NOVA Grain Harvester: Huge Possibilities for Small Fields
The ripe grain does not care whether it has grown in a spacious or small field – in both cases it leaves the head with equal readiness when harvesting is delayed. Hence, farmers require high-performance grain harvesters. But a small manoeuvrable machine in a uneasy field in many cases manages to do more that flagship models. And what if dime sizes are combined with high performance, fuel efficiency, modern comfort level and moderate price?
We are happy to present a grain harvester, which complies with all aforementioned criteria: NOVA by Rostelmash.
Travel Specifications
NOVA 340/330 combines are equipped with YaMZ 534 (Stage IIIA) or Cummins QSB 4.5 (Stage IV) engines with the capacity of 180/175 HP accordingly. The large fuel tank provides operation without refuelling during the shift and even longer. This is achieved due to the energy efficient engine and the simple single-drum scheme of the combine as well as due to the straw walkers with minimum power consumption. The drive wheels are driven by a hydrostatic 3-speed transmission, which greatly simplifies combine control.
The machine has a high ground clearance of 50 cm, which is convenient when working on a complicated terrain, running in the fields and leaving them. In a basic configuration the drive axle is equipped with 23,1R26 wheels, and the steering axle is equipped with 18,4R24 wheels. For complicated harvesting conditions a four-wheel drive version with 28LR26/18,4R24 wheels is available for order. Combine overall dimensions (L x W x H 7,945 х 3,400 (3,460 -4WD) х 3,963) allow its travelling over public roads with no trouble.
Attaching Implements, Threshing, Cleaning
The NOVA conveyor feeder house is equipped with a spring-loaded GCFS, a stone trap, a reversing function and inspection hatches for easy inspection. A wide range of adapters can be attached to the combine:Power Stream grain headers, 4 to 7 m wide; Float Stream soybean, 5 m wide; Argus 5-row maize header; Falcon 6-row adapter for sunflower harvesting; Swa Pick pickup with the operating width of 3.4 m.
The distinguishing feature of this combine is its proprietary single-drum thresher with a front booster beater. The drum, 1,185 mm long and 600 mm in diameter, is covered by a concave at an angle of 146°. This ensures really huge threshing area for such a tiny machine – 0.93 m2. Drum rotation varies within 510 rpm to 1,150 rpm, a reduction gear for sunflower/maize harvesting (300/400 rpm) can be installed as an option. The threshing clearance is adjusted from the cab (electrical drive). The thresher ensures high performance and gentle grain threshing at the same time.
Residual grain is separated on 4 straw walkers with an area of 4.3 m2. High efficiency is provided both by large area of sieves and by the optimum amplitude of walkers oscillation. The grain heap is fed into a 2-sieve cleaning system with an area of 3.59 m2 with a large difference between the preparation board and the upper sieve. Thanks to the finger rake on the preparation board, the grain is distributed more evenly and is better blown by the air flow. The fan speed can be adjusted from the cab within 350 to 1,200 rpm.
Grain and Straw
The NOVA's grain tank of 4,9 m3 with a sampler and a filling sensor unloads in less than 2 minutes (50 L/s) and the unload speed can be adjusted. The 4.1 m long auger with the unloading height of 4.0 m enables safe and comfortable grain loading into vehicles.
The machine is equipped with a rake and a single-speed SCS (3000 rpm) as standard, a drum speed reduction device to 1,700 rpm is available as an option. A version of the combine with a stacker of 9 m3 can be ordered as well.
Ergonomics and Safety
The NOVA grain harvester is equipped with a Comfort Cab, which is equipped with air conditioning, heater, filtration system and air boost. The operator's work is supported by the Advisor II on-board information system, which monitors cleaning parameters and functioning of the machine units. Operating functions can be controlled with a joystick, from a panel and via a monitor. It also displays current information, which is duplicated by sound signals and voice announcements.
The manufacturer's dealers will readily give you more information on the NOVA machine. You can also request information directly on Rostselmash web-site.
