Grain harvester ACROS 550 - 585 

Beater-normalizer with combs and retractable pins arranged at the input of inclined chamber and actively levels the reaped crop mass. Together with floating transporter shaft, it promotes its rapid and uniform feeding in conditions of strong graining.

Traditional threshing system used in the harvester is reasonably considered as a strong ACROS feature. Classical single-drum thresher represents objectively the best combination of high capacity and low energy expenses. Besides, it differs by minimum risks of grain damage and care of straw.

Ears remained after threshing process are transferred to autonomous final grinding device. Then, the separated grain is distributed along the whole width of shuttle board. By means of this operation, the complete cleaning cycle is achieved without a risk to overload the sieves. The device is equipped with 3-blade rotor, which, in comparison with final-threshers of drum type, threshes more smoothly and reduces the grinding of grain.

Practice has shown that the grain unloading takes not less than 5% of working shift. In order to reduce this time, ACROS harvester is equipped with highly productive unloading device (unloading speed is up to 90 L/sec.) and large-volume grain tank (9000 L). The complete grain tank unloading takes less than two minutes.

Smart Launch

Smart Launch comprises a patented device of separated consequent activation of unloading and horizontal worms. Such device provides high-speed unloading with minimum risk of clogging. Also, the cycling unloading is possible due to Smart Launch used in the harvester. One more advantage consists of that the unloading worm at its deactivation always frees from grain remainders not allowing its losses at folding the worm – the situation which always occurs in many other harvesters.

ACROS classical threshing and separation system practically does not damage the straw. Depending on the supposed use, the straw can be shred and throw, or lay it into swath.
 

Integrated shredder-thrower

Integrated shredder-thrower provides thorough straw cutting and its uniform distribution over the field surface at preset reaper width. The design uses knives with wear-resistant edges having self-sharpening effect.

READY FOR ANY TASKS

ACROS harvesters are equipped with YaMZ and Cummins 6-cylinder reliable engines thoroughly selected in respect of power and torque moment. Torque reserve of 20% guarantees that ACROS will reliably perform its operation in any harvesting situation.
 

Does not require too much

Minimum fuel cost is another condition of high-effective harvesting, which has been taken into account when choosing the engines for ACROS.

Due to application of compact 6-cylinder YaMZ aggregate, the fuel specific consumption is reduced minimum by 5%, and, when using Cummins engine – by 15%. Economical engine together with 540L fuel tank allow to work up to 14 hours without refueling.
 

The correspondent frontal equipment is required for such high-efficient harvesters. Everybody knows that the harvesting starts from reaper. Therefore, the selection of right decision represents the most important aspect when selecting the harvester.

The reaper hydraulic drive

allows to adjust its rpm without gears providing optimal and uniform mass feeding for the high productivity purpose. It is easy and reliable mechanism with minimal adjustments.

Reaper rpm and harvester drive speed synchronization system

makes easier the harvester operator’s work, and reduces the requirements to his qualification. As the result, increased harvesting productivity and reduced losses. Connecting areas of the reaper beams and rake elements are reliably protected from winding of long-stem plants.

Schumacher cutting apparatus

operates smoothly, precisely and without wear. High cutting rpm and increased travel of knives increase the cut quality and, respectively, the harvesting productivity, especially in adverse conditions. The knives are attached with bolts, what considerably reduces the time of their replacement. In order to harvest the laid crops on uneven soils, the stem-lifters, which preliminary lift the stems fromground, are used to reduce the losses (included into basic set).

The large diameter worm

prevents the winding of high-stem crops. Pins between the worm threads arranged along the coverage width promote the mass feeding even when harvesting peas and very low barley (for reapers with electrical-hydraulic copying). There are grooves on the pins allowing their careful braking in case of getting the rocks.

In order to harvest the corn seeds, the set of ACROS thresher re-equipment and 6- or 8-row snapper is proposed. The device provides harvesting of seeds with simultaneous shredding and throwing of leaf-stem mass over the field.

The 8- and 12-row reapers especially designed for harvesting the sunflower shall provide the completeness crop harvesting at minimum rate of 98%, what is not achievable when using another type attachments. The reapers reliably operate in any agricultural conditions, including stunted sunflower hybrids.

In order to achieve maximum effectiveness when harvesting the easily-damaged cultures, the additional equipment is proposed. Rape attachment for reapers 6/7/9 m will reduce losses at harvesting by 3-4 times and additionally pick-up 30-100 kg of grain from 1 hectare of field, depending of crop capacity.

When harvesting seeds of legumes and cereals, it is possible to reduce considerably the seed losses and increase their purity, if the harvester will be equipped with special attachment (“piercing” sieves, deck strip, etc.).

In case of separate harvesting, the harvesters are equipped with pickup platforms having width 3.4 or 4.3 m. As the reaper, this device is able to copy the field relief in longitudinal and later directions. Reliable protection of pickup elements from clogging, winding and blowing-off the mass by wind provides its stable operation even in adverse conditions.

For the harvest sparse, undersized bread essential grain conveyor header Draper Stream 900 whith width of 900mm. When using it, the rate of harvesting is increased to 10-15 %, which allows to optimize the download of the thresher. Special wheels, performing the functions of copying field relief and support of the header, may also be moved the transport position, eliminating the need to use transport trucks.
