Drill Setup Checks
Hydraulic Bleed
Bleeding the hydraulic system is not a routine daily setup
item. If the system has not been charged since delivery,
or any hydraulic work has been done (such as installing
markers), “Bleeding Hydraulics” on page 145.
Drill Level
Drill sections are aligned and leveled at the factory, and
re-checked during dealer pre-delivery. Level normally
does not require routine adjustment before use. Great
Plains does recommend checking it once prior to first
field use. See “Level Frame Side to Side” on page 142.
Drill Option Setup
Even if factory- or dealer-installed, some optional items
may need checking or adjustment prior to first field use.
Install any that were not pre-installed.
Scrapers (Option)
If scrapers were ordered, and not dealer-installed, install
them now per the instructions in one of the following
manuals, which are available on the Great Plains website
if not ordered or included:
