Attaching to Power Unit
Note: When you ordered your BrushHound product,
details about your Power Unit were provided to
custom match your Aachment to your Power Unit.
While BrushHound products can be aached to a
variety of dierent skid steers and track loaders,
your Aachment is specically congured for your
Power Unit and can not necessarily be placed on
another Power Unit as is. Specically, the hydraulic
motor and pulleys were selected to opmize
performance based on your hydraulic system. Your
Aachment should only be connected to Power Units
that share the same specicaons as the
informaon on the Power Unit you provided. To
connect your Aachment to another Power Unit,
contact your nearest BrushHound Dealer.
The person that is aaching your BrushHound
product should be familiar with the aachment and
removal of regular buckets from a skid steer or track
loader and be able to do so safely. Aachment
should be performed on at ground away from
obstrucons. During aachment, keep hands out of
pinch points and away from the blades to avoid
injury and ensure hoses are clear of mounng plate:
1) Line the mount on the Power Unit up with the
Universal Skid Steer Mount on the Aachment.
2) Lower the mount on the Power Unit and lt
forward so it can scoop up under the top lip of
the Aachment’s mounng plate.
3) Slowly move Power Unit forward unl it taps
against the mounng plates, li up slightly to
lock into the lip.
4) Check boom poron of mount to ensure ush
mounng between Power Unit and Aachment.
Once ush, lower the locking mechanism on the
Power Unit making sure it has fully engaged.
5) Connect hydraulic hoses to Power Unit.
Removal
To remove the Aachment from the Power Unit:
1) Find a suitable, at locaon to leave the
Aachment where it will not fall over.
2) Make sure the auxiliary hydraulic circuit is o
and lower the Aachment all the way to the
ground. Both the front and rear of the
Aachment should be resng on the ground.
3) Wait for drum to stop rotang and hydraulic
system to depressurize before approaching
Aachment.
4) Unlock the locking devices on the Power Unit’s
mount.
5) Li arm to remove it from the Aachment.
FHX Mounng

Starting Procedure
The Operator should be properly trained on the use
of your BrushHound Aachment and wearing the
appropriate safety gear. Do not start the Power Unit
unl the Aachment has been checked for proper
assembly and installaon. This includes the
appropriate connecon of the mount and hydraulic
connecons as well as the proper funconing of all
safety devices on both the Power Unit and the
Aachment. Clear the work area of all bystanders
and children:
1) Check that the aachment is in the down
posion and that the blades are not in contact
with ground. Start engine and set throle to idle.
Never engage the auxiliary hydraulic ow with
the motor above idle speed.
2) With the motor at low RPM engage the auxiliary
hydraulic ow.
3) Slowly bring the throle up to maximum ow. If
the Aachment produces excessive noise or
vibraon, disengage the auxiliary hydraulics and
shut down the Power Unit immediately.
Determine the cause of the problem and correct
it before connuing with its operaon.
4) Aachment is ready for operaon.
Shut Down Procedure
1) When work is completed, disengage auxiliary
hydraulics and posion it for storage or transport
(See the “Storage and Transport” secon for
details on proper storage). Shut o Power Unit
and set parking brake. Wait for the Aachment
to stop rotang and allow hydraulic circuits to
bleed back to reservoir, as they can sll be
pressurized even when turned o, before
approaching or allowing others to approach the
Aachment.
2) Visually inspect hydraulic motor, motor
protecon valve and other areas for signs of
excessive heat, debris accumulaon or leaks. Do
not touch these areas with bare skin as they can
be very hot. Hydraulic leaks should never be
checked for with hands as the uid may have
adequate force to puncture the skin which would
require immediate medical aenon and can
lead to gangrene within hours. Instead, if you
believe there is a hydraulic leak, check with a
piece of cardboard or paper.

O Ground & Level
FHX Series by
FHX Starng Posion

Basic Operation
Running Your Attachment
1) Level sides of the Aachment with the ground,
making sure skid shoes are just above ground
level. Skid shoes are designed to collide with
uneven surfaces, not run along the ground.
2) Ground speed should range anywhere from 0-5
miles per hour. However, the operator should
drive at a speed they are comfortable with given
terrain and brush density.
3) Small trees can be driven into and knocked over
with the push bar, allowing the Aachment to
connue running along the ground. For larger
trees, raise the Aachment into the air, making
sure it is oriented such that the blades are not
visible. Then clip o the upper part of the tree
and slowly lower the aachment, mulching the
remaining tree to the ground.
Note: Be reasonable in which trees you aempt to
mulch, excessively large and tall trees could fall on or
knock over your Power Unit.
Basic Guidelines
1) Your Aachment is most ecient when the
knives are sharp and turning at full RPM. Your
specic recommended sha speed is listed on
the unit’s Serial Number plate, but it should
range from 1700-2200 RPM.
2) Before beginning your job, walk the work area
and clear all the hidden hazards such as large
rocks, ulity lines, fencing and hidden debris like
broken glass, boles and miscellaneous
materials. Projected debris can cause injuries to
operators, pedestrians, livestock or damage
property.
3) While inspecng the work area, be on the
lookout for bees, re ants, poison ivy or poison
oak. Also be aware of improper working
condions such as overly saturated grounds
which can cause slippery condions. Taking note
of all potenal area hazards will increase your
producvity as well as your safety.
4) Never allow bystanders to be near mowing or
brush cung or to climb on the machine.
5) Loading or “lugging down” the cuer excessively
will signicantly reduce its cung capacity and
result in increased hydraulic oil temperature.
Stay aware of the cuer drum speed and li out
of the cut unl maximum speed is regained
before resuming.
6) Do not use this aachment as a bucket to dig up
roots and spread piles of dirt. This type of
damage will not be covered by your warranty
and repairs will be expensive. The weldment’s
design is strong enough to last for decades if
cared for properly.
7) Never start the aachment if the safety guards
are not securely fastened to the aachment.
8) Abuse can be indicated by drum damage or
premature knife failure. To prevent abuse,
always reduce cung load before signicant
cuer drum speed is lost.

Adjustments & Maintenance
ATTENTION
Review all safety informaon outlined in
safety secon of manual before proceeding
with any adjustments or maintenance.
Lubrication
The FHX Series has 3 lubricaon points,
idenable by the presence of a grease ng.
Use only BrushHound approved grease or a
compable grease with similar specicaons and
EP addives. For all 3 of the FHX’s grease points
BrushHound recommends using Mobilith SHC
100 Grease. Over-greasing seals and bearings
can cause damage, if grease purges from the
bearings’ seals too much grease has been
applied. If the purged grease is black and smells
burnt, this may be a sign of chronic over-
greasing.
a)Cuer Drum Bearings
On each end of the cuer drum, behind the bolt
on covers are the cuer drum bearings. These
are double row spherical bearings with high
speed Teon seals, each comes with a grease
ng and prepacked with high quality grease
from the factory. Greasing intervals are
dependent on condions, but for standard use
the main bearings require 10 pumps of grease
from a manual grease gun every 60-80 hours of
operaon. Abnormally wet condions, where
bearings are connuously moist, may require
more greasing.
b) Overhung Load Adapter
In the motor compartment, mounng the motor
to the side wall is the overhung load adapter. It
has a grease line that runs to the top of the FHX
and comes prepacked with high quality grease
from the factory as well. The grease interval for
the overhung load adapter is 10 pumps every
300 hours, or every fourth cuer drum bearing
greasing.
Wearable Component
Maintenance
a) Rubber Drive Belt
The drive belt is located behind the pulley
housing cover on the drive side of the
aachment. The belt itself has a lifeme of
over 1000 hours, but should be inspected
regularly for excessive wear. If the belt
appears worn thin or torn it should be
replaced. It should also be replaced
whenever the cuer drum is removed.
• Drive Belt Tension - Drive belt tension
can be achieved by rst removing the
drive side pulley cover and the motor
guard cover. With the covers removed
you will gain access to the overhung load
adapter mounng plate. The over hung
load adapter mounng plate has bolts
that when ghtened pull the enre
assembly toward the mounng plate,
pung tension on the drive belt.
b) Hydraulic Hoses
The hydraulic hoses located within the motor
guards have been placed to minimize their wear
caused by rubbing against metal surfaces.
However, due to heavy vibraon their posions
can shi so regular inspecon for excessive wear
should be performed.
c) Bearings
Bearing failure can be indicated by excessive
vibraon or noise or the complete seizing of the
cuer drum altogether. Imminent bearing failure
signs can be more subtle and go unnoced
without appropriate diagnosc equipment. As a
precauon, bearings should be replaced every
1500-2000 hours of operaon depending on the
environment and usage condions.
d) Safety Guards
Safety guards are in place for the protecon of
the Operator, bystanders and nearby property
and should never be removed for operaon.
Therefore, it is important that each safety guard
13 www.brushhound.com

14
FHX Series by
is capable of performing its guarding funcon. Any
worn guards or guards with rust penetrang deep
enough to compromise their strength should be
replaced. To prolong the guards life, regularly clean
the guards and keep them painted as this provides
protecon from the elements.
• Cuer Drum Door - Cuer drum door can be raised
or lowered by using the adjustable top link Ratchet.
At no point should the Aachment be run without
the
Cuer Drum Door.
e) Safety Decals
Safety decals are not cosmec, they are in place to
warn the Operator and bystanders of the dangers
inherent of this machine. Safety decals should
always be clearly legible, even from a distance, and
should never be covered for any reason. Faded or
worn decals should be replaced.

Adjustments & Maintenance
Knife Maintenance
Since the FHX Series is designed for Forestry
Mulching, it is crical that the knives are present
and that they be kept sharp to keep cung
eciency at a maximum. The standard cung tool is
a hardened steel knife with mulple cung
surfaces, allowing it to be either sharpened, rotated,
or replaced depending on the circumstances (on
certain models an upgraded mul-surface carbide
blade is oered that can be rotated or replaced).
1)Rotang
The standard knife oered has 4 cung surfaces,
allowing for up to 3 rotaons in the eld where
replacements or sharpening equipment may not
be available. To rotate the knife, loosen the
retenon bolt and; First rotaon 180°, Second
Rotaon 90°, and third rotaon at 180°. Reghten
to 2000 -lbs with a grade 8 bolt. You will noce
that the limiter on the knife holder does not allow
the sharp corner to be centered, this is intenonal
as it is the U-shaped surface that is the cung
poron not the edge.
2)Sharpening
When sharpening tools are available, the knives
can be sharpened in the holder using a grinder.
Simply run the grinder in plane with the at V-
shaped side, surfacing the outer edge of the knife.
3)Replacing
