INTRODUCTION
C-Dax thanks you for your purchase of an advanced spreader from C-Dax Ltd. C-Dax Ltd is committed to
providing you, the farmer, with quality applicating systems.
DESCRIPTION
The C-Dax C-DIT300 is a ground-driven spreader designed for application of pelleted fertilisers. It can also be
used for application of other products such as grass seed and magnesium oxide. The uniquely designed 300-
litre translucent non-corrosive polyethylene hopper is specially profiled for good product flow and ease of
filling. The convenient flexible polypropylene cover is easy to remove, install and store if not required. A high-
quality stainless steel agitator and shutter ensures even flow of product to the spinner. A unique spinner
design ensures wide, even spread of product over 180 degrees (Urea). The drive train uses high quality steel
and a double sealed self-aligning bearing and heavy-duty gearbox for maximum durability. While seated, the
operator has access to the control handle. This handle allows disengagement and engagement of the clutch
and setting of product feed rate all in one motion. Also standard are mudguards, swivel tow-hitch and a fully
shrouded polyethylene front deflector to further protect the operator from product being thrown off the spinner.

it is fair and reasonable that the provisions of the Consumer Guarantees Act 1993 (NZ) do not
apply to those transactions to the fullest extent permitted by law.
OPERATION
The product to be spread is placed in the hopper. When the spreader is towed forward, the right hand wheel
drives through the lever operated mechanical clutch and gearbox to turn the spinner in a clockwise direction.
When the control handle is in the disengage position (fully back) the clutch is disengaged and the shutter is
closed. Pulling the handle forward (towards the operator) engages the clutch and rotates the shutter located at
the bottom of the hopper to an open position. The size of the opening is set by a shutter stop lever, which
locates into one of nine pre-set positions.
An extension of the spinner boss is connected to a stainless steel agitator arm inside the bottom of the hopper.
The agitator ensures that product flows continuously out of the hopper to the spinning disk.
A delivery chute on the bottom of the hopper ensures that product is delivered to the correct spot of the disk so
that the deflectors distribute the product over a wide angle behind and to each side of the spreader.
The clutch systemcan be engaged or disengaged at up to 5KPH while the spreader is in motion.
A fabric hopper cover with an elastic band sewn into the outer edge to grip the lip of the hopper can be fitted to
prevent rain and debris from entering the hopper.
WARNING
To prevent premature failure or damage to the CDIT300 clutch system, do not engage or disengage the clutch
at speeds in excess of 5 KPH.

8
CALIBRATION
1. Ensure the control handle is fully back (clutch disengaged, shutter closed).
2. To calibrate your spreader, place a measured amount of product (10 Kg) in the hopper.
3. Set the Shutter Stop Lever to the position (1-9) indicated in the Calibration Guides below. Hole position 9
(shutter fully open) is denoted by two holes vertically one above the other.
4. Tow the spreader at the desired speed and pull the control handle forward to engage the clutch and open
the shutter.
5. When the product has been exhausted, measure the distance covered and band width in metres. It is
recommended that this be done over an area where the product can be seen on the ground so that the
spread width can be measured.
6. Check the application rate using the following formula:
Rate (Kg/ha) = product applied (Kg) x 10,000
distance travelled (metres) x spread width (metres).
7. Adjust either the Shutter Stop Lever or the speed of travel until the desired application rate is achieved.
NOTE
Because of variations in product characteristics, speedometer calibration and driving speed, the information in
the calibration guide should be regarded as a starting point only. It is recommended that the spreader be
calibrated before use.

Magnesium Oxide
Magnesium Oxide powder is applied at a rate determined by the number of cows to be treated. When
spreading this product, calculate the weight of powder to be applied and apply this amount using shutter
setting 4 or 5. Because this product may set hard if left exposed to air, it must not be stored in the machine
even for a short time. Load the spreader only with the amount required to be spread and clean all traces of
product from the machine after use.

9
OPERATING THE SPREADER
When the spreader has been correctly calibrated, the hopper may be filled to the required level and spreading
commenced.
To reduce agitator damage to product and to ensure that product is not forced past the agitator shaft when
towing the spreader to the area to be treated, the drive to the gearbox should be disconnected by ensuring the
control lever is in the disengage position (fully back).
WARNING
To prevent damage to the spreader do not tow the spreader at speeds in excess of 15 Kph.
To prevent damage to the mechanical clutch do not engage or disengage the clutch on the CDIT300 at
speeds in excess of 5 KPH.
CAUTION
The double roll pins present in the clutch assembly are designed to shear if subject to excessive use
(preventing greater damage to the rest of the unit). If you find these pins to continually break, engage the
clutch at a slower speed.
To prevent inadvertent operation of the shutter while the spreader is in transit it is recommended that the
Shutter Stop Lever be moved to Position 1 to lock the shutter closed.
To prevent the shutter from vibrating closed when the spreader is operated over rough ground, the Shutter
Control Handle friction may be increased by tightening the adjustment nut at the bottomof the Handle.
Adjusting the Spread Pattern
The spreader has been set up for spreading pelletised fertiliser. When spreading lighter products or products
with a high powder content it may be necessary to adjust the deflectors on the spinner to centralise the spread
pattern. To shift the pattern to the left (facing forward) the inside end of the vanes should be moved anti-
clockwise. To shift the pattern to the right (facing forward) the inside end of the vanes should be adjusted
clockwise. These positions are highlighted in the diagram on the following page.
Shift to the left setup
Default setup
Shift to the right setup
WARNING
To prevent damage to the spinner and shrouds, do not operate the spreader unless the screws are tight.
Fitting the Rain Cover
To fit the rain cover to the hopper, loop one corner of the cover over a corner of the hopper then stretch the
cover over the opposite corner of the hopper so that the elastic edge holds it in place. Then stretch the third
corner over the hopper rim followed by the last corner. Ensure that the cover is properly stretched over the
hopper rim before moving off.

10
MAINTENANCE
The following maintenance actions are mandatory for reliable use of the spreader.
Before Use
Check the tyre pressures and charge with air as required. The correct pressure is 12 psi. (80 Kpa)
Disengage the clutch by ensuring the control lever is fully back then turn the spinner by hand to ensure that it
is free to turn without interference.
Check the hopper to ensure that no debris is inside.
If the spreader has not been used for some time, grease the wheel bearing located in the pillow block mount
near the drive wheel.
Check the gearbox for leaks. If leaks are detected it will be necessary to drain and replenish the gearbox with
400ml of SAE 30 oil.
CAUTION
To replenish the gearbox the spreader may be inverted to place the filler plug uppermost. However in doing so
extreme care must be taken to prevent damage to the spinner and deflectors.
After Each Use or Daily when in Use
Remove all traces of product from the spreader by brushing or washing. Pay particular attention to areas
where product has accumulated and built up. Remove by scraping if necessary taking care not to damage the
surface finish of the spreader or its components.
If washing do not direct high-pressure water onto the gearbox, axle or wheel bearing seals.
After washing, apply grease to the grease nipple on the wheel bearing and apply water displacing fluid such as
WD 40 or LPS3 to all metal parts.
Check for damaged or worn components and replace as required.
NOTE
To ensure trouble free operation of the mechanical clutch, pay particular attention to
cleaning and removal of any product build-up on the unit.
HINTS
The clutch mechanism in the axle assembly utilises a stainless steel shaft and with self-lubricating plastic
bushes on the moving part of the clutch. This arrangement does not require greasing and doing so may attract
unwanted particulate into the mechanism.
If the drive axle is removed from the axle housing for any reason care must be taken to ensure that both the
axle scroll and bush are clean and free of debris before reassembly.
To remove the agitator from the hopper, remove the bolt, which attaches the agitator shaft to the spinner
flange assembly then withdraw the agitator from inside the hopper.
When ordering replacement parts always quote the Part Number of the required part.
The mechanical clutch engage/disengage bolt, which operates the clutch head is intended as a replacement
item. If excessive wear is noticed, remove the bolt and replace with part number # 2890-0816.
