John Deere rotary harrow-hoe John Deere 400 6m. wheels (urchins) new original from the USA, Odesa region.

RotaryJohn Deere harrow 4.6/ 6/ 9/ 12/m.
It is intended for pre-emergence and post-emergence harrowing of field crops (cereal, fallow, technical crops) with the purpose of:
• surface loosening and soil aeration(//tractor-service.com)
• destruction of filamentous weed entrances

The working organs of the hoe create an ideal background for the initial development of the root system of plants, they mulch well the upper layer of the soil, destroying the soil crust, thereby preserving moisture, they destroy the filamentous roots of weeds up to 100% at speeds of up to 20 km/h.
This makes it possible to switch to herbicide-free technology. With the appearance of a monolithic soil crust on the early seedlings of cultivated plants, for example, corn at the stage of 2-3 leaves, when the use of tooth harrows is impossible, the efficiency of using a hoe increases dramatically.
