Spraying FAQ

Q: Do I need different nozzles for different chemicals?
A: Yes, there is basically 4 types of chemicals: Herbicides, fungicides, insecticides, fertilizers. Most pre-plant (herbicides) and fertilizers apply with lower pressure and larger droplet sizes. Always check your chemical label for proper droplet size and chemical pressure

Q: Why is there different nozzle spacing for booms? 
A: 20" is most common spacing that fits many tips and provides good coverage, 15" is used for applying higher rates of fertilizer and to split 30” crop rows with drop nozzles, 10" is not common mostly used for very high rates.

Q: My Raven Viper Pro won’t log or paint application trail when starting an existing job. What can I do?
 A: When starting an existing job, the Raven Viper automatically pauses the job, in order to log data or paint an application trail; the user will have to press “MENU” and the “CONT JOB” to continue to log data or paint.

Q: I purchased a Raven SCS-Sidekick for my precision farming operation. Can I hook this up to a non-Raven console? A: When connecting an SCS-Sidekick to a non-Raven console an adapter cable is available which will enable the Raven Sidekick console to tie into any boom sense cable, in a non-Raven control system. To allow for a measure rate per acre, a speed input signal is also required. The speed signal can come from any standard Raven radar or Raven simulated radar GPS system or may be adapted from non-Raven speed sources.

Q: When is moisture testing with a Dickey-john moister tester most important? A: Harvest – Moisture testing provides the knowledge to make informed decisions. Using a Dickey-john moisture tester onsite can facilitate the prioritization of where to harvest. An error of 1% moisture in a 100 acre field amounts to $2,000. Know when to move equipment, and plan harvesting by location and moisture. If you spend half of the day moving equipment to the wrong field it can easily cost $300 to $400 in fuel and man hours alone.

Storage – Understanding storage considerations can maximize the overall investment. Decisions can be made regarding when to blend grain based on moisture levels thus mitigating a wet, harvest product.

At the Time of Sale – Everyone wants to maximize profits and time management should not be forgotten when considering profit returns.

Q: How do I choose the right Dickey-john moisture tester for my application? A: For a versatile, portable tester, choose the Dickey-john mini GAC PLUS. No other handheld moisture tester offers test weight. Simply said, no other handheld moisture tester on the market is more accurate than the mini GAC PLUS. Dickey-john took great pains to port the technology from the industry-standard GAC2100 into a handheld. Drawing from the same library of calibrations, it is a superior value. For a mobile operation, the Dickey-john GAC500XT is a good choice. The semi-automatic tester provides moisture and test weight and operates off 12 VDC or from AC power. Performance is comparable to the federal-standard GAC2100b. For a fully-automatic non-portable tester choose the GAC 2100. The Dickey-john GAC Series moisture testers have temperature compensation that is vital to accurate moisture.

Q: Do you sell fertilizer equipment for home use or just farm and commercial agriculture use? A: Unless you have a very large 10 acre plus yard, we mainly only retail three ton or larger fertilizer spreaders, suitable for large farming operations and commercial agriculture businesses.

Q: Do you sell all models of Hypro pumps? A: Yes, we offer a full line of Hypro pumps including centrifugal pumps, transfer pumps, roller pumps, diaphragm pumps, and piston pumps.

Q. Can my fertilizer equipment be used for spreading lime? A: This is a very good question, and in most cases the answer would be no. However, there are a few cases in which your fertilizer equipment can be used for spreading lime. If your fertilizer spreader has a 16” or larger bed chain, and twin motor drive on the conveyor on hydraulic models, it will spread lime. If it is a press wheel drive and has dual drive chains, or a 60 heavy chain with a 16” or larger bed chain, it will spread lime.

Q: Can the TeeJet Matrix Guidance System be used with any model of agricultural spray equipment? A: Yes, the TeeJet Matrix system is a simple guidance product that will run as a stand-alone guidance product, or it will operate TeeJet’s Boom Pilot, which is an automatic boom shut-off or Field Pilot, which is Teejet’s version of auto steer.

Q: Are the Shurflo pumps that you retail the same as the Shurflo pumps that fit in my camper? A: Shurflo Pumps, especially the Classic 2088, are the world’s most popular RV pumps. The classic Shurflo pumps have been serving the needs of motor home and RV owners for many years. Three independent pumping chambers give you three-way dependability. Classic Shurflo pumps are designed for multiple-fixture intermittent duty applications and include such features as: quiet performance, self priming, running dry without damage, and a built-in check valve. 

Q: What factors should I consider when selecting sprayer tips?
 A: The most important thing you need to do is read the pesticide label and note the manufacturer’s instructions. Select sprayer tips that meet the recommendations for:

  • Spraying technique – banding or broadcast
  • Sprayer speed
  • Application rate
  • Flow rate
  • Spray pattern
  • Tip size and pressure
  • Spray quality

Q: How do I know my flow meter is accurate?
Make sure the flow meter calibration number (tag on flow meter) matches the flow meter calibration number in rate controller.If yes, then follow the re-calibration procedure for your flow meter.

Q:How does a rate controller work?
A rate controller needs all correct constants: boom width, speed, programmed rate (GPA). The controller then looks at output (from flow meter) and either increases or decreases the control valve to match boom width, speed, and rate.

Q: Should I spray during extreme hot or drought conditions?
Many products require weeds to be actively growing and not under heat stress for the chemical to work and all labels contain vital information on what measures must be put in place to ensure adverse outcomes do not occur.

Q: How do I manage weed resistance build up?
Resistance of diseases, pests and weeds to agricultural chemicals is a naturally occurring phenomenon that can be made worse by poor chemical use practices, so is essential for farmers to manage. Some groups of products and target weeds, pests and diseases are particularly susceptible to resistance build up and the only way to prevent it is to adequately manage rotations of different chemicals from different activity groups (for fungicides) or Modes of Action (for herbicides and insecticides).

Q: My Raven console is not showing a rate? How do I check my flow meter for operation?
A: Click Here for Flow Meter Testing Procedure

Q: How do I read a nozzle chart?
A: The nozzle charts are set out as follows: read the sprayer speed to be used, and follow the column down to the desired application rate in gallons per acre. Then follow this row to the left, and you will find the required spraying pressure and the nozzle to be used.
