A simple and reliable engineering design for proven ruggedness and efficiency



Transmission solutions with maximum efficiency


The mower is driven by hydraulic motors in each wheel (Hydro 124D) or by a transaxle and chains (Hydro 100). That choice made by ETESIA avoids the loss of power and reduces stresses due to machine mass.

The electromagnetic clutch with brake on our ride-on models prevents impacts when the blades start and stop.

Blade transmission using a double-sided notched belt (Hydro 100) or a cardan and two angle transmissions (Hydro 124 D) for accurate blade indexing. Transmission using a standard single belt (Bahia) makes maintenance easier.

The transmission is protected by shear bolts on the blades.

Tested and proven strength and quality


From the time that they are designed, all our machines undergo extreme durability and strength tests. A whole series of test benches run on a 24/7 basis and test the main functions of the machine – engines, driving of cutters, hydraulics etc.


Record ease of accessibility of main mechanical components


Easy access to the cutting system, which can be removed in less than 5 min from the Hydro 100 and in a matter of seconds from the Hydro 124 D, so that the blades can be changed or sharpened very easily in the field .
Access to all the functional parts of the machine – engine, cutting deck etc. – in record time and with no tools.

Proven Ruggedness


The cutting deck is a single 1-cm thick aluminium casting (Hydro 100) or a Mastershock deck (Hydro 124 D). The use of this component in the field of mowing is an exclusive feature from ETESIA.

The chassis is made up of a tubular mechanically welded structure that is fully protected from corrosion by cataphoresis to give it unparalleled durability.
