attention of the operator. Do not use headphones to
listen to the radio when traveling on roads.
USE SAFETY LIGHTS AND ACCESSORIES
Slow moving vehicles, tractors, trailed or suspend-
ed equipment can pose a risk when being transport-
ed or towed on a highway because they are difficult
to see, especially at night. Avoid injury or even
death that can result from a collision with other
vehicles.
It is recommended to use safety lights and accesso-
ries when driving on public roads. To improve
visibility, use all lights available on the tractor. The
additional installation of rotating warning lights is

10
SAFETY RULES

TRACTOR PREPARATION
REQUIRED POWER
For recommended tractor power refer to the
specifications table in the specifications section.
(page 06).
REAR COUNTERWEIGHTS
When additional weight is required or instead of
liquid weight, cast iron counterweights can be
bolted to the rear tires.
Use rear counterweights to stabilize the tractor on
uneven terrain or hillsides, and to eliminate exces-
sive tire slippage. Counterweights should not be
added to the point of completely eliminating
skidding.
Tractor tires should be inflated to the pressure
recommended in your operator's manual.
FRONT COUNTERWEIGHTS
Add weight, if necessary, to the front of the tractor
for stability.
To improve tractor handling, remove front weights
when they are not needed.
Refer to the tractor operator's manual for adding
front weight.
Observe rear wheel tracks. When the tractor is
operating at optimum load, the ground between the
tire treads should be broken or sectioned (A).
If too much counterweight has been added, the
track marks will be crisp and clear (B).
If too little counterweight has been added, the track
marks will be almost blurred (C). Refer to the tractor
operator's manual.

SUBSOILER HITCHING TO TRACTOR
CAUTION: To avoid personal injury or machine
damage when an implement is hitched, place the
tractor transmission in the park position and check
for interference along the hitch.
Do not stand between the tractor and implement.
The sides of the tractor and implement are the only
access for connecting and disconnecting the hitch
points.
Slowly back the tractor into the Subsoiler, making
sure that the hitch points are aligned.
2. Place the transmission in park position.
3. Shut off the tractor engine.
4. Remove the pins from the Subsoiler side and
center hitches.
5. Align the tractor lift arms with the side hitches and
install the bolts.
6. Hitch the third point arm to the hitch plates and
install the bolt.
7. Start the tractor engine.
8. Slowly move the swing axle position control lever
to raise the implement. Check that there is no
difference.
9. Lower the implement to ground level, place the
transmission in park position and proceed to level
the Subsoiler by adjusting both lift arms to the same
length.
10. Finally adjust the third point arm (lengthen or
shorten) as required to achieve longitudinal leveling
of the Subsoiler.
OPERATION
TRANSPORTING SUBSOIL SAFELY
CAUTION: The Subsoiler should not be
transported at a speed greater than 10 mph, in
order to prevent accidents.
Higher speeds may result in loss of control of the
tractor if any of the outside rudders contact any
uneven ground surface.
Always drive at a speed that allows you to have
adequate steering and brake control.
When transporting the Subsoiler on a road or
highway at night or during the day, use lights and
devices for adequate warning to operators of other
vehicles. In this regard, check your local govern-
ment regulations for proper use. A machine that is
not properly illuminated could cause an accident,
which could result in serious injury or death to you
or others.
1. To obtain more lift from the Underlayment when
transporting, shorten the lift joints and center arm to
their minimum length, or hook the lift arms into the
lower holes in the hitch plates.
2. Place in transport position (upward) the rudders.

13
LATERAL SUBSOILER LEVELING
Lateral leveling is controlled by the tractor lift arms.
Make sure that the main body of the Subsoiler is
parallel to the ground so that all tiller arms rotate to
the same depth.
After the tiller arms have penetrated the ground and
you have set the working depth, stop the tractor and
stand behind the Subsoiler to confirm that the main
body is parallel to the ground.
If the main body is not parallel to the ground, raise
the implement and adjust the tractor hitch arms until
the Subsoiler is level.
LONGITUDINAL LEVELING OF THE SUBSOILER
Longitudinal leveling is controlled by the tractor's
center hitch arm.
To determine if the Subsoiler is level longitudinally,
observe the main body while working under load.
Make sure that all rudders are at the same level.
It is more efficient to work the Subsoiler when all
shanks are level.
If the main body is not level longitudinally raise the
Subsoiler and adjust it by lengthening or shortening
the third point arm.
OPERATION

14
LUBRICATION
CAUTION: Do not clean, lubricate or adjust the
machine when in motion.
IMPORTANT: The recommended periods are based
on normal operating conditions. In severe or
non-normal conditions, more frequent lubrication will
be necessary.
IMPORTANT: Clean the grease fittings before using
the grease gun. Replace any missing or broken grease
fittings immediately.
Lubricate the lump braker roller bearings before each
day's work. Apply grease until it comes out of the
gasket. Rotate the roller 2 or 3 times.
This process will extend the life of the bearings.
CORRECT USE OF SEAT BELTS
Do not use a seat belt when working with a machine
that is not equipped with a rollover protector.
Transport the Subsoiler at a maximum of 10 mph.
Reduce speed when traveling over rough terrain.
Always drive at a speed that allows you to have
adequate steering and brake control.
GREASE
Choose the most suitable type of grease according to
the NLGI consistency and the temperatures that may
occur in the interval until the next grease change.
You can use greases that meet the following standard:
NLGI consistency classification GC-LB.
Alternative and synthetic lubricants
Conditions in certain geographical areas may require
the use of special lubricants or lubrication techniques
not listed in the operator's manual.
Some lubricants may not be available in the area. In
this case, consult your distributor, who will provide you
with the most up-to-date information and
recommendations.
Lubricant Storage
Your equipment can operate at maximum efficiency
only if you use clean lubricant.
Use clean containers to handle all lubricants and store
them in an area protected from dust and moisture.

FUSIBLE SCREW
The SVH-1 Subsoiler tiller is equipped with a fusible
safety screw (A).
This bolt will break if the tiller accidentally runs into
rocks, logs, roots, etc.
This protects the Subsoil and the tractor from possible
serious damage.
CAUTION: To avoid accidents, do not attempt to
remove a broken fusible link if the tiller is in a horizontal
position (tip up). With extreme caution, place the tiller
in the vertical (normal) position before replacing the
fusible safety plug.
IMPORTANT: The fusible safety bolt (A) must be
replaced with a grade 5 fusible safety bolt, do not use
any other hardness grade. After replacing the fusible
safety bolt, retighten the rudder bolt (B) according to
the bolt tightening specifications table on page 36.
REPLACEMENT OF THE TIPS
The replaceable scarifier tip (A) on the shanks (Shoe)
allows you to replace it with a new one when a tip has
been damaged, broken or worn.
To replace a tip, drive the pinch pin (B) out from
between the tip and the rudder with a 10 mm (3/8") pin
punch. Do not use a tapered punch.
Remove the damaged tip and install a new tip on the
chisel. Place the pinch bolt through the new tip and
shank.
KEEP THE SUBSOILER AVAILABLE
Thoroughly clean the Subsoiler before storing it.
Protect shanks and scarifying tips from corrosion by
applying a light coat of oil or grease.
Apply a good anti-corrosive when storing the Suboiler
for the next season.
After storage: Clean accumulated dust from moving
parts to prevent abrasion and excessive wear.
Inspect the Subsoiler thoroughly. Check for loose parts
and adjust if necessary.
