Belgian potato machinery specialist AVR is upgrading the depth control system on its Puma four-row self-propelled potato harvester to improve accuracy and operator comfort.

The machine’s optional All Conditions Control (ACC) digging unit can set the depth either via diablo rollers or probes that don’t place any pressure on the top of the ridge. 

The latter has been overhauled and is now much more precise, keeping the digging unit – and the whole machine – more stable than before, especially at higher speeds.

Available for new machines in 2023, it will improve operator comfort and ease of use in tough conditions, such as in sprayer tramlines or on slopes, as it requires no manual intervention.

AVR says it should also improve overall harvesting performance, which is determined by accurate depth – too deep and more soil enters the harvester that requires cleaning, and too shallow can lead to increased risk of crop damage.

The 2023 upgrade also allows the operator to reverse the first separating web when blocked in wet conditions.

Ely-based Standen Imports brings AVR harvesters and store equipment to the UK and a standard 4x90cm Puma 4.0 starts at €624,600 (£549,250) retail.

The upgraded ACC system is an additional €28,700 (£25,200).
