The new model incorporates the SuperCut 100S saw unit and the new head is available for John Deere 1070G, 1170G and 1270G harvesters.
The H424 is a medium-size harvester head designed for later thinning and final felling where the tree diameter at chest height is 150–430 mm.
The H424 is also well suited for handling crooked wood and working on slopes.
A new PEVO valve improves the harvester head’s performance, adjustability and economy and improved hose routing from loader to harvester head and from valve block to feed motors improves the durability of the hoses.
The new hinged valve block cover makes daily maintenance easy. Grease points and the saw chain oil tank are also easier to access, and the greasing intervals have been extended.
The harvester head’s backwards tilt angle has been increased by 4°, which improves the grip of the stem in the grapple when feeding backwards and makes it easier to work on slopes. The fixed rear knife has been shortened for easier handling of crooked stems and hardwood while the placement of the rear delimbing knives has been changed to improve colour-coding accuracy.
A more robust tilt frame for demanding conditions is available.
The new SuperCut 100S saw unit is for all John Deere harvester heads.
In 2020, all John Deere harvester heads will have the new SuperCut 100S saw unit. The saw unit’s next-generation chain tensioning unit, automatic chain tensioning and mechanical bar locking give it added efficiency and reliability.
The improved chain release makes it easier to replace the saw chain. The new saw unit enable a bigger selection in terms of saw motors and saw bars.
