Junkkari - Model M - Combi Seed Drill Machine
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.
Versatile and efficient basic model
The Core equipment level offers a machine with uncompromised seeding performance, equipped with the versatile G-Wizard controller. The Core level also includes a semi-lift function, hopper guards, spring-mounted tarpaulin, following harrow and a packer with Steady drawbar as towing device.
Electronic features on top of the Core equipment level
The Plus equipment level includes all features of the Core level, but with G-Wizard+ as the controller, allowing the amount of fertiliser to be adjusted electronically using the controller. The package also includes tramline cluches for seed and fertiliser. Tramlines help with spaying the crops and spreading fertilizer but they also lead to significant savings in fertiliser and seed costs during sowing.
Pro equipment level upgrades to ISOBUS
Compared to the PLUS equipment level, the controller is replaced by an AEF-certified ISOBUS controller. In addition to the remote control of the fertiliser, the seed rate is also controlled from the ISOBUS terminal, which itself is not included in the package. The Pro level package is completed by more efficient hopper level control via two additional sensors.
ELITE equipment level with electric motor feeding and coulter pressure automation
Different from other equipment levels, the feeding devices in the ELITE is powered by electric motors in half-machine sections. The coulter pressure automation adjusts pressure automatically to maintain consistent depth in varying conditions. Control is managed with the updated ISOBUS controller, which includes the TC-SC feature.
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.
Mechanical feeding system is simple, precise, and reliable. Junkkari’s feeding mechanism is built on a mechanical drive that adapts to driving speed. Feed works reliably in all situations, even without electricity from the tractor.
Machine is stable and light to pull due to 20-inch wheels. Large wheels save fuel costs and maintain better soil structure due to lower surface pressure. A following harrow is standard on all Junkkari combi seed drills.
