Native Grass Spring Opener
The 5110 native grass drill is equipped with a spring
opener. The opener has two 15.8” x.138” thick opener
blades, a rigid scraper, and adjustable swivel press
wheel.
The spring opener has two spring settings for light or
heavy down pressure
See Figure 4-37 . The lower spring
mounting hole is the heavy down pressure setting, and
the upper hole is the light pressure setting. To change
the spring pressure setting, raise the opener slightly to
relieve the spring pressure. Remove the 1/2-13 x 3-3/4
cross-bolt through the rear of the spring assembly. Move
the spring to the desired setting and reinstall the
cross-bolt.
