Faugcol Kevlar Replacement V-Belt for Exmark Radius 48" Deck — 126-6626-SL, Kevlar-Reinforced for Reduced Stretch

Faugcol 126-6626-SL is a Kevlar-reinforced replacement V-belt engineered to restore belt-driven Exmark Radius E, S and X series 48-inch mower decks to reliable power transfer.

If your Exmark mower is slipping, losing deck engagement, or making unusual noises during cutting, the belt is a common wear item to check. The Faugcol 126-6626-SL replaces OEM numbers 126-6626 and 126-6626-SL and is built to match the fit and routing of Exmark and Toro Radius 48-inch deck models. Constructed with a Kevlar core for tensile strength and abrasion resistance, this belt is intended to provide consistent grip on pulleys and longer service life compared with generic belts.

Which Exmark and Toro decks does this belt fit?

This belt is sized and shaped for 48-inch Radius decks used on several Exmark E, S and X series machines. It is compatible with models listed by Exmark and Toro under the OEM numbers 126-6626 and 126-6626-SL. Always verify your deck model and routing before ordering to ensure a correct match.

• Fits Exmark Radius X-Series: RAX651GKA484A3

How does the Kevlar reinforcement help performance?

Kevlar fibers increase tensile strength and reduce stretch compared with standard rubber-only belts, helping maintain proper tension and pulley engagement. That consistent tension reduces slipping under load and keeps blade speed steadier for a more even cut. The reinforcement also improves resistance to heat and abrasion from deck edges and debris.

• Kevlar core limits stretch under load
• Improved abrasion and heat resistance
• Maintains belt profile for better pulley contact
• Designed for heavy-duty mowing conditions

What should I check during installation and maintenance?

Inspect pulleys, idlers and spindle bearings before installing a new belt; worn components shorten belt life. Follow the mower’s belt routing diagram and set correct tension — over-tightening can cause premature wear while under-tightening leads to slippage. Periodic cleaning of the deck and belt path from grass build-up extends service intervals.

• Confirm correct belt routing on your deck model
• Replace damaged pulleys or bearings to avoid rapid belt wear
• Apply manufacturer torque specs and tension checks where specified
• Keep deck and belt path free of debris

How long can I expect this replacement belt to last?

Service life depends on usage patterns, terrain, maintenance and proper installation. Under normal commercial or residential use with good maintenance, a Kevlar-reinforced belt typically outlasts basic belts, but high-impact conditions will still shorten lifespan. Inspect the belt regularly for cracking, glazing, missing ribs, or fraying to determine replacement timing.

• Longevity improved with correct tension and aligned pulleys
• Inspect for visible damage each mowing season
• Replace immediately if slipping or unusual noises occur
• Prolong life by keeping debris cleared from the deck

Who is this for: The Faugcol 126-6626-SL belt is aimed at owners and technicians who service Exmark or Toro Radius 48-inch decks (E, S, X series) and need a direct-fit replacement with enhanced strength. It suits landscapers, property managers and homeowners who want a durable V-belt built to resist stretch and abrasion while matching OEM routing and performance. If you maintain your own equipment or operate multiple machines, choosing a Kevlar-reinforced replacement helps reduce downtime and keeps deck drive systems running smoothly.
