Seed And Fertilizer Adjustor Gearboxes

Seed And Fertilizer Adjustor Gearboxes
For the machines without fertilizer, there is only Seed adjustor gearbox.

As for the machines with fertilizer, there are two adjustor gearboxes.

When you look at the machine from behind of it
- Seed adjustor gearbox is on the RIGHT side.
- Fertiliser adjustor gearbox is on the LEFT side.

Altough these two gearboxes look similar, they cannot be substituted because of the structure of control levers.


Duty of the gearbox is to adjust the rotational speed of seed and fertilizer shafts and accordingly amount of seed and fertilizer planting by means of increasing and decreasing circuit (cycle) value coming from movement wheel through chain and gear within a certain range.This process is performed by means of shifting the control lever of transmission over the adjustor sheet varying between 0 and 100.

When control lever is positioned on 0, movement of gear pin and gears commanded by transmission will STOP. If it doesn’t stop, there is a problem. Get contact with authorized service.

When control lever is positioned on 100, it means that gear pins and gears turning at maximum.


Adjusting Amount of Seed and Fertilizer Planting

As intensity and surface smoothness of seeds can vary from region to region, from type to type and over the time, we don’t approve to say that values on the adjustor sheet of transmission means certain kilograms of seed will be planted per hectare. In addition to this, the best method is to make adjustments again every season and for each different seed because a wide range of sort of seed can be planted by means of this product and there are other adjustment mechanisms such like valve, shutter cover which have influence on amount of planting. The same situation is valid for fertilizer adjustment. Experiences can ease this process but we emphasize that you shouldn’t take only experiences into consideration for the precise adjustment for amount of planting.

Seed And Fertilizer Adjustor Gearboxes

The following processes should be carried out in order to examine how much seed can be planted per hectare in which position of transmission:

- Fill in seed hopper with seeds to be planted.

- Determine position of gear according to sort of seed and make adjustment accordingly.

- Open shutter covers as much as needed.

- By means of valve control lever, bring and stabilize the space between valve and gear to the needed level.

- Stabilize control lever of transmission at any point (or the most appropriate point by your experiences) on adjustor sheet.

- By means of turning the wheels 3-5 times, ensure that craws and gear spaces are fulfilled by seed.

- Insert the test container under the funnels by pulling down the mechanism holding Seed-Fertilizer Tubes.

- Turn the seed movement wheel 20 times (cycles).

- Collect the seeds poured into test container and weigh by the help of precision balance.

- Multiply the weight you found by the coefficient corresponding to your machine into the following table.

- The obtained result presents amount of seed that will be poured per hectare with 5% of fudge factor.

- If this result you found is less than the amount you desired, slide the control lever of transmission so as to rise up to a higher value on the adjustor sheet and repeat the operation until you reach the value you want.

- If this result you found is more than the amount you desired, slide the control lever of transmission so as to rise up to a lower value on the adjustor sheet and repeat the operation until you reach the value you want.

As for Fertilizer Planting Adjustment, FERTILIZER TRANSMISSION WHEEL will be turned (when you look the machine from behind, it will be on the LEFT side) and adjustment will be made for adjustor transmission of fertilizer planting, differently from the process above.

IMPORTANT REMINDINGS

• As mentioned in previous chapters, tire measures on your machine should be checked for correct coefficient when planting adjustor is made. You should use the coefficient on the point where column related to this tire and column related to work area of your machine intersect on the table.

• Seeds that are not cleaned well and are broken will result with bad seed drilling operation. Be careful.

• As for the first entering on field, flowing of seed can be above normal. This can create a difference between the adjustment test you made and actual planting value. In cases of requiring more precision, we recommend to repeat the adjustment test of planting after planting approximately 2-decare place.
