Forage harvester DON 680M
GENERAL DESCRIPTIONThe harvester is intended for average and small stockbreeding farm with pack up to 500 heads or large stockbreeding farm, which use such class machines for daily feeding.
-
Technological tract
The technological tract components shape on Don-680M harvester allows the shredded product to move with minimally changed movement direction, what reduces energy costs for the product transportation.
Final-shredding device of rotor type included into standard set is envisaged for installation into transporting channel.
For the purpose of providing the stable technological process and, as the result, getting of excellent forage, each further operation in the forage harvester should run with higher line speed, than the previous one.

Shredding drum
The shredding drum of Don-680M forage harvester has V-installed knives providing continuous cut of forage mass, because of the one of such knives is always in gearing with counter-cutting plate.
Unloading accelerator
Application of the accelerator in the harvester unloading device provides unloading of shredded mass at a high speed, what allows compacting the silage mass when loading a vehicle. Therefore, the large loading of vehicles in tonnage is achieved.
Final shredder
DON 680M basic set includes the final shredder of corn seeds – necessary condition for high-quality corn silage. Its purpose is to shred the corn seed shell. Such forage contains more nutrients and higher in respect of energy value.
Silage line visor extension
The extension of silage line visor included into Don-680M standard set gives a possibility of unloading into a vehicle deck with low sides in windy weather without losses of forage mass.

CABIN
DON 680М is equipped with Comfort Cab which completely meets modern ergonomics requirements. The standard cabin set incorporates air-conditioner, heater, cooler and audio-preparation. The harvester main controls are arranged on the operator’s RH control panel. Excellent round view is provided from the operator’s station. Steering column and driver’s seat are adjusted for the operator’s anatomical characteristics. Anatomically calibrated control joystick with control buttons. Informational panel with control system. In one word, the conditions for continuous and efficient operation are made.

POWER PLANT
DON 680М harvester is equipped with 8-cylinder turbocharged engine with integrated heat exchanger. Compact V-type engine cylinders position allowed to arrange it laterally.
This and optimal scheme from the point of view of energy transfer to the harvester working components. Power in outputted directly from the engine “tip”, what much simplifies the power plant design.
All these aspects allowed achieving low fuel consumption, i.e. 430g per a ton of silage. The fuel tank capacity is enough for 11 hours of operation, what is rather enough.
