Front suspension on tractors is normally associated with high specification models that do haulage work at high speeds.
So it's interesting to see tractor manufacturer SDF launch a new system for the SAME Frutteto range, whose domain is normally vineyards or orchards.
It's not uncommon to find these types of enterprises located in challenging areas, so the addition of an independent front suspension system has the potential to increase stability and more importantly improve driver safety.
ActiveDrive takes technology used in the companies' premium models, with the addition of sophisticated hydraulics and electronics, to high levels of precision in the reaction times and adjustment of the system. The layout comprises a pair of hydraulic cylinders linking the independent front suspension arms to the axle carrier assembly. The mechanical components are monitored by a combination of two speed sensors, two position sensors, a steering angle sensor and three nitrogen accumulators.
In operation the electronic system analyses the motion and speed of the hydraulic cylinders alongside the tractor's speed and steering angle. The information is used to keep the suspension level, irrespective of load on the front axle. This in turn allows the mechanical system to make use of the entire damping travel available and ensure effective anti-roll control.
Braking performance is also improved on slopes in particular with the inclusion of an anti-dive function which stops the front end 'dipping' under braking, and shifting the centre of gravity forwards, which if unchecked transfers load off the rear wheels.
Available for the Frutteto S and V ranges with power from 80-110hp, in either 3- or 4-cylinder configuration, the tractor recently won Best Specialised prize at the recent Tractor of the Year Awards 2016.
