The AVR Puma potato harvester

Efficient And Comfortable Harvesting

Since the 1950s the AVR Company of Belgium has developed harvesting machines for harvesting potatoes.

Before these harvesting machines, a great deal of manual labor was required. Currently, the four-rowed self-propelled Puma 3 harvester from AVR carries out the complete potato harvest with impressive efficiency.

The Puma 3 uses LINAK actuators for many different tasks.

"Electric actuators are becoming ever more important," notes Stefan Top, Managing Director of AVR."They are simple to apply and can be easily integrated."

Top especially values the functional reliability of LINAK actuators."The actuators have become increasingly more robust in recent years, and this is very important to us."

The machinery is becoming larger, more complex and more efficient and the task requirements of the actuators are growing. Electronics and the communication with various Bus systems are playing a progressively more important role.

In 2001, AVR introduced the first potato harvester outfitted with a Canbus system."With the help of numerous technical innovations, such as the introduction of the Canbus system, we have succeeded in optimizing the potato harvest and making it more efficient," says Top.

The integrated electronics and the multiple feedback position options allow simple and inexpensive integration of electric actuators within the machine's Bus systems.

"The components must communicate perfectly with each other," insists Top.

The LINAK LA35 is one model of electric actuator used in AVR's harvesters. Hall sensors in the actuator relay the position of the spindle to the entire system allowing the driver to configure and perfectly position the rollers and cleaning devices of the harvester from the cabin.
This convenience is one of many reasons for using electric adjustment systems.
Farm machinery requires both precise component configuration and improved operating procedures to work more efficiently. LINAK helps achieve both goals: electric actuators are used to deactivate individual rows in a planter or to reposition cleaning rollers in a harvester.

The increasing complexity of modern farm machinery means more parameters taken into account when planting, fertilizing and harvesting.

Electric actuators are used for more and more precise adjustments of individual components.

Stefan Top expects AVR will expand its use of electric actuators in its future products. AVR already employs a large number of LINAK linear actuators including the LA30LA23 and LA12.
