INSTALLATION

1. Assembly 3/8 x 2-1/2” roll pin into hole closest to end of 1-1/2” diameter shank, leaving

approximately equal amount protruding out each side. Note: offset shanks require that you perform step 2 first then step 1.

2. Insert lock collar into pivot casting and slide shank up through casting and lock collar.

If you wish to lock coulter from pivoting, slide roll pin into slots in casting. If you wish to let coulter pivot, do not align roll pin with casting slots, but slide shank up till roll pin contacts casting surface. Install and tighten 5/8 x 1” setscrew in lock collar to 110 ft. lb. torque maximum.

3. Mount 17” blade loosely to hub using four 1/2 x 1-1/2” carriage bolts, lock washers and

nuts.

4. Mount fertilizer knife and spacer block to rear support arm using two 1/2 bolts lock

nuts. Place shims between 2995-309 – Spacer Block and support arm as required to align knife point with blade.

5. Center blade on hub by rotating blade and watching clearance between knife and

blade. Slide blade on hub as required until clearance varies no more than 1/8” when blade is rotated one complete revolution. Tighten four 1/2” nuts. If blade-wobble is excessive, check for burrs on hub mounting surface and remove if necessary.

6. Adjust knife clearance to blade as close as possible. The high point of the blade

should just clear the knife as blade is rotated. Be sure blade rotates freely then tighten two 1/2” locknuts to 120 ft. lb. Re-check clearance, by rotating blade one full revolution, after all bolts are tightened.

7. Assemble clamp components loosely to planter front bar as shown in parts view of

appropriate clamp.

8. Position coulter clamps either toward the inside or outside of the planter openers on

each side of the planter to equalize draft. Tighten four 1/2” nuts to secure the clamps.

9. Install coulters on planter by inserting shank up through clamps and tightening 5/8 x 1”

setscrews.

10. Install 5/16 x 2-1/2” cotter pins in all vertical 1-1/2” diameter shanks. This cotter pin

prevents loss of coulter should the clamp setscrews work loose. Cotter pin can be installed between clamp castings or on top, above top casting depending on the shank.

11. Set coulter depth by loosening setscrews in clamp castings. For John Deere 7000

front fold planters there may not be enough up adjustment to operate coulter at proper depth, not more than hub deep. Not all toolbars on John Deere planters operate at the same height. If necessary, cut off top of 1/12” diameter shank to allow proper adjustment.

6

INSTALLATION

12. On John Deere 7000 front fold planters there are two hoses that may interfere with

coulter operation. Loosen hydraulic fittings and swivel hoses up out of the way to provide clearance when coulter flexes up.

13. If you have elected to let coulter swivel, set lock collar to allow swivel in one or both

directions as required. If you have elected to hold coulter rigid, set coulter straight with the direction of travel. Tighten set screw to 110 ft. lb. torque maximum.

14. Set spring tension by adjusting 3/4” lock nut until 1/8” of threads are exposed above

the nut. Tighten 3/4” locknut if greater spring pre-load is required. NOTE: This will reduce vertical movement of coulter.

15. NEVER mount coulters under planter drive shaft to allow coulter blades to contact

shaft when an obstacle is struck. Coulters must be mounted so blade can always flex up and clear drive shaft.

NOTE: Dry fertilizer must be free of chunks greater that 1/4” in size to prevent plugging. Yetter recommends using screened fertilizer or running fertilizer through screen when hoppers are filled. Clean hoppers thoroughly at the beginning of season to prevent plugging problems.

The rubber dry fertilizer tube may appear to be ‘stretched’ when the planter is in the transport position. This does not affect operation of the planter and should not be detrimental to the fertilizer tube.

OPERATION

Yetter Model Generation III fertilizer coulters are designed to apply fertilizer 3” to 5” deep. See your fertilizer dealer for recommended depth and distance away from row for your particular fertilizer. A popular placement setting is 2” below and 2” away from the seed. High deposit rates require the fertilizer to be placed farther away from the row to avoid crop “burn”.

The coulter can be set up to swivel or not swivel as required. By not allowing the coulter to swivel, the distance between seed and fertilizer varies less when planting on contour.

When mounting Model Generation III coulters on 3-point or 2-point hitch planters, the coulters should be set up to swivel, particularly if a 4-wheel drive tractor is used. This reduces the side load on the coulter during operation. It is preferable to allow the coulter to swivel.

IMPORTANT: For proper operation, the planter frame must operate level and at the correct height, usually 20” – 22” while in operation.

In hard no-till conditions the desired operating depth may not be possible. Tighten spring nut to maintain depth if spring is flexing rather than lower coulter to obtain maximum depth.

Planter weight may limit operating depth in hard conditions, particularly with mounted or semi-mounted planters. Be sure planter has enough weight to keep drive wheels on the ground during operation or plant populations can be drastically affected.

7

OPERATION

1. Set coulter blades to run vertical to ground. Operation depth and blade wear can be affected if coulter

is mounted crooked. If coulters are set-up to not swivel be sure they run straight with the direction of travel.

2. After a few hours use, check all bolts and setscrews for tightness.

3. After a few days use, check coulter hubs for loose bearings. There should be no end play in the hub

bearings to allow it to wobble. If necessary, remove hub cap and cotter pin, adjust slotted nut to remove wobble, re-insert cotter pin and replace hub cap.

4. KNIFE ADJUSTMENT IS CRITICAL. Adjust knife-blade clearance regularly, see page 9.

An optional knife scraper, Part #2970-133 or 2976-133 is available to reduce the frequency of adjustment on the fertilizer coulter knife. In addition this allows better operation in tough conditions such as freshly disked soils with abundant trash in the top four inches of loose soil.

NOTE: A ‘bump’ will appear behind knife scraper, on blade where protected, this must be ground off periodically to maintain correct knife-blade clearance.

5. BLADE WEAR can affect operation in loose trash conditions. If knife adjustment does not stop

plugging problems, it may be necessary to replace blade.

6. Dry fertilizer must be free of chunks greater that 1/4” in size to prevent plugging. Yetter

recommends using screened fertilizer or running fertilizer through screen when hoppers are filled. Clean hoppers thoroughly at the beginning of season to prevent plugging problems.

NOTE: The rubber dry fertilizer tube may appear to be ‘stretched’ when the planter is in the transport position. This does not affect operation of the planter and should not be detrimental to the fertilizer tube.

MAINTENANCE

LUBRICATION

DANGER: Always install safety lock-ups or lower the planter to the ground before working on the

machine. Lubricate at frequency indicated with a multi-purpose type grease.

DANGER: Always install all safety lock-ups and safety lock pins before working under the toolbar.

1. Raise the toolbar until is clear off the ground. Remove the gauge wheel and the blade. Remove the

hubcap, cotter pin, slotted nut and washer from the spindle shaft assembly.

2. Pull the coulter spindle shaft assembly from the hub. Remove bearing cones and cups and discard if bearings are being replaced. Clean hub and dry. Remove bearings only and not cups of re-packing.

3. Wash the old grease from the hub, bearing cups, coulter spindle shaft, seal, and bearing cones. Inspect the condition of bearing cups and cones.

4. Apply #2 multi-purpose lithium grease on each bearing. Make sure the space around each roller is filled. Lubricate the bearing cups.

5. Position the bearing in the cup and install the seal. Lubricate the seal lips and proceed with re-assembly of the removed parts including the blade. Blade bolt torque is 90 to 96 ft. lbs.

6. Install outer bearing, washer, and slotted nut. Tighten the slotted nut to 150 in. lbs. while rotating the blade or until a definite drag is felt when the blade is turned by hand. Tighten the nut one slot position to line up the cotter pin hole with a slot. Secure the nut with a new cotter pin.

9

KNIFE ADJUSTMENT

The adjustment of knife clearance to the blade is critical to trouble free operation of the fertilizer coulter, in certain conditions the coulter can “plug” in just a few feet if not correctly adjusted.

1. The disc blade must run concentric. Adjust by loosening four hub nuts and centering the blade.

2. Set knife to rub slightly on blade, especially at bottom of knife. See illustrations above. Tighten lock nuts securely.
