Move the planter to an area with adequate illumination, and a clear surface beneath for recover of any dropped parts. 2. Unfold the planter, if a folding model. 3. Raise the planter. Raise the row units if a separate operation. Install lift/transport locks. 4. Block tires, or put hitched tractor in Park, set parking brake, and remove key. Tools Required Basic hand tools Screw thread adhesive, such as Loctite Unit Mount Coulter Installation Refer to Figure 2 1. Mount the coulter assembly to the front of the opener unit with 1 2 inch 1 1 2 inch carriage bolts, 1 2 inch lock washers and 1 16 20 2 inch nuts 18. 2. Align the coulter blade so it is centered between the two opener disks and tighten the bolts. 3. With the coulter assembly mounted and tightened the coulter blade should be at or 1 4 inch above the depth of the opener disks. See adjustment on page 5. Crushing Hazard: Prevent frame and.or opener lowering. Coulter installation requires working near raised row units, and perhaps under raised frame-mounted accessories. A lowering or falling frame, wing or row could cause serious injury or death. Sharp Object Hazard: Row unit disk blades may be sharp. Use caution when installing or making adjustments. 18 20 16 Figure 2 Mounting Coulter Assembly 34397 204-141M Table of Contents Appendix 2012-08-27
Great Plains Manufacturing, Inc. Table of Contents Appendix 5 Adjustments The ideal operating depth for coulters is 1 4 inch (6 mm) above opener depth. Although they may have originally been set to this depth, coulter (and opener) blades wear with time, and may need adjusting. Adjusting the coulter depth is accomplished by re-mounting the coulter blade in one of the six mounting holes arranged in a staggered pattern in the coulter bracket. Refer to Figure 3 and Figure 4 Raise unit mount coulter and install cylinder locks before working on coulters. Row unit may be fully lowered or locked up. Do not attempt to move blade when the current or new position causes it to contact the ground during adjustment. Be careful around the front end of row units. Row clear tines and coulter blades may be sharp. To adjust coulter depth: 15 7 1. Dismount row cleaner (if present) to reduce risk of injury. 2. Determine the present opener and coulter depths. Figure 3 25 Series Unit-Mounted Coulter 29124 3. Note which bracket hole the coulter is presently using. 4. Determine which new hole will position the coulter closer to the 1 4 inch-above depth. See the table below. If none, don t move it. 5. Remove the 5 8-11 4 inch bolt, lock washer and nut ( 15 in Figure 3). 6. Move the blade to the new position. Insert the bolt, and tighten on the lock washer and nut. Hole Number Depth of (new) coulter blade relative to (new) opener blades 5 6 3 4 2 1 2 1 inch (25 mm) above 3 5 8 inch (16 mm) above 5 1 4 6 1 4 inch (6 mm) above 0 3 8 inch (9.5 mm) below 3 4 inch (19 mm) below 7. Re-adjust openers, if installed. If a worn coulter cannot be adjusted to satisfactory operating depth, replace coulter blade.
