Four-wheel-drive H425 and H425HD

John Deere H425 harvester head

For big trees

The robust H425 and H425HD harvester heads are designed for big trees and require a large base machine. Design priorities were ease of use, durability, performance, economy, precisely routed hoses, and easy access to service points. John Deere harvester heads are equipped with the new SuperCut 100S saw unit, which features reliable chain tensioning, facilitates saw chain replacement, and enables the use of wide-tail saw bars.
