There is an infinite set of adjustments available on this machine and care should be taken when adjusting parts of the machine. It is advisable only to alter 1 setting at once so to avoid confusing what is happening with the machine.<\/p>\n
This has the most pronounced effect in terms of separation. Generally speaking the faster the spirals turn the less the machine will separate (ideally between 120 and 130 RPM). The aim is to run the spiral shafts at the minimum speed to achieve maximum separation without loss of the crop.<\/p>\n
To help achieve this it is possible to run the clod rollers at different speeds: faster for maximum extraction, and slower for less separation (this can be as little as 30 RPM).<\/p>\n
The clod rollers become more aggressive at separating when they are in a higher position and much less when lowered. When separating large particles such as clods of earth, a higher position for the clod roller allows such debris to stall for a while which will allow the flutes of the spiral rollers to grind down the clod.<\/p>\n
The gap adjustment is also critical and once set to a minimum will eliminate the loss of a small crop such as salad potatoes or baby carrots and dramatically improve self-cleaning on sticky soils.<\/p>\n<\/div>\n

Clod roller direction<\/b><\/p>\n
For root crops such as carrots parsnips, onions, shallots, bulbs etc we recommend that clod rollers run in the same direction as the spiral rollers.<\/p>\n
On main crop potatoes generally 2 or more of the clod rollers can be reversed, this will allow haulm to be extracted and larger clods depending on the level of debris.<\/p>\n
In Summary (for contra rotating)<\/h4>\n
Maximum separation<\/b><\/p>\n\n- Reduce speed of spiral rollers<\/li>\n
- Increase speed of clod rollers<\/li>\n
- Lift clod rollers up<\/li>\n
- Increase gap between spiral and clod roller (Can reduce self-cleaning in wet conditions)<\/li>\n<\/ul>\n
Minimum separation<\/b><\/p>\n\n- Increase speed of spiral rollers<\/li>\n
- Decrease speed of clod rollers (or change direction to forward)<\/li>\n
- Lower clod rollers<\/li>\n
- Decrease gap between spiral and clod roller<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
