ber 117-041A, from your Great Plains dealer.

•
Use the threaded link to adjust your drill so it runs hori-
zontal to the ground when drilling.
•
The telescoping link allows your drill to float front-to-
back and follow the ground contour.
When hooking up to the drill, be sure the quick hitches are
latched securely.
Hydraulic Hookup
Great Plains hydraulic hoses are coded to help you hook-
up to your tractor outlets. To distinguish hoses on the
same hydraulic circuit, refer to plastic hose holder. See
Figure 1-6. Connect hose under extended cylinder to out-
let you choose for cylinder extension. Connect hose under
