2024 Maschio Gaspardo Katia 550

KATIA is a forward reach professional hedge cutter with compass arm for grass, shrubs and bushes for road maintenance. It can be coupled with tractors with a power between 80 and 100 HP with minimum wheel track of 7.2 ft and a weight of at least 7,716 lbs, allowing an extension of up to 21.3 ft.

The peculiarity of the model KATIA lies in the compass arm system which, allowing the hydraulic forward movement of the head, ensures the operator with greater control, as required for road maintenance. The safety systems include OVER CENTER on the first arm which prevents it from suddenly lowering to the hydraulic safety system with adjustable hydropneumatic shock-absorber, up to the mechanical shockproof safety system which discharges the hydraulic pressure of the rotor in case it blocks.

The CFS (Contour Following System) is available on request, which allows the floating of the arm by means of a potentiometer that makes it possible to follow the profile of the ground without having to intervene on the controls, protecting the arm and the hydraulic motor from damage.

KATIA can be coupled with different types of 4.1 ft wide heads with belt or direct drive. KATIA offers different combinations for the cutting parts, blades and hammers. The spiral type rotor allows the double rotation direction and the floating function up to 246° of rotation, ensuring maximum performance.

In addition to the classic heads for twigs, hedge bars for cutting shrubs up to 0.6 in and the attachment for cutting branches up to 3.9 in are also available. MARGHERITA also allows cleaning road side ditches and channels thanks to the ditch cutter. The high efficiency of this equipment comes from the use of a hydraulic motor, an ideal solution for the drive of particular accessories that work with high extensions.

Features may include:

The spiral position of the tools ensures lower power absorption. Reversal of rotation is timed, reducing the risks of accidental breakage.

Hydraulic circuit can be blocked by shut-off valves, this allows the user to safely perform maintenance operations.

The gear pump is compact and protected so as not to interfere with work and uses a safety valve which intervenes for discharging if the rotor is blocked. It can be of two types:

• Direct drive;

• With belt drive.

A double safety device is triggered when the arm meets an obstacle: the first protection consists of a nitrogen accumulator shock absorber. If this is not sufficient, a relief valve allows to rotate the arm backwards by 90°.

A valve placed on the cylinder of the first arm makes it possible to keep exactly in the set position, ensuring precision cuts even for extended periods, such as when cutting hedges. In the event of failures, the valve also acts as a safety system, keeping the arm in position and avoiding sudden failures.

This system allows the “floating” of the arm, following the profile of the ground, without intervening on the controls. After having memorised a position of the arm, the machine automatically adapts to the ground profile, following its unevenness. By means of a pressurised nitrogen accumulator, the thrust of the arm on the hydraulic system is counterbalanced and, the further away the arm works, the more backpressure is needed by the system.

Hardened steel ground plugs and bushings for greater wear resistance.
