Operation
TRACTOR PREPARATION
1. Wheel Spacing
Important: To avoid possible damage from
over stressing tractor axles, use no tire combination
which results in overall width greater than the
width of the angle blade.
Important: Before beginning operation, turn
the wheel fully to the right and left to be sure there
is sufficient clearance between the tires and the
angling cylinders. If necessary, move the wheels
to a wider setting to provide clearance. See your
Tractor Operator's Manual.
2. Rear Wheel Weight and Tire Inflation:
Add necessary rear end weights for efficient
operation and safety. Any of the cast-iron weights
recommended for your tractor or liquid in the tires,
may be used for necessary ballast. Be sure the
weight is distributed equally on each rear wheel.
Inflate front and rear tires to proper pressure as
recommended in the Tractor Operator’s Manual for
heavy front-mounted implements.
3. Checking Hydraulic Oil Level:
Check the oil level in the tractor hydraulic system
daily. Refer to your tractor operator's Manual for
Instructions. Keep the oil supply up to the proper
level. Before checking oil supply, fully extend
and retract angle and lift cylinders 3 - 4 times and
return the blade to the ground.
ATTACHING THE DOZER BLADE
NOTE: Please refer to the assembly section of this
manual - for full instructions for attaching your
specific tractor and blade model.
BLEEDING THE HYDRAULICS
Before beginning operation, bleed the hydraulic
system to remove any air. To do this, cycle the
hydraulics several times by holding the cylinder
fully extended for several seconds. This will cause
any trapped air to be purged from cylinder.
COLD WEATHER OPERATION
To assure smooth operation in cold weather, cycle
the cylinders several times to warm the oil in the
hydraulic system.
TO THE NEW OPERATOR OR OWNER
The Degelman Dozer Blade is a push type tractor
attachment designed primarily for excavating,
levelling and filling of dirt, snow and silage.
It is the owners or operators 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.
The manual will take you step-by-step through
your working day. By following the operating
instructions in conjunction with a good
maintenance program your machine will provide
many years of trouble-free service.
BREAK-IN
Although there are no operational restrictions on
the Dozer Blade when it is new, there are some
mechanical checks that must be done to ensure
the long term integrity of the unit. When using the
machine for the first time, follow this procedure:
A. Before using:
1. Read Operator's Manual.
2. Lubricate all points shown in the
Maintenance Section.
3. Check all bolt tightness.
B. After operating for 2 hours:
1. Check all hardware.
2. Check all hardware tightness.
3. Check all hydraulic system connections.
Tighten if any are leaking.
C. After operating 10 hours:
1. Repeat Step B.
2. Go to the service schedule as outlined in the
Maintenance Section.
PRINCIPLES OF OPERATION
The dozer blade consists of a blade/cutting edge
unit attached to a pivot-main frame combination
suspended from the tractor by the front and side
mount brackets. By driving the tractor forward
with the blade either straight ahead or angled,
and allowing the cutting edge to run just under the
ground surface - dirt, silage or snow is relocated
as desired.

-5-
143351 - 69/7200 Series (12-May-2017)
Operation
ANGLING DOZER BLADE
The dozer blade can be hydraulically angled
approximately 30° to the right or left by operating
the proper tractor remote cylinder lever. In the
angled position, the dozer blade can be used
for backfilling trenches, side-casting into ditches,
levelling and grading.
A dual relief valve is incorporated to protect
the hydraulic angling system when the blade is
overloaded. (This valve will bypass the hydraulic
fluid and diminish the degrees that the blade was
initially angled.)
Important: To avoid damage to tractor or
blade, the hydraulic system must be hooked up
properly including line to hydraulic tank drain.
FLOATING THE DOZER BLADE
Here are some the things you can do with your
hydraulic system in float position:
• Skim the top of pavement
• Run on the skid shoes
• Back drag
By placing the remote cylinder operating lever for
the lift function in float position, the blade may be
used to smooth an area by running the tractor in
reverse (refer to Tractor Operator's Manual). On
moderate grades, the tractor can be driven up
the slope and the blade dropped down for back-
dragging. It may also be used to push dirt or snow
on pavement or other smooth surfaces.
OPERATOR’S RESPONSIBILITY
Every operator should read this manual and
be instructed in safe operating procedures. An
untrained operator is not qualified to operate this
machine and could place themselves or bystanders
in danger.
OPERATING SPEED
For normal operation, operate the tractor at a
comfortable or manufacturer recommended speed.
When operating over rough terrain or limited to
space, reduce engine speed. The actual forward
speed will be determined by tractor horsepower,
land density and depth of cut.
Experience will teach you the most efficient operating
speed, but as a rule 3-4 MPH (5-7 km/h) is a normal
operating range.

BLADE DEPTH
Gauge the depth of cut to push the most material
possible without losing speed through spinning
the wheels or slowing the tractor engine. Do this
by setting the depth shoes, and by regulating the
depth for the blade height with the lifting cylinder
operating lever.
The distance the material is pushed should be kept
to a minimum. Dig and cut the material downgrade
whenever possible.
PRE-OPERATION CHECKLIST
Efficient and safe operation of the Dozer Blade
requires that each operator reads and understands
the operating procedures and all related safety
procedures outlined in this manual.
Before Using for the FIRST Time
• Lubricate all points
• Torque all hardware to correct setting
• Check hardware torque & hydraulics
after the first 2 hrs & again after 10 hrs.

HYDRAULIC SAFETY
1. Always place all tractor hydraulic controls in
neutral before dismounting.
2. Make sure that all components in the hydraulic
system are kept in good condition and are clean.
3. Replace any worn, cut, abraded, flattened or
crimped hoses and metal lines.
4. Do not attempt any makeshift repairs to the
hydraulic lines, fittings or hoses by using tape,
clamps or cement. The hydraulic system operates
under extremely high pressure. Such repairs will
fail suddenly and create a hazardous and unsafe
condition.
5. Wear proper hand and eye protection when
searching for a high pressure hydraulic leak. Use a
piece of wood or cardboard as a backstop instead
of hands to isolate and identify a leak.
6. If injured by a concentrated high-pressure stream of
hydraulic fluid, seek medical attention immediately.
Serious infection or toxic reaction can develop from
hydraulic fluid piercing the skin surface.
7. Before applying pressure to the system, make sure
all components are tight and that lines, hoses and
couplings are not damaged.
Think SAFETY! Work SAFELY!

TRANSPORTING
Follow this procedure when preparing to transport:
1. Clear the area of bystanders, especially small
children, before converting into transport
configuration.
2. Operate the lift hydraulics to raise the blade fully
and install a certified safety chain to secure it.
3. Clean the SMV sign, lights and reflectors.
4. Maintain a safe speed. Slow down when
cornering and on rough roads.
5. Slow down and pull off to the side of the road
when meeting other traffic.
6. Use hazard flashers on tractor unless prohibited
by law.
Transport & Storage
TRANSPORT SAFETY
• Read and understand ALL the information in the
Operator's Manual regarding procedures and
SAFETY when operating the machine in the field/
yard or on the road.
• Check with local authorities regarding machine
transport on public roads. Obey all applicable
laws and regulations.
• Always travel at a safe speed. Use caution when
making corners or meeting traffic.
• Make sure the SMV (Slow Moving Vehicle)
emblem and all the lights and reflectors that are
required by the local highway and transport
authorities are in place, are clean and can be
seen clearly by all overtaking and oncoming
traffic.
• Keep to the right and yield the right-of-way to
allow faster traffic to pass. Drive on the shoulder,
if permitted by law.
• Always use hazard warning flashers on tractor
when transporting, unless prohibited by law.
STORAGE
After the season's use, completely inspect all major
systems of the machine. Repair or replace any worn
or damaged components to prevent unnecessary
down time at the beginning of next season.
Since the unit can be used in extremely adverse
conditions during the season, the machine should be
carefully prepared for storage to ensure that all dirt,
mud, debris and moisture has been removed.
Follow this procedure when preparing to store:
1. Wash the entire machine thoroughly using a water
hose or pressure washer to remove all dirt, mud,
debris or residue.
2. Inspect all parts to see if anything has become
entangled in them. Remove the entangled
material.
3. Lubricate all grease fittings to remove any
moisture.
4. Inspect all hydraulic hoses, fittings, lines and
couplers. Tighten any loose fittings. Replace any
hose that is badly cut, nicked or abraded or is
separating from the crimped end of the fitting.
5. Touch up all paint nicks and scratches to prevent
rusting.
6. Oil the exposed rams on the hydraulic cylinder to
prevent rusting.
7. Select an area that is dry, level and free of debris.
STORAGE SAFETY
•Store unit in an area away from human activity.
•Do not permit children to play near the stored unit.

Troubleshooting
GENERAL TROUBLESHOOTING
SYMPTOM PROBLEM SOLUTION
Blade falls down in
transport.
Lift cylinder hydraulic circuit not connected
correctly.
Trace your hoses from front to back of tractor, making sure angle
circuit connected to rear relief valve, not lift circuit.
Blade angle won’t
hold.
Excessive loading of dozer. Reduce amount of material pushing. Equipped with safety angle
relief valve, pressure exceeded.
Excessive impact on dozer. Reduce speed of impact on high load. Equipped with safety angle
relief valve, pressure exceeded.
Cutting edge wearing
excessively in center
of the blade.
High downward force of dozer in contact
with crown of road.
Adjust skid shoes to prevent cutting edge contact with road
crown.
Change operation of the dozer to prevent running on crown of
road.
Cutting edge wearing
excessively at ends of
the blade.
High downward force on ends of dozer. Run dozer tilt circuit (7200-models) in float to contour to ground.
Change operation to prevent this type of contact.
Adjust skid shoes to prevent contact.
Hydraulic angle circuit
hoses pop out of valve
stack.
Relief valve tank drain hose not connected
properly.
Ensure hydraulic tank drain hose goes directly to tank with no
internal pressure.
Breaking cutting
edge bolts.
Cutting edge bolts not properly torqued. Under torqued bolts allows impact to break bolts.
Over torqued bolts can fail from too much tension loading.
Torque 5/8” GR8 bolts to 225 lb-ft
Torque 3/4” GR8 bolts to 400 lb-ft
Blade won’t angle or
will not come back
from full angle.
Hoses not properly coupled in valve stack. Remove and re-install hoses into valve stack.
Angle relief valve return to tank line not
properly installed.
Change return to tank line so that no internal pressure, run direct
to tank.
Blade not following
ground contour.
Tilt circuit (7200-models) not allowed to
float.
Float hydraulic tilt circuit.
Cannot align front
bracket roller with
main frame front
quick attach lug.
Heights are not aligned. Use dozer hydraulic lift circuit to adjust main frame front lug
height.
Use jacks on side on main frame to adjust height.
Cannot Retract HQT
Cylinder Pins when
attached to tractor.
Blade not raised off the ground. Lift blade off ground. (Raising the blade off the ground removes
pressure from the HQT - ”Hydraulic Quick-Tach” pins.)
*Ball Valve not open. Open Ball Valve.
