Innovative technologies in Ferri's new hybrid brush cutter
Last November, at EIMA 2024, Ferri introduced a new hybrid hydraulic brush cutter, which integrates the hydraulic energy supplied by the tractor for the movement of the arms and the electrical energy - approximately 700 Volts - for the cutting head. The TSP Hybrid model is the result of a collaborative effort by Ferri and 4E-Consulting, a Ferrara-based company belonging to the ZAPI Group, and marks an important step forward in terms of efficiency and performance.
System integration work was focused on a careful sizing of the key components of the vehicle, such as the inverter and the ZAPI Group motor, with the aim of achieving performance comparable to that of traditional models. One of the most significant aspects of this transformation was the creation of the Power Distribution Unit, which includes a HVIL (High Voltage Interlook Loop) generator, fuses and space to house a DC/DC (voltage converter).
The development of the Power Distribution Unit required an in-depth study of the cooling circuit and the electrical power and signal circuit, which run for over 10 meters along the brush cutter arm. Another strong point of the equipment is the programming of an advanced control software, which will allow for future updating to support ISOBUS standards, and which permits automatic control of the working speed, thanks to the integration between tractor and equipment. Other advantages of the TSP Hybrid model worth mentioning include its high operational efficiency which – claims the Romagna-based company – increases energy efficiency by 40% compared to traditional brush cutters, while improving profitability and precision of the head.
On the safety front, the absence of a PTO shaft significantly reduces the risk of injury as it eliminates the risk of the user getting entangled when setting up the tool. Ferri's new brush cutter also stands out for its telescopic terminal with adjustable anti-wear pads, which can reach 6.2 meters, and for the Reverse Safety device which protects the machinery in the event of impacts when the tractor is working in reverse.
