INITIAL PREPARATION AND SETUP Tractor Preparation and Hookup 1. Check and adjust tractor drawbar as shown so that it is located 16 to 22 inches above the ground. Then adjust the drawbar to a stationary position so that the hitch pin is directly below the center line of the PTO shaft.
Page 21
safety chain by crossing the chains under the tongue and secure to the draw bar cage or hitch or bumper frame. 4. Attach quick disconnect fittings to ends of hydraulic hoses to match tractor ports. Then con- nect hydraulic hoses to tractor ports in a sequence that is both familiar and comfortable to the operator.
Page 22
Some tractors use two 6-volt batteries as a power NOTE: source. Make sure there is a total of 12 volts delivered to the controller by connecting to the Positive (+) terminal of one battery and the Negative (-) terminal of the other battery. Reliable operation of the controller depends on a clean power supply.
Page 23
Make certain the red wire is connected to the positive IMPORTANT: side and the black wire to negative while attaching the power leads. Damage to the unit can occur if the leads are reversed. 8. Install the boom control switch box on top of the Raven Controller as shown in photo above.
Initial Preparation of the Sprayer 1. Lubricate the boom pivot points per the lubrication information in this manual prior to initial operation and at prescribed intervals thereafter. Also, make sure all tires have been properly inflated prior to each use. 2.
Page 25
5. If the tractor used to tow the sprayer is equipped with an open center hydraulic system, refer to the instructions on page C12 to install the correct valve cartridge in the hydraulic manifold under the sprayer tank. 6. Follow the directions in the sprayer control operating manual to calibrate and set the controller. 7.
Page 26
11. Turn on the master switch to direct water to the spray nozzles. At this point, the sprayer will be activated and spray tip performance can be visually checked. However, it is recommended that you also use a calibrated container and a stop watch to manually check and calibrate each spray nozzle prior to initial operation.
Controller Installation In most cases, the Field-Pro IV will come from the factory with a Raven 450 sprayer control pre-installed. However, the Field-Pro IV can also be ordered with the base deluxe plumbing plate and 5-valve stack assembly, which permits the owner to install any compatible control system desired.
Raven 450 Controller Figure 1. Overview The control valve used with the Raven 450 Control system is placed in an in-line location. In addition, the Raven control may be equipped with either a wheel drive or a radar speed sensor. Installation The Raven installation manual should provide most of the installation information required.
Open Center Hydraulic Modification Overview The hydraulic boom control manifold included with this sprayer comes equipped for use with closed center hydraulic systems. For the sprayer booms to operate with an open center hydraulic system the valve cartridge in the front of the manifold will need to be replaced. The following pages include instructions for removing the existing cartridge and replacing it with the correct car- tridge to operate with an open center hydraulic system.
Page 32
1. Locate the hydraulic valve manifold under the tank and behind the axle. 2. Remove the retaining nut from the end of the valve cartridge as shown at right. 3. Slide the purple ground wire and the two coils off the stem of the valve cartridge as shown in three pictures above.
Page 33
manufacturers number stamped at the end of the stem. The standard cartridge (RHS #69786) required for closed center systems is stamped with mfg #G0453 DA. The optional cartridge (RHS #69787) required for open center systems is stamped with mfg #G0459 EC. 6.
Main tank Quick-Fill, “off” position Rinse tank Quick-Fill, “off” position OPERATION Filling The Tank The main tank on the Field-Pro IV sprayer can be filled in one of two ways – through the top hatch using auxiliary equipment, or through the Quick-Fill valve auxiliary equipment. To fill the tank through the Quick-Fill valve: 1.
Sparge valve, “on” position Induction valve, “off” position Inductor Pump Inlet Inductor rinse valve, Selector Valve “on” position Inductor discharge valve, “on” position Adding and Mixing Chemicals Although chemicals can be added directly to the main tank through the hinged tank lid, the sprayer has been equipped with a chemical induction system for quick loading and thorough mix- ing.
6. Open inductor discharge valve to transfer chemical to main tank. 7. Rinse chemical container and inductor tank using handgun provided. Close inductor dis- charge valve when inductor tank is empty. 8. Close induction valve and raise inductor tank to transport position. Pull outward and upward on inductor handle to unlock scissors lift mounting bracket.

The two switches toward the left end of the control box control the folding and unfolding of the wings. Push the switches down to unfold the wings and push them up to fold the wings. To raise and lower individual wing tips, use the two switches to the right end of the control box. Push a switch up to raise a wing tip or push a switch down to lower a wing tip.
Extending Boom Wings. 1. Raise center lift to its maximum height. 2. Reposition stow lock brackets from boom “lock” position to “unlock” position. “Lock” position “Unlock” position 3. Raise boom wing tilt enough to clear boom stow racks. 4. Unfold wing fold cylinders. Make sure wing is completely unfolded with back pressure on center section and inner wing to eliminate sway while spraying.
6. Repeat steps 3-5 to unfold opposite wing. 7. Lower center section to desired spray height. During operation, each wing can be adjusted to a posi- NOTE: tion ranging from -5 degrees to +15 degrees from level in order to follow varying ground contours, such as terraces and waterways. Retracting Boom Wings To retract boom wings, follow the above steps in reverse.
Sprayer Operation Once you have filled the sprayer tank and thoroughly mixed the chemical(s), you are prepared to begin the spraying operation. At this point, you should have also determined the application rate and programmed that information into the rate controller computer, along with information on the spray tips, boom width, etc.

Foam Marker Operation Refer to the Operator’s Manual of your Foam Guidance System for operating instruction. 50 gallon foam solution tank Foam Guidance Pump Unit Controlling Drift Drift can be defined as the movement of spray droplets outside the intended target. It is one of the biggest environmental concerns chemical applicators face.
Although some products have a greater tendency to drift than others, due to their volatility, the potential for drift exists with any chemical. Unfortunately, with the advent of genetically altered crops like Roundup Ready soybeans, and Liberty Link corn, the potential damage that can occur as a result of chemical drift is greater than ever before.
• Boom height - Boom height is an important factor in controlling drift. A boom that is set too high obviously favors drift, since droplets have farther to fall, thus having more time and opportunity to drift off course. Doubling the boom height, in effect, doubles the length of time required for droplets to reach the target canopy.
• Nozzles which produce fine droplets are usually recommended for post-emergence applications, which require excellent coverage on leaf surfaces. • The most common nozzles used in agriculture are those which produce medium sized droplets. These can be used for contact and systemic herbicide, preemergence surface applied herbicide, insecticides and fungicides.
Rinsing The Sprayer It's important that you rinse the sprayer after each use, and every time you change chemical solutions in the tank. In most cases, it's best to rinse and flush the sprayer in the field, to mini- mize handling issues, with rinse water. In some cases, you may also want to add a commercial tank cleaner to the rinse water to help dissolve or neutralize certain chemicals.
Taking the time to clean the sprayer after each use is the most important thing you can do to improve the performance and longevity of your BESTWAY Field-Pro IV sprayer. This is particularly important after the use of suspension type chemicals, which can crystallize and plug the flowmeter, lines and/or spray tips.
Lubrication Grease Fittings Proper lubrication will help insure efficient operation of your BESTWAY sprayer and prolong the life of friction producing parts. Those parts equipped with grease fittings should be lubricated at the frequency indicated with an SAE multi-purpose type grease. Be sure to clean the fitting thor- oughly before using any grease gun.
Bestway dealer or RHS, Inc. Sprayer Nozzle Maintenance Spray Tip Care Careful cleaning of clogged spray tips can mean the difference between a clean field and one with weed streaks.
If a tip is clogged and does need clean- ing, only use a soft bristled brush or toothpick to clean it. Never use a metal object or wire brush. Use extreme care with soft tip materials such as plastic. Even a wooden toothpick can distort the orifice.
• Ceramic - Superior wear life and is highly resistant to abrasive and corrosive chemicals. • Hardened stainless steel - Very good wear life, good durability and chemical resistance. • Stainless steel - Good wear live, excellent chemical resistance and a durable orifice. •...
Outer Section Adjustment The outer wing section of both spray booms includes a pressure relief valve plumbed into the wing fold cylinders. In the event this section of the wing contacts an immovable object, the spring loaded valve will allow hydraulic oil to bypass the cylinder, permitting the wing tip to breakaway and fold rearward.
Tire Pressure Tire pressure should be checked prior to each use of the sprayer and maintained as follows: LOADED TIRE PRESSURE STARTING PRESSURE FOOTPRINT LENGTH 380/90 X 46 Radial Tires 26 PSI 31” 18.4 X 46 Radial Tires 20 PSI 31”...
11. Fill hub cap half full of wheel bearing grease and install on hub. 12. Install wheel, tighten lug nuts to 265 foot pounds and remove jack and blocks. Tread Width Adjustment Clamping Plate Axle stop Vertical Adjustment Bolts Make axle adjustments only when tank is empty and the DANGER: sprayer is attached to an adequate towing vehicle that is in park.
2. Loosen the (6) 3/4" x 3" mounting bolts that clamp the clamping plates to the axle. 3. Loosen the (2) 3/4" x 3-1/2" vertical adjustment bolts on the underside of the axle tube. Do not remove the clamping plate that secures the axle NOTE: stub in position.

8. Pour 10 to 15 gallons of non-toxic recreational vehicle (RV) antifreeze into the main tank and rinse tank. Operate the sprayer until all hoses have been filled and RV antifreeze has begun to spray out each of the spray nozzles before shutting off. Then make sure no RV antifreeze is leaking from any fittings, hoses or nozzles.
