HAULM TOPPER™

AVR machinery for defoliation and crop maintenance
There is increased demand from both the government and consumers for alternative means of removing haulm from potato plants. Mechanical haulm toppers respond perfectly to the current trend of limiting the use of chemicals in agricultural applications. With an AVR haulm topper, you can be assured of efficient haulm removal! The most important goal when it comes to topping haulm is the destruction of the haulm by shredding it and subsequently disposing of it.

The AVR Rafale has been developed to achieve this goal with the utmost precision, while simultaneously limiting fuel consumption. The improved design of the topper has increased its suction power which, in turn, improves the machine’s topping capacity significantly.

The AVR Rafale is available in a wide range of operating widths and models. All toppers come with a three-point hitch at the front as well as the rear as a standard, enabling them to be mounted at either the front or rear of your tractor. The T-gearbox, featuring a continuous shaft, guarantees the necessary torque capacity. All machines come with a continuous shaft with a tube that is 10% thicker tube than in the previous model. The 4x90 cm version has a bearing in the middle of the rotor for increased stability. As a result, the topper is significantly more durable. 

The flail shaft has a rotational speed of 1320 RPM for superior suction and tremendous power. As a result, the haulm is fully shredded. Cutter bars are also included as a standard (except for in the SD model). This increases the capacity, especially when topping green haulm, by up to 55% in comparison to models without cutter bars.
