For faster cutting cycles with new robust frames
The John Deere H752 - with its new robust design, 6 delimbing knives (4 moving, 2 fixed), powerful feed motors and 57cm felling diameter - is ideal for regeneration harvesting.
The H752 is a new generation harvester head featuring the highly efficient Supercut 100 saw unit, accurate 3-colour marking system (as an option) with reduced dye consumption and redesigned delimbing knives. The new shape of the delimbing knives covers a large area of the stem, ensuring excellent delimbing quality.
The H752 also features a new type of radial piston feed roller motors which provide excellent feed force when it's needed most, at the beginning of the feed.
The powerful Supercut 100 saw unit minimizes bucking damage and the integrated automatic chain lubrication and tensioning system improves sawing performance while reducing maintenance time.
