belt's length and width and checking the mower's belt path diagram.
  • After installation, re-tension the belt according to your mower’s specifications to avoid overslip or overtensioning.
  • Store belts in their sleeve packaging in a cool, dry place to prevent cracking or deformation.

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.
