Aim Command System &

Direct Chemical Injection

ByKevin White

Aim Command System

• Rate controller• Uses pulse width modulation

through a pulsating electric solenoid

• Pulse cycles are controlled by ground speed and the master rate controller.

• A) Low flow rate =Solenoid cycles off for longer periods of time

• B) High Flow rate = Cycles on for longer periods

• C) Medium Rate = Cycles are even

Advantages of Aim Command

• Constant product pump pressure

• On the go rate change

• Independently holds target rate constant compared to the ground speed.

• Target rate can be achieved while boom pressures are changed.

• Increases Drift Control• Can lower pressure to

produce larger droplet size without changing gal/acre

• Chemical Savings • Accurate flow and direct

placement

Disadvantage of Aim Command• Cost is the major disadvantage

• For 100 foot boom, the option was $27,000

• Maximum of 20 gallons/acre• Anything over 20 the

conventional rate controller must be used

• Maintenance • Cleaning of filter/screens

foreign particles can not interfere with the pulsating

• Solenoid replacement $100 to $145 to replace

• Electric Wires on every nozzle body

Direct Chemical Injection

Advantages of Chemical Injection• Less pesticide exposure to applicator

• Accurate measuring and mixing of pesticides

• Eliminates having excess chemicals in carrier tank after finishing a field

• Allows for fast and easy clean out

• Can switch to multiple chemicals without having to clean sprayer which causes down time. Also decreases cross contamination

• Ability to have VRT technology while applying pesticides

Cost of Direct Injections

• Single 24 gallon tank with Raven Sidekick

• $5,900• Advanced systems with

multiple tanks and pesticides can get costly

• Return on investment could be achieved within a half a year depending on the amount of acres sprayed

• This is due to the amount of savings of chemicals

• Decrease in chemical exposure

• Decease in amount of cleanout time

The Importance of Direct Injection & Aim Command During Variable Rate Application

• Accurate on the go carrier flow rate change

• On the go pesticide concentration rate adjustment

• Precise mixing

• Direct placement of chemical
