  1. Application of Sprayer Technologies in Field Equipment Dustin Simmons BAE 4213 April 23, 2001

  2. Objectives • To introduce you to some of the new sprayers on the market and the technology they utilize related to precision agriculture. • To give you a look at some research relating to sprayers.

  3. John Deere 4710 & 6700

  4. J. D. Parallel Tracking • Pinpoints the sprayers location to an average accuracy that’s within 10 inches. • Uses a monitor and audible beeps to guide you across fields • Allows you to spray at night or when visibility is limited.

  5. J.D. SprayStar • Allows the operator to set and choose from three programmable rates on-the-go. • Pre-set rates can range from 4 to 94 gpm. • Allows you to vary agitation rates from the cab. • System records area, volume, and time spent spraying. • Stores up to six job summaries.

  6. John Deere SprayStar

  7. J.D. Suspension System • Independent strut system with adjustable air springs at each wheel based on the F-18 fighter jet suspension.

  8. J.D. Boom Suspension • Three separate systems keep the nozzles an equal distance from the crop resulting in uniform spray coverage. • An accumulator cushions the boom vertically. • Center pivot roll system allows the boom to follow the same altitude of the machine on hillsides and terraces. • Yaw suspension resists boom flap.

  9. John Deere • “Since the average annual use for sprayers is approximately 600 hours per year, that 2 mph difference could increase your earnings by $28,800.

  10. Case 3200B

  11. Case AIM system • Ag Information Manager (AIM) Utilizes a Pentium 133 processor with Windows 95 operating system. • Guidance module provides sub-meter accuracy when used with DGPS. • Multiple sets of guidelines can be established within a field to accommodate for irregular boundaries.

  12. Case AIM system cont’ • Navigation System will direct the operator over a set of selected parallel swath lines using a light bar. • Uses pulse width modulation to manage droplet size. • Nozzle pulses are timed to alternate along a boom providing abundant opportunity for spray from individual nozzles to blend for consistent deposition on the target.

  13. Case ARM System • Application Rate Management (ARM) combines swath guidance and multiple product variable rate application

  14. Case ARM System cont’ • Communicates with GPS ready rate controllers and automatically adjusts the rate of application. • “Auto Spray” feature reduces over spray. • An agrochemical prescription map can be created using a compatible GIS package.
