John Deere introduces new H423 & H425 harvester heads

John Deere's new H425 harvester head being used on a job site.

John Deere introduces the new, small-size H423 harvester head and the large-size H425 and H425HD. These new attachments replace the previous H413, H415 and H415HD models. Like their predecessors, these heads have 4WD feed.


The H423 harvester head works on the 1070G, 1170G and 1270G base machines and suits thinnings and other fellings where the tree diameter at chest height (BHD) is 150-350 mm.

Furthermore, John Deere claims improvements to hose routing from boom to harvester head and valve block to feed motors. This offers improved durability, easy hose replacement and improved hose protection. It has an operating range of minimum diameter at chest height (BHD) 40 mm to a maximum 500 mm.


The H425 harvester head for the larger size class is available on the 1270G and 1470G base machines.

According to the company, this attachment is ideal for fellings where the tree diameter at chest height (BHD) is 250-500 mm.

Also, John Deere has improved hose routing from loader to harvester head and from valve block to feed motors. The hoses are routed through the frame and well protected within the structures.

Additionally, the H425HD model offers an HD tilt frame, expander pins, feed motor arms and lower delimbing knives.

A wide selection of saw motors and saw bars are also available for the H425 and H425HD harvester heads.

“The new harvesting heads provide excellent performance, durability, measuring accuracy and economy,” said Sakari Suuriniemi, product marketing manager Wheeled Harvesters and Heads at John Deere Forestry. “So far, we’ve received great customer feedback on the latest updates and can’t wait to see the updated harvester heads in action this season.”
