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.

Installation and longevity tips

  • Before installation, disconnect the mower’s spark plug or battery to prevent accidental starts.
  • Inspect pulleys for wear or glazing; replace any damaged components to maximize belt life and prevent premature failure.
  • Mark belt routing carefully and ensure the belt sits properly in all pulley grooves to avoid misalignment.
  • After installing, run the mower at low speed to check alignment and tension, then adjust to the manufacturer’s specified tension for the 4LK belt.
  • Regularly inspect the belt and pulleys during routine maintenance, especially after cutting through thick grass or on uneven terrain.

Choose the Mitsuboshi Super KB Standard V-Belt for riding mowers when you need a dependable, correctly sized replacement that aligns with common 4LK specifications. It’s a practical, no-nonsense solution designed to keep your mower performing at its best season after season.
