NEW: W1 and W1 Plus weighing system

The new W1 and W1 Plus weighing systems, exclusively developed for WINTERSTEIGER by Harvestmaster, combine unrivaled precision and speed in weight and moisture measurement. The weighing system is based on unique measurement and grain handling technology. The compact and cost-effective system is designed to mount on the Classic Plus and Quantum plot combines.


The system is capable of processing all common field crops. The W1 weighing system measures the weight only and the W1 Plus weighing system also determines the moisture content of your harvested material.
