Mechanical seed drill M

disccoulter24-row

The M model is a versatile combi seed drill and performs excellently on many different soil types. M model is ideal on cultivated and lightly tilled soils. The robust wedge-shaped coulter penetrates effectively into soft and medium-hard soils. Wide coulter pressure range ensures precise seed placement to desired depth. The wedge-shaped coulter with a carbide tip penetrates the soil effectively and is highly resistant to wear. Optimised sowing depth for all soil types Wedge-shaped design of the coulter helps to control sowing depth precisely. On soft humus soils, coulter maintains the working depth precisely and prevents the coulter from diving too deep into the soil. On hard clay soils, the coulter pressure can be increased hydraulically to ensure that the seed is placed sufficiently deep. The robust coulter of Junkkari’s M model is also suitable for rocky soils. M model adapts to various conditions. By increasing the coulter pressure the M model performs well on disc-tilled fields. Conversely, on plowed fields, a lower coulter pressure is sufficient, with the wedge-shaped disc controlling the working depth. Each coulter operates independently, following the soil surface and measuring the working depth exactly next to the seed to be placed. In the M model, coulter pressure can be adjusted hydraulically within the range of 20-120 kg. Cost-efficiency and reliability Junkkari’s hopper is divided to two parts and it is exceptionally spacious. By adjusting the partition wall, relative volumes of seed and fertilizer hoppers can be changed. Hopper volume is 4200 liters in the 3-meter machine and 5700 liters in the 4-meter machine.
