Four blades and dual hinged outer frame arms immediately make the Nomad ST440 tree spade stand out. Blade position gives the operator a comfortable and clear view of the spading action. Incredibly important when transplanting evergreen trees is taking care not to damage the wide lower branches. The Dual Tree Hugger hinged frame arms allow the operator to take extra care while positioning the tree spade to avoid any unnecessary damaging trauma to the tree. The ST440’s spades are made of 1/4” high alloy steel that hardens with usage, for reliable digging and compacting performance.
