Specifications: The 310 & 350 plows have the new Magnum hubs and spindles, which are massively stronger than previously. Bodies have been completely redesigned to allow 34" high-lift jump height. It is now very unlikely that a jump-arm would ever 'top-out' against the mechanical stop and it will be rare for the weight of the plow to be placed on the disk spindles, even in extremely high stump conditions. The unique action of the Savannah jump arm means that the higher the disk is raised, the less is the angle of cut and the greater the rolling effect over a stump, so stresses on the disk and spindle in straight line plowing will be largely eliminated.
