Tractor Connection
Prior to tractor to sprayer connection, it is important
that the operator has read and fully understood this
operator's manual.
TRACTOR TO SPRAYER CONNECTION
1. Ensure that the tractor is suitably rated to safely
tow the sprayer and that the drawbar pin size
matches the hitch on the sprayer. The standard
hole size is 50mm. A replaceable insert (Part
number GA4582455) can be purchased to
reduce wear if required. A replaceable bush
(GA5075075), reduces the size of the hole in the
hitch if a smaller pin is to be used.
2. With the sprayer parked on a level surface, use
the sprayer jack to raise the sprayer hitch in line
with the tractor hitch.
3. Reverse the tractor into sprayer hitch until
aligned, and insert drawbar pin (not supplied).
Then connect safety chains.
4. With the sprayer securely attached to the tractor,
raise the jack until weight is transferred to the
tractor. Then raise the jack and store in the
transport position.
5. Fit the PTO shaft (if applicable).
• Grease the PTO shaft as per the lubrication
schedule
• Ensure that all safety guards and chains are in
place
NOTE: It is important that the instructions 'PTO
Shaft Fitment' are followed for first time setup.
NOTE: The wide angle joint must be connected to
the tractor PTO shaft.
Hydraulic Drive Spray Pump
Diaphragm pumps can also be driven by a hydraulic
motor which is bolted directly to the front of the
pump.
The oil line to the hydraulic pump is fitted with a
needle valve that regulates oil flow to the pump.
Many tractors feature hydraulic oil flow regulation in
the cabin, however this needle valve can be used to
control the flow on tractors that are not fitted with
hydraulic oil flow regulation.
24 - Chapter 7 - Pre-Operation
For hydraulic drive pumps - connect hydraulic hoses
to tractor remote outlets. See to chapter 3 'General
Information & Specifications' for important hydraulic
information.
6.
Fit the spray controller and any other switch
boxes supplied in tractor cabin. Make sure that
all controllers and switch boxes are securely
mounted.
7.
Connect any power leads from Raven Console
directly to battery.
8.
Connect drawbar connections.
All hydraulic hoses except two, have a tag zip tied to
them that denotes what they are for. Connect the
hoses to the appropriate place on the tractor. Ensure
that the connection points are clean before fitting to
the tractor.
The two hydraulic lines that don't have tags on them
are the pump lines. The pump can run in either
direction so it does not matter which port (pressure
or tank) that the hoses go into.
If the sprayer is not fitted with spool valves, it is very
important that the hydraulic lines are connected in
the correct pairs to the tractor remotes.
If not already done, apply some dielectric grease
to the electrical connections. Such as to the wiring
loom, speed sensor cable, tail light plug and so on.
Then connect them to the appropriate plug at the
rear of the tractor.
Disconnection of the sprayer from the tractor is the
reverse of the above instructions.
Where the tractor has the capability to regulate
flow from the cabin, it is recommended to close the
needle valve and adjust the hydraulic oil flow from
the tractor to set the pump running at 400 - 500
rpm. Do not exceed 540 RPM.
SETTING HYDRAULIC PUMP SPEED
See Chapter 6 'Calibration' for more detailed setup
information when a Raven SCS450 console is used
to control the hydraulic spray pump speed.
