Great Plains Manufacturing, Inc. Table of Contents Index Adjustments 39 Contact Drive Tension Refer to Figure 35 and Figure 36 Occasionally, due to planting height or planting conditions, it may be necessary to adjust the spring tension to keep the contact drive tire from slipping. For example, if you experience low seeding rates in wet conditions, it may be possible to compensate for this by increasing contact drive tension, by tightening 4 bolts 1 (2 on each contact drive).
40 PD8070 Table of Contents Index Great Plains Manufacturing, Inc. Marker Adjustments There are four adjustments for markers: • Marker Width Once set for a specific row spacing, this only needs periodic checking to ensure the clamp is secure. • Disk Angle Even if your row spacing rarely changes, you may need to adjust disk angle for soil conditions and planting speed. • Marker Fold/Unfold Speed Once initially set by your dealer, this rarely needs modification.

Seed Hopper: standard (not shown - sits above meter) 1. Parallel arms: standard Each row unit is mounted on the planter with spring-loaded parallel arms which allow each row unit to independently move up and down while staying horizontal.
46 PD8070 Table of Contents Index Great Plains Manufacturing, Inc. Row Unit Down Pressure Row unit springs provide the primary down pressure necessary for row unit disks to open a seed trench. The springs allow the row units to float down into depressions and up over obstructions. Springs also provide down force on coulters when using optional row mounted coulters, and provide the primary down force on seed firmers (optional) and press wheels.

Table of Contents Index Adjustments 47 Row Cleaner Adjustments 1 Refer to Figure 48 Optional rigid tine cleaners are unit-mounted, using UMC-RC: Unit-Mount Coulter RC (on coulter bracket, with or without a coulter disk present). 2 Sharp Object Hazard: Row cleaner tines, casting edges and coulter blades are sharp. Wear hand protection when working in this area. There are two adjustments: 1.
48 PD8070 Table of Contents Index Great Plains Manufacturing, Inc. Coulter Adjustments The ideal operating depth for coulters is 6.4 mm (1⁄4 inches) 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.
Table of Contents Great Plains Manufacturing, Inc. Index Adjustments 49 Row-Unit Opener Adjustments 30 Series openers have three adjustments: 1. planting/seed depth 2. gauge wheel/opener disk clearance 3. opener disk angle 1 Setting Planting Depth Refer to Figure 51 The “T” handle 1 sets planting depth by limiting the how high the side depth gauge wheels ride relative to the opener disks. The position of the seed tube itself is fixed relative to the disks, and is not adjusted.
50 PD8070 Table of Contents Index Great Plains Manufacturing, Inc. Adjusting Disk Angle & Side Gauge Wheels Refer to Figure 53 For 51 mm (2 inch) planting depth, adjust side gauge wheel angle so wheels contact row unit disks at the bottom of wheel - in clock hand notation, between 4:00 and 8:00 o’clock. Check with row units in soil so wheels are held up. At the same time, keep side gauge wheels close to opener disks so openers do not plug with soil or trash.

Seed Meter Setup and Adjustment Your PD8070 Planter was originally supplied with a choice of brush meter, or 12-finger pickup meter. • The brush meter accepts a selection of seed plates. Seed plate exchange is described on page 19. 1 4 4 3 • The finger pick up meter has an adjustable brush, and alternate inserts are available for the backing plate. 2 To change meters, see “Meter Maintenance” on page 72.
Great Plains Manufacturing, Inc. Table of Contents Index Finger Meter Brush Adjustment The brush reduces or eliminates “doubles” (delivering two seeds per finger), but if set too aggressively can cause “skips” (delivering no seed on some fingers). As needed, adjust for minimal doubles and skips.

54 PD8070 Table of Contents Index Great Plains Manufacturing, Inc. Finger Meter Inserts Refer to Figure 59 The backing plate is equipped with an “A” insert 1 . In tests, this insert provides the best performance in most seed sizes. However, there are two alternative inserts that can be used. Before changing to a different insert, please consult with a Great Plains service representative for a recommendation. 1 The insert type is molded into the back. Changing inserts requires meter disassembly.
