    摘要： A tracked vehicle (1) comprising: a first and a second track (3, 4); a generator assembly (13) for generating mechanical power; a group of work devices (7) coupled to the generator assembly (13); a first and a second drive wheel (5, 6) coupled to the first and to the second track (3, 4), respectively, and to the generator assembly (13); a user interface (8) for receiving commands (C) from an operator (U); and a control unit (17) connected to the user interface (8) to receive commands from the operator (U); the control unit (17) being configured to: measure an amount of time elapsed between a command (C) sent by the operator and a subsequent command (C) sent by the operator (U); and set the tracked vehicle (1) to a blocked state if the amount of time measured is greater than a first time interval threshold.

    摘要： A snow tooth for a snow tiller for preparing the snowpack of ski slopes; the snow tooth (3) comprising a first projection (6) having a first height (HI; R1) and a second projection (7) having a second height (H2; R2), the first height (HI; R1) and the second height (HI; Rl); the snow tooth being shaped so as to be connected to a rotating shaft and have, in use, a main direction of rotation (F); preferably, the first projection (6) is arranged along the snow tooth so that, in use, it sinks into the snowpack before the second projection (7) in particular when, in use, the snow tooth is attached to a shaft (2) of the snow tiller (1) and said shaft (2) rotates in the main direction of rotation (F).

    摘要： A tracked vehicle (1) for preparing ski slopes has:
    - a chassis (2) extending along a longitudinal axis;
    - a winch mounted on the chassis (2);
    - a boom (16) pivoting about a pivot axis to guide and orientate the cable (13) of the winch (12) between the chassis (2) and the cable anchor point (14);
    - an actuation system for rotating the boom (16) about the pivot axis relative to the chassis in a first and second direction; and
    - a user interface comprising a first and a second switch (37, 38) arranged in front of an operator and to the right and left of each other and configured to rotate said boom (16) so as to steer the tracked vehicle (1) to the right and to the left respectively when the cable (13) is anchored to the cable anchor point (14).
