Description of Unit
Utilizing many of the rugged and reliable features of the
original Pulvi-Mulcher, these units are still performing
seedbed finishing operations in fields all over the world.
The lower horsepower requirements and smaller size fit
into many specialty niche markets such as nurseries and
landscape operations and equine training facilities.
Choice of notched or crowfoot wheels allow these
machines to be set-up to match your soil conditions.
Using this Manual
This manual will familiarize you with safety, assembly,
operation, adjustment, and maintenance. Read this
manual and follow the recommendations to help ensure
safe and efficient operation.
• The information in this manual is current at time of
printing. Some parts may have changed to assure top
performance.
• Location reference: Right and Left designations in this
manual are determined by facing the direction the
implement will travel during field operation, unless
otherwise stated.

INTRODUCTION AND SAFETY INFORMATION
Safety
NOTE
Investigation has shown that nearly 1/3 of all farm
accidents are caused by careless use of machinery.
Insist that all people working with you or for you abide by
all safety instructions.
Understanding Safety Statements
You will find various types of safety information on the
following pages and on the implement decals (signs)
attached to the implement. This section explains their
meaning.
NOTICE


WARNING

DANGER
NOTE
You should read and understand the information
contained in this manual and on the implement decals
before you attempt to operate or maintain this equipment.
Examine safety decals and be sure you have the correct
safety decals for the implement. See Figure 1-3.
Order replacement decals through your Brillion dealer.
Keep these signs clean so they can be observed readily.
It is important to keep these decals cleaned more
frequently than the implement. Wash with soap and water
or a cleaning solution as required.
Replace decals that become damaged or lost. Also, be
sure that any new implement components installed
during repair include decals which are assigned to them
by the manufacturer.
When applying decals to the implement, be sure to clean
the surface to remove any dirt or residue. Where
possible, sign placement should protect the sign from
abrasion, damage, or obstruction from mud, dirt, oil etc.

DANGER
Transporting Safety
IMPORTANT
It is the responsibility of the owner/operator to
comply with all state and local laws.
When transporting the implement on a road or highway,
use adequate warning symbols, reflectors, lights and
slow moving vehicle sign as required. Slow moving
tractors and towed implements can create a hazard when
driven on public roads. They are difficult to see,
especially at night.
Do not tow an implement that, when fully loaded, weighs
more than 1.5 times the weight of the towing vehicle.
Carry reflectors or flags to mark the tractor and
implement in case of breakdown on the road.
Do not transport at speeds over 20 MPH under good
conditions. Never travel at a speed which does not allow
adequate control of steering and stopping. Reduce
speed if towed load is not equipped with brakes.
Avoid sudden stops or turns because the weight of the
implement may cause the operator to lose control of the
tractor. Use a tractor heavier than the implement.
Use caution when towing behind articulated steering
tractors; fast or sharp turns may cause the implement to
shift sideways.
Keep clear of overhead power lines and other
obstructions when transporting. Know the transport
height and width of your implement.
Attaching, Detaching and Storage
• Do not stand between the tractor and implement when
attaching or detaching implement unless both are
blocked from moving.
• Block implement so it will not roll when unhitched from
the tractor.
Special notice - read and thoroughly understand.
Proceed with caution. Failure to heed caution
may cause injury to person or damage product.
Proceed with caution. Failure to heed warning will
cause injury to person or damage product.
Proceed with extreme caution. Failure to heed
notice will cause injury or death to person and/or
damage product.
• Do not allow anyone to ride on the tractor or
implement. Riders could be struck by foreign
objects or thrown from the implement.
• Never allow children to operate equipment.
• Keep bystanders away from implement during
operation.

INTRODUCTION AND SAFETY INFORMATION
2K795 1-3
Maintenance Safety
• Block the implement so it will not roll when working on
or under it to prevent injury.
• Do not make adjustments or lubricate the machine
while it is in motion.
• Make sure all moving parts have stopped.
• Understand the procedure before doing the work. Use
proper tools and equipment.
Protective Equipment
• Wear protective clothing & equipment appropriate for
the job. Avoid loose fitting clothing.
• Because prolonged exposure to loud noise can cause
hearing impairment or hearing loss, wear suitable
hearing protection, such as earmuffs or earplugs.
Tire Safety
Tire changing can be dangerous and should be
performed by trained personnel using correct tools and
equipment.
When inflating tires, use a clip-on chuck and extension
hose long enough to allow you to stand to one side, not in
front of or over the tire assembly. Use a safety cage if
available.
When removing and installing wheels use
wheel-handling equipment adequate for the weight
involved.
Chemical Safety
Agricultural chemicals can be dangerous. Improper use
can seriously injure persons, animals, plants, soil &
property.
Read chemical manufacture’s instructions and store or
dispose of unused chemicals as specified. Handle
chemicals with care & avoid inhaling smoke from any
type of chemical fire.
Store or dispose of unused chemicals as specified by the
chemical manufacturer.
Prepare for Emergencies
• Keep a First Aid Kit and Fire Extinguisher handy
• Keep emergency numbers for doctor, ambulance,
hospital and fire department near phone.
High Pressure Fluid Safety
Escaping fluid under pressure can be nearly invisible and
have enough force to penetrate the skin causing serious
injury. Use a piece of cardboard, rather than hands, to
search for suspected leaks.
Any fluid injected into the skin must be surgically
removed within a few hours or gangrene may result.
Avoid the hazard by relieving pressure before
disconnecting hydraulic lines.
NOTE
Relieve hydraulic pressure by shifting the control valve
lever to float.
Wear protective gloves and safety glasses or goggles
when working with hydraulic systems.

INTRODUCTION AND SAFETY INFORMATION
Safety Chain
Use a safety chain to help control drawn machinery
should it separate from the tractor drawbar.
Use a chain with a strength rating equal to or greater than
the gross weight of towed machinery, in accordance with
ASAE S338.2 specifications. If two or more machines are
pulled in tandem, a larger chain may be required. Chain
capacity must be greater that the total weight of all towed
implements.
A second chain should be used between each
implement.
Attach the chain to the tractor drawbar support or
specified anchor location. Never attach the chain to an
intermediate support. Allow only enough slack in the
chain to permit turning. The distance from hitch pin to
attachment point or intermediate support point should not
exceed 9 inches. If the distance from the drawbar pin to
either the front or rear chain attachment point exceeds 9
inches, intermediate chain support is required.
Replace chain if any links or end fittings are broken,
stretched or damaged.
Do not use a safety chain for towing.

Tire Installation

WARNING
NOTE
All tire/wheel assemblies are mounted with the valve
stem facing outward from Hub and Spindle.
Install the tire and wheel assembly onto the hub with
1/2-20 X 1 Wheel Bolts and tighten to 65 ft-lbs. See
Figures 2-4 and 2-5. The M881 Pulvi-Mulcher uses 7.60
x 15 6 ply tires. Inflate all tires equally to avoid side draft.
Follow the tire manufacturer’s recommended pressures
listed on the sidewall of the tires.
Figure 2-4: Stud Tightening Sequence
NOTE
Torque will drop after the first 10 hours of operation.
Check the nuts for proper torque after this interval and
retighten them.

Plate tubes. Insert the 3/4-10 x 10 Bolt through the
Spring Guide and Drawbar Anchor Plate and screw it into
the yoke. Join the Yoke and the 2 x 36-1/4 Straps with a
2-1/2 x 7-1/4 Strap and 3/4 x 1-7/8 Clevis Pins, secure
with 5/32 x 1-1/2 Cotter Pins. See Figure 2-7.
When making the final connection, the drawbar may
need to be blocked up a few inches for easier assembly.
Turn the 3/4-10 x 10 Bolt into or out of the yoke to level
the Pulvi-Mulcher.
For tractors with low drawbars, turn the bolt out of the
yoke so that the bolt is just through the yoke.
For tractors with higher drawbars, turn the bolt further
into the yoke.
Most of the Bolt threads will be used when the tractor
drawbar is 20 inches or more above the ground.

Hydraulics Installation

WARNING

CAUTION
Install Elbow Fitting O-Ring end into the Cylinder Ports
and attach hoses. Run the hoses down the drawbar
through the hose support towards the tractor.
See Figure 2-10.
Turn an Adapter Fitting O-Ring end into each Coupler.
Install Adapter into the end of each hose.
Secure hoses with tie straps.
Hook tractor to implement and disengage the Transport
Lock. Charge the Hydraulic System.
Tightening Procedure For JIC 37° Swivel Female
Nuts
1. Check flare and seat for defects.
2. Lubricate the connection.
3. Install hoses without twists.
4. Hand tighten until connection bottoms.
5. Using 2 wrenches to prevent twisting, rotate the
swivel nut 2 wrench flats (1/3 turn).
6. For reassembly, follow the same procedure but
tighten only 1 wrench flat (1/6 turn).
Tightening Procedure For Swivel O-Ring Fittings
1. Lubricate o-ring and install the fitting until the metal
washer which backs up the o-ring contacts the face
of the boss.
2. Orient the fitting by turning counterclockwise up to 1
turn.
3. Tighten the lock nut using 50-60 foot pounds torque.
Purging the Hydraulic System

WARNING
Figure 2-9: Hydraulic Leak Detection
The hydraulic system is not filled with oil and should be
purged of air before transporting and field operations.
Carefully hitch the M881 to the tractor and connect the
hydraulic hoses. Check to make sure the tractor hydraulic
reservoir is full of the manufacturer’s recommended oil.
Bleed the air from the hydraulic system before moving
the machine. Bleed the air from the transport system first.
This can be done by partially raising and lowering the
machine slowly 5 or 6 times. Gradually increase the
length of stroke until the last two cycles are the full stroke
on the cylinder.
Escaping fluid under pressure can be nearly
invisible and have enough force to penetrate the
skin causing serious injury. Use a piece of
cardboard, rather than your hands, to search for
suspected leaks. Wear protective gloves & safety
glasses or goggles when working with hydraulic
systems.
Do not raise the machine without the use of
hydraulics. This would introduce air into the
hydraulic cylinder. When the transport pin is
removed the frame would lower rapidly possibly
causing injury.
Escaping hydraulic fluid can cause serious
personnel injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands. See
Figure 2-9. Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
