The Holaras haulm topper series is available in three models: UM 150, UM 180 and UM 210.
Mechanical removal of haulms saves labour when topping and harvesting onions. Topping and harvesting in one pass has proven to be the most efficient approach. The stable and sturdy model UM 150 is suitable for three-point linkage.
All Holaras onion haulm toppers have two wheels. Ground contacts and sensors ensure automatic (electro-hydraulic) height adjustment, ranging from maximum (coarse) to minimum (fine). The three blade rotor are PTO-driven using a robust gearbox and V-belts.
