Mobile hedge trimmer apparatus comprising:

a first portion, said first portion acting as a mobile base adapted to rest on a ground and advance along a path and comprising a plate and at least two wheels, preferably two pairs of wheels,
a second portion, said second portion comprising a pillar adapted to tilt on two axes perpendicular to each other, said pillar comprising a first cutting blade and a second cutting blade, said first cutting blade being adapted to slide along said pillar and said second cutting blade being integral with said pillar,
a control unit, and
sensors connected to said control unit;
wherein a control unit is adapted to adjust the inclination of said pillar on said axes and/or the position of said first cutting blade along said pillar, receiving information from said sensors,
wherein said sensors comprise at least one tool for measuring an inclination of the ground and/or of said pillar and at least one movement sensor or advancement detector,
wherein said control unit is adapted to receive information from said sensors repeatedly, in particular periodically, and to consequently adjust the inclination of said pillar and/or the position of said first cutting blade along said pillar.

Method for adjusting the height of a cutting blade connected to a hedge trimmer apparatus resting on a ground on which the hedge to be cut is arranged and moving along a path on the ground, wherein said cutting blade can be moved in height relative to the ground, the method comprising the steps of:

A) receiving information about an advancement range of the apparatus from a tool for detecting an advancement placed on board said hedge trimmer apparatus;
B) receiving information about the inclination of the ground from a tool for detecting an inclination placed on board said hedge trimmer apparatus;
C) processing information received by a control unit using a trigonometric law and calculating a height variation of the ground;
D) sending a command signal to a motor moving the cutting blade according to the height calculated at step C;
E) repeating steps A to D for each advancement range along said path on the ground.
