Introduction

SAFETY SUGGESTIONS
Federal law requires you to explain the safety and operating instructions furnished with this machine
to all employees before they are allowed to operate the machine. These must be repeated to the
employees at the beginning of each season. Be sure to observe and follow the instructions for the
safety of anyone operating or near the machine.
Investigation has shown that nearly 1/3 of all farm accidents are caused by careless use of machin-
ery. You can do your part in improving safety by observing the following suggestions. Insist that all
people working with you or for you abide by them.
1. Do not stand between the tractor and implement when attaching or detaching implement
unless both are not moving.
2. Before applying pressure to the system, be sure all connections are tight and that hydraulic
lines and hoses are not damaged. Check the system again while cycling.
3. Escaping fluid under pressure can be nearly invisible and have enough force to penetrate the
skin causing serious injury. Use a piece of cardboard or wood, rather than hands, to search
for suspected leaks. If injured by fluid, see a doctor at once.
4. Do not make adjustments or lubricate machine while it is in motion.
5. Do not allow anyone to ride on tractor or machine.
6. Always use transport locks while transporting the machine.
7. Do not transport at speeds over 15 mph.
8. Avoid sudden stops or turns when transporting because the weight of machine may cause
operator to lose control of tractor. Use a tractor heavier than the machine. Do not allow
tractor drawbar to swing when in transport.
9. Use caution when towing behind articulated steering tractors; fast or sharp turns may cause
the machine to shift sideways.
10. When transporting the machine on a road or highway, use adequate warning symbols,
reflectors, lights, and slow moving vehicle signs as required. Use a safety chain.
11. Block machine so it will not roll when unhitched from tractor.
12. Relieve pressure in hydraulic lines before uncoupling hydraulic hoses from tractor. On most
tractors this can be done by operating valves after engine is stopped.
13. Securely block machine when working on or under it to prevent injury in case of hydraulic
failure or inadvertent lowering by another person.
14. Lower machine to ground when not in use.
15. Do not fold or unfold wings without first bleeding all air from the hydraulic circuit.
16. Know the height of your machine in the folded position, do not fold the wings under low power
lines or other obstructions.
17. Fold wings on as level a surface as possible.

799rev3-20-05 Page 4

The wings of the HFC Cultivator must not be raised by any other method than
using properly bled hydraulic cylinders provided with the machine.
If the wings have been raised by another method, and the cylinders are not filled with
oil, the unfolding sequence becomes extremely dangerous. Also, wings raised
by other methods could fall when transporting a machine over uneven terrain.
Do not remove the cylinder pins or service the cylinders unless the wings are un-
folded and supported.

chine to warn of hazards. “The warnings found on the signs are for your own personal safety and that
of those around you.” OBSERVE THESE WARNINGS!
There are three levels of hazard intensity that appear with the safety alert symbol on safety decals:
DANGER, WARNING, and CAUTION. Hazard intensity is defined as follows:
DANGER - Immediate hazards which WILL result in severe personal injury or death.
WARNING - Hazards or unsafe practices which COULD result in severe personal
injury or death.
CAUTION - A reminder of safety practices, or an alert to unsafe practices which could
result in personal injury.
Keep these signs clean so they can be observed readily. Wash with soap and water or cleaning solu-
tion as required.

DECAL LOCATIONS

PRE-OPERATING CHECKS
Hydraulic cylinders
Before raising or lowering the wings, be sure that the wing lift cylinders
are properly bled (all air is removed from the hydraulic circuit). Improperly
bled cylinders will permit the wings to free-fall, possibly causing injury to
the operator and damage to the machine.
Bleed the system by removing the rod end pins which connect the cylinder to the wing and
fully extend and fully retract the cylinders three or four times. Reconnect the cylinder rod
ends to the wings.
Check to make sure that flow restrictors have been installed in the wing lift circuits. These
are screwed into the rod end port of all 4 wing lift cylinders. These restrictors control the
passage of oil to and from the wing lift cylinders and prevent the wings from falling too rap-
idly.
Tractor hydraulic level
The wing lift and depth control cylinders are shipped from the factory without oil in them.
All 8 cylinders must be charged with oil, they will use approximately 6 gallons of oil. Check
your tractor hydraulic level to avoid any damage to the system.
Three point hitch position
Before moving the implement, be sure the three point lift arms of the tractor have been
raised to avoid damaging the tongue on the cultivator when making sharp turns.
Jack
Make sure the jack has been moved to its storage position on the drawbar and pinned in
place.
Level adjust
Because this field cultivator has different diameter tires on the center section than it does on the
wings, it is important to follow these leveling instructions exactly.
The depth adjust rods for the center section must be adjusted equally to prevent damage to the
center axle.
1. Unfold the wings of the field cultivator. Be sure to hold the control lever to the extend
position until the wing lift cylinders are completely extended.
2. Operate the hydraulic control lever for the wheel cylinders to the extend position and
hold it there until there is no movement in any of the wheel cylinders.
3. Measure the pin center distances of the wheel cylinders(See figure 3):
If they are all the same, (approximately 28 1/4”), proceed to step #6.
If the pin centers differ, retract the cylinders and measure the pin center. If they are not
all the same length, (approximately 20 1/4”), adjust the rod end clevis as necessary so
that all cylinders are the same length. Make sure that the rod end thread engages the
clevis completely, and that the locking bolt on the cylinder clevis is tightened.

4. Extend the cylinders and hold the control lever in the extend position until there is no
motion in any of the cylinders. Check the pin center distances. If they are not all
approximately 28 1/4”, retract the cylinders and disconnect the pins from the wheel arms
and the cylinder anchors. Bleed any air from the hydraulic circuit by positioning all the
wheel cylinders with the rod ends higher than the rest of the cylinder and then extending
and retracting the cylinders at least three times. At the end of each extend stroke, hold
the hydraulic control lever at least 30 seconds.
5. Retract the cylinder rods, and reconnect the cylinders to the cylinder anchors and
wheel arms.
6. Use the hydraulic lever to move the wheels so that the tooth points of the CENTER
SECTION are just barely above the ground line.

7. If the point to ground distance is not the same in the front
as in the rear, level the machine by adjusting the drawbar leveling turnbuckle.
8. Now adjust each wing cylinder depth adjust rod so that the tooth points of each wing
section are the same distance from the ground as those on the center section.
Note: You will have to lower the machine onto the tooth points to be able to turn the adjust
screw. Each turn changes the point position by approximately 5/16 inch (three
turns equals one inch.)
Page 10 4K598
799rev3-20-05

9. After each adjustment, completely raise the field cultivator, hold the hydraulic control in he
extend position, and then lower the machine until the tooth points are just barely off the
ground.
Note: During the leveling procedure, the front gage wheel is not supporting the frame
and the outside front teeth of the cultivator wing may touch the ground first.
This will be eliminated in the operation, by adjusting the front gage wheel.
Note: The machine is designed so that the rear will raise slightly more than the front.
This is done so that if you have drags mounted to the cultivator, there will be
adequate ground clearance in transport. Therefore the cultivator will not be exactly
level in the transport position.
Page 11 4K598
799rev3-20-05

OPERATING INSTRUCTIONS
DO NOT allow others on or near the tractor and the machine when operating
or preparing to operate the machine.
Prepare the machine for transport
1. Extend the transport wheel cylinders completely. These are series cylinders and are de-
signed to raise the machine evenly. The cylinders will rephase or equalize at the end of their
stroke. Simply continue to hold the hydraulic control lever of the tractor in the extend posi-
tion until all cylinders in the system are completely extended. Do this occasionally during
operation at the end of the rows to make sure that the cylinders remain in phase.
2. With the machine in the up or transport position, raise the wings to folded position.
Know the folded height of your field cultivator and any attachments. Be sure
that you are not under any electrical lines or any other obstruction that could
cause injury to the operator or damage to the equipment.
3. Use the transport locks to lock the machine in the transport position.
Maximum road speed is 15 MPH under good conditions. Do not tow the
machine at a speed at which the operator loses control of his vehicle.
Do not tow the cultivator with a vehicle that is lighter than the cultivator.
It is the responsibility of the owner/operator to comply with all applicable laws regarding slow
moving vehicle signs, warning lights, reflectors, and safety chains.
Safety Chain
Use of a safety chain is recommended if the machine is towed on a public road or highway. Total
weight of towed machine must not exceed chain capacity as shown on the chain’s identification tag.
A safety chain is included with the cultivator.
Slack in the chain should be only enough to permit turning. Distance from hitch pin to attachment
point or intermediate support should not exceed 9”.
CAUTION If two or more machines are pulled in tandem, a larger chain may be
required. Chain capacity must be greater than the total weight of towed
implements. A second chain should be used between each implement.
CAUTION Replace chain if one or more links are broken, stretched, or otherwise
damaged or deformed.
Keep attaching hardware fastened securely.
If bolts are replaced, be sure to use grade 5 or higher.
If you have any questions regarding the safety chain call your Brillion dealer.

Prepare the machine for field operation
1. Raise the machine fully on its transport wheels.
2. Flip the transport locks on both center axle lift cylinders into their storage positions.
3. Lower the wings by extending the wing lift cylinders. Make sure that the cylinders are
extended completely; this will allow the wings to float down to follow the contour of the
ground.
Operating depth adjustment
1. With the machine leveled, the transport locks rotated down, and the wings unfolded, set the
approximate working depth by adjusting the cylinder anchor brace rods. The scales on
the anchor adjust rods are used to make sure that the brace rods are set equally. The wing
operating depth can be adjusted independently of the center section by changing the anchor
rod length as required. Shortening the brace tube raises the wing, decreasing the operating
depth. Lengthening the brace tube increases operating depth. One turn of the adjust tube
increases or decreases operating depth by approximately 5/16” (3 turns for 1 inch of depth).
Note: Lower the machine onto the shanks to turn the adjust tubes.
Important: Adjust both anchor braces on the center section equally. Unequal length braces will
put a strain on the center axle, center frames, and on hydraulic cylinders.

2. Level the machine front to rear by adjusting the leveling linkage as required. Lengthening the link-
age raises the front, shortening the linkage lowers the front.
NOTE: In operation, the adjustment of wing gage wheels will probably be different than the center
section. This is due to the difference in tires and also because the wheels of the center section are
probably following in the tractor tire tracks. The best way to check if the machine is level, is to
make all the adjustments with the tooth points just above ground on a level surface. Then
lower the machine into the ground and drive forward several feet. Now, stop, slowly raise
the machine and watch as the sweeps of the field cultivator come out of the ground. They
should all come out at the same time. If the front of the machine comes out of the ground
before the rear, lower the front of the cultivator. If the wings come out of the ground before
the center, set the wings to operate deeper and vice versa.
3. After the machine has been leveled in the operating position, operate a few feet and verify
the operating depth. The depth can now be changed by adjusting all brace rod tubes equally.

MAINTENANCE
Fasteners
After a few hours use, check entire machine and tighten any loose nuts or bolts. Daily or
periodic checks should be made thereafter.
Shanks
After 5 hours of operation, and every 50 hours thereafter, check to make sure that the shank
pivot bolts are tight. Loose pivot bolts will permit the bushing to rotate in the spring holder
causing the holes to wear, resulting in sloppy shank support.
Lubrication
Lubricate your field cultivator at the locations shown in figure 9. The number in the lubrica-
tion symbol indicates the hourly interval between greasing.
Always lubricate your field cultivator before taking it to the field for the first time.
Lower the implement unto the shanks before greasing.
Replace any missing fittings and clean all fittings before greasing.
Wheel bearings and walking beam bearings should be repacked annually. Follow the disas-
sembly and reassembly procedures below in figure 8 when repacking these bearings.
When the machine is not to be used for some time, exposed portions of the cylinder rods
should be cleaned and covered with a thick coat of grease. This will prevent corrosion which
will damage seals.
