Installation
Attaching to the Tractor
Attach the sprayer hitch to the tractor drawbar
using the tractor hitch pin. Adjust the height of the
tractor drawbar and/or sprayer hitch to level the
sprayer. The hitch on the sprayer drawbar can be
installed in either the high or low position.
To alter the sprayer hitch height, remove the
drawbar attaching bolt and slide the drawbar out.
Rotate the drawbar through 180
0
and reinstall it in
the alternate position. Ensure that the drawbar
attaching bolt is securely retightened.
Clean and grease the splines on the tractor and
sprayer PTO stub shafts and install the PTO shaft
making sure that the spring loaded locking pins
engage in the grooves of both stub shafts. Ensure
that the tractor’s PTO shaft guard is attached to
the tractor.
PTO Shaft Length
Note: Upon delivery of a new sprayer it is the
selling dealer’s responsibility to install and set the
PTO shaft to the correct length. The following
information is provided for reference.
greater than about 10 cm, refer Fig 1.
The hitch point between the tractor and sprayer
should be approximately midway between the two
joints of the PTO shaft and the height difference
between the joints should not be greater than
about 10 cm, refer Fig 1. This will ensure the joint
angles are approximately equal during turns and
do not exceed the allowable limit.
The telescoping tubes must overlap by at least
1/3 their length, but not less than 150mm, in all
possible operating positions and there must be at
least 25mm telescopic movement remaining at
the minimum operating length, refer Fig 2.
The length of the sprayer drawbar can be
adjusted by removing its attaching bolt and sliding
the drawbar in or out to one of the three positions
where the bolt holes align. Reinstall the drawbar
bolt and tighten securely.
The length of the tractor drawbar may also need
to be adjusted.
If the PTO shaft must be shortened cut equal
amounts from both male and female shafts and
safety covers. Carefully remove all burrs then
clean and relubricate before reassembling.
Cabin Mounted Controls
Connect the electrical cables provided directly to
the battery.
Positive =
Red
Negative = Black
If the cable needs to be extended it is important
to use wire of the same diameter. These cables
supply power to the electric valves.
If an automatic rate controllers is used refer to
appropriate installation manuals.
Run the controller wiring loom back to the
sprayer through a convenient outlet in the tractor
cabin, ensuring that it does not rub on any sharp
edge. Connect the tractor loom to the sprayer
loom at the quick release coupling and ensure
that all wiring is clear of the PTO shaft and
tractor wheels.
