4.2 Grain Drill Setup
The 147C Grain Drill may be shipped without the hydraulic lift cylinder, since the grain drill used a standard 3” x 8”
cylinder. The retracted length must be 20-1/4”, measured from the center of the mounting holes. When multiple grain
drills are used, a cylinder will be required for each grain drill.
• Set the wheels on your tractor out as wide as possible for maximum stability.
• Hitch the grain drill to the tractor.
• Connect the hydraulic hoses to the tractor’s hydraulic system.
4.3 Pressure Spring Adjustment
To gain versatility for all types of terrain and soil conditions, it is important to have a considerable amount of up and
down travel built into each individual run. When seeding on level terrain, adjust hydraulic cylinder stroke to lower
Movable Frame so openers penetrate soil approximately two (2) inches and Parallel Bars are about level when viewed
from the side. The toolbar height will be about 20” when discs are new. This will allow runs to move up or down
according to terrain.
If parallel bars are not level, it will be necessary to adjust pressure spring, or press wheel adjustment.
Proper tension of the pressure spring varies with conditions. No-till seeding may require more down pressure; loose
soil requires less. Since the pressure springs work together with the opener depth adjustment controlled by the
hydraulic cylinder, make sure that the opener depth adjustment is set correctly.
