Adding to its extensive crop care portfolio, Lemken has filled in its biggest gap, launching its Nova 14 self-propelled sprayers at next weeks Agritechnica show.
Available with tank sizes of 4,800 or 7,200 litres and boom widths from 24 to 39 metres the company has now completed its crop care line up with mounted and trailed sprayers as well as fertiliser spreaders under license from Sulky.
It is a well-known fact the manufacturer wanted a self-propelled offering to compete with its rival manufacturers, but the way it bought one to market was unknown until now. Rather than an acquisition the manufacturer has cherry picked its way to market, with various supply agreements in place.
Utilising a chassis made by Brautigam as part of a strategic arrangement stretching back to 2017, it uses wheel motors supplied by Poclain. The engine is a Deutz unit, while the cab frame is from Krone, with Lemken reworking the internals with its own control interface and systems. Liquid management is the manufacturers own design, but the aluminium booms come from manufacture Pommier, which also supplies the booms for the trailed Orion sprayer also to be launched at the show.
The company says being its first SP, attention has been paid to the cab, which is designed for comfort, essential for long working hours. It says sound insulation reduces noise and stress so that operators can focus fully on driving. The sprayer is also available with an optional Category 4 three-stage air filter system, which creates permanent positive pressure in the cab to prevent any fumes from entering. Automatic climate control and a Bluetooth radio also feature.
The application technology is controlled via the manufacturers MegaSpray application on the CCI 800 or CCI 1200 terminal. Functions are said to include width, section and application rate controls, GPS track guidance and job management. The cross-vendor data exchange platform, agrirouter, handles communications with the farm management system back in the office.
Telescopic axles offer track widths from 1,800 to 2,300mm. Hydraulic track width adjustment is available as an option. Tyre widths from 300 to 650mm are available. Ground clearance is 1,200mm An optional hydraulic lift system raises the chassis to a maximum of 1,600mm. Independent, hydropneumatic wheel suspension keeps the ride smooth, while also keeping the boom in balance on uneven terrain.
Adaptive Balancing Control with automatic, proactive guidance keeps the boom in an optimum position and maintains the correct distance to the target surface. Up to five sensors ensure that the individual boom arms adapt to uneven terrain or changes in the crop. A circulation line with individual nozzle control within the boom provides precise application and minimal residue.
The induction hopper has a capacity of 55 litres and provides flow up to the top edge without producing spray mist. The tank is made of polyethylene. It is additionally prepared for a closed transfer system and is height adjustable for improved ergonomics. A colour display above the inductor allows the water hydraulics to be operated easily. The clean water tank holds 660l. An electrically regulated injector agitator with fill level-dependent control maintains a consistently homogeneous mixture inside the tank. Any residue collects in the lowered sump, which can be drained fully.
Availability is mid-2020.
