Aim Command System
Rate controller
Uses pulse width
modulation through a pulsating electric solenoidPulse 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 evenSlide3
Advantages of Aim Command
Constant
p
roduct pump pressureOn the go rate change
Independently holds target
r
ate 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 Slide4
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
Slide5
Direct Chemical Injection Slide6
Advantages of Chemical Injection
Less
pesticide exposure
to applicatorAccurate 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 pesticidesSlide7
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
D
ecrease in chemical exposure
Decease in amount of cleanout timeSlide8
