Low-Cost Fan Drive Solution
![]() |
“I’m a farmer and always looking for a better solution,” says Jon Pigg of AgTronics. “I replaced multiple fan drives over the years. They’re a troublesome component, and I wanted something better.”
The Dura-Cool Fan Drive eliminates common failure points in the Deere Vari-Cool system used on 9-liter engines. Hydraulic pistons, electronic solenoids, and variable-speed components are removed.
“It delivers consistent cooling with no fan speed surging or sudden shutdowns, fault codes or downtime,” says Pigg. “The Deere Vari-Cool was engineered for precision, not for long-term durability in harsh field conditions.”
He has operated his bolt-on mechanical drive system on his own equipment and on neighbors’ equipment for the past two years, and he started selling it this spring.
“It requires virtually no maintenance aside from a belt,” says Pigg. “It’s easy to install for anyone with decent farm mechanic skills. There’s no need to change programming. Just plug in our controller, and it makes the ECM happy.”
AgTronics offers a 9 L drive for $2,100, compared with an OEM drive that costs over $4,000 plus the cost of a technician to install. Pigg plans to introduce a 13.5 L drive soon.
