Abstract
A hydraulic secateur or pruning shears includes a device for continuously and smoothly controlling the separation of its cutting blades. This avoids the disadvantage inherent in conventional hydraulic-assisted pruning shears, in which the cutting blades must either be open completely or closed completely, resulting in the entanglement of branches and other undesirable objects with the cutting blades. The controlling device includes a trigger, distribution apparatus for pressurized fluid, an inlet for the fluid and an outlet for the fluid. At least one of the blades is pivotable and activated by hydraulic apparatus. The blades can be set and maintained at any position between the two extreme positions.
