Operational Safety
 Before operang this machinery, read the
owner’s manual thoroughly.
 Do NOT operate this machine without proper
training. It is the owners responsibility to en‐
sure all Operators are properly trained in the
appropriate language.
 Use OSHA approved eye, ear and head protec‐
on to protect the Operator from flying debris
and noise.
 Avoid wearing loose clothing as it can inadvert‐
ently be drawn into moving parts.
 Never use drugs or alcohol before or during op‐
eraon of this machine.
 Only operate this machine when it is in good
working order on an appropriate power unit
that is in good working order, and with all
guards and safety devices in place and func‐
oning.
 Be aware of the machine’s weight and its effect
on the stability of the power unit.
 Use flashing warning lights when operang on
highways, except when prohibited by law.
 Always inspect area to be worked to ensure
that the jobsite is free from obstacles and de‐
bris that could injure the operator or damage
the machine. Operate at a safe speed (typically
0‐5 mph) in consideraon of the local terrain,
moving slower when operang on or near
slope, ditches or drop‐offs.
 Avoid running the machine along the ground in
rocky areas as this could create dangerous dis‐
charge.
 Never allow children or other persons to ride
on this mower.
 Keep bystanders and children clear of the work
area during operaon as debris can be dis‐
charger in a dangerous manner. The minimum
safe distance is 100 .
 Be aware that this machine may be wider than
the power unit, and cauon should be used to
avoid clipping or running over trees, signs or
posts that may be in the way of the machine.
 Avoid operaon that would allow hydraulic
lines to be pinched or severed. In the even of a
hydraulic leak, hydraulic fluid may have suffi‐
cient force to penetrate skin, which requires
immediate medical aenon.
 Do not turn so sharp or li the mower so high
that the driveline produces a sever knocking as
this will cause the accelerated wear of drive
train components. The drum should not be ro‐
tang when the deck is lied.
 Be aware of the risks to equipment and grass
fires. To migate those risks:
* Do not smoke or have open flame in
the work area.
* Do not operate in areas that have been
freshly burned or are sll burning.
*Do not allow clippings/debris to collect
near hydraulic components or bearings.
* Avoid areas with high fire risk: dry
grass, brush or trees.
 Operaon of this machine should be stopped
immediately if the Operator’s vision becomes
obscured by the discharge of debris and dust.
Also avoid operang this machine in unusually
foggy or dusty condions or at night.

 Keep away from the machine unl all the ener‐
gy has dissipated. This includes the complete
stopping of the drum’s rotaon as well as the
dissipaon of pressure in the hydraulic lines.
 In the event that a failure does occur during
operaon or if the machine begins to produce
excessive noise or vibraon, shut the machine
down immediately and repair before any con‐
nued use.
 Never leave the machine unaended unless it
is in the storage or transport posion.
 In addion to the design and configuraon of
equipment, hazard control and accident pre‐
venon are dependent upon the awareness,
concern and prudence and requires suitable
training of personnel involved in the opera‐
on, transport, maintenance and storage of
equipment.
Maintenance Safety
 Before performing maintenance on this ma‐
chine, read the owner’s manual thoroughly.
 Maintenance should only be performed by
properly trained individuals. It is the Owner’s
responsibility to ensure all individuals involved
in maintaining the machine are properly
trained in the appropriate language.
 Be sure to inspect all safety devices before
each use. If safety devices are worn in such a
way that they can no longer properly perform
their guarding funcon, contact your nearest
Vrisimo dealer for replacements.
 Maintain all safety decals and make sure they
are visible to the operator. If decals are worn,
contact your nearest Vrisimo dealer for re‐
placements.
 Replace cracked or broken blades with new
ones. Don not aempt to weld damaged
blades . This can cause damage that could re‐
sult in the blade being thrown from the shred‐
der.
 Wear gloves and eye protecon and exercise
care when handling blades as they can be
sharp. Also be alert to worn or damaged surfac‐
es that could have sharp edges.
 Disengage PTO, shut off engine and allow all
movement to stop before leaving the opera‐
tor’s posion to adjust, lubricate, clean, or un‐
clog the machine. Do not try to uncouple hy‐
draulic hoses unless the pressure has ade‐
quately dissipated.
 Before working on or underneath the machine,
place blocks on both sides (front and back) of
power unit’s res or treads and under each end
of the aachment to prevent accidental lower‐
ing of the machine. Also, remove the ignion
key from the power unit and allow all move‐
ment to stop before beginning work.

Basic Operation
Attaching to the Power Unit
Note: When you ordered your Vrisimo Aachment,
details about your Power Unit were provided to custom
match your Aachment to your Power Unit. While Vri-
simo Aachments can be aached to a variety of
different tractors, your Aachment is specifically con-
figured for your Power Unit and can not necessarily be
placed on another Power Unit as is. Specifically, the
mount category and gearbox/pulley were selected to
mate to your Power Unit’s hitch and opmize perfor-
mance based on your PTO output, respecvely. Your
Aachment should only be connected to Power Units
that share the same specificaons as the informaon
on the Power Unit you provided. Aachment instruc-
ons are for the most common configuraon: 3-point
hitch with a PTO output of 540 rpm.
The person that is aaching your Vrisimo prod‐
uct should be familiar with the aachment and remov‐
al of equipment from a 3‐point hitch and be able to do
so safely. Aachment should be performed on flat
ground away from obstrucons. During aachment,
keep hands out of pinch points and away from the
blades to avoid injury.
The tractor’s drawbar should be placed to its
shortest point, if there is sll insufficient clearance
then it should be removed. If your tractor has load
and depth control, lock out control so it will not func‐
on but be in “free float.”
1) Back the tractor up to the front of the machine so
that the li links are in line with the mower’s hitch
pins.
2) Shut off the engine and disengage the PTO. Block
the tractor’s wheels before placing yourself be‐
tween the tractor and the aachment.
3) Aach the tractor’s le and right li links to the
corresponding hitch pins of the aachment, secur
ing both connecons with lynch pins.
4) Adjust the sway bars so that there is a minimum
side slack and be sure the stabilizers are ght.
5) Aach the tractor’s top link to the “A” frame of the
aachment and adjust the top link to the approxi‐
mate desired cung height.
6) Aach the PTO to the tractor by pushing in on the
quick disconnect pin. Remember, the tube end
goes to the aachment and the bar end goes to
the tractor.
7) With the aachment and PTO line connected check
the drive sha through the enre liing range
checking for binding, booming, uncoupling or
aachment contact.
Starting Procedure
The Operator should be properly trained on the
use of your Vrisimo Aachment and wearing the ap‐
propriate safety gear. Do not start the Power Unit un‐
l the Aachment has been checked for proper assem‐
bly and installaon. This includes the appropriate con‐
necon of the hitch and PTO 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 PTO with the motor above idle speed.

Sanitizer by
2) With the motor at low RPM engage the PTO out‐
put.
3) Slowly bring the throle up to 540 RPM. If the
Aachment produces excessive noise or vibra‐
on, disengage the PTO and shut down the Pow‐
er 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.
Running Your Attachment
1) Determine ground speed based on terrain and
material being cut. This will typically fall within
the 0‐5 mph range.
2) Posion skid shoes between 1/2‐3” off the
ground; skid shoes are not meant to run on the
ground.
3) The mower and skid shoes should be level with
the ground, the height of the mower can be ad‐
justed with the back gauge roller which runs
along the ground.
4) Adjust the sway bars so that there is a minimum
side slack and be sure the stabilizers are ght.
5) Aach the tractor’s top link to the “A” frame of
the aachment and adjust the top link to the ap‐
proximate desired cung height.
6) Aach the PTO to the tractor by pushing in on
the quick disconnect pin. Remember, the tube
end goes to the aachment and the bar end goes
to the tractor.
7) With the aachment and PTO line connected
check the drive sha through the enre liing
range checking for binding, booming, uncou‐
pling or aachment contact.
Shut Down Procedure
1) When work is completed, disengage the PTO
drive and posion it for storage or transport (See
the “Transport, Removal and Storage ” secon for
details on proper storage). Shut off Power Unit
and set parking brake, wait for the aachment to
stop rotang.
2) Visually inspect the PTO sha, all the bearings
and gearbox for excessive heat or leaks.

Adjustments & Maintenance
Note: Before performing maintenance, ensure all mo‐
on has stopped and that the Power Unit is powered
down with ignion key removed. Before working on
or underneath the mower, place blocks on both sides
of the Power Unit’s res and underneath both ends of
the mower to prevent accidental lowering of the ma‐
chine.
Cut Height Adjustments
1) The cung height of the mower can be adjusted
from 0‐4”. Adjusng is done by shortening or
lengthening the top‐link. Under no circumstances
should the knives contact the ground!
2) The enre weight of the mower should be on the
back gauge roller. The skid shoes should be adjust‐
ed so there is 1/2”‐3” clearance between them
and the ground. The shoes are for added protec‐
on against tree roots, ridges or borders and are
not designed to slide on the ground. Adjust the
back gauge roller by removing the bolts from both
sides and reseng It to the correct height.
Wear Components
Wear components such as knives, belts and bear‐
ings may wear at different rates and so
each should be inspected for wear independently.
1) Knives should be replaced when they are dull.
A) When individual knives, bolts or spacers
become worn or damaged they must be re‐
placed with hardware saved from your previ‐
ous knife replacement. Replacing an individ‐
ual staon with new hardware could cause
the cuer drum to run out of bal‐
ance. When replacing hardware at all the
staons, some old hardware should be saved
to replace future broken hardware.
B) Replacing the complete knife assembly is
done by removing the 3/8” carriage bolts
from the hole cover, removing the hole cov‐
er as well. Remove the hanger rod and re‐
move old knife assembly as you remove
hanger rod. When you re‐insert hanging rod
insert new knife assembly in its staon. Re‐
aach the hole cover and carriage bolts, re‐
peat this process unl completed.
2) Decals that are no longer visible, damaged, or lost
should also be replaced.
3) Skid shoes should be replaced as needed.
4) Belt adjustment is done by adjusng the tension
rod.
Cleaning Your Mower
1) Check for excessive grease in bearing areas on the
pulley side of the mower. Make sure that grease is
not allowed to get into the belt areas.
2) Clean any clippings from the gearbox areas, pulley
areas and anywhere else that is prone to excessive
heat where fire can start.
3) Clean the inside of the 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 cuer drum can cause
imbalance.
4) Preserve damaged decals or replace them if they
are unreadable. Decal kits can be obtained from
your local Vrisimo dealer.

Frequently Asked Questions
Q. Where do I find replacement parts?
R. First check your local tractor dealer and if they do not have parts, ask them to order from the Vrisimo fac‐
tory.
Q. How oen should I change my knives?
R. Replacing the cung knives is enrely up to the owner. When the cut begins to be inconsistent or rough,
consider replacing the knives. It is recommended to keep an extra set of knives on hand so that loss of
work me is minimal.
Q. How oen should I replace my belts?
R. If you are experiencing repeated slipping or breaking of belts, try adjusng the level of tension. If this does
not remedy the problem, replace the belt. Consider having an extra belt on hand as well.
Q. Do I need to fill the gearbox with oil before I use the mower?
R. No, the gearbox comes full with oil. Use 90 weight oil when replacing.
Q. What do I do if my belts are wearing out too fast or burning up?
R. First check belt tension. Belts should have about 3/8” sway in them. Adjust tension accordingly. If this
does not help, check the height of the grass you are mowing. If the grass is over 2 feet tall, you might have
to adjust mower cung height upwards and slow the speed of your travel to reduce belt slippage.
Q. My side skid shoes are wearing out too quickly. What do I do?
R. Operate the mower with the side skid shoes 0.5‐3 inches off the ground. The side skid shoes are meant to
collide only with mounds or objects in the field. The rear roller is the only part of the mower that should
touch the ground during operaon.
Q. How can I prevent my PTO sha from coming off during operaon?
R. Be careful! Make sure the sha is slid all the way on and the safety pin is in the locked posion.

Frequently Asked Questions
Q. When I am replacing gear oil, how much should I add?
R. When replacing gear oil, fill from the Upper‐middle fing and when oil begins to come out, the
box is full.
Lower-Middle Fitting
Q. Are there any advantages to reversing cuer drum rotaon?
R. Whether or not reversing cuer drum is advantageous depends on the applicaon. In most, normal
rotaon is a reverse rotaon. This means that the cuer drum rotates in a fashion that would throw
grass or clippings towards the tractor. The only advantage to reversing rotaon would be if you are
mowing in industrial applicaons such as along freeways, in places with large amounts of debris (i.e.
plasc, metal, rocks), or using a front mount applicaon. There are typically no advantages as far as the
grade of cut you will get, but rather safety advantages as stated above.
Q. How do I reverse cuer drum rotaon?
R. To reverse cuer drum rotaon, simply un‐mount the gearbox from its current posion, remove the
safety cover from the other sha of the gearbox and rotate the gearbox so that the previously covered
sha is the one that will be driven by the PTO. Install the safety covers and it is ready to go. Note:
Scoop knives must be rotated to accommodate for a reversed cuer drum rotaon.
Q. How do I replace my knives?
R. Replacing the knives may vary depending on your model of mower/shredder. See the Adjustments/
Maintenance secon for detailed informaon.
Q. When connecng my PTO sha, can I put it on either way or should a specific side go to the mower/
shredder and the other to the tractor?
R. The PTO shas for these mowers/shredders are side specific. The tube half of the PTO sha goes to
the mower/shredder and the bar half of the PTO sha goes to the tractor.
