and head protection to protect  
the operator from any flying  
debris and noise.  
All personnel except operator should be 150 feet clear of machinery before starting  
or operating it.  
Never use drugs or alcohol before or while  
operating your brush mower.  
Be aware that operating equipment for an extended period of time can result in fa-  
tigue or boredom and may cause the operator to lose awareness of what he/she is  
doing. It is recommended that scheduled work breaks be taken to avoid this.  
Keep hands and loose clothing away from any power-driven parts.  
Avoid contact with hot surfaces including pumps, motors, hydraulic oil tanks and  
hose connections.  
Do not operate this machine without all guards being in good condition and firmly in  
place.  
Do not operate this machine on a excavator that is not properly maintained. If a  
control failure should occur while operating this machine, immediately shut it down  
and perform repairs before continuing.  
Be aware of the cutter drum rotation direction and do not let bystanders stand  
within 150 feet to either side of the mower.  
Under no circumstances should the blades of this attachment contact the ground or  
be curled up to where they are visible to the operator. Serious injury or death can  
occur.  
Always walk the area to be worked to insure the jobsite is free of obstacles and de-  
bris that could injure the operator or damage the machine.

SAFETY (cont.)  
SAFE OPERATION 3  
Stop the operation of this machine when people or vehicle driver’s vision becomes  
obscured, caused by the discharge of materials and dust. Also avoid operating this  
attachment in unusually foggy or dusty conditions or at night.  
Never leave the excavator or the brush shredding attachment unattended while it is  
in the lifted position or while the shredder is spinning.  
Keep away from rotating elements to prevent entanglement.  
Listen for blades to completely stop prior to dismounting  
machine.  
Use flashing warning lights when operating on highways,  
except when prohibited by law.  
If using the side shredding method, drive at a speed you  
can safely operate the vehicle and attachment. Normal  
ground speed ranges from 0-5 miles per hour. Use slow  
speeds when operating on or near slopes, ditches, drop-  
offs, or when debris and foreign objects are to be avoided.  
Use the following guidelines to reduce the risk of equipment  
and grass fires:  
- Do not smoke or have an open flame near the machinery.  
- Do not drive into burning areas or areas that have been freshly burned.  
- Do not mow areas that are tinder dry and can burn easily.  
- DO NOT allow debris to collect near hydraulic motors and gearboxes.  
Do not position the attachment or turn it so sharp that the hoses could get pinched  
or squeezed.

Maintain all safety decals and make sure they are visible to the operator and by-  
standers. If decals are worn, contact your nearest Kubota dealer for replacements.  
Replace bent or broken blades with new ones. Do not attempt to weld or bend  
damaged blades. This can cause cracking or other types of damage that could re-  
sult in the blade being thrown from the brush mower.  
Wear gloves and eye protection and exercise care when handling blades. Also be  
alert to worn or damaged surfaces that could have sharp edges.  
Disengage hydraulics and shut off engine, bleed off hydraulic pressure to both high  
and low flow circuits allowing all movement to stop before leaving the operator’s po-  
sition to adjust, lubricate, clean, unclog, remove or install the attachment. See Ku-  
bota KX080-3 Operators Manual for detailed instructions on bleeding off hydraulic  
pressures.  
Before working on or underneath the attachment, place blocks on both sides (front  
and back) of operating vehicle tires or treads and under each end of the attachment  
to prevent accidental lowering of the machine. Also remove the ignition key from  
the operating vehicle and allow all movement to stop before beginning work.

ATTACHING TO THE EXCAVATOR 5  
ATTACHING TO THE KX080  
ATTENTION  
The K4080 brush mower is designed specifically for the Kubota KX080 excavator  
and should not be used on any other machine. Make sure the person who is attach-  
ing this brush mower has knowledge of attaching regular buckets and can do so in  
a safe manner. The method used most often for attaching this brush mower is the  
“curl-in” method.  
Note: Remember to allow at least 3-5 minutes for the excavator to warm-up before  
using with any oil-operated functions or attachments.  
Move the KX080 into position behind the brush  
mower. Keep in mind that the “back” of the  
mower is the end with the hydraulic motor.

Once the power unit is in position, lower the ex-  
cavator arm into position, inserting the rear por-  
tion of the mount into the Quick-Attach (1) first  
and then “curling” the front portion down into  
place. Insert factory pin (2) to keep brush mower  
locked in place. Refer to photo on left.  
Extend the main excavator dipper to its full length  
in front of the excavator and set mower down with  
the skid shoes firmly on level ground. This will  
allow for easy access to the (3) flat-face couplers.  
Never stand on attachment to reach couplers.  
Turn off the excavator and bleed down pressure  
on both high and low flow hydraulic circuits. See

coupled to the high-flow circuit (26.4 GPM) oper-  
ated by the right-hand joystick in the excavator.  
Then enable hydraulic breaker mode on the ex-  
cavator, allowing for zero pressure return, (4) by  
turning the valve located near the hydraulic reser-  
voir to the return to tank position. This step is  
vital and if not followed will result in damage

ADJUSTMENT & MAINTENANCE 6  
ADJUSTMENT & MAINTENANCE  
CLEANING YOUR BRUSH MOWER  
To preserve life of paint and decals, wash the brush mower after each use. The  
preservation of your brush mower’s decals is essential to safety, so make sure they  
are kept in good condition. It is also recommended that some sort of degreasing  
solution be used on all bearings.  
Check for excessive grease in bearing areas. Clean off any excessive amount.  
Clean clippings from hydraulic hose areas, mounting areas or any areas that may be  
susceptible to excessive heat.  
Clean inside the brush mower with a pressure washer. Make sure the inside of the  
mower is kept free from mud and compact grass. Keep in mind that mud built up on  
the cutter drum can cause imbalance resulting in vibration.  
Preserve damaged decals or replace them if they are unreadable. Decal kits can be  
obtained from your local Kubota dealer.  
Inspect blades for small cracks across the hole and insure they are wearing evenly.  
Inspect attachment hardware such as bolts and roll pins to make sure they are tight.  
Kubota strongly recommends  
dealers order one starter pack of knives to  
be shipped with every K4080 brush mower.

BASIC OPERATION 7  
BASIC OPERATION  
Running Your Attachment  
The K4080 brush mower is designed to cut all types of vegetation such as grass, brush  
and small trees. The condition of your terrain and the material to be cut should be  
evaluated for the best results.  
House Rotation Mowing  
House Rotation Mowing  
Brush on flat terrain can be cut by rotating the house  
control from side-to-side and keeping the cutter head  
just above ground level, moving the excavator for-  
ward 40” at a time into uncut material.  
Side Mowing  
Another technique is to place the cutter head next to  
the machine and drive forward keeping the head  
near the road’s shoulder or edge of what you are cut-  
ting around.  
Side Mowing  
Top Down Mowing  
The last way of operation is to start at the top and  
work toward the ground. Raise the boom all the way  
up and curl it away from you. This will allow the  
head to be inverted and trim tree canopies. Then  
swing the head from side to side in the vertical posi-  
tion to trim the sides of trees. Finally, position the  
head parallel to the ground to completely mulch the  
branches and grass, eliminating any clean-up by  
hand crews.  
Top Down Shredding  
Brush cutting covers a wide range of conditions  
and is more dangerous than mowing because of  
the hidden objects. For this application, be sure  
to feed large diameter branches or thick brush  
into the side of the shredder where the blades  
are hitting down. To reduce discharge, move  
into uncut material with the discharge side of the  
brush mower. This reduces debris throw signifi-  
cantly. Never allow observers within 150’ of the  
brush mowing operation.

BASIC OPERATION 8  
BASIC OPERATION  
1. Before beginning your job, walk the mowing area and clear all hidden hazards such  
as large rocks, stumps, utility lines and hidden debris like broken glass, bottles and  
miscellaneous materials. Projected debris can cause injuries to operators, pedes-  
trians, livestock and property.  
2. While inspecting your work area for debris, be on the lookout for bees, fire ants,  
poison ivy and poison oak. Taking note of potential area hazards will increase your  
productivity as well as your safety. Also avoid improper working conditions such as  
overly saturated grounds, which can cause slippery conditions.  
3. Check your discharge path. Most mowers and brush cutters will have some combi-  
nation of material discharge system. Mulching flail mowers and brush cutters are  
bi-directional. This allows the utilization of both sides of the blades. Always make  
sure you know the discharge direction and discharge flaps are properly secured  
and in good working order. Never start the mower if attachments are not securely  
fastened to the power unit.  
4. Your brush cutter is most efficient when the knives are sharp and turning at full  
RPM. 1500-1800 RPM is the recommended speed the cutter shaft should turn.  
5. Loading or “lugging down” the cutter excessively will reduce its cutting capacity and  
result in increased hydraulic oil temperature. Stay aware of the cutter drum speed  
and lift out of the cut until maximum speed is regained before resuming.  
6. When cutting larger diameter material, lay the tree down with the blade and plane  
the tree from side-to-side. This will result in a finer mulch which is quicker and eas-  
ier on the machine than trying to grind a tree of 3” or more diameter from the top  
down.  
7. Never allow bystanders to within 150 feet of mowing or brush cutting.  
8. Do not use this mower as a bucket to dig up roots and spread out piles of dirt.  
Damaged caused by such activities will result in expensive repairs which will not be  
covered under warranty. This weldment design is strong enough to last for decades  
if cared for properly.  
9. Frequent and routine maintenance procedures should be followed to insure the  
safe and efficient operation of your brush mower  
10. Abuse is indicated by drum damage, where the sides of the knives have left inden-  
tations on the drum. Abuse is also indicated by premature knife failure across the  
whole drum. If cutter abuse is not prevented, ear failure will follow. To prevent  
abuse, always reduce cutting load before significant cutter drum speed is lost.

BASIC OPERATION  
Starting Procedure  
1. While the excavator’s engine is turned OFF, and all moving parts have completely  
stopped, remove outer spindle cover.  
2. Check to see that the brush mower is in the down position and blades are not touch-  
ing the ground. Start the engine and set throttle at idle speed. Important: Do not  
start the operating vehicle until the brush mower has been carefully checked  
for correct assembly and installation. Be sure that all observers are at least  
100 feet clear of the machine.  
3. Check pressure settings and make sure that the brush mower circuit is set to 3000  
PSI and the thumb circuit is set to 2500 PSI.  
4. With low RPM, turn on the auxiliary flow hydraulics. Do not engage auxiliary flow  
hydraulics at a high engine speed.  
5. Slowly bring up the RPM to maximum flow/efficiency. The brush mower should be  
operating at 1500-1800 RPM. The RPM can be checked on the idler end side of  
the mower using the shaft center. To do this, you will need a handheld tachometer  
as shown in the photo below. Simply insert the end of the tachometer into the hole  
in the center shaft. When checking the RPM with this method, it should be around  
1700 at full throttle with nothing else running on the power unit. Use extreme cau-  
tion when checking RPM near rotating parts!  
Auxiliary Hydraulics Control  
Tachometer Usage  
6. Listen and feel for excess vibrations. Should excess vibrations occur, disable auxil-  
iary flow hydraulics and shut the machine down. Determine and correct the prob-  
lem before continuing work.  
7. When work is finished, disable auxiliary flow hydraulics, shut off operating vehicle,  
set parking brake and check hydraulic motor and surrounding parts for excess heat  
or any leaks. Then replace shaft cover.

MAINTENANCE 10  
MAINTENANCE  
ATTENTION  
Before doing any service work, observe the following safety rules:  
1. Remove the ignition key from the operating vehicle and allow all movements to stop  
before leaving the operator’s position and starting any maintenance activities.  
2. Allow all movements to stop before leaving the operator’s position to lubricate or  
clean the machine.  
3. Before working on or underneath the brush mower, place blocks on both sides of  
the operating vehicle tires or treads and under each end of the brush mower to pre-  
vent accidental lowering of the machine.  
Lubrication  
1. GREASE DAILY: Two cutter drum bearings. The grease fitting for the bearing on  
the motor side of the attachment is mounted on the side of the motor housing.  
2. Inspect rubber isolation disk. This disk will last over 1000 hours but should be in-  
spected daily and replaced whenever the cutter drum is removed.  
3. When greasing, apply 6-8 full pumps every eight hours of operation. Apply 6-8 full  
pumps every four hours if running in severe conditions, apply 6-8 full pumps every  
three hours in wet, boggy conditions.  
CAUTION  
Over-greasing seals and bearings can cause damage. If an excessive amount of  
grease is visible, too much grease has been applied.

REPLACING KNIVES 11  
REPLACING KNIVES  
IMPORTANT  
Never operate brush mower with a damaged knife. This will make the  
cutter drum unbalanced and severe damage may result!  
1. Worn knives, bolts, and spacers must be replaced. Neglecting the replacement of  
these parts could cause the cutting drum to run out of balance. Do not mix new  
parts with older, worn parts. Always replace wear washers when blades are  
replaced. Failing to do so could cause the cutter drum to run out of balance.  
2. In order to replace damaged or worn knives, you need a 3/16” punch, a hammer  
and access to the knives on the cutter drum. Once the brush mower is tilted to  
where the knives are exposed, simply take your punch and hammer it against the  
roll pin going through the castle nut and bolt until it pops out. The nut should come  
off easily after that.  
Castle Nut  
Roll Pin  
Shredder Knife  
Hammer Knife  
3. To attach new knives, replace the same as they were removed and tighten the nut  
down past the hole for the roll pin and reinsert the roll pin using the hammer and  
punch.  
ATTENTION IMPORTANT RECOMMENDATION  
Customer & Dealer should always keep replacement knives, hammers and blade  
bolts on hand. DO NOT OPERATE BRUSH MOWER WITH DAMAGED KNIVES.

TRANSPORT  
ATTENTION  
Allow all movements to stop before leaving the operator’s position to lubricate or clean  
the machine. Before working on or underneath the brush mower, place blocks on both  
sides of the operating vehicle tires or treads and under each end of the mower to pre-  
vent accidental lowering of the machine. Remove the ignition key from the operating  
vehicle and allow all movements to stop before beginning work. To transport, disen-  
gage auxiliary hydraulics and lower the machine to a reasonable ride height.  
Removal  
1. Lower the brush mower all the way onto level ground, extend boom and stick to  
reach hoses.  
2. Turn off the excavator and cycle all controls to insure all hydraulic pressure is re-  
lieved.  
3. Unlock the locking devices on the excavator mount, never stand on the attachment.  
4. Unlock mounting devices at the excavator and uncouple hydraulic hoses.  
5. Re start and lift the excavator boom to remove it from the mower.  
6. If transporting excavator and brush mower, leave the shredder mounted and curl  
forwards so that the underside is exposed to the operator as shown above.  
Storage  
1. Clean the brush mower thoroughly.  
2. Lubricate the mower as recommended.  
3. Check hoses and replace if damaged.  
4. Check for worn parts and replace so you will be ready to operate when necessary.

TROUBLESHOOTING 14  
TROUBLESHOOTING  
T= Trouble C= Countermeasure  
T. Where is the serial number for my machine?  
C. The serial number for your brush shredder is stamped next to the mounting bracket on  
the opposite side of the motor.  
Model & Serial Number Plate Location  
Serial Number Stamped On Top Of Mower  
T. Where do I find replacement parts?  
C. Your local Kubota dealer.  
T. How often should I change my knives?  
C. Replacing the cutting knives is a performance issue. When the cut begins to be incon-  
sistent or rough, consider replacing the knives. It is recommended to always keep an  
extra set of knives on hand so that loss of work time is minimal. Your dealers has a  
starter kit of wear parts that shipped with your brush mower.  
T. Do I need to fill the hydraulic motor with oil before I use the brush mower?  
C. No, you do not. Attachments are tested at the factory prior to shipment and come filled  
with high quality hydraulic fluid.  
T. How can I prevent my hydraulic hoses from coming off during operation?  
C. Be careful! Make sure the hoses are pressed all the way into their corresponding fit-  
tings on the operating vehicle. Turn the female coupler collar past bump to lock. Give  
them a slight tug to make sure they are on all the way.  
T. When I am replacing hydraulic fluid, how much should I add?  
C. Consult your KX080 excavator manual for fluid levels and information.  
T. Are there any advantages to reversing cutter drum rotation?  
C. Obviously the first thing is safety. For example, if you want your cutter drum to rotate  
so that it throws debris away from property, then it is advantageous. Also, you can re-  
verse rotation to use the other side of the knives instead of having to buy new ones or  
flip the old ones around.

T= Trouble C= Countermeasure  
T. How do I reverse the cutter drum rotation?  
C. Refer to the Adjustments and Maintenance section of this manual for information on  
reversing the hydraulic hoses at the motor to reverse the cutter drum direction.  
T. How do I replace my knives?  
C. Refer to the Adjustments and Maintenance section of this manual for information  
regarding the replacement of knives.  
T. When connecting my hydraulic hoses, is there a specific way they should be at-  
tached or can any hose go to any fitting on the operating vehicle?  
C. Make sure the engine is turned off and all the functions have been cycled to insure  
all hydraulic back pressure has been relieved. You will notice that one hose has a  
female end and the other hose has a male end. The female hose attaches to the  
male fitting on the operating vehicle and vice versa. Refer to the Basic Operation  
section of this manual for further information regarding plumbing.  
T. I keep blowing the seals on my 40EXT and cannot seem to resolve the issue. What  
should I do?  
C. The main cause of seal ruptures with this machine is a result of high pressure re-  
turn problems. In order to eliminate these problems, let the operating vehicle warm  
up for at least 3-5 minutes before attempting to use any oil-operated functions.  
Check to insure return valve is in the HAMMER / BREAKER clockwise position.  
NOTE: Consult your KX080 excavator manual to insure lift capacities are not ex-  
ceeded. K4080 features custom bolt on hitch mounting to match your existing buckets.  
Safety begins with a thorough understanding of the equipment. Always make sure you  
and your operators read the Operator’s Manual before using the equipment. Pay close  
attention to all safety and operating decals and never operate machinery without all  
shields, protective devices and structures in place. Design, materials and/or specifica-  
tions are subject to change without notice and without liability therefore. Specifications  
are applicable to units sold in Canada, the United States, its territories and posses-
