General Safety Instructions and Practices
SAFETY
A careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to the
owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and observing certain precautions. The first section of this manual includes a list of Safety Messages that, if followed,
will help protect the operator and bystanders from injury or death. Read and understand these Safety Messages
before assembling, operating or servicing this Implement. This equipment should only be operated by those persons who have read the manual, who are responsible and trained, and who know how to do so responsibly.
The Safety Alert Symbol combined with a Signal Word, as seen below, is used throughout this
manual and on decals which are attached to the equipment.The Safety Alert Symbol means:
“ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!” The Symbol and Signal Word
are intended to warn the owner/operator of impending hazards and the degree of possible injury
faced when operating this equipment.
Practice all usual and customary safe working precautions and above all---remember safety is up
to YOU. Only YOU can prevent serious injury or death from unsafe practices.
Indicates an imminently hazardous situation that, if not avoided, WILL result in DEATH OR
VERY SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH
OR SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, MAY result in MINOR INJURY.
Identifies special instructions or procedures that, if not strictly observed, could result in
damage to, or destruction of the machine, attachments or the environment.
NOTE: Identifies points of particular interest for more efficient and convenient operation or repair.(SG-1)
READ, UNDERSTAND, and FOLLOW the following Safety Messages. Serious injury or death
may occur unless care is taken to follow the warnings and instructions stated in the Safety
Messages. Always use good common sense to avoid hazards. (SG-2)
Always maintain the safety signs in good readable condition. If the safety signs are missing, damaged, or unreadable, obtain and install replacement safety signs immediately.

Safety Section 1-2
SAFETY
Never operate the Tractor or Implement until you have read and
completely understand this Manual, the Tractor Operator’s Manual, and
each of the Safety Messages found in the Manual or on the Tractor and
Implement. Learn how to stop the tractor engine suddenly in an
emergency. Never allow inexperienced or untrained personnel to
operate the Tractor or Implement without supervision. Make sure the
operator has fully read and understood the manuals prior to operation.
BEFORE leaving the tractor seat, always engage the parking brake and/
or set the tractor transmission in parking gear, disengage the PTO, stop
the engine, remove the key, and wait for all moving parts to stop. Place
the tractor shift lever into a low range or parking gear to prevent the
tractor from rolling. Never dismount a Tractor that is moving or while the
engine is running. Operate the Tractor controls from the tractor seat only.
(SG-9)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and
responsible can operate the implement with adult supervision, if they
have read and understand the Operator’s Manuals, been trained in
proper operation of the tractor and Implement, and are physically large
enough to reach and operate the controls easily. (SG-11)
Do not mount or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are completely
stopped.(SG-12)
Do not modify or alter this Implement. Do not permit anyone to modify or
alter this Implement, any of its components or any Implement function.
(SG-8)

Safety Section 1-3
SAFETY
Operate this Equipment only with a Tractor equipped with an approved
roll-over-protective system (ROPS). Always wear seat belts. Serious injury
or even death could result from falling off the tractor--particularly during a
turnover when the operator could be pinned under the ROPS. (SG-7)
SAFETY
Operator Safety Instructions and Practices
SAFETY
The operator and all support personnel should wear hard hats, safety
shoes, safety glasses, and proper hearing protection at all times for
protection from injury including injury from items that may be thrown by
the equipment. (SG-16)
PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE
PERMANENT HEARING LOSS! Tractors with or without an Implement
attached can often be noisy enough to cause permanent hearing loss.
We recommend that you always wear hearing protection if the noise in
the Operator’s position exceeds 80db. Noise over 85db over an
extended period of time will cause severe hearing loss. Noise over 90db
adjacent to the Operator over an extended period of time will cause
permanent or total hearing loss. NOTE: Hearing loss from loud noise
[from tractors, chain saws, radios, and other such sources close to the
ear] is cumulative over a lifetime without hope of natural recovery. (SG-I7)
Always read carefully and comply fully with the manufacturer’s
instructions when handling oil, solvents, cleansers, and any other
chemical agent. (SG-22)
KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement
and possible serious injury or death. (SG-24)
Never allow children to play on or around Tractor or Implement. Children
can slip or fall off the Equipment and be injured or killed. Children can cause
the Implement to shift or fall crushing themselves or others. (SG-25)
Be sure you have adequate knowledge of the property you will be working
on. Take time to make yourself aware of any area underground lines or cables. Contact with buried lines or cable could result in serious injury or
death. (STL-1)
Do not put hands or feet under Tiller deck. Blade Contact can result in
serious injury or even death. Stay away until all motion has stopped
and the decks are securely blocked up. (STL-3)

Safety Section 1-4
SAFETY
Extreme care should be taken when operating near loose objects such as
gravel, rocks, wire, and other debris. Inspect the area before tilling. Foreign
objects should be removed from the site to prevent machine damage and/or bodily injury or
even death. Any objects that cannot be removed must be clearly marked and carefully avoided
by the operator. Stop operating immediately if blades strike a foreign object. Repair all damage
and make certain rotor and blades are in good condition before resuming operation. (STL-5)
Equipment Operation Safety Instructions and Practices
Operate the Tractor and/or Implement controls only while properly seated in
the Tractor seat with the seat belt securely fastened around you. Inadvertent
movement of the Tractor or Implement may cause serious injury or death.
(SG-29)
Do not operate the implement while wearing loose fitting clothing. Entanglement of the clothing with the rotating elements can result in serious injury or
even death. Stay clear of all rotating elements at all times. (SSP-03)
Start tractor only when properly seated in the Tractor seat.
Starting a tractor in gear can result in injury or death. Read
the Tractor operators manual for proper starting instructions.
(SG-13)
Never run the Tractor engine in a closed building or without
adequate ventilation. The exhaust fumes can be hazardous to
your health. (SG-23)

Safety Section 1-5
SAFETY
NEVER use drugs or alcohol immediately before or while operating the Tractor and Implement. Drugs and alcohol will affect an operator’s alertness and coordination and therefore
affect the operator’s ability to operate the equipment safely.
Before operating the Tractor or Implement, an operator on prescription or over-the-counter medication must consult a medical professional regarding any side effects of the medication
that would hinder their ability to operate the Equipment safely.
NEVER knowingly allow anyone to operate this equipment
when their alertness or coordination is impaired. Serious injury
or death to the operator or others could result if the operator
is under the influence of drugs or alcohol. (SG-27)
SAFETY
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause
Implement driveline or blade failures resulting in serious injury or death. (SG-26)
SAFETY
Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat
with the seat belt securely fastened around you. Inadvertent movement of the Tractor or
Implement may cause serious injury or death. (SG-29)
There are obvious and hidden potential hazards in the operation of this Implement as in all
power-driven or pulled equipment. REMEMBER! This machine is often operated in rough
terrain conditions that include grass, weeds, gullies, holes, slopes, hidden obstructions and
the like. Serious injury or even death may occur unless care is taken to assure the safety
of the operator and bystanders in the area. Do not operate this machine with anyone in
the immediate area. Stop operating if anyone comes within 25 feet of the equipment.
(STL-4)
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the
rotating parts of the Implement. These objects could then swing outside the housing at
greater velocities than the blades. Such a situation is extremely hazardous and could
result in serious injury or even death. Inspect the area for such objects before working in
the area. Remove any such objects from the site. Never allow the implement to contact
such objects. (STL-6)
Transporting Safety Instructions and Practices
This Implement may be wider than the Tractor. Be careful when operating or transporting
this equipment to prevent the Implement from running into or striking sign posts, guard rails,
concrete abutments or other solid objects. Such an impact could cause the Implement and
Tractor to pivot violently resulting in loss of steering control, serious injury, or even death.
Never allow the Implement to contact obstacles. (S3PT-12)
Be particularly careful when transporting the Implement with the Tractor. Turn curves or go
up hills only at a low speed and using a gradual steering angle. Rear mounted implements
move the center of gravity to the rear and remove weight from the front wheels. Make
certain, by adding front ballast, that at least 20% of the tractor’s weight is on the front wheels
to prevent rearing up, loss of steering control or Tractor tip-over. Slow down on rough or
uneven surfaces to prevent loss of steering control which could result in property damage
or possible injury. Do not transport unless 3-Point lift lever is fully raised and in the latched
transport position. Dropping implement in transport can cause serious damage to the
tractor and/or Implement and possibly cause the operator or others to be injured or killed.

9. OPERATING THE TRACTOR AND IMPLEMENT
OPERATION
THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND
IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE.
The operator must read and understand the Safety and Operation Sections of the implement and tractor
operator’s manuals. These manuals must be read and explained to any operator who cannot read.
Never allow someone to operate the implement and tractor without complete operating instructions.
Before starting any operation, the operator must become familiar with the area to be worked in and
any obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special attention should be paid to foreign debris, rough terrain, steep slopes, and passersby
and animals in the area. OPS-U- 0015
Many varied objects, such as wire, cable, rope, or chains, can become entangled
in the rotating parts of the Implement. These objects could then swing outside the
housing at greater velocities than the blades. Such a situation is extremely hazardous and could result in serious injury or even death. Inspect the area for such
objects before working in the
tue area. Remove any such objects from the site. Never
allow the implement to contact
such objects. (STL-6)
Foreign Debris Hazards
Before operating, inspect the area to make sure
there are no foreign objects that the implement
knives could hit or become entangled with. Remove all foreign objects and debris. If objects are
too big to remove, mark them clearly and be sure
to prevent the implement blades from contacting
them.
If you hit a solid object or foreign debris, stop the
implement and tractor at once. Immediately idle
the engine speed and disengage the PTO. Wait
for all implement rotating motion to stop, then
raise the implement and move the tractor and
implement off the object. Inspect the area and
remove, or mark the location of the debris. Inspect the condition of the implement and make
any needed repairs immediately. Make sure the
knives are not damaged and the carrier is balanced before resuming operation.
Always wear your seat belt securely fastened and only operate the tractor and implement with the
ROPS in the raised position. If the tractor or implement hits a tree stump, rock, or bump, a sudden
movement could throw you off of the seat and under the tractor and/or implement. The seat belt is your
best protection from falling off the tractor and the ROPS provides protection from being crushed during
a tractor roll-over. OPS-T-0003

Operation Section 4- 19
OPERATION
Never attempt to adjust the rotary tiller while the tractor is running.
5. Raise the tiller and remove the blocks. Lower the tiller to the ground.
6. With the tractor at idle RPM and the tiller lifted off of the ground, engage PTO and slowly advance
throttle to 540 PTO RPM.
OPERATION
NOTE: Rotary tiller is designed to run at 540 PTO RPM only.
7. Select a low gear for the tractor and begin to move forward. Tractor ground speed is to be controlled by gear selection only and not engine speed. As the tractor moves forward, slowly lower
the tiller down. Allow the tiller tines to gradually engage the ground.
NOTE: Do not allow the tractor engine or rotary tiller to bog down or stall. This causes undue wear
and tear on the tiller and tractor. If this continues to happen reduce ground speed and raise tilling
depth of rotary tiller. Never attempt to remove objects from the rotor bar until the tractor has been
shut down and the tiller tines have completely stopped.
Never travel at a fast ground speed while using the tiller, this could damage
it. Never attempt to turn the tractor or travel in reverse with the PTO engaged
and the tiller in the ground. Always raise the tiller out of the ground when backing up or attempting to turn. Failure to do so may cause damage to the tiller.
8. After each use clean all debris from the tiller tines. Replace any missing or illegible safety decals.
Inspect for any damaged or worn parts and replace before next use. Store rotary tiller in a dry environment.
Extreme care should be taken when operating near loose objects such as gravel,
rocks, wire, and other debris. Inspect the area before tilling. Foreign objects
should be removed from the site to prevent machine damage and/or bodily injury or even death. Any
objects that cannot be removed must be clearly marked and carefully avoided by the operator. Stop
operating immediately if blades strike a foreign object. Repair all damage and make certain rotor
and blades are in good condition before resuming operation. (STL-5)
9.3 Bystanders/Passersby Precautions
If a bystander comes within 300 feet of the tractor while the implement is being operated, stop the
tractor at once, idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past the 300 foot distance. OPS-T-0004
9.4 Engaging the Power Take Off (PTO)
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement must be completely lowered and the deck positioned at a safe operating height. NEVER
engage the PTO with the implement in the raised position. Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to the on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you hear unusual noises or
see or feel abnormal vibrations, disengage the PTO immediately. Inspect the implement to determine
the cause of the noise or vibration and repair the abnormality. OPS-U- 0027
RTG SERIES TILLER

Operation Section 4-20
OPERATION
Do not put hands or feet under Tiller deck. Blade Contact can result in
serious injury or even death. Stay away until all motion has stopped and
the decks are securely blocked up. (STL-3)
9.5 PTO RPM and Ground Speed
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can
cause Implement driveline or blade failures resulting in serious injury or death. (SG-26)
9.6 Shutting Down the Implement
To shut down the implement, first bring the tractor
to a complete stop. Then slow down the implement
by reducing the engine speed before disengaging
the PTO. Wait for all motion to stop before proceeding to drive or shut down the tractor.
Park the tractor on a level surface, place the transmission in park or neutral and apply the parking
brake, lower the attached implement to the ground,
shut down the engine, remove the key, and wait for
all motion to come to a complete stop before exiting
the tractor. OPS-T-0007
RTG SERIES TILLER
© 2019 Alamo Group.Inc
09/19
Operation Section 4-21
OPERATION
Ground speed for operating will depend upon the type of cultivation. Recommended speed for efficient implement
performance is between 2 and 5 mph. Operate the implement at its full rated PTO speed to maintain knife speed
for a clean operation. Refer to the tractor operator’s manual or the tractor instrument panel for the engine speed
and gear to provide the required PTO and desired ground speed. Make sure that the implement is operating at
its full rated speed before entering the area. If it becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually. Ground speed is achieved by transmission gear selection and not by
the engine operating speed. The operator may be required to experiment with several gear range combinations
to determine the best gear and range which provides the most ideal performance from the implement and most
efficient tractor operation. As the severity of operating conditions increase, the ground speed should be decreased
by selecting a lower gear to maintain the proper operating PTO speed. OPS-T-0006
OPERATION
10. DISCONNECTING THE IMPLEMENT FROM THE TRACTOR
Before disconnecting the implement, the PTO must be disengaged and knife rotation at a complete stop. Move
the implement to a level storage location and lower it to the ground. If the implement is not resting securely on
the ground, block the implement up securely before attempting to disconnect it from the tractor.
OPERATION
Use extreme care to keep feet and hands from under the implement and clear of any pinch points caused by
the tractor hitch arms and implement pins. OPS-T-0008
Never stand or allow another person to stand between a running Tractor and the Implement
when disconnecting the Implement from the Tractor 3-point hitch.
Always shut the Tractor completely down, place the transmission in park, and set the parking brake before you or anyone else attempts to connect or disconnect the Implement and
Tractor hitches. (S3PT-15)
To disconnect the implement, first extend the tractor 3-point hitch top link to remove tension on the top link hitch
pin. When the pin is loose and easy to rotate, remove the pin from the implement. Next remove both lower hitch
pins.
After disconnecting the 3-lift points, remove the implement driveline from the tractor PTO shaft. Lay the driveline
down carefully to avoid damaging the driveline or its shield. Do not let the driveline fall into mud or dirt, which
can contaminate the bearing and shorten the life of the driveline.

11. IMPLEMENT STORAGE
Properly preparing and storing the implement at the end of the season is critical to maintaining its appearance and to help
ensure years of dependable service. The following are suggested storage procedures:
•
•
•
•
It is critical that driveline clutches slip when an obstacle or heavy load is encountered to avoid implement and/
or tractor damage. If the implement sits outside for an extended period of time or is exposed to rain and/or
humid air, the clutch lining plates must be inspected to ensure they are not frozen together from rust or corrosion.
If the implement has been exposed to such conditions, at the start of each operating season, and any time it is
suspected that the slip clutch plates may be frozen together, readjust the slip clutch as detailed in Seasonal
Clutch Maintenance of the maintenance section in this manual. OPS-T-0010
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
12. TRANSPORTING THE TRACTOR AND IMPLEMENT
Inherent hazards of operating the tractor and implement and the possibility of accidents are not left behind when you finish
working in an area. Therefore, the operator must employ good judgement and safe operation practices when transporting
the tractor and implement between locations. By using good judgement and following safe transport procedures, the possibility
of accidents while moving between locations can be substantially minimized. OPS-U- 0017
13. DRIVING THE TRACTOR AND IMPLEMENT
Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the weight
of the implement and the tractor operating controls are set for safe transport. To ensure safety while driving the
tractor with an attached implement, review the following. OPS-U- 0012
Never run the Tractor engine in a closed building or without adequate ventilation. The exhaust
fumes can be hazardous to your health. (SG-23)
RTG SERIES TILLER

Operation Section 4-23
OPERATION
Thoroughly clean all debris off the implement to prevent damage from rotting grass and standing water.
Lubricate all implement grease points and fill gearbox oil levels as detailed in the maintenance section.
Tighten all bolts and pins to the recommended torque.
Check the implement for worn and damaged parts. Perform repairs and make replacements immediately so that the implement will be ready for use at the start of the next season.
• Store the implement in a clean, dry place with the implement housing resting securely on blocks or at ground level.
• Keep the driveline yoke from sitting in water, dirt and other contaminants.
• Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the implement.
OPERATION
Transport only at speeds where you can maintain control of the
equipment. Serious accidents and injuries can result from operating
this equipment at high speeds. Understand the Tractor and Implement and how it handles before transporting on streets and highways. Make sure the Tractor steering and
brakes are in good condition and operate properly.
OPERATION
Before transporting the Tractor and Implement, determine the proper transport speeds
for you and the equipment. Make sure you abide by the following rules:
Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes
smoothly to determine the stopping characteristics of the Tractor and Implement. As
you increase the speed of the Tractor the stopping distance increases. Determine the
maximum transport speed not to exceed 20 mph (30 kph) for transporting this equipment.
Test the equipment at a slow speed in turns. Increase the speed through the turn only
after you determine that the equipment can be operated at a higher speed. Use extreme
care and reduce your speed when turning sharply to prevent the tractor and implement
from turning over. Determine the maximum turning speed for you and this equipment
before operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds which allow you to properly
control the equipment.
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty
brakes or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance increases: use extreme care and reduce your speed. When operating in
traffic always use the Tractor’s flashing warning lights and reduce your speed. Be aware
of traffic around you and watch out for the other guy. (SG-19)
Before transporting the tractor and implement, idle
the tractor engine, disengage the PTO and wait
for all implement moving parts to come to a complete stop. Once all implement parts are completely stopped, raise the implement to transport
height.
NOTE: When raising the implement, maintain 1”
clearance between the driveline and implement
deck. If additional implement deck height is
needed for transport, disconnect the driveline from
the tractor and secure its end to the implement
deck. The implement can then be raised to the
maximum lift height. OPS-T-0011

13.1 Brake and Differential Lock Setting
OPS-U- 0013
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty
brakes. When operating down a hill or on wet or rain slick roads, the braking distance
increases; use extreme care and reduce your speed in these conditions. When operating in traffic, always use the Tractor’s flashing warning lights and reduce your
speed. Be aware of traffic around you and watch out for the other guy.
If the tractor’s hydraulic pump is not independent of the
tractor PTO, or if the tractor PTO has to be run to have hydraulic power, disconnect the implement driveline from the
tractor PTO output shaft. Secure the driveline to the implement deck to prevent driveline damage or loss during
transport. OPS-T-0012
RTG SERIES TILLER

Operation Section 4-25
OPERATION
Make sure the tractor brakes are in good operating
condition. Tractor brakes can be set to operate independently allowing single rear wheel braking action or locked together to provide simultaneous
rear wheel braking. FOR MOST DRIVING AND
OPERATING CONDITIONS, THE BRAKE PEDALS SHOULD BE LOCKED TOGETHER TO
PROVIDE THE MOST EFFECTIVE BRAKING
ACTION.
Always disengage the tractor differential lock when
turning. When engaged the differential lock will
prevent or limit the tractor from turning. During normal cutting conditions, locking the differential provides no benefit and should not be used.
OPERATION
13.2 Transporting on Public Roadways
OPERATION
Extreme caution should be used when transporting the tractor and implement on public roadways.
The tractor must be equipped with all required safety warning features including a SMV emblem and
flashing warning lights to alert drivers of the tractor’s presence. Remember that roadways are primarily
designed for automotive drivers and most drivers will not be looking out for you, therefore, you must
look out for them. Check your side view mirrors frequently and remember that vehicles will approach
quickly because of the tractor’s slower speed. Be extremely cautious when the piece of equipment
that you are towing is wider than the tractor tire width and/or extends beyond your lane of the road.
Make sure that a proper size safety tow chain is secured between the tractor and implement before
entering a public road. OPS-U- 0019
Make certain that the “Slow Moving Vehicle” (SMV) sign is installed
in such a way as to be clearly visible and legible. When transporting
the Equipment use the Tractor flashing warning lights and follow all
local traffic regulations. (SG-6)
The SMV (Slow-Moving Vehicle) emblem is universal symbol used to alert drivers of the presence of equipment traveling on roadways at a
slow speed. SMV signs are a triangular bright orange with reflective red trim for both easy day
and night visibility. Make sure the SMV sign is
clean and visible from the rear of the unit before
transporting the tractor and implement on a public roadway.
Replace the SMV emblem if faded, damaged, or
no longer reflective. OPS-U- 0020
Make sure that all tractor flashing warning lights,
headlights, and brake/tail lights are functioning
properly before proceeding onto public roads.
While newer model tractors have plenty of lighting to provide warning signals and operating
lighting, most older models are only equipped
with operating lights.
Consult an authorized tractor dealer for lighting
kits and modifications available to upgrade the

MAINTENANCE SECTION
Maintenance Section 5-1
MAINTENANCE
Before operating your Tiller, make sure it is properly lubricated and thoroughly inspected. Only a minimum of time and effort is required to regularly lubricate and maintain this machine to provide long life and trouble free operation.
MAINTENANCE
Always disengage the PTO before raising the Tiller for transporting or
making adjustments.
LUBRICATION INFORMATION
Do not let excess grease collect on or around parts, particularly when operating in sandy
areas. Severe or unusual conditions may require more frequent lubrication.
Use an SAE multi-purpose, lithium-type grease for all locations shown. Be sure to clean the
fitting thoroughly before using grease gun.
OUTBOARD BEARING
Grease the Outboard Bearing located
on the right hand side of the tiller.
GREASE FITTING
Lubricate every 8 Hours
LUBRICATION
Before each use gearbox should be checked to be sure oil is at the proper levels. Operating the Machine with
the oil levels to low or to high can severly damage the machine. If it is determined that oil is needed follow these
steps.
NOTE: Make sure the Gearbox is level prior to removing the Inspection plug. Tilting forward may result
in over filling, tilting back may result in under filling. Use GL5-85W 140 or Triple Zero Grease which can
be poured and has an “EP” Extreme Pressure Additives in the Gearboxes.

GENERAL MAINTENANCE
BLADES
Owner / Operator should routinely check the machine for broken and severly worn blades and replace
as necessary to keep the tiller in its best working condition.
MAINTENANCE
FASTENERS
Check the tiller for loose pins, bolts or broken fasteners and tighten or replace as necessary. Refer
to Proper Bolt Tongue craft supplied in this manual for proper torque settings of fasteners.
SAFETY DEVICES
Make sure all Safety Shields and Guards are in place and in good working order.
Check to be sure all Safety Decals are in place and legible. Replace if needed.
STORAGE
Your implement tiller represents an investment from which you should get the greatest possible benefit. Therefore, when the season is over, the tiller should be thoroughly checked and prepared for
storage so that a minimum amount of work will be required to put it back into operation for the next
season.
The following are suggested storage procedures:
1. Thoroughly clean the tiller.
2. Lubricate the tiller as covered in Maintenance Section.
3. Tighten all bolts and pins to the recommended torque.
4. Check the tiller for worn or damaged parts. Make replacements immediately.
5. Store the tiller in a clean, dry place.
6. Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the tiller.
7. Store unit away from human activity.
8. Do not park equipment where it can be exposed to direct contact to livestock.
Damage to machine or livestock could result.
9. Make sure to park the machine on a hard , level surface and engage safety devices.
PROPER TORQUE FOR FASTENERS
The chart lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer
to this chart to determine the grade of bolts and the proper torque except when specific torque values are
assigned in manual text.
RECOMMENDED TORQUE IN FOOT POUNDS UNLESS OTHERWISE STATED IN THE MANUAL
NOTE: These values apply to fasteners as received from supplier, dry or when lubricated with normal engineoil. They do not apply if special graphited or molydisulphide greases or other extreme pressure lubricants areused. This applies to both UNF fine and UNC coarse threads.
