Changing Row Widths-1730 Machines

IMPORTANT: There should be light contact between ratchet sprocket and ratchet dog assembly. Be certain ratchet sprocket turns freely after moving wheel.

Be certain drive chain aligns properly with ratchet sprocket on countershaft. Loosen sprocket set screws and locate sprocket as needed. Tighten set screws.

NOTE: The drive-gauge wheels are factory set for 38 cm, 51 cm and 56 cm (15 in., 20 in. and 22 in.) row spacing. If other row spacing is desired, move drive-gauge wheels accordingly.

Row widths can be changed on the following machines:

  • 6-Row with 76 cm, 91 cm, 97 cm and 102 cm (30 in., 36 in., 38 in. and 40 in.) row spacings
  • 8-Row with 76 cm, 91 cm, 97 cm and 102 cm (30 in., 36 in., 38 in. and 40 in.) row spacings
  • 9, 11, 13 and 15-Row with 46, 48 and 51 cm (18 in., 19 in. and 20 in.) row spacings

Row widths cannot be changed on the following machines:

  • 9, 11, 13 and 15-Row with 38 cm (15 in.) row spacing
  • 6, 8 and 12-Row with 56 cm (22 in.) row spacing

To change row widths, proceed as follows:

1. Empty hoppers and lower machine to ground.

2. Loosen drive-gauge wheel U-bolts (A), ratchet set screw (B) and planting unit U-bolts (C).

3. Place each inside planting unit so seed disk openers are one-half the desired row width from center of machine frame.

4. Place other units at the desired row width.

5. Tighten U-bolts to specification.

6. Tighten ratchet set screw.

7. Check all drive components for interference. Check planting unit openers to ensure seed tubes and openers are free of dirt or other foreign material.
