Adjustments for Vine Cutting disC
Center coulter is to cut plastic in half for easier re-
moval. With most crops, the center coulter is very helpful;
plastic will pull away easier when split in half.
Avoid adjusting it too deep.
Note: Center coulter can also be removed if not needed.
Discs need to cut vines but not plastic.
Adjust side discs in line with the lifting shanks.
Note: Top link can be lengthened to avoid front disc
from cutting too deep. Setting discs too deep will keep
machine from going down.

Depth Wheel Adj.
Slide up 6” to 8” before use.
depth Adjustment
Depth wheels need to be adjusted so that top of plow
share stays approximately 4” to 6” below the plastic. Adjust
lifting prongs to proper height that will lift plastic, but not
too high that it will restrict plastic ow.
Note: Running machine too shallow may cause vines to
drag or clog up plastic ow.
Top of Share Bracket
Keep 6” to 8” below plastic.

plAstiC Width Adjustment
Adjust shanks approximately 6” wider than each side of
