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.

The M-Series Curvetine™ (1202 R/L) is drop-forged, and has a lifetime guarantee against bending or breaking.

There are four M-Series Wheels for use with the heavy-duty M-series Hub. Here are a few of the typical configurations.

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 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.

Curvetine™ 1202
Two Curvetines

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

Curvetine™ 1202
& FurrowFlex 1203
One Curvetine, One Rubber

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.

Gaugetine 1204
Two Gaugetines

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.

FurrowFlex 1203
Rubber Closing Wheel

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.

Iron-M 1205
Cast Iron Closing Wheel

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.

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.

Curvetine M-Series Wrench

Slim profiled 1 3/8" wrench for easy installation of modular hubs.

The M-Series hub has wrench flats near the stud, so that it can be tightened from the outside. Unfortunately, to keep the distance to the centerline correct, the space is too narrow to fit a standard wrench.

You could grind a wrench down, but you wont need to... One of these wrenches are included in every order of M-Series Wheels.

Curvetine Wrench

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.

Curvetine Configurations

NOTE: Early 7000 series planters were equip with a stud-style closing wheel attachment. A bolt-through style tail piece, like that of a newer John Deere planter, is necessary for mounting the M-Series Curvetine. Reference John Deere part number AA44266.
