Reliability and durability

Simple drive gear kinematics, a solid traction wheels axle, a chopping drum open design, the automatic check system of units and process state.
Operation reliability of hydrostatic drive and traction wheels axle have been tested in off-the-road conditions.
Unreliable harvesters cost dear to farms. And not so much because of repair expenses. Frequent breakages lead to the wrecking of the plans of forage harvesting, livestock production losses and the lowering of the farm
cost-effectiveness. With «Don 680» you can be sure in dependable realization of plan tasks.
The necessary reliability and durability of «Don 680» have been reached, first of all thanks to a straight-through arrangement of the crop flow and a simple drive gear kinematics of the harvester. Some tricks have been found for units design, proved their suitability in practice. So, the use of open type chopping drum lowers the action of dynamic forces and provides reliability and durability of the chopper.
High-pressure hoses fabricated by the firm Manuli are traditionally used by the leading world manufacturers of harvesters.
As a rule, the weakest point of powerful forage harvesters is the engine
power-unit and hydraulic system.
The engine of «Don 680», thanks to an integral heat exchanger, a large air intake area and a water-and-oil radiator steadily masters the daily loads of 10-15 hours.
The most important elements of the «Don 680» hydraulic system are produced by the leading manufacturers of hydraulic equipment. To ensure the special reliability, the line connections are assembled with the help of fitted rings, which allows to make mounting — dismounting repeatedly without the loss of tightness.
