Valtra tractors can now be ordered with control technology for the hydraulic top link. This ensures that a fertilizer spreader remains horizontal regardless of the fill level.

The Finnish tractor manufacturer Valtra observed that a fertilizer spreader is not horizontal most of the time, primarily due to changes in the fill level and the associated weight reduction during spreading. In other words, if you set the spreader horizontally before filling, the angle changes as you load it. Valtra claims that a full or empty spreader can have a difference of 3 degrees, resulting in uneven or excessive fertilization.

Smart Top Link System for new tractors

Valtra has introduced the so-called Smart Top Link system in its product lineup. The concept involves automatically maintaining the horizontal position of the fertilizer spreader using sensors positioned under the spreader. This option is initially available only for new Valtra tractors from the N, T, Q, and S series.

The Smart Top Link can be installed in the Valtra Unlimited Studio for a price of € 5,000. This studio is a section within the factory where such options are integrated. The option will also become available in the aftermarket in 2024.

Two sensors

The package includes control technology, a hydraulic block, two sensors, and the necessary cables. The Smart Top Link system operates via Isobus and retains an Isobus connection. Two height sensors are mounted at the front and rear of the fertilizer spreader, and their measurements are entered once. The system then automatically compares the data from the two sensors and adjusts the top link as needed.

Valtra initially designed the system for use with a fertilizer spreader, but the sensors can also be installed on other implements if desired.
