Dear Owner,

Thank you for purchasing a HARDI

product and welcome to the ever

increasing family of HARDI

sprayer owners.

Our sprayers and accessories are rapidly becoming a familiar sight on North American farms. We believe that this results from growers becoming increasingly conscious of chemical input costs and the vital need for cost effective chemical application equipment.

Please take the time to thoroughly read the Operator’s Manual before using your equipment. You will find many helpful hints as well as important safety and operation information.

Some of the features on your EAGLE 3PT boom were suggested by growers. There is no substitute for “on farm” experience and we invite your comments and suggestions.

Please address your correspondence to the Service Manager at one of these branches:

Sincerely,

Tom L. Kinzenbaw President

1.0 INTRODUCTION

The EAGLE 3-point boom is a fully suspended hydraulically operated spray boom featuring self-stabilizing trapeze suspension with coil springs and a shock absorber to control the rate of boom movement.

The 3-point hitch frame meets the requirements for mounting the sprayer to a CAT II or CAT III 3 point hitch or CAT II or CAT III-N quick hitch coupler. The Hitch frame has a pump mounting plate (for PTO and hydraulic drive pumps) as well as provision for mounting control units and other accessories.

The 48’ and 60’ EAGLE 3-point boom also has parking stands attached to the center frame which allows the boom to freestand when not in use.

Three versions of the EAGLE 3-point boom are available. The “HY” features simultaneous boom wing folding. The “HT” features simultaneous wing fold and individual wing tilt through three tractor double acting outlets. The “HZ” features electric hydraulic wing fold (same as “HY”) plus individual wing tilt. This will require two tractor double acting outlets and a 12v power supply. The hydraulic hoses that attach to the tractor are fitted with 1/2” NPT quick couplers.

The EAGLE 3-point boom can be equipped with either single Snap-fit or triplet nozzle bodies. Two pump and control systems are available as options to the 3-point EAGLE boom. The Diaphragm pump system features a HARDI

361 Diaphragm pump and electric control unit with HARDI-matic, a mechanical rate controller, and a self-cleaning pressure filter. The Centrifugal pump system features a Ace 206 hydraulically driven pump with an electric control unit. Both systems are complete with adjustable agitation, constant pressure feature, incab control box, system pressure gauge, and PTO shafts.

3. Activate switch (A)(Fig. 11) upwards and hold to unfold left hand boom (Holding the switch in the down position will fold the boom). To unfold right hand boom, activate switch (B)(Fig. 11).

4. "One side folding" will be achieved by following the above procedure except that only one of the switches is activated.

26 HARDI® EAGLE 3PT BOOM OPERATORS MANUAL

5.4 Folding One Side Only (HZ Hydraulics Only)

If only one side of the boom is to be used for spraying , first unfold the boom completely and then turn switches off, then flip the switch for the side that is to be folded and activate the double acting outlet to fold that side into transport position.

Note: It is not advisable to go directly from transport position to

spray position with one side only. Both wings must first be completely unfolded.

The following tables show what types of spray nozzles are suitable for different applications. It is important to use the correct nozzle.

5.5 Nozzle Selection

Correct selection of nozzle and calibration of the sprayer are critical to achieve accurate and cost effective use of farm crop protection products.

Your HARDI sprayer has been supplied with 110° flat spray Green Color Tips™ that will apply approximately 20 U.S. GPA at 30 PSI and 5 MPH. The 110° flat spray nozzle was chosen rather than the 80 degree nozzle for two reasons: 1- It may be used at a lower minimum height which reduces the risk of wind drift; 2- it's greater overlap permits better uniformity of spray distribution, particularly if boom height varies on rough ground. Normal boom height setting with 110° nozzles is 18" to 20" above the crop or weeds, whichever is taller. Should you wish a different application rate or different type of nozzle, HARDI manufactures a nozzle for virtually every need.

IMPORTANT:

Always consult your chemical supplier for recommended chemical rate and water application rate. Always wear protective gloves when handling nozzles.

5.6 Calibration

WARNING:

ALWAYS CALIBRATE YOUR SPRAYER WITH CLEAN WATER ONLY! IN ADDITION, WEAR PROTECTIVE CLOTHING WHEN CALIBRATING YOUR SPRAYER!

Why must you calibrate a sprayer?

A nozzle selection chart will tell you what application rate you should expect. Variations due to nozzle wear, errors in pressure adjustment, and tractor speedometer can result in a possible error in application rate.

How do you calibrate a sprayer?

Calibration kits are available from HARDI, #818103 for US gallons & #818104 for metric calibration. Following are some tips to remember when using the calibration kit method:

• When determining the length of time required to drive the recommended distance, drive in actual field conditions with a half-full tank.

• Repeat the test several times, each time avoiding the tracks from the previous test. Take the average of the times recorded.

• Calibration of the sprayer should be completed at the beginning of the season and repeated after every 2 to 3 full days of spraying, and every time you change volume rate or use new nozzles.

• Before you calibrate, check the flow of each nozzle. If it puts out more than 10% of its original volume, replace it.

Select your calibration method- Ounce method or Formula method. Then follow the steps described on the following pages:

30 HARDI® EAGLE 3PT BOOM OPERATORS MANUAL

Ounce Method

1. Determine how long it takes you to cover the test strip. Use the following chart to determine the length of your test strip. Row width for broadcast application is equal to your nozzle spacing. For your drop nozzle or band application, use row spacing.

Row width or nozzle spacing (in.) Distance (ft.)

40 102 38 107 36 113 34 120 32 127 30 136 28 146 26 157 24 170 22 185 20 204 18 227 16 255

14 291

2. Measure the amount of time it takes you to travel the test strip when

throttle is set at spraying speed.

3. In a container (with oz. measurements), catch the spray from on

nozzle for that amount of time. For drop or band nozzles, catch the spray from all nozzles for the row.

4. Read the ounces in the container. That is the actual U.S. GPA applied.

(ounces - GPA)

31HARDI® EAGLE 3PT BOOM OPERATORS MANUAL

Formula Method

1. Check your spraying speed. Measure a test strip of at least 200 feet (300 feet is ideal). Travel the distance at the speed you plan on spraying and record the time it takes to travel the distance. Read from the chart or use the formula to find your exact travel speed.

Speed in MPH Travel Time (in seconds)

200 ft. 300 ft.

3.0 45 68

3.5 39 58

4.0 34 51 Formula: 4.5 30 45 distance (ft.) x 0.68

7.0 19 29

7.5 18 27

8.0 17 26

9.0 15 23

2. Calculate the required nozzle output. Use either the nozzle wheel (if

nozzle spacing is 20 inches), or this formula:

Formula: Formula:

GPM =

GPA x MPH x W (in.)

GPM =

10 x 7 x 20

= .24 GPM

5940

Note: W= • Nozzle spacing (in inches) for broadcast application.

• Row spacing (in inches) divided by number of nozzles per row for drop nozzle application.

• Sprayed band width or swath width (in inches) for band application divided by number of nozzles per band.

• Note that on the nozzle wheel, W = 20 inches.

3. Set correct pressure. Read the required pressure from the nozzle table in the nozzle catalogue or nozzle wheel. With clean water in the tank and line, turn on the sprayer and set the target pressure. Collect the spray from one nozzle for one minute in a container. Adjust pressure until you collect the precise GPM called for.

32 HARDI® EAGLE 3PT BOOM OPERATORS MANUAL

Calibration for carriers other than water

Use the following water rate conversion chart to determine the right conversion factor. When you've determined the new converted GPM or GPA, you can follow the steps on either the pressure or ounce method of calibration.

6.0 ADJUSTMENTS

WARNING:

• HARDI CANNOT ASSUME RESPONSIBILITY OR BE HELD LIABLE FOR ANY LOSS OR DAMAGE THAT OCCURS DUE TO LACK OF ADJUSTMENTS OR MAINTENANCE.

• WE URGE YOU TO FOLLOW THE ADJUSTMENT AND MAINTENANCE RECOMMENDATIONS FOR EVERYONE’S SAFETY.

• MAKE IT A DAILY HABIT TO INSPECT YOUR BOOM FOR NEED OF ADJUSTMENT OR MAINTENANCE.

• IMMEDIATELY REPLACE ANY PARTS ON THE BOOM THAT ARE WORN OR BROKEN.

• ALWAYS CLEAN YOUR BOOM BEFORE ADJUSTING IT TO AVOID UNNECESSARY CONTACT WITH CHEMICALS.

The boom wing sections on the Eagle 3 point boom have been preassembled, adjusted and tested in the factory. The boom however, will require additional adjustments shortly after being taken into service (10 hours) and thereafter on a minimum annual basis to perform at its maximum levels.

To further insure the booms proper performance, the Eagle 3 point boom also has to be maintained on a regular basis.

PLEASE FOLLOW THE SUGGESTED MAINTENANCE INTERVALS.

Perform the adjustment procedures in the same sequence as they are written in this manual.

6.1 Adjustment And Maintenance Intervals

IMPORTANT:

To maximize boom life and performance, retighten all

boom fasteners and inspect boom for proper adjustment after the first 10 hours of use. Thereafter adjust the boom at a minimum of once a year and check all fasteners at 50 hr. intervals. Lubrication of the boom should be done daily to ensure maximum performance and life.

34 HARDI® EAGLE 3PT BOOM OPERATORS MANUAL

6.2 Checking And Adjusting Sprocket Timing

1. With the boom unfolded (in the spraying position) while standing on the rear side of the boom, check to ensure that the 7th pin connection in the timing chain(on the 48’ and 66’ boom)(A)(Fig. 12) is aligned with the center line between the sprocket cap screws (B)(Fig. 12).

2. To adjust timing, loosen the turnbuckles on the front and rear cables until slack.

3. Line up the chain and sprocket as indicated in step 1.

4. Adjust front and rear cable tension (Section 6.10).

35HARDI® EAGLE 3PT BOOM OPERATORS MANUAL

6.4 Alignment Of Intermediate And Outer Boom Sections

1. Unfold the boom into operating (spraying) position.

2. Holding the M12x100 adjusting bolt, loosen the lock nut (A)(Fig.14), and turn nut (B)(Fig. 14) so the cap of the bolt head (C)(Fig. 14) contacts the top stop plate with the outer and intermediate boom sections aligned.

3. Check to ensure that the lock nut is tight.

Fig. 14

6.3 Alignment Of Wing Assemblies

1. With the boom unfolded (in the spraying position), check the alignment

of the intermediate section with the center frame.

2. With the fold cylinder pressurized, determine if the intermediate

section needs to be adjusted to the front or rear to come into alignment with center frame.

Note: Because of adjustments made later, it is better to start with the

wing assemblies angled slightly to the rear.

3. Relieve pressure from cylinder by folding the boom in a few inches.

4. Disconnect cylinder rod eye (B)(Fig. 13) from the intermediate boom

section.

Note: Some cylinder rods

have a machined flat which, if visible, can be used for adjustments. If using the machined flat for adjustment, leave the rod eye pinned to the boom and loosen the jam nut.

5. Loosen jam nut (A)(Fig.

13) and adjust the rod eye (B)(Fig. 13) IN to move the boom forward or OUT to move the boom rearward. Then retighten the jam nut (A)(Fig. 13).

6. Reattach the cylinder rod to the boom and pressurize the cylinder to

check boom alignment.

Fig. 13

36 HARDI® EAGLE 3PT BOOM OPERATORS MANUAL

6.5 Adjusting Front Fold Cable

The performance of the EAGLE 3 Point Boom, while spraying, depends greatly on the front fold cable adjustment. A correctly adjusted cable will also control the movement of the outer wing section.

WARNING:

THE REAR CABLE CAN SNAP AND INJURE YOU OR SOMEONE ELSE IF TENSIONED WHEN THE BOOM IS UNFOLDED. ALWAYS ADJUST THE

FRONT CABLE FIRST WITH THE BOOM UNFOLDED AND REAR CABLE LAST WITH THE BOOM FOLDED IN TRANSPORT POSITION.

1. Unfold boom into operating position.

2. Shut the tractor off.

3. Check the security of turnbuckle anchors to the hinge.

3. Slide a straight edge down the underside of the intermediate boom section until it just contacts the front cable.

4. Suspend a 10lb (4.5kg) weight from the straight edge-to-cable contact point and check deflection by measuring the distance from the straightedge to the cable. Cable should deflect .50-.75 in. (13-20mm).

5. Loosen jam nuts (A)(Fig. 15) on the turnbuckle assembly and adjust turnbuckle (B)(Fig. 15) for proper cable deflection.

6. Tighten jam nuts (A)(Fig. 15) and remove weight.

IMPORTANT:

Check boom alignment again. If front cable was tightened, the wing assembly will move forward; or if loosened, wing will move rearward. Adjust fold cylinder (if necessary) as described in Aligning Wing Assemblies, (Section 6.3).

6.6 Adjusting The Breakaway Clutch

WARNING:

NEVER PLACE FINGERS INTO THE OPEN BREAKAWAY CLUTCH OR YOU MAY BE INJURED SHOULD THE CLUTCH SNAP CLOSED! DO NOT TIGHTEN THE BREAKAWAY CLUTCH MORE THAN WHAT IS NECESSARY! OVER TIGHTENING CAN CAUSE DAMAGE TO THE BOOM!

The tension on the breakaway for the outer wing can be adjusted by loosening or tightening the adjustment nut on top of the sprocket between the inner and outer wings (Fig. 16).

1. If the breakaway clutch releases too easily, tighten the nut.

2. If the breakaway clutch is too stiff, loosen the nut.

Note: Spring pressure from tensioned breakaway clutch only assists in

returning outer boom section to alignment.

3. Check that the lower nut (D)(Fig. 16) is fully tightened.

4. The breakaway wing section should pivot around the axle shaft (E)(Fig. 16). Ensure that section (F)(Fig. 16) is free to move.

5. Loosen jam nut. (B)(Fig. 16).

6. Tighten nut (C)(Fig. 16) to stiffen clutch action. Clutch is properly tensioned when breakaway boom section returns to alignment with outer boom section after breaking away. Tighten jam nuts after adjustment.

IMPORTANT:

Properly lubricate clutch assembly before adjusting the tension. Breakaway clutch cap screws (A)(Fig. 16) must be torqued to 40lb-ft (55 N-m) every week (40 hours) to prevent boom damage. Lubricate every day (8 hours) to ensure maximum performance and life.

6.9 Adjusting the Boom Transport Position

1. Lift the boom all the way to the top.

2. Fold the boom into the transport position. With the fold cylinder pressurized, determine if the boom sections need to be adjusted inwards or outwards.

Note: Ensure that the boom wings will not interfere with the tractors

wheels or structure.

3. Relieve the pressure from the fold cylinder by unfolding the boom a few inches.

4. If the boom comes too far in towards the tractor cab, loosen the nut (B)(Fig.20) and adjust collar (A)(Fig.20) in towards the cylinder housing.

If the boom goes too far out away from the tractor cab, adjust the collar (A)(Fig.20) away from the cylinder housing.

6. Secure the jam nut (B)

(Fig.20)

7. Pressurize cylinder to see if the boom

is properly adjusted. If not,

repeat the above procedure until it is correctly

adjusted.

6.8 Adjusting The Center Section

This adjustment will affect the suspension (trapeze function) and must therefore be done properly to optimize the EAGLE 3 Point Boom performance.

IMPORTANT:

Lubricate pivot linkage and grease skid plates prior to

adjustment .

1. Ensure that the sprayer is on level ground.

2. Tighten the four adjustment bolts (A)(Fig.19) approx. 1/2 turn.

3. Grasp the wing by the end and lift it approx. 20 in.(490mm). Release the wing and it should smoothly return to approximately the horizontal position.

4. If the trapeze will not let the boom go back to horizontal position, the bolts must be loosened again. The spray boom is properly adjusted when it returns to the horizontal position under its own weight.

The assembly, operation and maintenance required for these kits is covered in this section.

8.1 P.T.O. Shaft Operator Safety

WARNING: ALWAYS STOP ENGINE BEFORE ATTACHING THE

TRANSMISSION SHAFT TO TRACTOR P.T.O. - MOST TRACTOR P.T.O. SHAFTS CAN BE ROTATED BY HAND TO FACILITATE SPLINE ALIGNMENT, WHEN ENGINE IS STOPPED.

When attaching the shaft, make sure that the snap lock is FULLY ENGAGED - push and pull shaft until it locks.

WARNING: ROTATING TRANSMISSION SHAFTS WITHOUT

PROTECTION GUARDS ARE FATAL.

Always keep protection guards and chains intact and make sure that it covers all rotating parts, including CV-joints at each end of the shaft. Do not use without protection guard. Do not touch or stand on the transmission shaft when it is rotating - safety distance: min 5' (1.5 meters). Prevent protection guards from rotating by attaching the chains allowing sufficient slack for turns.

Always STOP ENGINE and remove the ignition key before carrying out maintenance or repairs to the transmission shaft or implement.

50 HARDI® EAGLE 3PT BOOM OPERATORS MANUAL

Note: Adjust the constant distribution boom pressure one section at a

time as follows:

(Start with the valve turned closed before

adjusting).

1. Shut-off the first boom distribution valve switch (B) (Fig.33).

2. Turn the adjusting screw (1) (Fig. 32) until the control unit pressure gauge (7) (Fig. 32) again shows the same pressure as set in step 6 above. (Turn the screw clockwise for higher pressure, counterclockwise for lower pressure).

3. Turn the first boom distribution valve switch (B) (Fig. 33) back on.

4. Repeat steps 7 through 9 for the remaining boom distribution valves.

Note: Hereafter adjustment of the constant boom pressure will only be

needed if you change to nozzles with other capacities, but not required if only changing pressure or application rate using the same nozzles.

5. Operating the EC control unit while driving: In order to shut off the entire boom activate on-off switch (A) (Fig.33). This returns all the pump outputs to the tank through the return system. The diaphragm anti-drip valves ensures instantaneous closing of all nozzles.

In order to shut off one or more sections of the boom, switch one or more unneeded boom distribution valves (B) (Fig.33) to off position. The constant pressure device ensures that the pressure does not increase in the sections which are still operating.

In case of electrical failure it is still possible to manually overide all functions of the operating unit. To operate manually, disconnect the multiplug from the EC control box first and operate the handles by hand. It is possible to change pressure, turn boom sections on or off, or shut off the complete control unit manually.

IMPORTANT:

When the sprayer is stored, the EC control box and

the multiplug must be protected against moisture and dirt. A plastic bag may be used to protect the multiplug. Store the control box in a clean dry place.

8.5 Adjustment of Constant Pressure

51HARDI® EAGLE 3PT BOOM OPERATORS MANUAL

8.6 Agitation Adjustment (Agitation nozzles only)

Fig. 34

Agitation is necessary to keep the solution in your tank properly mixed. Consult your chemical supplier for the recommended amount of agitation.

In general, maximum agitation is required but some products tend to foam easily. To reduce foaming in some instances anti-foaming agents may be added to the tank (Refer to chemical label). When running low liquid levels in the tank, agitation may be reduced to facilitate pump priming and avoid pressure fluctuations. Make sure that you have adjusted the agitation properly before sprayer calibration.

Turning the Agitation Valve (A ) (Fig.34) clockwise will reduce the agitation flow. Turning the valve counter clockwise will increase the agitation flow.

6. Filter housing cover nut

This filter automatically flushes out particles and chemical deposits, reducing routine maintenance, nozzle plugging and operator exposure.

No adjustments are required but different mesh screens may be installed for various types of products. A good practice is having the necessary new O-rings on hand at the time of changing screens or when performing routine maintenance. O-ring part numbers are #242020, #241953, #242047.

Note: It is advisable to have the sprayer tank empty before carrying

out any maintenance on the self-cleaning filter.

To clean or replace filter, loosen nut (6) (Fig.35) to remove filter housing cover (3) (Fig.35) lift filter screen out. Replace screen and filter housing cover. Press down on cover (3) (Fig.35) and turn the cover nut (6) (Fig.35) clockwise until snug.

9.2 Storage of the EAGLE 3-Point Boom

WARNING:

DO NOT DISCONNECT CENTER FRAME FROM TRACTOR WITH WINGS UNFOLDED OR REMOVED. CENTER FRAME WILL BE UNSTABLE AND COULD RESULT IN PERSONAL INJURY.

Ensure that all stands are locked in the down position before removing the spray boom from the tractor.

After use, clean the sprayer according to the instructions given with the chemical used.

Store sprayer in a safe dry location away from children and animals. Protect from direct sunlight.

TO PLACE SPRAYER IN STORAGE:

a. Lower parking stands into position. (refer to Fig. 45) b. Lower the tractor 3-point hitch lift arms to park the boom on its stands. c. Disconnect sprayer hydraulics from tractor hydraulics. d. Disconnect PTO shaft & control wires from the tractor (If so equipped). e. Disconnect solution hoses from tractor to sprayer. f. Remove 3-point hitch frame from the tractor.

Fig. 45

62 HARDI® EAGLE 3PT BOOM OPERATORS MANUAL

9.3 Winter Storage

When the spraying season is over you should devote some extra time to cleaning and preparing the sprayer for storage.

Hoses

Check that none of the hoses are caught or have sharp bends. A leaky hose can give an annoying delay in the middle of the spraying job. Therefore check all the hoses and change them if there is any doubt about the physical condition.

Paint

Some chemicals are very hard on paints. It is therefore recommended to remove rust, if any, and then touch up the paint.

EC Operating unit (When fitted)

When the sprayer is put away the control box and the multi-plug must be protected against moisture and dirt. If possible use a plastic bag to cover the plug.

PTO Transmission Shaft (If applicable)

Check that the transmission shaft is in good working condition, e.g. that the shield and protective tubes are in place and in good condition.

Anti-freeze Precaution

If the EAGLE 3 point boom is not stored in a frost-free place, you should take the following precautions:

1. Drain as much water as possible from spray boom hoses and

nozzle tubes.

2. Pour in a mixture of ethylene glycol base anti-freeze and water at

the ratio for the desired temperature protection ( Volume of mixture should be about 1% of tank volume).

3. Run the sprayer and circulate the anti-freeze in the pump, controls

and boom lines. The anti-freeze solution prevents the O-rings and gaskets from drying out.

WARNING:

NEVER USE OIL OR DIESEL FUEL IN A SPRAYER.

Remove nozzles and screens. Clean and store in a safe, dry location away from children and animals. Remove pressure gauges and store upright in a warm dry location.
