Cutting Depths for Height Adjustments:
The Dirt Doctor junior has been designed with four height positions for the pulverizer bar and three height positions for
the ripper bar to allow for different surfaces and soil conditions. Adjusting the pulverizer bar can also regulate the cutting
depth of the ripper bar.
Approximate Depths:
Pulverizer Bar in 1
st
(bottom holes) position with:
Pulverizer Bar in 2nd position
- Ripper blades in lowest position
1/4”-1/2” deep
- Ripper blades in lowest position
1” deep
- Ripper blades in middle position
0” deep
- Ripper blades in middle position
0” deep
Pulverizer Bar in Middle 3rd position with:
Pulverizer Bar in 4th (top holes) position with:
- Ripper blades in lowest position
1.75” deep
- Ripper blades in lowest position
2.5” deep
- Ripper blades in middle position
3/4” deep
- Ripper blades in middle position
1.5” deep
Ripper Blades in Highest (top holes) position: (This position is also recommended for transport)
- Non-cutting, unit rides on Pulverizer bar only. Depth will be .5”- 1”. This position is also excellent
for just ‘refreshing’ the surface when infields have a high level of infield mix.
Some experimentation will be needed to achieve the correct results for your particular soil and application.
Adjusting Ripper and Pulverizer Bars:
- Use the tongue jack to raise the front of the unit to adjust the Ripper blades and Pulverizer bar.
- The Ripper blades are adjusted by pulling the Hitch Pins on either side of the unit and moving ripper bar up or down.
The ‘Full Up’ position is used for transport or non-cutting.
- The pulverizer bar height is adjusted by pulling the ‘T’ handle pins with push buttons on either side of the unit and
using the height adjustment lever to move the pulverizer bar up or down. Choose the height position you want and
depress the center button on the ‘T’ handle pin and insert it in the proper hole.
CAUTION:
Make sure the ‘T’ pin engages the hole in the pulverizer bar plate. If the ‘T’ pin is not in the hole, but is
in front of, or is in back of the plate, serious damage to the bar will occur when using the unit.
NOTE:
After each adjustment, adjust the drag chain length so that the drag will contact surface, but will not in-
terfere with roller.
Also:
The center drag section direction may be reversed. The expanded metal section has an angle or ‘slope’ that
makes each small opening act as a miniature cutting blade. The drag section will act less aggressively if you disconnect
the chains and turn the center section around so angle faces rearward.
