This hopper is normally stowed at the rear of the machine alongside the spray pump
and is of the Venturi type.
The booms should be lifted to enable the hopper to swing out and down to the
working position.
Select Venturi position on the rotary 'pressure' tap. Select wash down ring on front left
hand side of hopper, add chemical. Suction is controlled by a 2-way tap mounted at
the bottom end of the hopper. The two-way tap should be closed after each induction
process. Failure to close this tap will cause severe frothing within the spray tank as air
is inducted through the Venturi.
To wash out chemical containers, select can wash position with 3-way tap on left-
hand side of hopper. Wash out containers. Please ensure correct disposal of
containers.
CHEMICAL INDUCTION HOPPER
As standard on a 24m sprayer a hydraulically driven 300L/min 5 cylinder
Immovilli pump is fitted. Providing the engine revs are at 1000 rpm or above, the
spray pump will turn at approximately 540 rpm. This speed is automatically
maintained irrespective of engine speed above 1000 rpm.
An optional ‘dual speed’ Immovilli 400L/min pump is available for applying
higher rates on the 24m booms and is standard on all booms over this width.
Speed 1 gives an output of 275L/min (375 RPM). Speed 2 gives the full output
from the pump.
The majority of conventional spraying may be carried out at the slower pump
speed with a corresponding increase in pump life.
When ‘self-filling’ there will be little increase in the fill speed on speed 2
compared to speed 1 due to limitations of the fittings and suction hose lengths.
SPRAY PUMP
This extra fine mesh filter is fitted directly before the boom manifold and is
particularly useful for low volume work where crystallising chemical
presents a problem.
Two elements are supplied - blue 50 mesh for conventional 200L/ha
outputs. A finer red 80-mesh element for low volume work. The element
may be removed for high output rates.
The tap fitted to the strainer bowl is used for flushing the filter clean. It
should be used at least daily and before every change of chemical.
Please dispose of the flushing’s in an environmentally friendly manner

If a two speed spray pump is fitted, either speed will operate the Venturi but the fast speed will give the greater
performance.
Ensure suction tap is fully closed and rotary 'pressure' tap is in spray position after use.
