PRODUCT IDENTIFICATION & SPECIFICATION
CROPLANDS TRAYMOUNT SPRAYER
Whenever possible, use the serial number of the Traymount
sprayer when requesting service or parts information.
Where a serial plate is not provided or is no longer on the
unit, use the part number from the bar code affixed to this
manual or the Warranty & Pre-delivery booklet.
SPECIFICATIONS
Tank
The Croplands Tray mount range of tanks is constructed from
a UV stabilised, medium density polythene for low distortion
qualities and impact resistance. A screw down main lid is
installed on all models and comes standard with a basket
strainer. A hand wash tank is fitted standard for operator
safety and can be used to clean the suction filter in the field if
needed. A deep sump provides excellent suction and allows
the tank to completely drain.
Pumps
Croplands uses positive displacement diaphragm pumps –
either 12-volt powered for smaller models, or petrol powered
higher capacity AR pumps?. The size and output of pumps
vary depending on the machine specifications ordered.
The pump model and pump serial number is located on the
pump itself. The plate shows the name of the manufacturer,
type and model of the pump, serial number, maximum
working pressure and other requirements. For further
information on parts for your pump, refer to the parts section
on the Croplands website. Use the pump model as the
reference.
Hose reels
Croplands Tray Mount Sprayer range is available with either
- 30 meter hose reel and Turbo Gun 400.
or
- 12-volt auto retractable RetraSpray reel with 100m of
non kink hose and Turbo Gun 400.
Controls
Standard on the 12-volt models is a pressure regulator
mounted on the pump outlet to regulate pressure & flow.
Liquid not required for the boom or reel is bypassed back
to tank. A pressure gauge is provided. 12-volt pumps are
considered to be intermittent duty cycle pumps and extended
operating periods will trigger the thermal overload switch.
The motor must be allowed to settle to a lower (ideally
ambient) temperature before recommencing operation.
An electric on/off switch is provided in the power loom.
On the models with an AR petrol powered 25 or 32 L/min
pump, the pressure regulating valves is either mounted on the
pump, or remotely operated with hoses provided to go to the
towing vehicle. This regulating PRV has taps for boom or hose
reel control and a pressure relief system.
Manuals
Separate manuals for the motor/pumps and (where used)
RetraSpray units are supplied along with the unit.

SECTION 4A
PRE-OPERATION, MOTORISED MODELS
See section 4B for 12-Volt models.
RETRASPRAY
See separate manual for the 12-volt Retraspray retractable
reel and its operation.
UNLOADING
Take care when loading / unloading these sprayers. These
sprayers are well past the capacity for one or two people
to manually handle. Most models have either forklift or sling
pickup points. Be careful of the balance.
All loading / unloading should be done with tanks empty.
See Section 5 of the Safety manual.
FITMENT
Make sure the unit is securely fastened. In many cases this
will involve bolting the unit to a vehicle. Remember to factor
in the weight of a full tank when determining the mounting,
and always consult the vehicles manual for load ratings and
suitable mounting points.
HOOKUP
Retraspray models will require hook up to a suitable 12-volt
power source. See the Retraspray manual.
Connect & route a drain hose to a convenient and safe place
for draining the tank. See below.
DESCRIPTION OF THE PLUMBING
There are 3 configurations of the plumbing for the motorised
pump sprayers – dependant on the choice of pump.
• The AR252 pump models are identified by the large red
plastic pressure regulator.
• The AR30 & AR 40 pump models are identified by the
all metal pressure regulator.
• The AR70 pump model is designed for use with a spray
boom and feature a remote pressure regulator.
The operating principles for both are very similar. See below
example using AR252 pump.
A. The suction line from the tank, to the ball valve.
B. Ball valve. To the left (as shown) is drain, to the right is to
the pump. Vertically up is OFF.
C. Suction Filter. Check and clean frequently, and especially
at the commencement of any spray program (best
checked before chemical is added).
D. Pressure Regulator – and surplus flow goes back to tank
via (E) to aid agitation. The regulator also includes the
pressure gauge.
E. Return to tank. This line is also used for agitation.
F. Spray line to the hose reel (s). Includes an on / off tap.

Note the ball valve has 3 positions, with vertical up as OFF.
It’s suggested the user connect a hose to the drain side of
the valve and route the hose to a convenient place for safe
draining of the tank.
• Be careful to dispose of any chemical in an
environmentally responsible manner.
AR252 Pressure Regulator (ARGR30)
The top portion of the Pressure regulator (red arrow) is used
to set the pressure required. Turn clockwise to increase the
pressure and anti-clockwise to decrease the spray pressure.
Note the AR252 pump is rated to a maximum of 25 Bar
pressure.
In the example shown the non-spraying pressure has been set
to 12 Bar (green arrow). Take note of where the maximum
of 25 Bar is located on the pressure gauge (in the green
sector).
To bypass the pressure line & /or send spray / agitation back
to tank, rotate the lower level of the pressure regulator to the
position shown (yellow arrow).
Note in these 2 photo’s the spray line tap is in the off position
(blue arrow).
AR30 / 40 Pressure Regulator (ARGI40)
In the example shown the regulator has been set ready to spray
(level arm is down) and the pressure has been set to 18 Bar.
The regulator has 2 places for pressure adjustment.
Course adjustment is via the wire / notches – see the
(purple arrow).
Use positions ….
1 for up to 10 Bar,
2 for up to 20 Bar,
3 for up to 30 Bar,
4 for up to 40 Bar.

GP-OMTRAY-A
16
SECTION 4A
PRE-OPERATION, MOTORISED MODELS
See section 4B for 12-Volt models.
Fine adjustment is via the brass knob. Disengage the PRV lever
(see green outline) before adjusting the brass knob as
pointed, Up (increase pressure) or Down (decrease pressure).
Disengaging the lever also activates the bypass / “dump” to
tank / agitation.
Note the AR30 & 40 are rated to a maximum of 40 Bar
pressure which correlates to the top of the green sector of the
gauge. Never operate in the yellow or red sectors.
AR70 Pressure Regulator (ARUCM-5)
The US500/70/HR30TG uses the ARUCM-5 remote 5-way
controller more suited to operating a boom. In addition to the
rotary (red) knob for pressure adjustment are 4 boom on /
off section valves and a master “dump” to tank valve.
ARUCM-4 shown.
Agitation
Note the volume of agitation from liquid bypassing the
regulator (whilst spraying) is determined by the difference
between pump performance (pressure) and the selected
spray pressure.
SPRAY GUN
Motorised Traymount sprayers are supplied with the Turbo
400 Spray Gun, with 1.5mm nozzle.
Practice the operation of the gun with fresh water before
undertaking any chemical spraying.
Controls are a hand-held trigger, side lever for spray pattern
(red arrow) and sliding / adjustable cone.
The side lever is used to adjust for cone or straight stream
spray. Slide the orange cone forwards for a “fogging”
type spray.

17
FILLING, FILTERS & DRAINING
It’s important to keep all filters clean. A careful, common sense
approach to water quality, mixing of chemicals and care of
filters, hoses and tank will ensure trouble free spraying.
Filling is via the lid, filtered via the basket – be very careful to
not splash chemical when filling.
Draining is via the ball valve, with the tap pointing to the left
(as shown). It’s suggested the user connect a hose to the drain
side of the valve and route the hose to a convenient safe
place for draining the tank.
• Take care to dispose of chemical in an environmentally
responsible manner.
Suction lines are fitted with a filter. The type, size and mesh
vary from model to model. All meshes are colour coded
and, in most cases, alternative mesh sizes are available via
spray shops.
Red = 32 mesh (course) - not used from the factory.
Blue = 50 mesh
Yellow = 80 mesh
Green = 100 mesh (fine)

PREOPERATION CHECKLIST
Before operating the sprayer:
• Familiarise yourself with all supplied manuals.
• Check the sprayer is securely mounted.
• Check that the spray tank is clean, and drain tap is
not open.
• Check that the suction line filter is clean.
• Check the hose reel / spray gun or Retraspray unit is
correctly installed. In the case of Retraspray units, connect
the sprayer power leads to a 12-volt battery (see separate
the Retraspray manual).
• Fill the hand wash tank (if fitted) with clean fresh water.
• Check all plumbing and fittings are tight and not
damaged. Fill the sprayer tank with clean water -
making sure the basket filter is in place when filling.
Check for leaks.
• Safety Manual … has been read, understood and
appropriate preparations have been implemented.
INITIAL STARTUP PROCEDURE,
MOTORISED SPRAYER
Always use fresh water for familiarisation, maintenance,
testing or training. If the unit has seen chemical, always wear
safety gloves (as a minimum precaution).
Engine & pump check:
The Honda GX200 engine will have been pre-checked for
operation at the factory. However, it is recommended you
check the oil level as per the Honda manual.
Check the oil level in the pump. Pumps, oil requirements and
fill positions vary from model to model – check the manual
supplied for each unit.

19
Familiarize yourself with the engine controls – choke, on/off,
engine speed control and starter pull-chord.
First Time Start-up
This example is with AR252 pump model. The routine steps are
the same – controls will vary from pump to pump and PRV.
• Oil checks done, correct & adequate fuel.
• Fill the sprayer with some clean water (50 litres would
be sufficient for initial familiarisation).
• Set the PRV to “Bypass” lever as shown (yellow arrow),
and ball valve to the reel in the off position, as shown
(blue arrow).
As a starting point set the PRV pressure adjustment knob to
approximately 4 turns UP (low pressure). All units are tested
and adjusted at the factory before delivery, so take note of
the original setting. On AR30 / 40 pumps, set PRV to the first
wire – lever up / bypass mode)
• Turn on the Honda’s ignition.
• Set choke to ON. Note hot starts don’t need the choke.
• Set run speed to Minimum (see image)
• Pull Start, usually 2 times is sufficient.
o If not starting after 4 or 5 pulls, turn off the choke and
set the throttle to full power. Will usually start first time.
If all else fails, consult the Honda manual.
• Once the engine is running reliably at approximately ¼
power ….
o Confirm that the pump has primed and is working
(flow will be bypassing back to tank).
o Turn on the pressure valve, as circled.
For the AR30 it’s lever down.
o Adjust the pressure until you have the required
pressure, say 12 Bar as circled.
o Turn on the ball valve to the hose reel / spray gun
/ RetraSpray / boom, as circled.

GP-OMTRAY-A

SECTION 4A
PRE-OPERATION, MOTORISED MODELS
See section 4B for 12-Volt models.
• Spray. Hold down the hand grip lever of the spray gun.
Once the unit is spraying clean water, adjust the engine
power until the operating pressure (whilst spraying) is at
the required level. While the hand gun is spraying, check
that the:
o Nozzle spray pattern is even, adjusting the spray
pattern to suit the application you are planning to
carry out.
o Pump pressure is constant and within the limit of the
maximum pressure rating.
o Release the hand grip lever to stop spraying.
• For spot spraying applications, the required pressure
will vary significantly depending on the application and
equipment used (boom, lance, gun). Whilst checking the
sprayer with fresh water, also check for the maximum
pressure likely to be used / checking for leaks etc.
Boom Spraying
The AR30/40/70 sprayers fitted with one hose reel come
fitted with 2 taps on the pressure side – one to the spray reel
and the other is spare, for another hose reel or maybe a small
boom such as Croplands MBX-4, (note this is not a factory
fitted option).
Turn on the tap to the boom position. Water should now spray
from the nozzles. Adjust the spraying pressure to a maximum
of 5 bar pressure for boom spraying.
Whilst the pump is running, check all the nozzles to ensure the
spray pattern is uniform and check there are no leaks from
boom joints, fittings or the nozzle bodies.
For further information on boom spraying, see Section 6 -
Spraying Information.
SHUT DOWN
Note see section 5 for more information on cleaning &
flushing.
Spray to empty
• Always easier to shut down after spraying until the tank
and hose lines are empty.
• Reduce engine power to idle.
• Turn off the engine by using the ignition kill switch.
• Turn off the fuel if leaving for some time.
Shut down with tank partially full
• Reduce engine power to idle.
• Turn off the engine by using the ignition kill switch.
• Use the spray gun to relieve any residual pressure / liquid
in the spray line. Do not leave hoses full of water in the
heat of summer or the cold of winter.
• If the unit is not going to be used for spraying on the
same day, drain the tank and drain the hose.
With the initial start-up procedure is successfully completed,
the sprayer is ready for operation.
Go to section 5, Operation
CAUTION
!
When the tank becomes empty, the pump will
continue to run. Running the pump dry temporarily
will not cause damage. However, avoid letting
the pump run dry for long periods.
