  1. Aim Command System & Direct Chemical Injection By Kevin White

  2. 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

  3. 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

  4. 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

  5. Direct Chemical Injection

  6. 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

  7. 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

  8. 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
