Safety
YOU are responsible for the safe operation and
maintenance of your Degelman OnePass. YOU
must ensure that you and anyone else who is going
to operate, maintain or work around the OnePass
be familiar with the operating and maintenance
procedures and related SAFETY information
contained in this manual and with products used.
Remember, YOU are the key to safety. Good safety
practices not only protect you but also the people
around you. Make these practices a working
part of your safety program. Be certain that
EVERYONE operating this equipment is familiar
with the recommended operating and maintenance
procedures and follows all the safety precautions.
Most accidents can be prevented. Do not risk injury
or death by ignoring good safety practices.
• OnePass owners must give operating
instructions to operators or employees before
allowing them to operate the OnePass, and
at least annually thereafter.
• The most important safety device on this
equipment is a SAFE operator. It is the
operator’s responsibility to read and
understand ALL Safety and Operating
instructions in the manual and to follow
these. All accidents can be avoided.
• A person who has not read and understood
all operating and safety instructions is
not qualified to operate the machine. An
untrained operator exposes himself and
bystanders to possible serious injury or
death.
• Do not modify the equipment in any way.
Unauthorized modification may impair the
function and/or safety and could affect the
life of the equipment.
• Think SAFETY! Work SAFELY!
SAFETY
1. Read and understand the Operator’s
Manual and all safety signs before
operating, maintaining or adjusting
the OnePass.
2. Install and properly secure all shields and
guards before operating.
3. Have a first-aid kit available for use
should the need arise and know how
to use it.
4. Have a fire extinguisher available for
use should the need arise and know
how to use it.
5. Wear appropriate protective gear.
This list includes but is not limited to:
• Long sleeve shirt
• Long pants that reach the shoes
• Protective shoes, preferably chemical resistant
Also consider:
• Chemical resistant gloves
• Protective glasses or goggles
• A hat
• Face Shield
• Chemical proof apron when mixing chemicals
Note: The most important thing to remember
about Personal Protective Equipment (PPE)
clothing, gloves and shoes is that these
protection materials only work if the chemicals
remain on the outside of the material. If you
allow it to get on the inside due to a spill,
splashing or careless work, your protective
clothing actually works against you. When
this happens, it can hold the chemical against
the skin. Change any clothing that is no
longer doing what it is intended to do. Always
choose the best materials and work carefully.
Note: Familiarize yourself with the location and
use of ChemWash and ChemSpill kits.
6. Clear the area of people, especially small
children, and remove foreign objects from the
machine before starting and operating.
7. Stop tractor engine, set park brake, remove
ignition key and wait for all moving parts to
stop before servicing, adjusting, repairing or
unplugging.
8. Review safety related items with all operators
annually.
GENERAL SAFETY

-4-
142649 - OnePass Applicator (28-September-2020)
Safety
Learning to use herbicides safely is extremely important.
A careless approach will only lead to needless exposure
to yourself or others. It can also lead to non-target
damage to desirable plants.
This section will help you to better understand some
basic principles of chemical safety.
• Always read the herbicide label completely before
opening the container. To view the entire label on
some products, you must peel back the tape as
many are folded accordion style and taped closed.
• Make sure you have all the proper personal
protection equipment (PPE) that is listed on the label
before opening the container.
• Any household items used for herbicide or pesticide
use, such as measuring cups, stir sticks, etc. should
not be reused in the house. They should be thrown
out or used only for herbicide control use.
• Some herbicide solutions are concentrated and
must be diluted with another liquid (usually water)
for use. Do not add more herbicide than the
maximum rate allowed on the label. Adding more
than what is allowed will not give better control
and, in most cases, it is illegal.
• Estimate the area to be treated and try to mix only
the amount you need. Do not dump any excess, but
use the solution on the target pests (weeds, grass,
etc). If you need to clean the chemical applicator
afterwards, a mixture of ammonia and water will
break down most chemical residues left in the unit.
Never assume an applicator is perfectly clean.
• The best shoes to wear when applicating will
be made of chemical resistant rubber or plastic
materials. Don’t wear tennis shoes or other shoes
made from absorbent materials when applying
herbicides. After application, remove your shoes
before entering the house, so herbicide residue is
not tracked inside.
• Pay close attention to label instructions regarding
re-entry times. The use of certain products may
require that people or pets stay out of the treated
area for a specific amount of time.
• Store all herbicides and pesticides, application
equipment, and mixing containers away from the
reach of children or pets. These chemicals must be
kept in the original container with the label intact.
• Be aware that not all organic herbicides are “safe”.
Read labels carefully. If you are unsure, research
the product or use a product you are familiar with.
USE HERBICIDES SAFELY
In the pesticide industry, the definition of “exposure”
means getting a pesticide or herbicide on the skin or in
the body.
How serious the hazard is depends on two things:
1. The length of exposure (how long the chemical
is left on the body)
2. The toxicity of the chemical.
An examination of the Signal Words show that there are
various degrees of toxicity.
The Four “Exposure” Contact Points
1. Dermal exposure (Getting chemicals on the skin)
• In chemical exposure, typically 95% of exposure
will occur on the skin. Some areas of the body are
more absorptive than others. The most absorptive
skin on the body is around the genital area. If
you have to take a restroom break while applying
chemical or when mixing, be sure to wash your
hands thoroughly with soap and water first.
Other areas of the body that are highly absorptive
is the scalp, forehead and ears. Be aware of any
cuts or abrasions on the skin that could come in
contact with any chemical.
2. Inhalation Exposure
(Breathing in chemical vapor or dust)
• Inhalation exposure is most likely to occur in
poorly ventilated areas or from breathing in
overspray. If inside, open windows to create air
circulation. Do not turn on the central air or fumes
could be transported to other rooms. If outside, be
aware of wind conditions. The wind can catch the
chemical and blow it into your face.
3. Ocular Exposure
(Chemicals entering through the eye)
• The eyes will easily absorb certain chemicals and
should be protected. Ocular exposure is most likely
to occur from a splash during mixing or from spray
being blown into the face. Wear goggles or a face
shield to prevent this from happening.
4. Oral Exposure (By swallowing)
• Oral exposure most often occurs when residue is
passed from the hands to food being consumed. It
can also occur while taking a smoke break. Be sure
to wash your hands with soap and water before
handling a cigarette or eating.

142649 - OnePass Applicator (28-September-2020)
Overview
The Degelman OnePass chemical applicator
for rotary cutters is designed to efficiently apply
herbicide while mowing. Many of the features
incorporated into this machine are the result of
suggestions made by customers like you.
It is the owner’s or operator’s responsibility
to read this manual carefully to learn how to
operate the machine safely and how to set it to
provide maximum efficiency. Safety is everyone’s
business. By following safe operating practices, a
safe environment is provided for the operator and
bystanders.
Following the operating instructions in conjunction
with a good maintenance program will help
provide your machine with many years of
trouble-free service.
TO THE NEW OPERATOR OR OWNER
The OnePass system reduces operating costs by
mowing and applying herbicide simultaneously.
A unique delivery system allows you to apply
herbicide in sensitive areas without running the risk of
airborne drift or contamination. Instead, herbicide is
delivered from a hermetically sealed fluid reservoir,
via centrifugal force, through the blade bolt to the
underside of the blade. It provides a more efficient use
of time and resources since grass is cut and weeds are
killed at the source in OnePass.
PRINCIPLES OF OPERATION

-6-
142649 - OnePass Applicator (28-September-2020)
Preparation
The application rate to be input into the Raven
console is in ounces per acre (oz/acre).
• For tall, dense vegetation: Best results are achieved
by mixing herbicides to apply at rates of 2 gal/acre
(256 oz/acre) or more, but the tank volume will get
used up faster.
• For short, sparse vegetation: Chemical can be
mixed & applied at rates as low as 1 gal/acre (128
oz/acre) or more, but with reduced flow there is a
chance that equal delivery to each cutting section is
reduced.
Set Console to desired rate in ounces per acre
(oz/acre) from the chart below:
TYPICAL APPLICATION RATES
100L = 3380 oz = 26.4 gal
(Tank filled right to the bottom of the fill spout)
75L = 2535 oz = 19.8 gal
(Filled to the top of the level indicator decal)
50L = 1690 oz = 13.2 gal
(Half tank approximately)
25L = 845 oz = 6.6 gal
(Quarter tank approximately)
5L = 170 oz = 1.3 gal
(Tank filled to the bottom of the level indicator decal)
NOTE: For Console settings, assume full tank volume is
3200 oz. (actual volume can vary due to how the tank
bulges or caves inward).
TANK VOLUME
To estimate acres per hour :
For a 15 foot Rotary Cutter:
Multiply Speed (mph) X 1.82
- Example: 3mph x 1.82 = 5.46 acres/hr
For a 10 foot Rotary Cutter:
Multiply speed (mph) X 1.21
- Example: 3mph x 1.21 = 3.63 acres/hr

Preparation
For testing, use the following steps for operating the
system while stationary:
• Adjust the valves as desired (make sure at least
one input & output valve is open)
• Press "SELF TEST" on the console & enter a
desired speed (usually between 2 & 10 MPH)
• Set console to desired rate, ensure boom switches
are on & turn on master switch.
The pump should run & liquid should be flowing at
the desired rate.
NOTE: If the speed keeps changing to zero
unexpectedly after you have entered in a self
test speed, unplug the Radar or GPS speed input
cable at the console. (If this is not unplugged, any
vibration or grass movement under the tractor will
keep zeroing the speed).
OPERATING THE SYSTEM WHILE STATIONARY
When mixing the chemical with water:
• First, fill the tanks with water to at least half the
desired level.
• Add the calculated and measured amount of
chemical to the tanks.
• Continue to fill the tanks with additional water to
the desired level.
NOTE: Do not add unmixed chemical to the tank
first, or it may not mix properly. When the machine
is operating there is sufficient vibration occurring to
keep the chemical mixed.
MIXING CHEMICALS
Find the application rate for the particular herbicide
on the product label, box or instruction sheet.
NOTE: One way to determine the mix ratio is to
divide the chemical application rate (from label) by
the total application rate (determined by user).
This gives you the percentage of chemical to mix
into a desired volume of water.
Example Mixing Chemical:
1. Product suggested application rate:
0.25L/ha = 101.2 ml/acre
(If application rate on label is in L/ha multiply by
404.8 to get ml/acre) Reference: 1 ha = 2.47 acres
2. Desired application rate setting:
1.5 gal/acre = 5680 ml/acre
(From chart on previous page)
Note: This is the total volume per acre of chemical
after mixing with water.
3. Mix Ratio:
101.2 ml/acre ÷ 5680 ml/acre = 0.01782
(chemical rate from label) (desired application rate)
4. Multiply the mix ratio above with the volume
you plan to fill the tank to:
Full tank: 100L x 0.01782 = 1.782 litres of
chemical added to tank, then fill to
top with water.
3/4 tank: 75L x 0.01782 = 1.337 litres of
chemical added to tank, then fill to
75L mark with water.
1/2 tank: 50L x 0.01782 = 0.891 litres of
chemical added to tank, then fill to
50L mark with water.
1/4 tank: 25L x 0.01782 = 0.446 litres of
chemical added to tank, then fill to
25L mark with water.
NOTE: For chemicals like Tordon 101 at 3.7L/ha, you could
apply at 2 ½ or 3 gal/acre to dilute it more with water, but
the actual volume of chemical per acre is still the same.
NOTE: User preference & knowledge of the product & how
it works with particular vegetation in a region, plus past
experience is key to know how to mix the chemical & at
what rate it should be applied.
CALCULATING MIXING RATES
IMPORTANT:Ensure you have read the
herbicide safety information and followed the
product recommendations for required PPE
during handling/preparation.

Preparation

-9-
142649 - OnePass Applicator (28-September-2020)
IMPORTANT:When ready to apply liquid,
make sure that the valves on the OnePass are in the
desired position.
NOTE: REMEMBER to reset the acres, distance &
volumes if required for personal data records. Also
be sure to either enter the actual volume of product
that is in the tank. If one tank is filled, then set to
3200 oz & if both tanks are filled right up with
product then set to 6400 oz.
• Ensure all the desired boom switches are in the on
position. Make sure the master switch is in the
off position until the cutter is in motion.
• Lower & engage the PTO to begin cutting. The
user can turn the master switch on at any time &
the Raven console will display the speed, vol/min,
distance or rate, depending on what the operator
wants to see.
• IMPORTANT: When in operation, if the cutter
is brought to a stop for any reason, such as a
passing vehicle, the pump will stop applying
liquid & will not restart when the cutter goes
back into motion. The master switch has to be
turned off while stopped (A warning alarm should
show up on the console when this happens). After
resuming motion the master switch can be turned
back on and the pumps will operate again.
• Driving at one constant speed is not necessary.
The Raven console will adjust the speed of the
pump so that the correct rate is being applied at
any given speed. Speed is picked up by either
ground radar or GPS.

Service & Maintenance
IMPORTANT:The CHEMWASH TANK must only
be filled with fresh water for rinsing the system.
NOTE: It is a good idea to keep the outlet valve from
the Chemwash tank in the OFF position to avoid
possible contamination from the rest of the system.
TO RINSE
1. Turn the outlet valve on the underside of the
Chemwash tank to ON, turn the valves on the
Product tanks off. In that position, the suction
will come from the Chemwash tank only. Run the
system as desired to flush out the delivery system.
2. Reverse procedure to return to application mode
& the system is ready to operate or store.
LONG TERM STORAGE OR NON-USE
1. If long term storage or non-use is planned, take
extra steps to clean out & preserve the system.
NOTE: Cold or Freezing conditions, add
plumbing or RV antifreeze to all tanks & run the
system in rinse & in application positions until it is
obvious that antifreeze has filled the entire system.
2. Remove the OnePass product delivery blade
bolts, #500564 & replace with standard blade
bolts, #117415.2.
3. Reverse procedure to return to application mode
& the system is ready to operate or store.

REPOSITIONING SEAL MOUNT
The following are instructions for repositioning the
"Seal Mount" on the blade mount assembly after
changing a gearbox or also if only replacing the
seals, (if only replacing seals, start at Step 4).
Ensure all gearbox/fluid transfer bolts are
positioned, installed and torqued properly before
installing the blade mount assembly.
3. Positioning Seal Mount:
• Position the seal mount centering jig as shown.
(part reference #501824 )
• The seal mount should be bottomed out on the
mower deck tube with the set screws lined up
with the grooves on the deck tube.
• The center should be a snug fit to the gearbox.
• Once centered tighten all 3 set screws evenly
while continuing to check that the Seal Mount is
centered and that the set screws remain in the
grooves.
• Torque setscrews to 80 ft-lb (110 Nm).
• Remove centering jig.
1. Gearbox Installation:
• Install new gearbox with the input shaft in the
correct orientation to the driveline.
• Install the gearbox fluid transfer bolt in the same
hole as previously located.
• Torque gearbox bolts evenly to 400 ft-lb (540 Nm).

2. Loosen 3 Setscrews (not remove):
• Do not remove but loosen the 3 set screws that
hold the "Seal Mount Assembly" to the "Round
Tube" on the underside of the deck.
NOTE: If the seal mount assembly was removed,
then remove most of the caulking & apply new
silicone caulking to the same location on the
seal mount.

4. Clean & Install New Seal:
• If you are replacing
an existing seal, start
by removing the blade
mount & 6 bolts on
the seal retainer plate.
• Remove existing seal, clean surface & install a
new seal if existing seal is worn or damaged.
• Install new Seal with the "O-ring" & the "Coil
Spring" to the inside as shown below. Take
care not to twist or damage the seal.

5. Install the Seal Retainer Plate:
• Install the seal retainer plate with the six
bolts & nuts to hold in place as shown, but
Do Not Tighten Bolts at this stage.
• Smear a thin film of grease onto the seal lip to
aid in installing the "Blade Mount".
6. Install Outer Seal Ring:
• Some versions have an "Outer Seal Ring" that
needs to be installed before the blade mount is
installed on the cutter.
• Install the outer seal onto the blade mount
by hand or by using a pry bar with rounded
edges, as not to cause damage.
• Slide down until the bottom of the seal is 1/4
inch away from the weld around the blade
mount tube.

Ensure all gearbox/fluid transfer bolts are
positioned, installed and torqued properly
before installing the blade mount assembly.
7. Install the Blade Mount:
• Install the "Blade Mount" by aligning the spline
shaft with the hub. The Blade Mount should slide
most of the way on. Take care not to damage
the seal while installing the blade mount.
• Install and torque the Castle Nut
to 800 ft-lb (1085 Nm).
• Install Cotter Pin.
• The seal is now centered to the blade mount.
• Torque the six bolts on the "Seal Retainer Plate"
to 33 lb-ft to lock the seal in place.

Plate Bolts
8. Position the Outer Seal:
• Slide the "Outer Seal" up until the rubber flange
is at least 1/8 inch past where it first contacts
the "Seal Retainer Plate".
• Spin the blade mount by hand, it should rotate
smooth, without binding & appear centered to
the seal holder as it rotates.

IMPORTANT:Never unplug or plug in any
electrical connectors while the Raven console is
powered up!
The result of this can range from the pump or motor
control not responding, or the pump running at
various rates out of control. Other issues may result
such as CAN (controller area network) going offline.
If no liquid is coming out of the blade mount bolts,
check the following:
1. Check the output hole on the blade mount for
plugging, either with an air or water hose.
• If this appears clear then verify that liquid is
getting to the blade mount. (Next step below).
• If this is not clear then back flush the blade
mount bolts with a pressure washer held a couple
feet away from the head of the bolt. Some
water may flow back through the dust seal or the
opposite blade bolt if it clears.
2. Undo a delivery hose right at the gearbox
delivery bolt. Run the system to see if liquid
comes out.
• If it does, then the problem is after the hose. If
not, then check upstream at the manifold.
• If it appears to be a problem after the hose, then
remove the check valve & fittings from the gearbox
delivery bolt & verify they are not plugged.
3. Remove the blades & blade mount from the cutter
& check inside for debris. If debris is present, then
the seal may be worn or damaged. Replace seal.
