Rates are intended as a guide only. Variation in seed size and cleanliness will affect rates.

Check acreage and pounds of seed used and calibrate seeding rate per manual instructions for best results.

*Seed cups will crack some seeds at this setting. Not recommended: Lentils, Sorghum, Sudan Grass

Calibrating the STR for unlisted seed or seed blends

Operation 13

acre) per .lbs = 56.43 x .lbs ( .failure component mechanical or down leak hydraulic prevents up

).lbs = 0625. x .oz (

Equipment

You will need the following equipment to calibrate your seeder.

1.Two jack stands.

2.One to two pound sample of seed.

3.One tarp or canvas approximately 48" x 84".

4.One scale capable of measuring ounces or tenths of a pound.

Procedure

1.Evenly distribute seed in the bottom of seed box.

2.Raise STR just enough to lift rear roller spikes off the ground and securely block the rear corners of the frame with jack stands. Blocking

3.Place a canvas or trap under STR to collect seed.

4.Open seed cups half way and lock into position.

5.Turn rear roller in the direction of travel the number of revolutions as indicated in the Formula section.

6.Weigh the collected seed and calibrate.

7.If seed rate is not correct, repeat steps 1 through 6, after adjusting the seed cup opening.

Formula

Revolutions per 1000 sq. ft.

STR48 - 87

STR72 - 58

Weight of collected seed

Seed per acre

Example

STR48 rear roller was rotated 87 complete revolutions in the direction of travel as specified above. Collected seed weighed 10 ounces or .63 pounds (10 oz. x .0625 = .63 lbs). Seed rate was calibrated at .63 lbs. x 43.56 = 27.4 lbs. of seed per acre.
