Abstract

Improvements in the construction of pruning and cutting tools, characterized in that the tool comprises a cutting head having a cutting blade, an anvil to cooperate with the cutting blade, and slidingly mounted on the head, a slave hydraulic cylinder secured to the cutting head, a slave piston within the hydraulic cylinder, cooperating therewith, and bias means secured to the anvil biased to move the anvil to an initial position away from the cutting blade, a master hydraulic cylinder hydraulically connected to the slave hydraulic cylinder and of smaller area of cross section thereof, a master piston within the master hydraulic cylinder to cooperate therewith and having a volumetric displacement in the master cylinder of the same order as the volumetric displacement of the slave piston within the slave hydraulic cylinder, whereby the hydraulic fluid in the master cylinder is movable by the master piston to ia the slave cylinder to move the slave piston and anvil against the action of the biasing means towards a final cutting position, in which the cutting blade is close to the anvil and in which it performs a cutting action in cooperation with the anvil.
