GENERAL SAFETY
It is essential that you be able to recognize safety signal
words and their associated symbols. Please be alert to
any signs posted on your Dawn Equipment Company products,
and/or in your users manual. Make sure you have read
all safety messages and that you clearly understand the
recommended precautions. If you have any questions
about any Dawn safety sign, or have further questions
about the safety recommendations on this or any other
Dawn product, please contact Dawn Equipment Company
at 800.554.0007.
DANGER - Indicates an imminently hazardous situation
that, if not avoided, will result in serious injury or death,
and/or property damage
WARNING - Indicates a potentially hazardous situation
that, if not avoided, will result in serious injury or death,
and/or property damage.
CAUTION - Indicates a potentially hazardous situation
that, if not avoided, may result in minor or moderate
injury, and/or property damage.
REPORTING AN EMERGENCY
Ensure that you have access to a radio or a mobile phone
when operating or repairing farm machinery. Working with
a partner whenever possible significantly increases the
chances of receiving timely emergency care should one
party become severely injured, and/or incapacitated.
MAINTENANCE AND UPKEEP
For safety reasons, it is important to keep your implements
in proper working order. Unauthorized modifications to
Dawn Equipment Company products may compromise the
efficiency and/or safe operation of the product and will void
any and all warranties through Dawn Equipment Company.
Please read your manual before attempting any repair work
to your Dawn tool. If you need to work on your Dawn tool,
make sure to support it before partially or fully removing
it from the attachment points. Do not adjust your Dawn
tools while they are moving.
PROTECTIVE CLOTHING
Wearing proper attire when working on agricultural equipment
is a critical safety precaution. Loose clothing or accessories
may become entangled in moving parts causing serious injury
or death.
SAFETY INFORMATION
SAFETY GLASSES/GOGGLES
If you will be using hazardous
chemicals, or are striking, cutting
or grinding metal make sure you
are wearing eye protection.
EARPLUGS / SOUND MUFFLERS
When working around equipment that
generates high amplitude sound (ie
dryers, vacuums, etc.) ear protection
is strongly recommended.
RESPIRATOR MASK
Carefully read all safety
information associated with
any chemicals you will be
handling. Use a respirator
mask when using hazardous
chemicals, (ie Insecticides,
NH3, etc.)
WORK GLOVES
If working around machinery
with sharp edges, or rough metal
surfaces, work gloves may prevent
a few stitches. Work gloves are
inexpensive, and are really worth
the investment.
STEEL-TOED BOOTS
A good pair of steel-toed boots
can safe your toes. Avoid
an unfortunate accident, and
protect your feet.
FIRST AID KIT
In order to minimize the risk of
infection, every shop and tractor
should have a complete first aid
kit.

CURVETINE PLACEMENT - STAGGERING WHEELS
Most major planter row unit manufacturers incorporate a
two-hole tailpiece design for staggering the closing wheels.
When running one Curvetine and one rubber wheel, it is
recommended to have the Curvetine in the front hole closest
to the planter with the rubber wheel in the rear hole. This
is a good idea for shallow planting depth and prevents the
Curvetine from becoming too aggressive. If more aggressive
action is needed, you may reverse the orientation and run
the Curvetine in the rear hole furthest from the planter with
the rubber wheel in the leading hole. With either setting, it
is important to be mindful of your tailpiece down-pressure.
The first (lightest pressure) notch is a good place to start.
CLOSING WHEEL SPACING
As a general rule, the distance between wheels (mea-
sured center-to-center) should match your desired plant-
ing depth. Each Curvetine order contains multiple washers
as well as a triangular hub spacer, these will allow you to
adjust your closing wheel spacing to match your planting
depth. The deeper your seed is being placed, the further
apart the closing wheels need to be. You may need to adjust
your wheel spacing when changing planting depth.
PRODUCT INTRODUCTION
Left-hand threads Right-hand threads
for left-hand hub for right-hand hub
HUB ORIENTATION
Hubs are handed! Due to the special hub-shaft threading,
a left-handed hub can only be installed on the left-hand
side of the tailpiece, and a right-handed hub can only be
installed on the right-hand side of the tailpiece.
Left-hand hubs are indentied by an “L” marked on the hub
shafts. The right-hand hub shaft will show nothing on it.
WHEEL ORIENTATION
Curvetines are directional! Due to the modular design
of the M-Series Curvetine, each wheel is symmetrical and
can be mounted to either the right-hand or left-handed
modular hub. Install Curvetines according to the arrow
indicating direction of forward travel.
CARE AND MAINTENANCE
Use Mobil XP222 or similar to grease hubs yearly or every
100 acres/row, whichever comes first. In extremely dusty
environments and when liquid fertilizer is being applied
with the planter, it may be necessary to grease hubs daily.
Grease to purge; it is not possible to over-grease hubs.
Remove excess grease.
The distance between your
closing wheels should be
about the same as your
planting depth. Make sure
wheels sit on the OUTSIDE
of the furrow.
