The 800 mm mower head was designed specifically to meet the needs many professionals or hobbyists who have mini excavators. This market is neglected by many manufacturers because it is considered low usage. Metalmeccanica AFB, however, is very careful to try to meet these needs; in fact, it created this accessory, which makes it almost unique in the industry.
The 800 mm mower head can be applied to mini excavators of (1.4 tons/2.5 tons) equipped with auxiliary hydraulics (hammer); this accessory has a useful cutting area of 75 cm and weighs about 90 kg; the feature that makes it almost unique is the application of a triple helical rotor knife for each support (2 J-shaped curve and a straight total of 36 knives).
The helical rotor allows for excellent quality of work, obtaining maximum results with less effort.
In the heart of the machine is positioned the (helical rotor) placed on high-quality bearings and splined and cemented bushing, where the hydraulic gear motor is placed directly on the head flail mower; the bidirectional motor is totally made of cast iron, with internal or external drainage, according to various needs, makes it a much more aggressive machine, the engine oil pressure operates within the oil pressure capacity of the mini- excavator.
Another factor that makes the difference is the two-way hydraulic motor, totally made of cast iron; the performance remains unchanged because the overheating does not create thermal expansion, in contrast with the traditional aluminum motor; therefore, the quality of the cut remains unchanged.
In the metal structure of the head, there is an inner sheet that functions as a firewall, creating robustness and better durability, while in the back there is a support roller, adjustable in 3 height positions, with a scraper that always keeps it clean.
On the outside of the metal are placed various threaded holes that allow the positioning of the standard seat with pins or for the various couplings of the machine driven, according to the different needs and preferences.
With this study for design and assembly of premium components, the head flail mower of 800 mm can cut a maximum diameter of 5 cm.
