Description
When you’re out running your 6600, 6800, or 6900 hard all day, the last thing you need is a squealing belt or worse—no cooling at all. This 6PK1700 fan belt is built specifically for John Deere tractors with hydraulic tensioning systems that don’t have air conditioning. At 1700mm with 6 ribs, it’s the exact fit your cooling system needs to keep running smooth through those long field days.
What You’re Getting
- Perfect 6PK1700 spec—6 ribs at 1700mm length for precise fit with hydraulic tensioners
- Built tough to handle the constant load changes your hydraulic tensioner puts on it
- Designed specifically for non-AC setups so you get the right tension without guesswork
- Direct replacement that fits exactly like the original—no modifications needed
Built for Hard-Working Tractors
Your 6600, 6800, or 6900 series John Deere isn’t a weekend warrior—it’s a workhorse that pulls tillage equipment, runs hay tools, and hauls grain carts when the weather window is tight. This belt keeps your cooling fan spinning at the right speed to pull air through that radiator when you’re working the engine hard, whether you’re pulling a deep ripper or running a big square baler.
Made to Last
The beauty of hydraulic tensioners is they automatically adjust as belts wear, but that means the belt has to be built right to work with that system. This one uses materials that resist stretching and cracking under the steady pressure, so it maintains proper contact with all the pulleys throughout its service life.
Installation Notes
Hydraulic tensioners make belt changes easier, but you still need to relieve the tension properly before removing the old belt. Take a good look at all your pulleys while you’re in there—rough or worn pulleys will eat up a new belt fast. Route this one exactly like the original came off, and the hydraulic tensioner will automatically set the right tension once you’re done.
