How do I stop sieve loss?

Avoid over-threshing. Straw pulverized into small pieces that drop down to the sieves will reduce air flow and separation — and increase losses. Cracked seed is another sign of overthreshing. Consider lowering the cylinder speed or widening the concave setting.

What do Concaves do in a combine?

Combine Concaves Purpose The combine concave performs two important functions- threshing and separating. The threshing process frees the seeds from the plants. Then the separation process moves the seeds away from the chaff.

What is sieve on combine?

The separating portion of a combine is a combination of the cleaning fan, upper sieve and lower sieve. The goal is to “float” the mat of grain and residue across the sieves on a cushion of air so the shaking motion of the sieves allows the grain to fall down through the residue.

What do the sieves do in a combine?

The upper sieve should do the main separating. The lower sieve is for fine-tuning the sample.” Manage residue. Stalk choppers on combines used to be secondary to threshing and separating grain.

How do you reduce tailings in a combine?

Proper rotor speed , concave clearance, fan setting and sieve adjustment will reduce the amount of tailings. Tailings should include only unthreshed particles.

What do sieves do on a combine?

Separate. The separating portion of a combine is a combination of the cleaning fan, upper sieve and lower sieve. The goal is to “float” the mat of grain and residue across the sieves on a cushion of air so the shaking motion of the sieves allows the grain to fall down through the residue.

Are chaffers bottom or top?

Shoe, old term for last stage, on us humans, the “shoe”. We refer to the top sieve as the chaffer and the bottom as the shoe.

How many engine hours on a John Deere 6600 combine?

John Deere 6600 combine. 3765 engine hours,with straw chopper. Came right off a local 100 acre farm. You’ll go a long ways to find another one this nice and clean. Absolutely zero rust,stored inside.

How do I get the best results with my John Deere combine?

To achieve the best results we must ensure that the John Deere Combine settings are carried out properly and systematically. John Deere combine, as the name indicates, is not a single machine but a number of machines working as one unit and carrying out different aspects of harvesting in an efficient manner.

What is a grain stage on a John Deere combine?

In the John Deere Combine settings for soybeans, • The standard header can be called as the grain stage which has been assembled with the blade shaper bar with a full response. The plastic teeth or rotating reel is in the highlight which allows cutting the yield and fall directly into the twist drill after it is cut.

What kind of engine does A 6602 combine have?

The 6602 sported either a 362 gasoline or a 404 cubic inch diesel engine; each was able to produce 121 horsepower. This additional horsepower was needed in the machine because it had to run an extra pair of hydraulic cylinders. These cylinders leveled the combine as it traveled down the field and were controlled by an air-dampened pendulum system.
