These chain saws and pruners connect to a hydraulic pump and convert fluid pressure into force that they deliver to their blades to cut tree and shrub branches. Their long handle extends to reach high or deep branches. They are commonly used by arborists, professional tree trimmers, and utility crews working on the ground or in aerial baskets.

Chain saw guide bars keep saw chains aligned during cutting to make even cuts. Also called chain saw blades, they replace worn, bent, or chipped bars on specific hydraulic chain saw brands and models.

Chain saw accessories adapt hydraulic chain saws for specific applications or make connections to hydraulic power units. They fit specific hydraulic chain saw brands and models.
