Martin Spading-Closing wheels move soil toward the seed at planting depth, while lifting and fracturing the surface layer to achieve compaction- free closing of the seed trench in wet, hard, or sod conditions. With soil firmed around the seed from each side and the surface layer loosened, crops emerge sooner and planting can be done at the proper depth, even in wetter conditions, without fear of crushed soil above the seed preventing emergence.

Our Spading-Closing Wheels do not attempt to close the seed trench by a crushing action from the top down. The soil is wedged toward the seed from either side at seeding depth by a pair of Martin Row Cleaner wheels. The ends of the teeth have full bevels cut on them. The beveled sides of the teeth on each wheel are placed toward the row and the narrow edge enters the soil first producing a wedging action. As the teeth on the wheels rotate up out of the soil, a slight lifting and crumbling occurs in the surface layer. The area on either side of the seed and immediately above it is not fractured, and because of the shape and spacing of the teeth on these wheels, wet soil does not bind to them.

Specific Advantages

  • Speeds up warming of the row area
  • Closing wheel arm pressure can be greatly reduced
  • Seed trench is closed in the most severe conditions
  • Seed depth does not have to be raised to insure emergence
  • Soil above the seed is loose and slightly mounded allowing quicker emergence in a compaction-free environment
  • Sidewall compaction is greatly reduced


The Twisted Drag Chain helps to further crumble and level the soil. This helps even out the rate of drying and insures the soil does not dry past seed depth. This is a low cost, low maintenance way to help increase uniform emergence in the drier parts of the field and is a must when using the spading closing wheels in minimum till. By the way, some of our customers still feel the need for some shallow tillage in the spring and the spading closing wheels and drag chain combination do an excellent job in that situation.


Properly designed row cleaners provide a very desirable type of tillage. !e row cleaner teeth continuously engage the soil to the shallow depth of 1″ to 1 1/2″. !is scarifying of the soil’s surface layer makes it easier for the seed openers to open a welldefined “V” but without furrowing out or causing slabbing or fleaking. Eliminating furrows is the key to preventing erosion in the row on slopes and the ponding of water over the row in level areas. Martin Row Cleaners come in two basic types: rigid and floating.


Our floating models have the advantage of always moving residue and lightly tilling the seed zone and leaving no skips or furrowed out places. Floating models fit most popular planters and may be used ahead of most no-till coulters or certain fertilizer openers including our UMO-100 Unit-Mounted Fertilizer Opener.


Kit 1:

Unit set back kit for John Deere 7000 series and Kinze planters. This kit moves the unit back 6” to allow more clearance when installing floating row cleaners around certain no-till coulter configurations.

Kit 2:

Unit set back kit for John Deere 7200 series through to John Deere 1700 series planters. Moves the unit back 6” to allow more clearance when placing floating row cleaners around no-till coulter configurations.


Place fertilizer in soil, not on trash or planter

Our fertilizer opener mounts directly to the planting unit and is compact enough to be used with our C125 Row Cleaners. Because the opener mounts directly to the planter unit, the fertilizer is always precisely the same distance from the seed even when planting on the contour. The lateral spacing from the seed can be 1″, 2″, or 3″, and there are three vertical settings that allow fertilizer to be placed 3/4″ above, even with, or 3/4″ below seed depth. We like the way it consistently places the fertilizer in the ground without splattering it on the planter.
