Introduction Great Plains Manufacturing, Inc. 3 Introduction Description of Unit U These kits add small seeds planting capability to many Great Plains 7-foot and 10-foot end-wheel drills. R These kits also replace an older kit (before July 1991), and may be used to upgrade drills with the previous small seeds components. The kit drive is independent of main seed rate, and unaffected by changes to main seed box Drive Type.

Installation Instructions Great Plains Manufacturing, Inc. 5 Installation Instructions Before You Start Most accidents are the result of negligence and carelessness, usually caused by failure of the operator to follow simple but necessary safety precautions. Allow no one to install the small seeds attachment before carefully reading this manual. Due to evolving manufacturing practices, some subassemblies may already be completely pre-assembled.
6 7ft and 10ft EWNT Small Seeds Great Plains Manufacturing, Inc. Update Clutch Shaft The existing clutch shaft is updated with a third sprocket for Small Seeds. The clutch shaft is located at the front of the main seed box, below the gearbox or transmission. If you have a late model drill, you may already have a Small Seeds drive sprocket installed. Refer to Figure 4 8. Inspect the existing clutch shaft 1 .
Installation Instructions Great Plains Manufacturing, Inc. 7 Seed Box Mounting Refer to Figure 5 If you have a late model drill, you may already have a Small Seeds-ready main seed box, with mounting holes present, and occupied by fasteners. 16. Inspect the back of the main seed box. If there are fasteners at the hole positions in Figure 5, remove them (they are not re-used), and continue at “Mount Small Seeds Box” on page 8. Mark Holes for Drilling Box 17.

Installation Instructions Great Plains Manufacturing, Inc. Press Wheel Hose Delivery Hardware Start with the row unit on the right end of the drill. 207 206 15 214 71. Before mounting the first retainer, examine the row unit. Decide whether Small Seeds delivery is to be in-row or between rows. If Seed-Lok is present, that constrains where the retainer can be placed. Refer to Figure 17 72.

Orient the angles 181 so that the ends with the holes furthest apart are to the front.
Operations Great Plains Manufacturing, Inc. 17 Operations Loading Seed Small Seed may be loaded in the field or prior to transport. The drill must be hitched for seed loading. The mainframe may be raised or lowered. Lowered places the walkboards closer to the ground, reducing effort when manually loading bagged seed. Small Seeds Box Loading 1. If loading prior to transport, and calibration has not yet been done, set Seed Rate Handles to 0.
18 7ft and 10ft EWNT Small Seeds Great Plains Manufacturing, Inc. Small Seeds Rate Calibration Differences will exist between the tested seed and field conditions used to generate the Small Seeds Rate Charts, and your seed and conditions. To accurately achieve your target population, Great Plains recommends calibrating. Perform the calibration with the drill lowered to planting position (if the openers are raised, the clutch disengages). Leave the tractor hitched for movement control.
Operations Great Plains Manufacturing, Inc. 10. Divide the net seed weight by three. Multiply by number of openers on your drill to determine the total of pounds-per-acre seeded. 19 NetWeight MeasuredRate = ------------------------ × RowCount 3 For example: a 7.5in drill has 15 rows: 10.5 lbs/ac 2.1 10.5 = ------ × 15 3 11. The Seed Rate Handle scale is a percentage of meter opening, and is quite linear near scale center. Calculate a new scale setting based on the test.
20 7ft and 10ft EWNT Small Seeds Great Plains Manufacturing, Inc. Small Seeds Row Shut-Off Refer to Figure 20 If alternate row spacing is required for small seeds, optional plugs are available to block flow inside the seed box tray. 1. Cleanout seed. The seed box must be empty prior to inserting plugs. See “Small Seeds Box Cleanout” on page 23. 2. Before installing plugs, inspect the seed boxes for existing factory-installed plugs. These are blocking extra unused seed ports.

Maintenance Great Plains Manufacturing, Inc. 23 Maintenance Small Seeds Box Cleanout 1. Open lid of each box and scoop out as much seed as possible. 2. To recover remaining seed, place a collection tarp under the small seeds tubes at the openers. 3. Raise drill. 4. Set seed rate handles to 100. 5. Rotate gauge wheels until no seed flows. 6. If a vacuum cleaner is available, remove any residual seed from top of meters. Chain Maintenance Inspect and lubricate chains regularly.
