A.After considering the site to be seeded (shape, soil texture, slope, obstacles, etc.), set your tractor ground speed (MPH). Select a gear setting that will provide the desired MPH and maintain a PTO speed between 500 and 600 RPM or as required for the degree of tillage desired. The ground speed can be verified by determining the time required to travel a distance of 200 ft. per the following speed/time chart:
Speed MPH | Time Required | Speed MPH | Time Required | Speed MPH | Time Required |
| per 200’ |
| per 200’ |
| per 200’ |

| 2 ½ | 55 sec | 4 ½ | 30 sec |
1 | 2 min 16 sec | 3 | 45 sec | 5 | 27 sec |
1 ½ | 1 min 31 sec | 3 ½ | 39 sec | 5 ½ | 25 sec |
2 | 1 min 8 sec | 4 | 34 sec | 6 | 23 sec |
B.Fix the preliminary cam gauge setting for your selected seed using your best judgment.
C.Collect and weigh the seeder output for 1000 sq. ft.
a.Place seed in hopper with control lever closed.
b.Place empty container on one of the spouts to catch seed (To prevent loss of seed, block off other spouts).
c.Start motor
d.After waiting 15 to 20 seconds, open the control lever for the time required to travel 200 ft. that corresponds with the set speed (see speed/time chart).
e.Close the control lever after it has been open the exact time required.
f. Weigh the collected seed and multiply times 23 for total output and compare to the desired rate per 1000 sq. ft.
g.Adjust the cam gauge and repeat the procedure as required.
