SPRAYING INTRODUCTION
This section is intended to offer practical guidelines for the distribution of liquid chemicals over an area of turf
grass such as golf courses, park land, school grounds and lawns. SMITHCO makes no representation as to the
suitability of any technique or product for any particular situation. This section is suitable for self-propelled spray
vehicles or sprayers mounted onto vehicles.
Boom Spraying is the most effective, accurate and efficient method of applying chemicals to large turf areas. It
may be done by means of:
• A dedicated spray vehicle
• A sprayer mounted upon a utility vehicle
Sprayers are typically equipped with wide spray booms. Generally these booms are between 15 feet (4.5 m) and
20 feet (6 m) in width. They are divided into three sections, with hinges that permit the long outer sections to
automatically move out of the way and reset if an obstacle such as a tree or fence is in you path.
To minimize the chance for missed areas or double application use a device to mark the outside boundaries of
each spray swath. Foam markers and dye markers are advisable.
PROCEDURE TO RE-CALIBRATE FLOWMETER
1
. Enter a Meter Cal number of 10 in Meter Cal Button
2. Enter a Total Volume of Calibrating the Pressure Gauge in Total Volume button
3. Switch Off all booms.
4. Remove a boom hose and place in calibrated 5 gallon container
5. Switch on appropriate boom switch and master switch. Pump exactly 10 gallons.
6. Readout in Total Volume is the new Meter Cal Number. Should be within 3% of number stamped on
flowmeter.
7. Repeat the procedure several times to ensure accuracy.
8. To verify calibration, fill applicator tank with predetermined amount of measured liquid. DO NOT RELAY
ON GRADUATION NUMBERS ON MOLDED TANK. Empty tank under normal operation conditions. If the
number under total volume is different from the predetermined amount of measure by more than 3%
compete calculation in back of book.
9. Enter corrected Meter Cal before resuming application.
