Hitch Tractor
Crushing Hazard:
Do not stand or place any part of your body between the
implement and moving tractor. You may be severely injured or
killed by being crushed between the tractor and implement.
Stop tractor engine and set parking brake before installing the
hitch pins.
4.
Connect the tractor lift arms to the lower hitch pins. If
using a quick hitch, ensure that the pins lock
securely.
5.
Connect the top link to the upper hitch pin.
Front-to-back leveling is performed in later steps.
Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines.
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Use a piece of paper
or cardboard, NOT BODY PARTS, to check for leaks. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. If an accident occurs, seek immediate
medical attention from a physician familiar with this type of
injury.
Refer to Figure 6
Great Plains hydraulic hoses have color coded handle
grips to help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve are marked with
the same color.
Color Coded Hose Handles
To distinguish hoses on the same hydraulic circuit, refer
to the symbol molded into the handle grip. Hoses with an
extended-cylinder symbol feed cylinder base ends.
Hoses with a retracted-cylinder symbol feed cylinder rod
ends.
Connect fold hoses to suitable tractor remote valves.
