M-Series Closing Wheels
updated: 2021
M-Series
The M-Series allows you to cater to the demands of local field conditions. Quickly change from our proven curved tooth in minimally tilled ground, to heavy-duty rubber in conventionally tilled ground
Curvetine
• Promotes seed to soil contact and uniform emergence
•
Eliminate side wall compaction
• Modular to adjust for soil type
and/or changing tillage practices
• Curvetine® is forged to last
for many years of service
• The Curvetine tooth is wide like a
rubber wheel to produce seed to soil contact but the intermittent
contact of the teeth chips in the sidewall
M-Series Modular Hub
400156 RH or LH
Like the original Curvetine Closing Wheel, and Dawn Trashwheel Row
Cleaners, the M-Series hub rolls on American made Timken™ tapered
roller bearings.
The hub is regreasable (no disassembly
required) using our ruggedized aluminum, o-ring sealed Supercap. The
M-Series hub greatly reduces down-time and part replacement due to
its drop-forged construction, and bolts directly onto most OEM
v-style tailpieces with minimal installation time.
The majority of the cost of the M-Series wheels is in the hubs, not
the wheels, which allows them to be changed back and forth for a
reasonable cost.
M-Series Planter Configurations
There are four M-Series Wheels for use with the heavy-duty M-series Hub. Here are a few of the typical configurations.
Two Curvetines
Curvetine™ 1202
The Curvetine™ M-Series Closing System has unique curved teeth to
chip-in side wall compaction without ejecting soil from the seed
zone.
Unlike straight tooth wheels, the curved tooth
eases out of the seed zone while providing consistent seed-to-soil
contact for uniform emergence.
We do not recommend
running drag-chains or seed firmers with the Curvetine closing
wheel, the wheel creates an ideal seed-bed in most conditions
without any additional equipment.
One Curvetine, One Rubber
Curvetine™ 1202 & FurrowFlex 1203
For customers who will be running in mellow, or heavily worked
ground the Curvetine™ may be used with either your standard rubber
closer, or if your planter is equipped with two M-Series hubs, you
can swap out your Curvetine for the FurrowFlex steel rimmed rubber
wheel.
Typically we recommend you run the Curvetine in
the front bolt-hole and the rubber wheel in the rear bolt-hole of
the tail piece.
Rubber Closing Wheel
FurrowFlex 1203
The FurrowFlex rubber wheel for the M-Series modular hub system
combines a heavy duty metal rim with a very flexible rubber tire.
The custom designed rubber profile is flexible to
deform and shed sticky soil. It is constructed from the highest
quality rubber compounds available.
This tire/wheel is
also a good combination for growers who want to use a rubber wheel
but are looking for a heavier duty bearing and hub than the OEM
product.
Two Gaugetines
Gaugetine 1204
The model 1204 Gaugetine combines the crumbling action of the
Curvetine with a depth gauging shoulder.
This wheel
will be used in shallow planting situations where the shoulder
limits how deep the wheel can penetrate the ground. This wheel is
a good fit in heavier ground, conventional tillage or shallow seed
depths such as cotton.
Cast Iron Closing Wheel
Iron-M 1205
Occasionally your operation may benefit from the use of a cast
iron closing wheel.
Dawn now offers a slightly lighter
cast iron closer equivalent to the John Deere cast iron closer
that you can bolt to your M-Series hub.
The weight
difference allows you to use more range on your tailpiece down
force spring. It is much easier to add spring weight, than to take
wheel weight away.
102151
1/2 Rate Down-Pressure Spring for your Planter Tailpiece!
If you like the action of two Curvetines, but have difficulty setting
the spring rate to a light enough setting, we strongly recommend our
half-rate spring.
This spring will allow you to use the
full range of settings on your tail-piece. It also makes it possible
to run two Curvetines per row in a much wider range of conditions.
*For all new White and 9000 series planters, we recommend
the half rate spring.
M-Series Drill Configurations
There are four M-Series Wheels for use with the heavy-duty M-series Hub. Here are a few of the typical configurations.
Closing Wheel
Gaugetine 1230
The model 1230 Gaugetine is intended for applications on single
disk drills to eliminate side wall compaction.
For use
on John Deere **60 and **90 series drill units with bearings in
the arm.
Closing Wheel
Gaugetine 1240
Gaugetine closing wheel for John Deere Drills with bearings in the closing wheel (i.e. 50 series)
Closing Wheel
Gaugetine 1245
Gaugetine closing wheel for Case SDX drills
