Straight-through arrangement of the
straight-line crop flow, a chopper with
24 V-blades, a 290 h.p. turbodiesel, the continuous cutting at a high constant frequency — 20 112 cuts per minute, an unloading accelerator device,
high-efficiency adapters, a wide range of harvesting speeds.
«Don-680»fills up a five-ton track by herbage only in three minutes
Timeliness is one of the principal conditions of a qualitative forage conservation. The observance of the terms of hay cutting and the time of filling the silos with forage allows to keep in full all grass nutritive value and to increase the livestock efficiency index more than on 10%. Only
a high-efficiency harvester, such as «Don 680M», can cope with this task.
Thanks to the blades arrangement in V it is possible to use maximally the advantages of the counter oblique cut: to decrease the cut energy consumption more than on 10% and to shift axleloads from bearings
The important component of «Don 680» ‘s high efficiency is a
straight-through arrangement of the
straight-line crop flow, which is notable not only for high capacity, but also for model process reliability.
At the bottom of the pattern there is a highly persistent chopping drum, equipped with 24 blades and a grinding device. The blades arrangement in V centres the green mass flux, provides high capacity, lowers the fuel consumption, increases mechanical life of the drum bearings.
YAMZ-238 -1 turbocharged, 8V, 290 h.p. - the sufficient margin of power for the highest efficiency
The engine
of «Don-680», equipped with the turbocharging and integral heat exchanger, allows to generate the additional power at load buildup. In the most complex situations the cut fixed frequency is maintained — 20 112 cuts per minute.
The optimal adapters working width, a wide range of harvesting speeds and the unloading accelerator device allow to load the harvester efficiently and to maintain high productivity on the fields of various yield.
