Wheels & Tyres - Goldacres Prairie Compact 2000L MY19 Operator's Manual

Wheels & Tyres
All tyres used on Goldacres sprayers have been
designed to carry the maximum loaded weight of
the sprayer when travelling at 20 km/h. The load
capacity of the tyres decreases as travelling speed
increases so it is important to heed this travelling
speed limit.
The tyre pressure also needs to be checked regularly
(check every 8 to 12 hours of operation) and
maintained at the required tyre pressure.
There are many factors concerning the appropriate
tyre pressure for a particular tyre and load. For
example, the tyre size, rim type, tyre status (driven
or free rolling), load, speed, haul length and ply rating
all need to be considered when determining the tyre
pressure.
The rated pressure and capacity, shown in the chart
below, is applicable when the machine is stationary.
The cyclic loading pressure & km/hr is applicable for
machines that are loaded and moving.
DETERMINING CORRECT TYRE PRESSURE:
• Determine the maximum weight of the sprayer
when loaded (do not forget to add the weight of
the any other tanks on the sprayer when filled).
• Allow for each tyre to carry half the maximum
loaded weight of the sprayer (this does not allow
for any load on the tractor pull or cyclical loading,
which provides for a safety margin).
• Determine what tyre size and ply is on the
sprayer.
• Determine what appropriate tyre pressure
will provide the load capacity required by the
respective tyre as indicated in the following table.

TYRE SPECIFICATION
NOTE: If a tyre is replaced with a different brand
or size, please contact the supplier for correct air
pressures to suit the load carrying capacity of this
machine.
NOTE: PSI = Kpa x 0.145
EXAMPLE: 234 Kpa x 0.145 = 34 PSI
RECOMMENDED PRESSURE
