“ChangeSep” interchangeable separator and windrower awarded silver medals at Agritechnica
- For the first time, the ChangeSep separator from Grimme now enables tool-free switching between two active separating facilities for tuber-like foreign objects in a harvester
The manufacturers of hauled bunker harvesters offer their models with different foreign object separating facilities to enable adaptation to the prevailing operating conditions. However, internal field-to-farm distances and therefore also frequently the variability of the soils are increasing as the cultivation areas of potato-producing farms continue to grow. In practice, this leads to the circumstance that an unsuitable separator is used on an increasing number of fields.
For the first time, the ChangeSep separator from Grimme now enables tool-free switching between two active separating facilities for tuber-like foreign objects in a harvester. This therefore allows the rubber finger web separating facilities, which are designed as circulating scraper or deflector rollers, to be quickly and easily adapted to changing soil and harvesting conditions as well as different harvesting methods (direct, split or enriched). This saves a vast amount of (conversion) time and establishes the prerequisites for optimising the work rate without forgoing gentle handling of the tubers.
With the ChangeSep interchangeable separator, Grimme has combined two existing systems in a single machine, therefore significantly evolving separator technology, particularly because the separators can be changed with little effort and without special technical equipment.
As small-scale potato-growing areas become increasingly mechanised in emerging and developing countries, the quality of work during harvesting is gaining in importance in addition to the work rate.
A windrower jointly developed by Shaktiman and Grimme is meeting these demands with a new machine design. Thanks to a short first sieve chain and the hydraulic folding mechanism for the second sieve chain, coulter depth control by means of ridge rollers can additionally be integrated into the machine without significantly increasing lifting power requirements, thereby ensuring that the existing small tractors can continue to be used. The depth-controlled intake section and the enlarged sieve area enable an adjusted flow of material that is gentle on the tubers through the windrower. At the same time, the placement of the completely exposed tubers onto the roller-compacted soil makes the work of the harvesting staff significantly easier and therefore lastingly reduces the extensive losses caused by concealed potatoes.
On the whole, this crucial further development of the familiar windrower system contributes to an increase in both work quality and the work rate and therefore to food security for the population in emerging and developing countries.
