HOOKUP AND OPERATION
Hydraulic Gate & Push-Off Wall
System
1.
The hydraulic system will be filled with oil and fully
charged. Carefully hitch the AG11/AG13 to the
tractor and connect the hydraulic lift hoses. Check to
make sure the tractor hydraulic reservoir is full of
the manufacturer’s recommended oil. Complete a
gate/push-off wall cycle to verify that the system is
operating correctly. Recheck tractor reservoir to
make sure it is within operating limits. With the gate
cylinders fully retracted, install the gate lockout.
Figure 4-4: Gate Lockout
2.
Before entering the bowl for any reason, ensure that
the gate lockout is in place. Failure to take this
preventive measure could result in serious personal
injury.
3.
Always fully retract gate cylinders before removing
gate lockout. Unit can settle during maintenance
causing the lockout to be pinched.
4.
The AG11/AG13 gate and push-off system is
controlled by a sequencing manifold, allowing 2
functions to be operated by only 1 hydraulic valve
on tractor. See
“Sequencing Manifold Adjustment”
General Operation
1.
The horsepower requirements are typically 250-400
horsepower. This will vary widely due to speed, depth
of cut, moisture and types of soils. Additional
horsepower will shorten the life of the unit. Local
dealers can help in making recommendations for
your areas.
2.
Loading speed is typically 4-8 mph depending on the
type of soil/material being loaded. Excessive speed
can cause the unit to bounce and create an uneven
cut depth, too low of speed will not allow the bowl to
be loaded effectively.
3.
Do not turn sharply with the AG11/AG13 in the
ground, this can put excessive side load on the entire
unit. Raise the unit slightly when making sharp turns
to prevent gouging and/or ridging of material.
Field Operation
1.
Raise the unit to take the weight off the transport
lockout. Remove the transport lockout from the lift
cylinder and reassemble it in the storage location.
2.
Cycle each hydraulic function to ensure they are
working properly.
3.
Be patient for the first few hours of learning to
operate the machine. Time and experience will
produce expert results. Any type of cutting-edge
machine will have the tendency to create a
“washboard” effect, if too much speed and
inconsistent depth is used.
4.
To help prevent this “washboard” effect, slow down
and take a lesser and more uniform cut per pass.
This may increase the number of passes needed to
achieve a certain cut depth but will increase the
quality of finish.
5.
Different soil types and conditions may require
different operating techniques. Take your time and
find what technique works best for your current job
site.
6.
If the machine is used to “back level” or drag, be
certain that the gate is fully raised and the push off
wall is completely forward. This allows the operator
to carry a small amount of material to fill with (if
needed.)
Important: Never use a closed gate for
bulldozing or grading material.
7.
A visual depth gauge is located at the right side,
front of the machine. It allows the operator to set
the cutting edge to the proper depth for a uniform
cut or eject depth of the load.
