Laverda will be on show with the new ML 800 ARS axial combine at Eima International - Bologna, from 12 to 16 November 2008, Hall 16 - Booth A 23.

Breganze, November 2008. Laverda’s new axial combine harvester, ML 800 ARS, is manufactured in the Agco plant of Hesston, Kansas (USA), and is the first product of the joint venture between Laverda and the corporation of Duluth. Distribution will begin in the Italian market.

Two cutter bars are proposed: a Laverda cutting table 7.00 or 7.60 m in width, with hydraulically controlled reel and Schumacher cutting system, or the Power Flow bar, 7.60 or 9.10 m in width and able to evenly distribute the crop before it reaches the final auger. In both cases, the bar is coupled in a centralized electrohydraulic way that speeds up the time it takes to hitch and unhitch.
The feeding channel is 1,420 mm wide and has 3 bars with 4 chains and floating lower roller. After passing through the channel, the crop reaches the feeding roller, which turns in the anti-clockwise direction. This feeds the rotor from below, distributing the crop in a uniform way with less damage to the straw and lower consumption.

The rotor is 800 mm in diameter and 3,560 mm in length. It can operate at three different speed ranges that are independent from the engine rate: high range (from 260 to 1,050 RPM), medium range (from 186 to 740 RPM) and low range (from 100 to 425 RPM). The crop is threshed by 6 double bars, all interchangeable, that function in opposite flow directions. Cylindrical beaters on 3 rows are assembled between the threshing bars so as to improve the grain separating action. Lastly, 3 rows of knives (7 per row) increase the efficiency of the threshing action when the straw is still green. The concave has 9 sections, each of which consists of 3 units amounting to an overall separation area of 1.75 m² and features a 161° winding angle: the concave can be adjusted for either wheat or corn by adding or removing the metal wires of each section. The concave is regulated by the operator seated in the cab, while the adjustments can be made from both sides of the machine. Direct unloading ensures that the straw is treated in a delicate way.

The crop flows from the rotor towards the generously sized preparation pan (1.58 m × 1.80 m) and from thence to another surface that conveys it by gravity to the Max Flow cleaning system. This consists of fully electronic upper sieves and lower sieves amounting to an overall 5.30 m² sieving area. The falling crop is hit by an air current produced by the transversal flow fan which separates the grain from any impurities to the utmost degree.

With a capacity of some 12,500 l, ML 800 ARS has one of the largest grain tanks on the market, a feature that cuts down on idle times and increases the daily productivity. The discharge speed is 160 l/sec and allows ML 800 ARS to completely empty the tank in 77 seconds. A peculiar feature of the discharge system is its single, direct auger.

 

The Comfortech cab, with its 3.44 m3 volume, has a sound-deadening lining, large access door, seat with air suspensions and an automatic air conditioner. As part of the standard equipment, ML 800 ARS is fitted with the 10.5 inch Managing Console GTA monitor featuring touch screen technology. On request, ML 800 ARS can also be fitted with the Auto-Guide system that obtains three different steering modes in a semiautomatic way.
ML 800 ARS sports a Caterpillar C13 engine with 12.5 l swept volume able to provide 460 HP (338 kW) at 1,900 RPM.

 

Salient features of the innovation and advantages for the user:

Designed for large farms and agro-industrial enterprises, some of the strong points of this pioneering combine include: advanced technology, higher productivity, reliability, simple, all-purpose use.
Qualities achieved thanks to truly ‘astounding’ technical specifications:
the largest rotor in the business, featuring an 800 mm diameter and a length of 3,560 mm fed by a 1,420 mm housing with bladed propellers. A constant crop flow towards the rotor ensures high performance and an unprecedented yield.
The fastest discharging capacity on the market with a record-breaking 160 liters per second. This speeds up the time it takes to discharge the crop, time which can then be dedicated to threshing, thus increasing the productivity of the machine.
A 12,500 liter capacity grain tank, one of the largest on the market: it is so capacicious that the combine can continue to work for much longer periods before needing to be discharged.
The most generously sized cab on the market: because productivity is also improved by providing the best work conditions.
