SAFETY
Operator Safety Instructions and Practices
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.
(SG-4)
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. Inadvertent contact with controls can cause the
Implement to shift or fall crushing themselves or others. (SG-25)
HT419H 03/19

Safety Section 1-3
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)
SAFETY
SAFETY
DO NOT 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)
Prolonged operation may cause operator boredom and fatigue affecting safe operation.
Take scheduled work breaks to help prevent these potentially impaired operating
conditions. Never operate the Implement and Tractor in a fatigued or bored mental state
which impairs proper and safe operation. (SG-32)
Use extreme caution when getting onto the Implement to perform repairs, maintenance and
when removing accumulated material. Only stand on solid flat surfaces to ensure good
footing. Use a ladder or raised stand to access high spots which cannot be reached from
ground level. Slipping and falling can cause serious injury or death. (SG-33)
DO NOT operate this Implement on a Tractor that is not properly maintained. Should a
mechanical or Tractor control failure occur while operating, immediately shut down the
Tractor and perform repairs before resuming operation. Serious injury and possible death
could occur from not maintaining this Implement and Tractor in good operating condition.
(SG-36)
Extreme caution should be used by the Tractor operator when operating near passersby.
Stop raking if anyone comes within 25 feet of the Implement to prevent possible passerby
injury or death from being struck from a thrown object, entanglement with the rakes, or run
over. (SRK-01)
Equipment Operation Safety Instructions and Practices
Never leave the Tractor and Implement unattended while the Implement is in the lifted
position. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop
of unit with injury or death by crushing. To properly park the implement when disconnecting
it from the tractor, lower the stand and put the retaining pin securely in place, or put a secure
support under the A-Frame. Lower the implement carefully to the ground. Do not put hands
or feet under lifted components. (S3PT-1)
Do not back up with this implement. Backing could damage the machine or its components.
(S3PT-4)

Safety Section 1-4
SAFETY
Use extreme care when lowering or unfolding the implement’s wings. Make sure no
bystanders are close by or underneath the wings. Allow ample clearance around the
implement when folding or unfolding the wings. Use extreme caution around buildings or
overhead power lines. (S3PT-05)
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)
Operate this Implement only in conditions where you have clear visibility in daylight or with
adequate artificial lighting. Never operate in darkness or foggy conditions where you cannot
clearly see at least 100 yards in front and to the sides of the tractor and implement. Make
sure that you can clearly see and identify passersby, steep slopes, ditches, drop-offs,
overhead obstructions, power lines, debris and foreign objects. If you are unable to clearly
see these types of items discontinue operating this equipment.(S3PT-21)
Operate this Equipment only with a Tractor equipped with an approved rollover-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)
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)
BEFORE leaving the tractor seat lower the implement, set 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)

Safety Section 1-5
SAFETY
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 tall 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. (S3PT-07)
SAFETY
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
SAFETY
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)
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)
Do not operate this Equipment with hydraulic oil or fuel leaking. Oil
and fuel are explosive and their presence could present a hazard. Do
not check for leaks with your hand! High-pressure oil streams from
breaks in the line could penetrate the skin and cause tissue damage
including gangrene. To check for a hose leak, SHUT the unit ENGINE
OFF and remove all hydraulic pressure. Wear oil impenetrable gloves,
safety glasses and use cardboard to check for evidence of oil leaks. If
you suspect a leak, REMOVE the HOSE and have it tested at a Dealer.
If oil does penetrate the skin, have the injury treated immediately by a
physician knowledgeable and skilled in this procedure. (SG-15)
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
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 Section 1-6
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)
In case of mechanical difficulty during operation, place the transmission in the park
position, set the parking brake, shut down all power, including the PTO and the engine and
remove the key. Wait until all rotating motion has stopped before dismounting. (SG-39)
Objects such as wire, cable, rope, and chain can become entangled in the
rotating parts of the raking components causing mechanical damage.
Entangled items caught in the rakes can sling outward possibly injuring or
entangling the operator or passersby. Any objects that might become
entangled in a raking component should be removed from the area before
operating the rake. (SRK-02)
DO NOT allow any person under a folded wing unless wing is securely
locked up or supported. DO NOT approach the Implement unless the
Tractor is turned off and all motion has ceased. Never work under the
frame work, or any lifted component unless the implement is securely
supported or blocked up. A sudden or inadvertent fall by any of these
components could cause serious injury or even death. (STI-03)
Connecting or Disconnecting Implement Safety Instructions & Practices
The rotating parts of this machine continue to rotate even after the PTO has been turned off.
The operator should remain in the operator’s seat for 60 seconds after the brake has been
set, the PTO disengaged, the tractor turned off, and all evidence of rotation has ceased.
(S3PT-10)

Safety Section 1-7
SAFETY
Do Not operate this equipment in areas where insects such as bees, may attack you and/or
cause you to lose control of the equipment. If you must enter in such areas, use a tractor
with an enclosed Cab and close the windows to prevent insects from entering. If a tractor
cab is not available, wear suitable clothing including head, face, and hand protection to
shield you from the insects. Attacking insects can cause you to lose control of the tractor,
which can result in serious injury or death to you or bystanders. Never dismount a moving
tractor. (SG-40)
SAFETY
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in
excessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.
(S3PT-14)
SAFETY
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)
When attaching the Implement input driveline to the Tractor PTO, it is important that the
connecting yoke spring activated locking collar slides freely and the locking balls are seated
securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth
several times to ensure it is securely attached. A driveline not attached correctly to the
Tractor PTO shaft could come loose and result in personal injury and damage to the
Implement. (S3PT-17)
Before operating the Implement, check to make sure the Implement input driveline will not
bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates
the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out
can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and
through the support bearings or downward onto the PTO shaft, breaking it off. A broken
driveline can cause personal injury. (S3PT-18)
Never unhitch without using the Tongue Jack. The Tongue is very heavy. Attempting to lift
the Tongue without using the Tongue Jack could cause strains or other injury. Allowing the
tongue to fall suddenly and unexpectedly could result in crushing injury. Use the Tongue
Jack for lifting the Implement only. Overloading the Tongue Jack can cause failure with
possible serious bodily injury or even death. (STI-04)
On a fully-assembled unit, do not remove the Wing Retaining Strap until hoses are attached
to the tractor and the Wing Cylinders are filled with oil. Lower the Wings slowly and
carefully. Keep bystanders away during operations. (STI-05)

SAFETY
Transporting Safety Instructions and Practices
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.
Allow sufficient clearance for the Implement to swing outward while turning. Implements
carried behind the Tractor will swing outside the tire path when making turns. Contacting a
solid object while turning will cause equipment damage and possible injury. (S3PT-20)
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)

SAFETY
(S3PT-02)
SAFETY
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.
SAFETY
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)
Be particularly careful when transporting the Implement using the tractor. Turn curves or
go up or down hills only at a low speed and at a gradual steering angle. Make certain that
at least 20% of the tractor’s weight is on the front wheels to maintain safe steerage. Slow
down on rough or uneven surfaces. (STI-01)
When the Wings are folded for transport, the center of gravity is raised and the possibility of
overturn is increased. Drive slowly and use extreme caution when turning on hillsides.
Overturning the Implement could cause the Implement to overturn the Tractor and vice
versa resulting in serious injury or even death. Never fold wings on a hillside...the
Implement or unit may overturn. (STI-02)
Only tow the Implement behind a properly sized and equipped Tractor
which exceeds the weight of the Implement by at least 20%. DO NOT
tow the Implement behind a truck or other type of vehicle. Never tow the
Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH. (STI-06)

Safety Section 1-10
SAFETY
Secure the Implement for transport before traveling on public roads. For pull-type
Implements, secure the center axle using cylinder stops or transport pin and properly attach
a safety chain between the Implement and Tractor. Secure wings in upright position on
folding Implements using wing transport locks. (STI-7)
Always keep a careful lookout and use extreme care when working
around overhead obstructions and electrical power lines.
The
Implement wing can be over 10 feet high. Never allow the Implement
wing to come within 10 feet of any power line. (STI-8)
Maintenance and Service Safety Instructions and Practices
Make sure the PTO shield, integral driveline shields, and input shields
are installed when using PTO-driven equipment. Always replace any
shield if it is damaged or missing. (S3PT-8)
Relieve hydraulic pressure prior to doing any maintenance or repair work
on the Implement. Place the Implement on the ground or securely
blocked up, disengage the PTO, and turn off the tractor engine. Push
and pull the Remote Cylinder lever in and out several times prior to
starting any maintenance or repair work. (S3PT-09)
Always disconnect the main PTO Driveline from the Tractor before performing service on
the Implement. Never work on the Implement with the tractor PTO driveline connected and
running. Rotating Parts, Blades or Drivelines could turn without warning and cause
immediate entanglement, injury or death. (S3PT-11)
Keep fingers clear of adjusting holes. A sudden movement could cause injury or even
amputate fingers. KEEP CHILDREN AWAY WHEN MAKING ADJUSTMENTS. (SBL-3)
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. (SG-5)

Safety Section 1-11
SAFETY
Your driving vision may be reduced or impaired by the tractor, cab, or implement. Before
driving on public roadways identify any limited vision areas, and make adjustments to your
operating position, mirrors, and the implement transport position so that you can clearly
see the area where you will be traveling, and any traffic that may approach you. Failure to
maintain adequate vision of the public roadway and traffic can result in serious injury or
even death. (STI-10)
SAFETY
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
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death. (SG-14)
Never attempt to lubricate, adjust, or remove material from the Implement while it is in
motion or while tractor engine is running. (SG-20)
Periodically inspect all moving parts for wear and replace when
necessary with authorized service parts. Look for loose fasteners, worn
or broken parts, and leaky or loose fittings. Make sure all pins have
cotter pins and washers. Serious injury may occur from not maintaining
this machine in good working order. (SG-21)
Perform service, repairs and lubrication according to the maintenance section. Ensure the
unit is properly lubricated as specified in the lubrication schedule and all bolts and nuts are
properly torqued. Failure to properly service, repair and maintain this Implement in good
operating condition could cause component failure and possible serious injury or even
death. (SG-35)
Use caution and wear protective gloves when handling sharp objects such as blades,
knives, and other cutting edges. Be alert to worn component surfaces which have sharp
edges. Sharp surfaces can inflict severe laceration injuries if proper hand protection is not
worn. (SG-37)

INTRODUCTION
The HT419H Hay Tedder will help your cut hay dry faster and reduce the “Cut to Bale” time. The six Spring
Steel tines per rotor spread, lift, and fluff the cut hay for better airflow, help it dry faster. Tine height can be
changed with an easy manual adjustment to provide the best performance for your conditions. Designed for
low horsepower requirements, Bush Hog Tedders are a great tool for progressive hay producers. The Bush
Hog hay tedder helps reduce possible damage to plants and potential weather damage to your cut crop by
getting it ready to bale faster. The 540 RPM driveline includes a slip clutch for drive train protection. The
HT419H features hydraulic folding.
The purpose of this manual is to familiarize, instruct, and train. The Assembly Section instructs the owner/
operator in the correct assembly of the tedder using standard and optional equipment.
Careful use and timely service saves extensive repairs and costly down time losses. The Operation and
Maintenance sections of the manual trains the owner/operator how to work the tedder correctly and attend to
appropriate maintenance.

Assembly Section 3-2
ASSEMBLY
General Assembly
Assembly is highly dangerous and must be carried out in strict accordance with the following instructions. We
recommend that qualified personnel perform assembly. It is highly recommended that assembly be carried out
in a flat, solid surface, open area with no people (particularly children) nearby who could be severely be injured
if they were to touch or move any parts of the machine.
Make sure the area around the machine is clear before lowering the wings. Do not lower the
tedder wings when people or pets are near the rotary tedder or folding mechanism. The
tedder must be attached to the tractor when the wings are folded.
Always wear protective eye goggles and use a magnifying glass or hold a piece of wood on
suspected leaks. Pinhole hydraulic leaks can penetrate the skin. Do not touch.
Support and Wheel Assembly
1. To facilitate the assembly of the wheel supports, it is advised that the machine body be turned upside
down. If you use a different assembly method, keep in mind that once pins (5) and bushings (6) (preassembled by in the shop to guarantee correct assembly and safe handling of the machine) are removed,
the rotor assemblies 1,2,3,4 are free to move from their mountings, causing problems for correct assembly
and for the safety of the operators. USE MAXIMUM CAUTION
2. (Refer to Section A of Asm-HT-0010) Remove pins (5) and bushings (6) (keep in mind the warnings in step
1).
3. To avoid errors in assembly, we have numbered both the wheel supports 1,2,3,4 and the rotor assemblies
1,2,3,4 with decals. Combine the wheel support marked with 1 and so on.
4. Before moving on to the fastening of wheel supports 1,2,3,4 to the respective rotors, make sure that the
position of the holes A,B,C,D of the rotor disc are positioned as shown.
5. (Refer to section B of Asm-HT-0010) Now fasten wheel supports 1,2,3,4 using pins 5 and 7.
6. (Refer to section C of Asm-HT-0010) Attach the large hay guards 7 to wheel supports 1,2,3,4 followed by
wheels 8, small hay guards 9, washers 10 and fasten with nuts 11.
7. Item 5, 4 Spring pins Ø10x55 (0.39” x 2.17”)
8. Item 7, 4 Spring pins Ø6x55 (0.24 x 2.17”)
9. Item 10, 4 Flatwashers Ø17 (0.67”)
10. Item 11, 4 nuts M16Connect the fittings
NOTE: At this point the tine arms could be attached because the machine is in a favorable position, but once
the arms are attached it is more difficult to turn the machine over. If the assembler wishes to attach then at this
stage, See Step “E”

When assembling the implement provide suitable lifting mechanisms and supports to stabilize the partially
assembled implements. This will prevent them from falling and causing damage to the implement or serious
injury. The steps for assembly are illustrated in the following pages. Depending on the experience of the
assemblers and the tools available, it is not necessary that the instructions be followed in the exact order given
here, but the safety precautions described above must always be followed carefully and scrupulously.

ASSEMBLY
STEP 1
To Assemble the Hydraulic Tilt Kit to the Tedder the
manual adjustment link Item 1 must be removed.
ASSEMBLY
NOTE: Keep in mind the DANGER resulting from
the removal of Link 1, because once the machine
no longer has the connection between the drawbar
and the frame, the frame tends to open out. This will
constitute a serious danger.
Stabilize the machine to prevent the machine from
opening out when the connection is broken.
At this point to remove the adjustment Link 1, it is
necessary to remove the pins 2 and 3 on the fork
side and pin 4 and washer 5 on the adjustment
screw.

HAY TEDDER ADJUSTMENTS
ASSEMBLY
Connect the hoses “A” to the tractor hydraulic couplings. Now send the hydraulic oil to the leveling cylinder and
adjust the machine according to your needs.
The attaching of the drawbar 1 to the tractor hitch already brings the machine into an initial position, and
normally this makes it possible to make the adjustments required for the working and transport stages.
Sometimes tractors that have a hitch that is too high or too low may cause the machine adjustment to be
unsatisfactory. If this is the case, take appropriate countermeasures. If the drawbar 1 is hooked to the bar of
the tractor lift, the height can be adjusted at any time and therefore adjustments to the machine are easier.
Normally you have good working conditions when the tines 2 at the front of the machine brush against the
ground, If after the machine has been put in the working position the tines 2 are too far from the ground or dig
too deep into the ground, away from the joint pin 6 so as to allow the movement of the adjustment screw
connected to the lever 3. Now move lever 3 to bring tine 2 so that it brushes against the ground. At this point
bring nut 5 back into contact with joint pin 6 and bushing 4 into contact with nut 5. Before tightening them to
each other, make the adjustments in the next step.

Now, sending oil from the tractor hydraulic circuit, raise the side rotors 1. the correct transport position (or
maneuvering position when in the field) is when tine 2 at the front of the machine and tine 3 at the back are
approximately the same distance from the ground.
NOTE: For reasons of stability, the weight of the machine with regard to wheel axle A must always be
unbalanced with more weight at the front, to avoid having the machine tip backwards when it is detached from
the tractor due to it being heavier at the back. Therefore it must be unbalanced toward the front even if tine 2 is
slightly closer to the ground than tine 3.
When the correct transport position is reached, bring bushing 4 into contact with the front face of cylinder 7,
bring nut 5 into contact with bushing 4 and tighten them together. With this adjustment the machine is ready for
working and transport.

Tractor Safety Devices .................... Slow Moving Vehicle (SMV) emblem, lighting, PTO master shield
Tractor Horsepower ......................... 25 HP Minimum
Front End Weights............................ As needed to maintain 20% weight on front axle
3.1 ROPS and Seat Belt
The tractor must be equipped with a Roll-Over-Protective-Structure (ROPS) (tractor cab or roll-bar) and seat
belt to protect the operator from falling off the tractor, especially during a roll over where the driver could be
crushed and killed. Only operate the tractor with the ROPS in the raised position and seat belt fastened.
Tractor models not equipped with a ROPS and seat belt should have these life saving features installed by an
authorized dealer. OPS-U- 0003
Operate this Equipment only with a Tractor equipped with an approved rollover-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)
3.2 Tractor Horsepower
The power required to operate a implement is determined by the tractor PTO horsepower. For most operating
conditions, the HT419H requires a tractor with at least 25hp. Operating the implement with a tractor that does

3.3 Drawbar - Pull-Type Mower
For pull-type mowers (540 and 1000 RPM)
equipped with an equal-angle driveline, the tractor
drawbar must be positioned at a 14” distance from
the hitch point to the PTO shaft end for proper
operation and minimal wear to the driveline and
tractor.
OPERATION
3.4 Front End Weight
A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end
weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the
front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front
weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005
4. GETTING ON AND OFF THE TRACTOR
Before getting onto the tractor, the operator must read and completely understand the implement and tractor
operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for
a complete explanation. OPS-U- 0007
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)
4.1 Boarding the Tractor
Use both hands and equipped handrails and steps for support when boarding the tractor. Never use control
levers for support when mounting the tractor. Seat yourself in the operator’s seat and secure the seat belt
around you.
Never allow passengers to ride on the tractor or attached equipment. Riders can easily fall off and be seriously
injured or killed from falling off and being ran over. It is the operator’s responsibility to forbid all extra riders at
all times. OPS-U- 0008

Before starting the tractor ensure the following:
• Conduct all pre-start operation inspection and service according to the tractor operator’s manual.
• Make sure all guards, shields, and other safety devices are securely in place.
• The parking brake is on.
• The PTO control lever is disengaged.
• The 3-point hitch control lever is in the lowered position.
• The hydraulic remote control levers are in the neutral position.
• The tractor transmission levers are in park or neutral.
Refer to the tractor owner’s manual for tractor starting procedures. Only start the tractor while seated and
belted in the tractor operator’s seat. Never bypass the ignition switch by short circuiting the starter solenoid.
After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden
and unexpected tractor movement. OPS-U-0028
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
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)
6. CONNECTING THE HAY TEDDER TO THE TRACTOR
Use extreme caution when connecting the hay tedder to the tractor. The hay tedder should be securely resting
at ground level or setting on blocks. Keep hands and feet from under the hay tedder and clear of pinch points
between the tractor hitch arms and lift side rotors. OPS-HT-0011

OPERATION
6.1 Attaching the Hay Tedder
The attachment of pull-type machine to the tractor is very simple, as it is only necessary to
couple the drawbar 5 to the tractor hitch using a pin of appropriate size, strength and shape.
Always use extreme care when reversing the tractor towards the machine.
Once the machine is hitched to the tractor, the parking stand 6 must be raised from the
parking position. To do this, remove clip 8 and pin 7, and rotate the parking stand so that it is
parallel with the drawbar 5. Fasten into the new position using pin 7 and clip 8. At this point
quick-release coupling 9 should be attached to the tractor coupling 10. Fasten rope 11 to
lever 12.

Operation Section 4-8
OPERATION
6.2 Safety Tow Chain
If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the
gross weight of the mower must be connected between the tractor and mower. This will help control the
implement in the event the tongue becomes disconnected from the drawbar. Make sure the chain is attached
to a secure location on the tractor and not to an intermediate support.
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death. (SG-14)
7. DRIVELINE ATTACHMENT
The driveline yoke and tractor PTO shaft must be
dirt free and greased for attachment.
To connect the tedder driveline to the tractor PTO
output shaft, pull the driveline yoke collar back and
align the grooves and splines of the yoke with those
of the PTO shaft. Push the driveline yoke onto the
PTO shaft, release the locking collar, and position
the yoke until the locking collar balls are seated
onto the PTO shaft. Push and pull the driveline
back and forth several times to ensure a secure
attachment. OPS-HT-0003

Operation Section 4-9
OPERATION
After connecting both ends of the safety chain, drive the tractor to the right and left to check for proper chain
length. Adjust length as necessary and allow only enough slack in the chain to make a maximum turn in both
directions. When not in use, store the safety chain to protect it from mud or standing water by wrapping the
chain around the tongue. Replace the safety chain if one or more links or end fittings are broken, stretched or
otherwise damaged or deformed. OPS-U-0039
OPERATION
7.1 Driveline Length Check
OPERATION
When fitting the hay tedder to the tractor, the driveline must be inspected to ensure that it is connected
correctly both at the tractor end and at the implements end. If a safety system is provided, this should be fitted
to the machine end, not to the tractor end.
During both transport and use, avoid conditions
where the Driveline transmission shaft is extended
to the maximum. In all working conditions, the
telescopic tubes must overlap by at least 1/3 of their
length refer to Image OP-224.
Conversely, when the driveline shaft is contracted
to the maximum, there should still be a gap of
approximately 2” (50 mm) refer to Image OP-225
Take particular care when connecting the two
Driveline shaft end forks and make sure that they
are fully secured. This is achieved by inserting the
safety pins and bolts (1) in the special slots (2) on
the power takeoff shafts on both the tractor and
implement ends. Refer To Image OP-226.

9. 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
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.
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)

Operation Section 4-15
OPERATION
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)
OPERATION
9.1 Starting the Tractor
OPERATION
The procedure to start the tractor is model specific.
Refer to the tractor operator’s manual for starting
procedures for your particular tractor. Consult an
authorized dealer if the starting procedure is
unclear. Ensure the 3-point control lever is in the
lowered position and the PTO is disengaged before
starting the tractor. OPS-U-0033
9.2 Brake and Differential Lock Setting
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. OPSU- 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.

Operation Section 4-16
OPERATION
9.3 Driving the Tractor and Hay Tedder
Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the
tractor and implement. Moving slowly at first will also prevent the tractor from rearing up and loss of steering
control. The tractor should never be operated at speeds that cannot be safely handled or which will prevent
the operator from stopping quickly during an emergency. If the power steering or engine ceases operating,
stop the tractor immediately as the tractor will be difficult to control.
To avoid overturns, drive the tractor with care and at safe speeds, especially when operating over rough
ground, crossing ditches or slopes, and turning corners. Tractor wheel tread spacing should be increased
when working on inclines or rough ground to reduce the possibility of tipping.
Use extreme caution when operating on steep slopes. Keep the tractor in a low gear when going downhill.
DO NOT coast or free-wheel downhill. OPS-HT-0037_A
10. OPERATING THE TRACTOR AND IMPLEMENT
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
HT419H 03/19

Operation Section 4-17
OPERATION
Perform turns with the tractor and implment at slow speeds to determine how the tractor with an attached
implement handles a turn. Determine the safe speed to maintain proper control of the tractor when making
turns. When turning with a towed implement, the overall working length of the unit is increased. Allow
additional clearance for the implement when turning.
OPERATION
10.1 Operating the Hay Tedder In Field (Hydraulic Fold)
OPERATION
To lower the side arms 1 & 2 of the PT419H hydraulic fold, move the distributor lever 3 so as to send fluid
through hose 4 & 5 to cylinders 6 & 7, which will close completely, pulling rope 8 at the same time as when
moving distributor lever 3, thus making it possible to release catch 9 from pin 10 (RH and LH side). Then
moving the distributor lever 3 so as to lower side arms 1 & 2 down to the ground. (Cylinders 1 & 2 are single
acting, so the side arms 1&2 lower by their own weight, and therefore this operation must be carried out in a
suitable area.) OPS-HT-0046_F
10.2 Adjustment for Correct Working Position
These machines are very easily adjusted. For best operation, the tines 1 on the front side of the machine
should brush the ground. To obtain this, turn the adjustment crank 2.
HT419H 03/19

Operation Section 4-18
OPERATION
10.3 PTO RPM and Ground Speed
Ground speed will depend upon the height, type, and density of vegetation. Recommended speed for efficient
performance is 5 mph. Operate the implement at its 350-450 PTO RPM (540 MAX) rated speed to maintain
good 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 into use. If it becomes necessary to temporarily regulate engine speed,
increase or decrease the throttle gradually.
10.4 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 350-450 RPM (540 MAX).
If you hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the

OPERATION
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 conditions increase, the ground speed should be decreased by selecting a lower gear to
maintain the proper operating PTO speed. OPS-HT-0025
OPERATION
10.5 Shutting Down the Implement
OPERATION
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-HT- 0016_A
11. DISCONNECTING THE HAY TEDDER FROM THE TRACTOR
Before disconnecting the hay tedder, the PTO must be disengaged and all movement must cease. Move the
hay tedder to a level storage location and lower the unit to the ground. If the hay tedder is not resting securely
on the ground, block the hay tedder up securely before attempting to disconnect it from the tractor.
Use extreme care to keep feet and hands from under the hay tedder and clear of any pinch points. OPS-HT0051
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)

13. TRANSPORTING THE TRACTOR AND IMPLEMENT
OPERATION
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
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
13.1 Transport Instructions for Hydraulic Fold
Before transporting, the side arms 1 & 2 must be raised. To do this move the distributor lever 3, sending fluid
through hoses 4 & 5 to cylinders 6 & 7, which will close, lifting the side arms 1 & 2. Before proceeding with

appear as show on Fig. Op-276.
Use extreme caution and avoid hard applications of
the tractor brakes when towing heavy loads at road
speeds. Never tow the implement at speeds
greater than 20 MPH (32 kph). OPS-U- 0018
13.2 Transporting on Public Roadways
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
Only tow the Implement behind a properly sized and equipped Tractor
which exceeds the weight of the Implement by at least 20%. DO NOT
tow the Implement behind a truck or other type of vehicle. Never tow the
Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH. (STI-06)

Operation Section 4-23
OPERATION
Before transporting the tractor on a public roadway
or boarding a trailer for transport, the tractor brake
pedals should be locked together. Locking the
pedals ensures that both wheels brake
simultaneously while stopping, especially when
making an emergency stop.
OPERATION
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
OPERATION
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 lighting on
older tractor models. OPS-U- 0021

the tractor. In an emergency with the machine still connected to the tractor, turn engine off, apply parking
brake, disengage the power takeoff, remove ignition key and wait for all motion to come to a complete stop.
MAINTENANCE
Regular maintenance and proper operation are the basic essentials for a long-term efficiency and safe
operation of the machine.
All maintenance should be carried out in an area having the proper equipment readily available and in good
condition. This area needs to be always clean and dry and must have enough surrounding space to facilitate
operations. Any work must be carried out by a trained person. Contact the dealer nearest you. Respect the
warnings and procedures for maintenance and technical assistance given in this manual.
Do not use pertrol, solvents or other flammable liquids as detergents. Use commercial non-flammable and non
toxic solvents, authorized by competent bodies.
Do not use compressed air or water at high pressure to clean the machine. If this is unavailable, then wear
goggles with side protection and limit the pressure as much as possible. When the work is finished, and with
the machine disconnected from the tractor, inspect the check the machine completely.
Never attempt to lubricate, adjust, or remove material from the Implement while it is in
motion or while tractor engine is running. (SG-20)
Relieve hydraulic pressure prior to doing any maintenance or repair work
on the Implement. Place the Implement on the ground or securely
blocked up, disengage the PTO, and turn off the tractor engine. Push
and pull the Remote Cylinder lever in and out several times prior to
starting any maintenance or repair work. (S3PT-09)
Periodically inspect all moving parts for wear and replace when
necessary with authorized service parts. Look for loose fasteners, worn

NOTE A: Complete lubrication of Gearbox 1
The complete lubrication of gearbox 1 is done the first time at the manufacturers plant, after which it must be
topped off periodically, as according to the lubrication chart. A complete change or fill is necessary only for the
replacement and /or repairing of the entire gearbox or internal parts. In this case, it is necessary to: remove
caps H-K and inject the grease, using grease pump W, into hole T until the grease comes out of hole K. Then
screw caps H-K back into place on center gearbox 1. Use Multi-Purpose Gear Oil.
MAINTENANCE
Periodic checking and topping up of central Gearbox 1:
Every 100 hours of working time, check and top off central gearbox 1. It is a good practice, however, t check
the condition and quantity of grease after all long periods of inactivity, especially when starting to work again
after the winter break. To top off the grease in central gearbox 1 it is necessary to: remove caps H-K and inject
the proper amount of grease into hole J, using grease pump W. Then screw caps of H back into place on
housing 1.
