After its debut at Eima 2024, Fad Assali brought the “Sidra Prima Sliding” suspension into the field to evaluate its real-world performance. The test also provided an opportunity to highlight the advantages of the “Sidra One” hydraulic suspension compared to traditional leaf spring systems. In both cases, the benefits of the innovations developed in Brescia were clearly confirmed
Awarded last year as a technical innovation in the sector, the “Sidra Prima Sliding”—an electronically controlled steering suspension with hydraulically adjustable track width—was recently field-tested to quantify its operational benefits. The test vehicle was a single-axle Valzelli subsoiler, which traveled on the road with the suspension in a closed position and a track width under two meters, remaining within legal transport dimensions despite being equipped with wide tires. Once in the field, the track was extended to its maximum width of 3.15 meters, enhancing operational safety and stability.

This setup allowed for higher working speeds than typically achievable with conventional suspension systems and, more importantly, offered better soil protection by preventing wheels from repeatedly traveling over the same track. The system ultimately delivered clear, measurable advantages, which were echoed in a second test comparing two four-axle Visini dumpers—one equipped with traditional leaf spring suspension and the other with the “Sidra Es2 Plus” hydraulic self-leveling steering suspension.
The test route—repeated several times over a 20-kilometer loop combining public roads, fieldwork, and yard maneuvers—consistently highlighted the superiority of the “Sidra Es2 Plus” over its leaf-spring counterpart. On the road, it provided greater comfort and stability, while in the field, it reduced fuel consumption by about 2.5 liters per hour. The electronic steering system also improved headland turning efficiency, cutting fuel use by an additional 1 liter per hour.
However, the most significant benefit of the “Sidra Es2 Plus” in field conditions was its superior soil protection, thanks to an even and balanced ground pressure distribution. Penetrometer measurements showed soil compaction reductions of 15% to 25% at depths between 10 and 30 centimeters.
This clearly demonstrates that Fad Assali’s innovations are not just technological showcases—they deliver real environmental and productivity benefits, while also qualifying for incentives under the “GSE-Agricoltura 5.0” plan.
