Spring-Loaded Belt Tensioner Assembly for John Deere 6100, 6200, 6300 Series with Air Trailer Brakes SKU: QT59166R

A failing belt tensioner causes more than just annoying squealing—it allows belt slip that overheats your engine, undercharges your battery, and leaves you stranded when accessories fail under load. This spring-loaded automatic tensioner keeps steady tension on the drive belt so accessories like the alternator, water pump, and fan run smoothly when your John Deere's reliability matters most.

Why This Assembly Works

• Automatic spring action maintains consistent belt grip to reduce slip and prevent overheating
• Rigid arm and pivot design holds alignment through vibration and dust
• Built specifically for John Deere 6000 series tractors with air trailer brake systems
• Durable construction handles harsh agricultural environments and long service intervals

When your tensioner loses spring force or allows belt wander, this bolt-on replacement restores factory tension specs. S&H Parts has helped farmers keep their equipment running since 1969—call if you need fitment verification for your specific model.
