Safety Information

GENERAL SAFETY (4.1)

Dawn Equipment Company strongly recommends

adhering to a comprehensive and effective safety

protocol when transporting, maintaining, and/or

operating any agricultural implement. A 2008 study

from the United States Dept. of Labor

(http://www.bls.gov/news.release/cfoi.t02.htm) states

that farm related fatalities account for almost 10% of

the total number of work related fatalities in the U.S..

Additionally, the loss of a limb, or other bodily

disfigurement, may permanently affect your ability to

carry out the requisite duties necessary to maintain a

profitable farming operation. Please take all

appropriate precautions to keep you, your family, and

your farm safe!

DEFINITIONS (4.2) - (Ref: ASAE S441.1)

It is essential that you be able to recognize safety

signal words and their associated colors. Please be

alert to any signs posted on your Dawn Equipment

Company products, and/or in your users manual.

Make sure you have read all safety messages and

that you clearly understand the recommended

precautions. If you have questions about any Dawn

safety sign, or have further questions about safety

recommendations on this or any other Dawn product,

please contact us at 800.554.0007.

Danger - Indicates an imminently hazardous

situation that, if not avoided, will result

in serious injury or death. (RED)

Warning -Indicates a potentially hazardous

situation that, if not avoided, will result in

serious injury or death. (ORANGE)

Caution -Indicates a potentially hazardous

situation that, if not avoided, may result

in minor or moderate injury. (YELLOW)

Hazard -A source of potential injury to a person.

A complete list of Dawn Equipment Company safety

signs with explanations can be found in the appendix

of this manual, or any other Dawn Equipment

Company users manual. Please review and

understand all safety signs.

PROTECTIVE CLOTHING (4.3)

Wearing proper attire when working on agricultural

equipment is a critical safety precaution. Loose

clothing or accessories may become entangled in

moving parts causing serious injury or death. Please

ensure that loose cuffs, shirts, belts, jewelry, etc. are

secured such that they cannot be snagged on, or be

drawn into, moving machinery.

Make sure that all necessary protective accessories

are readily available, this will increase the likelihood

they are used when needed. Stay aware of your

surroundings when in the proximity of machinery that

is either moving or has the potential for spontaneous

movement.

PROTECTIVE ACCESSORIES (4.4)

It only takes one accident to permanently curtail your

performance in the field and on the farm. Equip

yourself with all recommended safety accessories,

and develop a strategy for ensuring their use when

needed.

Safety Information

Safety Glasses / Goggles

If you will be using hazardous

chemicals, or are striking, cutting

or grinding metal make sure you

are wearing eye protection.

Earplugs / Sound Mufflers

When working around equipment

that generates high amplitude

sound (ie , dryers, vacuums),

ear protection is strongly

recommended.

Respirator Mask

Please carefully read all safety

information associated with any

chemicals you will be handling. Use a

respirator mask when using hazardous

chemicals, (ie Insecticides, NH3

Work Gloves

If working around machinery with

sharp edges, or rough metal surfaces,

work gloves may prevent a few

stiches. Work gloves are inexpensive,

and are really worth the investment.

Steel-Toed Boots

A good pair of steel-toed boots

can save your toes! Avoid an

unfortunate accident, and protect

your feet.)

First Aid Kit

Every shop and tractor

should have a complete

first aid kit.

REPORTING AN EMERGENCY (5.2)

Ensure that you have access to a radio or mobile

phone when operating or repairing farm machinery.

Working with a partner whenever possible significantly

increases the chances of receiving timely emergency

care should one party become severely injured,

and/or incapacitated.

Tractor Preparation

TRACTOR TIRES (6.1)

In general, set the tractor tires (center to center) at 4x

the row spacing (exe. 120” center to center for 30” row

spacing). The minimum row spacing for the Pluribus

Unit is 22”. Make certain that the tires are inflated to

the recommended pressure for your conditions.

The majority of Pluribus Strip-Till users run on 30”

centers, and split the previous years rows. This

typically places the tractor tires running over stalks.

You may want to consider an aftermarket tool

designed to flatten the stalks and reduce tire wear. If

you are equipped with high precision guidance, you

may also consider running at an angle to the previous

years rows. The practice of running at an angle can

also have additional performance benefits in some

conditions.

LIFT CAPACITY (6.2)

Due to the low horse power requirements of the

Pluribus unit, many users will opt for a smaller tractor

to pull the implement. One important factor to

consider, however, is the lift capacity of the tractor

hitch. Each Pluribus unit can weigh in excess of 700

lbs.. If you will be using a mounted toolbar, please

ensure that your tractor is capable of easily lifting the

combined weight of the toolbar, the strip-till units and

any additional fertilizer distribution equipment. Should

your lift capacity be adequate, there is still a potential

that you are excessively tail heavy. If you have

difficulty steering in the transport position, you may

have to add weight to the nose of the tractor.

WARNING!: Driving uphill with a tail heavy tractor is

dangerous! Tractors with excessive tail weight are

susceptible to rollovers.

(Note: The procedure for determining lift capacity on a

tractor equipped with a 3-point hitch can be found in ASAE

S349.2)

THREE POINT HITCH (6.3)

If you have a mounted tool bar, you will want to ready

your 3-Point hitch. Hitches that have seen little use

can freeze up. It is recommended that your free up all

your links in preparation for toolbar leveling

adjustments. Additionally, it is recommended that you

install an aftermarket hydraulic upper link so that you

can quickly adjust the toolbar pitch as field conditions

change.

TRACTOR DRAWBAR (6.4)

The industry standard for tractor drawbars is

approximately 17.5” above ground level. Not all

manufacturers adhere to this standard, nonetheless it

is very important that the toolbar be hitched in such a

way that it can be easily leveled fore and aft. If you

are unable to connect your toolbar in such a way that

it can be easily leveled, please contact Dawn for

advice on your particular tractor/toolbar configuration.

Make sure the drawbar has eyelets for safety chains.

Pulling an agricultural implement without safety chains

is dangerous!

TRACTOR HYDRAULIC SYSTEM (6.5)

Understanding your tractor hydraulic system is

critically important, and you should thoroughly

familiarize yourself with the hydraulic system

instructions provided by the tractor’s manufacturer.

HYDRAULIC PRESSURE (6.5.a)

Know the maximum operating pressure of each

hydraulic component. Exceeding the recommended

pressure can result in equipment damage or failure.

Pressure recommendations can be found in the users

manual of most agricultural implements. Also ensure

that there is adequate pressure, should you have a

system that employs multiple hydraulically driven

components.

HYDRAULIC VALVES / COUPLERS (6.5.b)

Hydraulic cylinders are susceptible to abrasion due to

impurities in the hydraulic fluid. It is recommended

that you use a clean cloth to remove any abrasive

particulate that may have collected in and around the

valve plug, and the connecting socket. Always keep

dust covers in place when valve is not in use. Test

your hydraulic hoses and couplers. Make sure there

are no leaks.

WARNING!:

Hydraulic fluid under pressure is

dangerous! Small holes in hydraulic lines may eject

streams of fluid at high pressure. Hydraulic fluid that

penetrates the skin can cause serious infection that can

lead to amputation. Should oil penetrate your skin, even

if it is relatively painless, seek immediate medical

attention.

Toolbar Preparation

NOTE: With row by row hydraulic downforce, it is

likely that extra weight, or weight distributing hydraulic

cylinders will be required to keep toolbar wings at

proper operational height /angle. Weights should be

added near the ends of the toolbar.

TOOLBAR TIRES (7.1)

If your toolbar was built for the purpose of carrying

striptill equipment, tires on the toolbar should be

properly placed without any correction needed. Many

users will opt for a used planter, or cultivator toolbar.

These toolbars can sometimes work, but gauge

wheels must run in front of the toolbar. Toolbars with

gauge wheels running between strip-till units will not

perform properly. Check that your tires are properly

inflated to the recommended pressure for your

conditions.

HARDWARE INSPECTION (7.2)

Ideally, every piece of equipment, every fastener, and

every accessory is perfect right out of the box. In the

real world, there is a occasional bolt that is not snug,

and an occasional fitting just slightly out of spec. It is

important to inspect your entire system, to ensure that

every bolt is tight and every component is functioning

properly. This simple step can significantly reduce

downtime due to small imperfections amplifying into

equipment failure.

HYDRAULIC INSPECTION (7.3)

Today’s hydraulic systems make setup relatively safe

and easy, but it is still important to check all hydraulic

lines and fittings before connecting them to the

tractor. It is recommended that all couplers be fitted

with dust caps when not in use, and carefully cleaned

before connecting. Check for damage on all hydraulic

hoses and replace any lines that have been

compromised by wear or fatigue. High pressure

hydraulic fluid can be dangerous if couplers, lines and

fittings are not properly installed and cared for.

HYDRAULIC CONNECTIONS (7.4)

You should inspect the hydraulic hoses and their

connections. Make sure that the fittings, running into

actuator, center manifold, and all hoses are secure.

Please read and understand the users manual of any

hydraulic accessories and connect pneumatic fittings

according to the recommendations of the

manufacturer.

TOOLBAR MOUNTED EQUIPMENT (7.5)

Many toolbars used in conjunction with the Pluribus

system carry a number of additional agricultural

devices. Fertilizer hoppers, fertilizer distribution

systems, pneumatic accumulators and pumps, etc.

should be inspected and checked for loose

connections whether electrical, hydraulic or

mechanical. If you do not have an operators manual

for an agricultural device you will be using with the

Pluribus Strip-TIll System, it is highly recommended

that you obtain and review the equipment manual

before using it.

TOOLBAR HITCH (7.6)

Both drawbar and three-point hitches should be

checked for fatigue. Pull-type toolbar hitches should

be equipped with safety chains. Safety chains can

prevent a serious accident should the toolbar hitch

become disconnected from the drawbar.

WARNING!:

Unsecured agricultural implements

can move erratically with extreme force, and may

cause serious injury or death.

Tractor / Toolbar Connections

HITCHING (8.1)

When you have thoroughly prepared your tractor and

toolbar, you are ready to hook-up. There are a wide

variety of hitch configurations, and it is recommended

that you familiarize yourself with the operation of your

hitch. Operational instructions for your hitch type

should be found in the users manual of both your

tractor and toolbar.

3-POINT HITCH (8.1.a)

Most 3-point hitches will be either Category 2 or

Category 3 hitches. If you have a category 2 hitch,

make sure that your toplink pin is 1” dia. and your lift

arm pins are 1 1/8” dia.. If you have a category 3

hitch, make sure that your toplink pin is 1 1/4” dia. and

your lift arm pins are 1 7/16” dia.. In some cases you

will have to remove, or relocate the tractor drawbar.

If the lift arm is equipped with an extension, release

the lock and pull the extension out its full length of

travel. Slowly back the tractor up to the toolbar until

the lift arms are aligned with the lower hitch pins.

Raise or lower the lift arms until the eyelets are

concentric with the lower hitch pins. Stop your tractor

and engage the parking brake to prevent rolling when

pinning the lift arms to the hitch. Pin each lift arm in

place and install a spring clip. Restart the tractor and

slowly raise the lift arms until the eyelet of the upper

link is concentric with upper hitch pin. Once again

stop the tractor and engage the parking brake. You

may have to lengthen or shorten the upper link to

install the hitch pin. After installing the upper hitch pin,

make sure to secure it with a spring clip. If you have a

“quickhitch” variety 3-point hitch, as before slowly

back up to the toolbar until the lower clasps of the

quick-hitch rest below the lower hitch pins. Lengthen

or shorten the upper link to align the quick hitch with

the hitch pins. Raise the quick-hitch until it engages

the hitch pins. Make sure the hitch retainers are

lowered, and engaged.

DRAWN HITCH (8.1.b)

Slowly back up the tractor to the toolbar until the

tractor drawbar is near the clevis of the toolbar. Stop

your tractor and engage the parking brake. Use the

toolbar jack to align the clevis with the tractor drawbar.

You may have to reposition the clevis. The lower hitch

panel of the clevis should be approximately 14 in.

above ground level, so that the upper hitch panel rides

abutting the tractor drawbar. Most toolbars have

optional settings for the clevis. Once the height of the

clevis is aligned with the tractor drawbar, slowly back

the tractor until the pin holes of the clevis and drawbar

are aligned. If you are using assistance in hitching the

toolbar, please make sure no person is between the

tractor and the toolbar when in motion.

WARNING!:

Tractors in motion may behave

erratically! Persons caught between a tractor in

motion and an agricultural implement could suffer

serious injury or death.

When you have aligned the pin holes, install the

appropriate pin and secure it with a spring clip. Your

toolbar should be equipped with safety chains. Make

sure to connect the safety chains before moving the

toolbar.

HYDRAULIC CONNECTIONS (8.2)

WARNING!:

Shut off tractor and remote cylinder

controllers that are in operation before attaching or

detaching hydraulic hoses to avoid potential injury

from hydraulic fluid escaping under pressure.

Ensure that all hoses and fittings are secure before

pressurizing system. Refer to installation guides for

proper assembly. All agricultural implements

equipped with hydraulic components should be

accompanied by a users manual that details attaching

and detaching. Please carefully follow the instructions

provided by the manufacturer.

ELECTRICAL CONNECTIONS (8.3)

Check to ensure that electrical connections are

secure and properly connected. Familiarize yourself

with the users manual of any electrical components

that your strip-till/fertilizer system might employ.

Carefully read the connection procedure found in the

users manual of that components manufacturer.

The row unit controller is capable of being configured

to run multiple Dawn products simultaneously, but we

will start with the basic downforce configuration.

HARNESS INSTALLATION (11.2)

Reflex Basis Harness

Reflex Strain Gauge Harness

Reflex Strain Gauge Harness will be routed along the

parallel linkage on a planter row unit, or behind the

actuator on a striptill unit, and then connect to the

sensor on depth adjustment assembly. Make sure the

excess cable is secure to prevent damage from any

pinch points along the linkage.

ROW-TO-ROW CABLES (11.3)

Row-to-row cables can be plugged in to either 4 pin

receptacle. Ensure they are fully inserted until you

hear/feel the locking tap click into place.

REFLEX ACTUATOR VALVES (11.4)

NOTE: Ensure valve

cables correspond with

the hose routing.

Notice – Valves can be

purged by pressing the

small pin on top.

TERMINATION RESISTORS (11.5)

First and last row unit controllers require a termination

resistor (PN 90625-180) installed into the second

4-Pin receptacle.

PROXIMITY SWITCHES (11.6)

Proximity switches deactivate the hydraulic down

pressure when the toolbar is raised. They are non-

contact switches, so do not compress.

They are placed on the lower parallel casting on a JD

planter row unit. They should be loosely installed

away from the rear until the toolbar is raised and row

units are resting on the travel stop.

After the Reflex system is powered on, adjust the

distance of the prox switch from the casting, starting

with it close. Move the switch away from the plate until

the internal LED light comes on. Turn back towards

the face about 1.5-2 turns of the jam nut and tighten

with two 15/16” wrenches. This is easier done by

finger tightening the jam nuts, and lowering the bar to

create clearance for wrenches.

Select a location to install the center manifold, ideally

between the two center rows.

Plumb the pressure and return trunk lines to the

indicated ports.

Route your row-to-row hoses from the center manifold

directly to the actuators as shown in fig. xxx. Ensure

hoses do not get crossed during install. Marking the

pressure and return hoses before installation is

recommended for ease of identification.

TRUNK HOSES (12.2)

Route ½” hose down draft arms allowing enough hose

for all folding points. Cut hose to length and crimp

supplied fittings to manufacturer specifications.

ROW-TO-ROW HOSE ROUTING (12.3)

Starting for the center manifold, route hoses from the

corresponding RETURN, PRESSURE & UPLIFT

adapters to the row unit actuators. Continue along

toolbar to final rows.

Check clearance with seed tubes and vacuum lines to

prevent unnecessary wear. It is advisable to have

hydraulic hoses routed under any other tubes many

times. It may be necessary to alter the angle of the

adapters in the actuators to clear obstacles.

The first and final row actuators will require the

adapters to be replaced with supplied -8 ORB Hex

Hollow Plugs (PN 9533)

NOTE: Pressure

and return routing

may be

interchanged if

necessary, but

ensure uniformity

throughout the

system. Valve

cables will need to

match hose

routing.

WING HOSES (12.3)

Route wing hoses from outer row units on center

section, around the folding point, to the first row unit

on wing, ensuring enough slack to fold and unfold

without being stretched or pinched. Many times, it is

helpful to do this routing with the toolbar half unfolded

to visualize the routing.

Planter Hardware Installation

PLANTER HARDWARE INSTALLATION (13.1)

LOWER CLEVIS MOUNT (13.1a)

A lower clevis mount will be included in the Reflex kit.

There are three different mounts available, dependent on

the planter configuration.

NOTE: Some rows may have FACTORY INSTALLED

JD PROX SWITCH ASSEMBLIES in the same

location as the Reflex switch. In this case, the tab on

the mount plate can be bent in the opposite direction

to be installed on the left hand side of the row unit.

PRO-SHAFT PLANTERS will receive a threaded stud

(PN 103094) to provide clearance for the pro-shaft. It

will replace the bolt/bushing on the lower clevis mount

near the pro-shaft. Lower cradle will be a weldment to

provide clearance for pro-shaft. ( PN 201102).

LONG PARALLEL LINK PLANTERS will receive the

standard hardware, but will configure it as shown

below. It is important to bolt through the two front

bushing holes in the lower clevis mount.

UPPER CLEVIS MOUNT (13.1b)

Use original hardware

from previous

downforce mount to

install upper clevis

mount as shown.

STRAIN GAUGE (13.1c)

Remove the factory installed depth adjust assembly by

removing the snap ring, pulling the pin, and dropping the

assembly through the bottom of the shank casting behind

the openers. Removing one of the gauge wheel arms

makes this process simpler.

•Route strain gauge cable along casting to

prevent any wear or pinch points.

•Make sure rocker (mustache) is above

gauge wheel arms, not stuck below or

inside casting.

NOTE: WHEN INSTALLING ACTUATOR, INSERT

UPPER CLEVIS PIN FROM THE RIGHT

HAND SIDE SO COTTER PIN DOES NOT

CONTACT HARNESS CABLES.

TIP: INSTALL PROX

SWITCH PLATE AT SAME

TIME AS LOWER CLEVIS

MOUNT

Remove Pin to

Replace Depth

Adjust assembly

IMPORTANT:

Utilize the two front holes

in the casting, NOT the rear

open radius!

Use the two lower holes in

the switch mount plate to

secure to the casting as

shown.

Reflex Operating System

START UP PROCEDURE (14.1)

Once all electronic components and hydraulic

components are installed, and pressure tested, you

will be ready to start the initial setup & test procedure.

Power on the Reflex system using the PCAN switch.

You should see the LED lights on the PDM and row

unit controllers come on. If there are no lights, check

cable connections and batter cable.

Once power is established, open the Dawn Reflex

Application on your tablet.

Row unit numbers will show up at the bottom of the

window. If toolbar is raised the rows will be shown in a

white box. When lowered, the box will turn green,

indicating that the down pressure system is active.

At this point, any proximity switched should be

adjusted if they are not activating/deactivating rows

properly. (fig xxx)

ROWS WILL BE SHOWN IN WHITE WHEN TOOLBAR RAISED

ROWS WILL BE SHOWN IN GREEN WHEN TOOLBAR LOWERED

CALIBRATING STRAIN GAUGE (14.2)

Raise toolbar and ensure there is no load on gauge

wheel arms.

Tap on any row number to access the ROW UNIT

STATUS window. There will be a box in the bottom

left that says “Set zero point on all units”. Press this

once. (If done while toolbar lowered, or any gauge

wheel load on wheels, the process will have to be

redone correctly)

SETTING TARGET GAUGE WHEEL LOAD (14.3)

Gauge wheel load should be selected by running a

small test strip in the specific field and finding the

proper downforce to produce the desired soil

firmness.

Lower toolbar and establish gauge wheel load. (May

need to roll forward to get row units in the ground)

Gauge wheel load will be displayed at the bottom of

the top bars for each row.

To update the target load, select desired GWL to the

right and push the “Update Setpoint” tab to program.

Reflex Operating System

MANUAL MODE (14.4)

By pressing the

Manual Mode

tab to the left, you will

switch from targeting a consistent gauge wheel load,

to targeting a selected amount of hydraulic pressure

for all units. Rows will turn orange.

By pressing the

Gauge Wheel Load

tab, you will

switch over to displaying the Applied Down Pressure

for each row. To update the targeted pressure, select

the psi, and touch the orange tab to program.

INDIVIDUAL ROW SETTINGS (14.5)

Individual rows may be set up to your specific settings

as desired. Whether you want/need to operate rows in

manual mode, or have different GWL targets in

automatic mode.

Tap on any row number on the Global Status screen

to access the individual row’s settings. Any changes

made to Gauge Wheel Load (in automatic mode) or

Target Down Pressure (in manual mode) will apply to

only the individual row controller.

If you want an individual row’s settings to remain

unchanged while being able to update settings for all

other rows on the Global Status screen, select “

Global

commands locked

out

tab”. Press again to undo

lockout. Locked out rows will appear in a grey box on

the Global Status screen.

Reflex Operating System

TIPS USING UPLIFT ASSIST (14.5a)

1. Observe the Applied Pressure during operation.

•If the average applied pressure in

operation is less than 500 psi, increase

the uplift pressure. (Large accumulator

on the row unit actuator is pre-charged

to 500 psi, and causes instability if

running at too low applied downforce).

2. Observe the Gauge Wheel Load in operation.

•If the actual gauge wheel load is much

higher that the set target, increase the

uplift pressure.

3. If an area is known to be wet or soft, increase

uplift pressure to counter the weight of the row

unit.

WARNING!:

Always ensure that system pressure

has been relieved before opening any hydraulic

component!

OVERVIEW OF REFLEX OPERATION (14.5b)

KEY TERMS:

1:Automatic Mode – targets the user-set gauge

wheel load and applies/relieves pressure to

continuously maintain that load.

2. Manual Mode – Bypasses the gauge wheel

load and applies/relieves based on manually

entered pressure setting.

3. Gauge Wheel Load – Pressure from gauge

wheels measured by sensor at base of height

adjust assembly.

4. Applied Down Pressure – Pressure being

applied to row unit, either by automatically

adjusting to target gauge wheel load, or by

manually entering a set pressure.

Automatic mode is default setting in normal operating

conditions.
