How do you set combined sieves?

The front third of the upper sieve should be completely clean. The middle section should carry a mixture of grain and crop residue. The rear third should carry only trash. If the sieve is totally covered, increase the fan speed.

How many pounds per acre do you plant buckwheat?

A general recommendation for seeding rate is 700,000 plants per acre, which is about 50 to 55 pounds per acre of large seed or about 40 pounds per acre of small seed. Buckwheat can compensate somewhat for a thin stand by branching more, and as a result studies show little yield response to seeding rate.

How do you windrow buckwheat?

You can either dry buckwheat in windrows, so that the frost and cold weather of autumn can dry out the more mature seeds, or bring the crop in directly from the field. Cut stalks, tie them into bundles or shocks, and dry them until the seed head has a moisture level of no more than 16%.

How late can you plant buckwheat?

Right Time to Plant Buckwheat. Buckwheat is a fast-growing plant that begins to flower four weeks after it is sown and produces grain in 10 to 12 weeks. It can be planted throughout summer until mid-August. If planting buckwheat as a cover crop, it can be planted in late spring or early summer.

What do sieves do on a combine?

Sieves, along with shoe shake, are designed to walk the material out the back of the combine, scalping the seeds out as the material shakes across the sieve. The airflow directed to the sieve by the fan is intended to blow hulls, chaff and short straw out of the combine.

What is a chaffer sieve?

The chaffer sieve should allow all grain and unthreshed cobs/pods/heads through. The shoe sieve below should let only threshed grain through, so that the unthreshed portion goes to tailings and is returned to the rotor cage to be re-threshed. If the chaffer setting is too open, it overloads the shoe.

How deep do you plant buckwheat?

Plant buckwheat after all danger of frost. In untilled, minimally-tilled or clean-tilled soils, drill 50 to 60 lb./A at 0.5 to 1.5 inches deep in 6 to 8 inch rows.

What animal eats buckwheat?

Honey bees aren’t the only wildlife to enjoy buckwheat. Rabbits and deer also like to feed on buckwheat, and wild turkeys will eat the seeds. Butterflies will also enjoy a buckwheat crop.

Will buckwheat grow in shade?

Buckwheat does not require a well-prepared seedbed, but I recommend it where possible. Also, buckwheat is not shade tolerant, so plant in food plots that have full sunlight most of the day. Buckwheat does best with soil that tests at a pH of 5.5 – 6.0.

Does buckwheat come back every year?

Buckwheat is a fast-growing, warm season annual. When to sow seeds outside: RECOMMENDED. 1 to 4 weeks after average last frost, and as late as 10-12 weeks before first fall frost; can succession sow every 1-4 weeks.

How do I stop sieve losses?

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 is concave clearance?

Cylinder and Concave Clearance: The gap between the tip of the cylinder to the inner surface of the concave expressed in millimeters. The minimum and maximum clearance in a particular setting and adjustment range for both the front and the rear side of the concave shall be stated.

How to improve grain loss with John Deere s-series combine?

With your S-Series combine from John Deere, it’s possible to reduce grain loss in a short amount of time. Doing so can ultimately help you make the most of your efforts and improve yield. Let’s take a look at how you can potentially reduce grain loss with your John Deere S-Series combine on the job.

What to plant after harvest after growing buckwheat?

After growing buckwheat, either corn or soybeans can be planted. A particularly effective soil health approach would be to grow winter wheat (or winter canola or potatoes), followed by buckwheat. Right after buckwheat harvest, cereal rye could be drilled and serve as a cover until soybeans are planted the next spring.

What do you call the hull of a buckwheat seed?

Buckwheat grain or seeds have a hull, somewhat similar to a sunflower seed hull, that is normally removed before the seeds are used in foods. The dehulled portion of the buckwheat seed is referred to as a groat.

What kind of nutrients does buckwheat have in it?

Buckwheat is relatively high in protein, fiber, Vitamin B6, iron, and magnesium. It also has significant levels of other minerals such as zinc, copper, and manganese.

How do you set combined sieves?

The front third of the upper sieve should be completely clean. The middle section should carry a mixture of grain and crop residue. The rear third should carry only trash. If the sieve is totally covered, increase the fan speed.

What is the concave on a combine?

It is the process of freeing the grain from the chaff. Combine concaves are used to filter grain and small straw in the treatment of grains such as rice, corn, etc. Among the components of a combine harvester, concave is located near the front of the machine, underneath a threshing cylinder.

What does STS stand for on John Deere combines?

Single Tine Separator
The Single Tine Separator )STS) is the heart and soul of the most productive combine on the market, the John Deere 9860 STS. John Deere’s 1999 introduction of its 50 Series Combines – featuring the Single Tine Separator (STS) – represented a bold step forward in harvesting technology for the company.

When did John Deere make a rotary combine?

Somewhere in the early sixties, Deere dropped their all-out efforts to produce a rotary combine, even though some experimentation continued right up until the time the 4400, 6600 and 7700 were introduced in 1969. In 1975 New Holland introduced their TR70, the first rotary by a major manufacturer.

What does CTS mean on John Deere combine?

CTS is an acronym for Conventional Tine Separation. These are exceptional cereal combines and through no grain over with the straw. With at addition of the Precision rear beater upgrade they will keep up with 9610 in Canola as well.

What should concave module clearance be on 88 series combine?

Of course if the soybeans dry down during the day, you will reevaluate rotor speed. Concave module Clearance: Depending on the vintage/model of the combine, this can be different. The new 88 series calls for 15 to 25 MM. Other models might say 3 to 4 on the indicator.

What should the rotor speed be on a corn combine?

By having the back 5 vanes in slow position (along with the 8 straight bars on the back of the rotor), this will pretty much eliminate any chance of rotor loss in high yielding corn. Rotor Speed: Baseline is 350 to 450 RPM. A lot of folks like 380 to 400 RPM.

What are the maintenance troublespots on a combine?

Maintenance troublespots Particular wear points on a combine that often demand attention are any parts experiencing repeated friction, like the roller chains on a corn head. With any chain that has noticeably loosened, stretched, or become “sloppy,” the likelihood that part will last through harvest’s end lessens.

What’s the best rpm to run a combine at?

(If you slow the rotor in an effort to control rotor loss, It is suggested not to run less than 300 RPM. Because at this low speed, you do put a lot of torque/load on the rotor belt. Concave module Clearance: Depending on the vintage/model of the combine, this can be different.
