B.0. SYSTEM OVERVIEW
Mid-Tech has drawn upon many years of experience in electronically controlled chemical application to design and
build this spraying system. We rely on the experiences of our users as well as ourselves to help us continually improve
our systems. Please contact us to let us know what you like or don’t like about the TASC. We appreciate your com-
ments, and THANK YOU for purchasing a MIDWEST TECHNOLOGIES Total Application Sprayer Control (TASC).
B.1. THE TASC SYSTEM CONTROLS BOTH CARRIER FLOW AND CHEMICAL INJECTION RATES
TASC is available in three different models, depending on the operator’s requirements. These models are the: TASC-
6000, TASC-6300, or TASC-6600.

TASC-6000 is a basic sprayer flow control system. TASC-6000 performs both monitoring and control functions,
freeing the operator from the requirement to maintain a constant vehicle speed and a constant sprayer pressure. TASC-
6000 assures a constant and precise application rate for the material from the main tank. Because of its modular design,
a TASC-6000 can be upgraded to either a TASC-6300 or a TASC-6600.
TASC-6300 or 6600 are chemical injection controls as well as sprayer flow controls. These two units automatically
introduce and mix active chemicals into the main carrier flow during spraying operations. The TASC-6300 and 6600 are
simple, easy to use, and virtually automatic. TASC-6300 can simultaneously control up to three separate chemical
injection pumps, while TASC-6600 can control up to six injection pumps.
Chemicals are not mixed in the main tank when using either TASC-6300 or TASC-6600. The operator uses chemical
only where it’s needed and at just the rate necessary to do the job. The operator finds he is doing a more precise job of
application, with less wasted chemical, and minimum exposure to dangerous or toxic materials.
B.1.1. HOW A TASC-6000, 6300 or 6600 CONTROLS CARRIER APPLICATION RATE
TASC senses ground speed, active boom width, and carrier flow rate. When a change in ground speed or boom width is
detected, TASC changes the carrier flow rate to maintain a constant, pre-selected rate per area. An increase in ground
speed results in a proportional increase in flow rate. A decrease in ground speed results in a proportional decrease in
flow rate. Comparisons of flow rate, active boom width, and ground speed are made approximately four times each
second and corrections are made to the flow rate as soon as an imbalance is seen.
