Measure off the sample distance, balanced in between where seeding started and stopped. 8. Count the number of seeds over the distance measured. Also note the consistency of the seed spacing. 9. Compute the rate for a full acre or hectare. For a 1/1000th sample, multiply the counted seeds by 1000. For a 1/200th sample, multiply the counted seeds by 200.

66 1625AHD/AHL Table of Contents Great Plains Manufacturing, Inc. Sprocket Indexing (Stagger) 28420 If you are planting: • with a seed disc having 24 cells or less, • twin-row crops, • at seed populations below 161 000 seeds/ha (60,000 seeds/acre) you can synchronize each pair of adjacent meters in a twin row for maximum seed-to-seed spacing between the units of the pair. If the initial indexing does not provide equal spacing, see “Indexing Fine Adjustment” on page 69.
Great Plains Manufacturing, Inc. Table of Contents Sprocket Indexing (Stagger) 67 Indexing Preparation Tools required: • 23 mm (7⁄8 inch) open end wrench • 9.5 mm (3⁄8 inch) socket wrench, or any socket wrench with 3⁄8 in square drive • 812-391C timing tool (located at left lights) 1. Find (in page 73-page 75) the sprocket indexing chart for your row spacing, cell count and desired seed population. Note the “Initial Rear Tooth Number” value in the second column. 2. Raise the planter.
68 1625AHD/AHL Table of Contents Great Plains Manufacturing, Inc. Refer to Figure 14 6. At the rear (long mount) row unit of each pair, note which sprocket tooth is at the index mark 2 . If the sprocket is already at the chart value, skip to step 12. Otherwise, complete step 7 through step 10 for that row. 2 Refer to Figure 15 7. Place the timing tool 3 over the meter shaft. Attach a 9.5 mm (3⁄8 inch) socket wrench to aid in rotation.
Great Plains Manufacturing, Inc. Table of Contents Sprocket Indexing (Stagger) 69 Indexing Fine Adjustment If, after indexing, the twin-row side-to-side seed stagger is substantially imbalanced, it is possible to make small adjustments that may correct it. Imbalance can occur over time as row unit chains wear and stretch. The Indexing charts on pages 73 and 75 provide columns for alternate rear row sprocket alignments. These settings move the placement of the rear seed drop.

Refer to Figure 17 The dry fertilizer system is powered by a dedicated ground drive wheel 1 , which has a lock-up capability, but no rate adjustments in the ground drive assembly. Coarse fertilizer rate is set by Range gears right side of the meter. Fine rate is set by a crank adjuster gearbox.
