Boasting an off-line correction of nearly 5 feet, it will deliver the same precision and sub-inch row accuracy results that have become synonymous with the ProTrakker brand. The WS9000T is specific to John Deere 9000T and 9000RT tractor models. These tractors have a wide swing mechanism that customers want to control and now can. "Just like our other hydraulic hitch models, the WS9000T can be controlled in multiple ways for the implement correction farmers are seeking," says company president Cory Miller.
