5WPMAN0100 (Rev. 5/2/2008)
Equipment
You will need the following equipment to calibrate your seeder.
1. Two jack stands.
2. One to two pound (0.5 - 1 kg) sample of seed.
3. One tarp or canvas approximately 48" x 84" (1.2 m x 2.1 m).
4. One scale capable of measuring ounces or tenths of a pound (grams or
tenths of a kilogram).
Procedure
1. Evenly distribute seed in the bottom of seed box.
2. Raise overseeder just enough to lift rear roller spikes off the ground
and securely block the rear corners of the frame with jack stands.
Blocking up prevents hydraulic leak down or mechanical component
failure.
3. Place a canvas or tarp under overseeder 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.
Calibrating the Overseeder for Unlisted Seed or Seed Blends
7. If seed rate is not correct, repeat steps 1 through 6, after adjusting
the seed cup opening.

Example
(Metric formula in italic)
TR1048 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.
TR1048 rear roller was rotated 93.6 revolutions in the direction of travel
as specified above. Collected seed weighed 4000 g or 4 kg (4000 g
÷
1000 = 4 kg). Seed rate was calibrated at 4 kg x 48.9 = 195.6 kg of seed
per hectare.
