Two-sided Fruit-Growing Weeder GRUNNER Adler

WEEDER FEATURES

Ecological, mechanical destruction of weeds in orchards and crops where side weeding is required (incl. vineyards, orchards and berry fruit plantations)
It improves fertility, aerates the soil, as well as the availability of water and nutrients for plants
Multitasking Working Unit:
- Cultivator discs (max. 3 pcs. per side) pull up weeds, loosen the soil, and can also throw out weeds "from a row" or "to a row" of trees (depending on the option)
- The weeding star removes weeds (1 pcs. per side)
Wider coverage of the tilled soil thanks to the star diameter of 700 mm
Two types of weeder adjustment:
- hydraulic: working width from 2000 mm to 3000 mm and the gradient of the Working Unit in the range of 40 degrees
- manual horizontal and the angle of inclination of the weeding star

High-quality materials guarantee an extended lifecyce:
- Cultivator discs mounted on individual hubs with covered bearings, made of wear-resistant Swedish HARDOX steel
- Weeding star made of polyurethane mass with high flexibility to protect trees against damage, high resistance to abrasion, UV radiation and acid soil
