FLOWMETER MAINT.
Flowmeters can become clogged with chemicals. Dirty
flowmeters are not warrantable ( top photo at right shows a
flowmeter with some chemical residue in the turbine area)
The flowmeter should be cleaned daily with TY16041 Brake
and Parts Cleaner, as shown in the photo at bottom right.
The flowmeter and entire solution system should be rinsed
with clean water daily.
HYDRAULIC TREAD ADJUST MAINTENANCE
TY25398
The tread adjust system contains special alloy wear pads that
will wear slightly with each use of the tread adjust. Periodic
readjustment of the tread adjust pads is considered normal wear
and tear. and is not warrantable. Replacement of the pads due to
wear might be necessary in situations where the tread adjust is
used frequently.
Oil, grease or other lubricants should not be used on the
machined axle surfaces ( see photo). Use of such products
will attract dirt and cause accelerated wear to the pads and
axle surfaces.
Planetaries
•Replace lube at first 50 hrs.
•Replace lube at every 500 hrs.
•Use TY26372 lube

Removing Air from Wet Booms
•Fill solution tank with approximately 125 gallons of water.
•Unfold and lower boom for access to nozzles.
•Turn off all nozzle bodies except for the last nozzle body furthest from the machine
centerline on all pipe assemblies. Remove the spray tip from these nozzle bodies. There are
two assemblies on the inner wings, one on the outer wings, and one on the breakaway
sections. One of the outside nozzles on the center section can be turned on.
•Lower the center section and tilt both boom wings all the way up.
•Run the sprayer in manual spray mode at 620.6 kpa (90 psi).
•Cycle sprayer operation through at least three ON-OFF cycles as follows to bleed trapped
air from the booms:
•Set Master ON/OFF switch to ON and watch for water discharge from open nozzle
bodies.
•Set Master ON/OFF switch to OFF and allow machine to sit for AT LEAST 15 seconds in
OFF mode to allow air to move to high points.
•Watch the discharge from each open nozzle body for smooth uniform output. Repeat ONOFF spray cycle until output is uniform. Continue spraying until only 50-75 gallons of water
remain in the tank.
•Rotate all nozzle bodies to spray position. Reinstall spray tips previously removed.
Traction Control
SPRAYSTAR OPERATIONS
Spray Setup
SPRAYER SETUP
Application Rates 1, 2, or 3 —Where the target application rates are programmed into SprayStar.
Minimum Pressure —Where the minimum pressure is programmed into SprayStar. Minimum
pressure is the minimum pressure maintained while spraying.
Spray Off Pressure —Where the spray off pressure is programmed into SprayStar. Spray off
pressure is the pressure maintained while not spraying. Typically used to maintain high pressure
setting for agitation when not spraying. It should not be used as a means for boom charge
compensation.
Tank Volume —Where tank volume is programmed into SprayStar.
High Flow Rate ON/OFF —Allows the operator to turn ON/Off the high flow rate.
Spray System MIN MAX —Allows the operator to adjust the response time of the SprayStar rate
control.
Boom Charge —Allows the operator to charge the boom at an automatically calculated pressure
(Boom Charge Pressure) for 3 seconds after the master ON/OFF switch (A) is pressed “ON”.
Foam Marker — Allows the operator to change setting of foam marker from AUTO HIGH, AUTO
LOW, MANUAL HIGH, MANUAL LOW, and OFF.
Eductor Mode — Allows the operator to select eductor pressure mode from Low, Medium, and
High settings.
Boom Pressure Relief —Allows the operator to activate the boom pressure relief feature.
Alarm Setup — Allows the operator to turn on or off a flow rate error, sections off and ladder
alarms.
Setting Minimum Pressure
Setting Minimum Pressure
Determine and set the minimum pressure required using the following procedures:
•Unfold booms.
•Turn all boom spray section switches on.
•Select the Setup softkey (A) to view the setup menu.
•Select the Spray Setup tab (B).
•Select input box (C) next to “Min Spray Press. (psi)” to be changed and enter a new
value using pop-up keyboard (D). Enter 0. Select the enter button (E) to accept new
value.
•Turn rate control switch to manual pressure setting “MAN”.
•Select input box (F) next to “Spray Off Pressure (psi), to be changed and enter a new
value using pop-up keyboard (D). Enter 0. Select the enter button (E) to accept new
value.
•Turn on solution pump and master spray switch.
•Increase “Spray Off Pressure” by 6.9 kPa (.07 bar) (1 psi) increments until all nozzle
body check valves open and all nozzles are spraying at full pattern. Note pressure when
this occurs.
•Select input box (C) next to “Min Spray Press. (psi)” to be changed and enter a new
value using pop-up keyboard (D). Enter pressure from previous step. Select the enter
button (E) to accept new value.
Setting Spray Off Pressure
Setting Spray Off Pressure
•Select the Setup softkey (A) to view the setup menu.
•Select the Spray Setup tab (B).
•Select input box (C) next to “Spray Off Press. (psi)” and
enter a new value using pop-up keyboard.
•Select the enter button to accept new value.
Enabling High Flow Rate
Enabling High Flow Rate
•Select the Setup softkey (A) to view the setup menu.
•Select the Spray Setup tab (B).
•NOTE:
•A check mark in the box indicates that High Flow Rate is activated.
•Select check box (C) next to “High Flow Rate ON / Off” and a check will appear
inside box activating item. To deactivate a check box, touch check box to
remove the check.
•NOTE:
•When High flow rate is turned “ON” in SprayStar the flowmeter valve must be
opened on boom. If SprayStar and flowmeter valve settings do not agree:
•Flowmeter valve open but SprayStar High Flow “OFF ” — will overapply
•Flowmeter valve closed but SprayStar High Flow “ON ” — will underapply
Applying Low Application Rates
Applying Low Application Rates
•When applying low application rates, it may be necessary to turn orifice valve (A) to
the closed (low) position.
•To determine when to close orifice valve, calculate boom flow rate. When solution
flow rate is 100 Lpm (26 gpm) or less, close the orifice valve. If solution flow rate is
greater that 100 Lpm (26 gpm) open orifice valve all the way.
•Determining Solution Flow Rate:
•When spraying, go to Sprayer Main Page and check solution flow rate (B) if that
feature has been selected on one of the dropdown menus available on that page. If
solution flow rate is 100 Lpm (26 gpm) or less, close the orifice valve. If solution flow
rate is greater than 100 Lpm (26 gpm) open orifice valve all the way.
•Determine size of nozzles and multiply by the total number of nozzles on the boom. If
solution flow rate is 100 Lpm (26 gpm) or less, close the orifice valve. If solution flow
rate is greater that 100 Lpm (26 gpm) open orifice valve all the way.
•Example: If 8003 type nozzles are installed and there are 54 on the boom: 0.3 gpm x
54 = 16.2 gpm (solution flow rate).
•Operator would close orifice valve.
Setting Sprayer Response
Setting Sprayer Response
•The Sprayer Response allows the operator to adjust the response time of the SprayStar
rate control. This is the time it takes the actual application rate to reach the target
application rate in auto mode.
•The response time has five different settings. A “5” indicates the fastest response time
(MAX) and a “1” indicates the slowest response time (MIN). Each step down from “5”
requires more response time to adjust to the target rate.
•For almost all situations, the response time should be set at “3” for all 4730 and 4830
sprayers. If a different boom is installed, or an unusual configuration on a John Deere
boom is installed, the response time may have to be reduced or slowed.
•When To Change The Response Time Setting:
•When the target application rate is never reached increase response
•When the application rate is erratic decrease response
•When the time it takes the actual application rate to reach the target rate is quite long,
approximately more than 4 seconds increase response
•To change the response time do the following:
•Select the Setup softkey (A) to view the setup menu.
•Select the Spray Setup tab (B).
•Select drop-down box (C) next to “Spray System MIN MAX”
and select the new value.
Setup Boom Charge
Setup Boom Charge
•A - Master Spray ON/OFF Switch
Boom charge allows the operator to charge the boom at a manually specified or
automatically calculated pressure (Boom Charge Pressure) for 3 seconds after the Master
Spray ON/OFF switch (A) is pressed “ON”. After 3 seconds, the automatic rate control
system will take over. This allows the spray rate control system to reach the target
application rate faster when smaller flow rate nozzles are used.
•In SprayStar setup, place boom charge in “AUTO” when solution flow rate is under 100 Lpm
(26 gpm).
•To Determine Solution Flow Rate:
•When spraying, select gallon per minute item from one of the drop-down menus on the
Sprayer Main page
•OR
•Determine size of nozzles and multiply by the total number of nozzles on the boom.
•Example: If 8003 type nozzles are installed and there are 54 on the boom: 0.3 gpm x 54 =
16.2 gpm (solution flow rate). Operator would need to turn boom charge on AUTO.
Relieving Boom Pressure
The Boom Pressure Relief function allows the pressure trapped in the boom to be
bled off after spraying is complete. The pressure is bled off by allowing the boom
sections valves to be opened for approximately 3 seconds after the solution pump
and remote load are shut off. It is recommended that the operator raise the boom
center frame to its highest position. The solution pressure must be 4 psi or less
and the engine is running for function to operate. The operator must press the
Master Spray ON/OFF button to activate the function. After the 3-second period, the
boom section valves will close. The main purpose of this function is to minimize
the possibility of the sprayer nozzle bodies leaking while in transit.
1. Select the Setup softkey (A) to view the setup menu.
2. Select the Spray Setup tab (B).
NOTE: A check mark in the box indicates that "Boom Pressure Relief" is activated.
3. Select check box (C) next to "Boom Pressure Relief" and a check will appear inside box
activating item. To deactivate a check box, touch check box to remove the check.
4. Set Solution Pump ON/OFF switch to the OFF position.
5. If not already in the OFF position, set all Remote Load Switches to the OFF
position.
6. If not already in the fully raised position, raise boom center frame to fully
raised position. Boom can be folded or unfolded.
7. Press Master Spray ON/OFF, after pressing Master Spray, the operator should
hear an audible alarm and see the message (A) "RELIEVING BOOM PRESSURE"
displayed.
Flowmeter Shut-off Valve
Flowmeter shut-off valve (A) allows the operator to close the pressure
line when cleaning the flowmeter(s). Closing the pressure line limits the
amount of solution that drains and limits the amount of air introduced to
the system.
To open, rotate handle parallel to solution hose as shown.
To close, rotate handle perpendicular to solution hose.
A-Flowmeter Shut-off Valve
Solution Pump is Dry- Turn Off Pump Immediately
This alarm is set when the SprayStar controller detects that solution pump
switch is on and the solution pressure is less than 7 psi (48 kPa) for more
than 3 seconds with the pump operating at a speed greater than 70% of the
maximum pump rpm. This alarm will be cleared/reset at power-up, if the
solution pump is turned off, or if the solution pressure is greater than 7 psi.
Audible Alarm: Continuous Audible Alarm
Never hit reset to factory default settings (button C)

Vari-Cool fan
The Vari-Cool fan drive system precisely
controls the speed of the fan in relation to
the cooling requirements to maximize
efficiency of the engine. The Vari-Cool
system is efficient for two primary reasons:
The belt drive used in the Vari-Cool system
transfers almost 100 percent of the power
from the engine to the fan.
The variable fan speed sheave is
electronically controlled, only operating at
the necessary speed to cool the engine
and other auxiliary components.

•Fully John Deere Supported
Direct Injection Benefits
•
Allows for mixing of chemical at time of use, instead of tank mixing
•
Inject chemical into the carrier flow at a specified application rate
•
Rate of chemical can be changed during field application (+/-), if necessary.
•
Can apply different products in same field as chemicals are needed, when
multiple pumps are used. (example - spot spraying).
•
Can Eliminate the need to mix chemicals in the sprayer solution tank
•
Can Eliminate the need to rinse the sprayer solution (carrier) tank prior to
switching chemicals
Wheel Slip Control
Wheel slip prevents losing tractive effort; it
does not increase the power. When a
wheel starts spinning out, wheel-slip
control automatically diverts power to the
other three wheels until all four wheels are
turning at the same speed.
Not available above 15 mph
Software will not take a slipping motor to “0” cc’s as before,
instead it will adjust to lower flow based on rpm from wheel
speed sensors on all wheel.
Software then looks a Radar/GPS for comparison.
Software will adjust all motors in “steps” to maintain motion.
By doing this the wheels will continue to move and the result
is a machine that in tests would climb just about anything.
IT4 Engine
The 4940 Sprayer comes with the 9.0 L PowerTech™
PSX engine delivering 250 kW (340 hp) with a 10 percent
power bulge to 275 kW (374 hp).
The John Deere PowerTech PSX 9.0L engine in the 4940
is extremely quiet at idle due to pilot injection, a small
amount of fuel injected early in the combustion chamber
that lessens combustion knock heard in diesel engines.
The John Deere-exclusive single injector control,
electronic fuel-injection system, and other key engine
parts work together to sense engine load and then
instantly respond as needed
Sprayer Tips
• John Deere offers spray products for a variety of pressure ranges,
flow rates and spray patterns to fit any spray process. Spray tips are
available in materials including: ceramic, polyacetal , Polyvinylidene
Fluoride (PVDF), stainless steel and brass.
