The new M-Series closing system from Dawn features readily adaptable components designed to facilitate ease of use in multiple field conditions. With the new system, operators will have the ability to quickly change from the Curvetine-M wheel, to a heavy-duty, steel rimmed rubber wheel. Fasteners for the wheel are pressed in to allow for a quick switch. The M-Series hub provides a platform for a variety of wheels to accommodate changes in soil and tillage practices.
  
The hub of the M-Series Closer is drop-forged. As with the original Curvetine Closing Wheel, and Dawn Trashwheel row cleaners, the M-Series hub rolls on Timken tapered roller bearings. The hub is re-greasable by using an aluminum, o-ring sealed Supercap. The M-Series hub reduces downtime and part replacement and bolts directly onto most OEM v-style tailpieces.
  
The Curvetine-M Wheel itself is now drop-forged, and Dawn is offering a lifetime guarantee against bending or breaking. The Curvetine chips in the sidewall and promotes seed-to-soil contact and uniform emergence without the need for firmers or drag-chains.
