The light-weight compact head for thinning and regeneration timber
The John Deere H754, a light-weight harvester head, is designed for thinning and regeneration harvesting. It is well suited to delimbing difficult stems, thanks to a short frame and optimal placement of the delimbers. The four-wheel drive of the H754 permits installation of optimal multi-tree handling equipment.
