The rugged H425HD harvester head is built to work on your toughest jobs. A heavy-duty tilt frame, feed motors and guarding provide even more durability. With a powerful control valve and a top saw option, this high-performance head will become your top choice for wheeled carrier applications.
For simplified maintenance, the H425HD features easy filling of saw chain oil. Daily maintenance can be performed without changing the position of the harvester head. The valve block and grease points are also easily accessible.
The H425HD offers optional saw motor sizes, standard (narrow stem) or buttress (wide stem) saw frames for challenging applications, and processing knives for picking stems from the ground or bunch piles.
