CAUTION: Always close opener lock-up valve before servicing machine. If a hydraulic failure should occur while you are under the machine, the openers would fall rapidly and cause severe injury or death to you or others.

Press Wheel (A)

Press wheel down force is adjustable by placing spring (B) using one-of-three settings (C, D, and E) based on soil conditions and seed depth. Maintain uniform down force on all press wheels for best seed-to-soil contact, which promotes germination and optimum emergence.

• MAXIMUM DOWN FORCE (C) is used for deep seeding depth.
• MEDIUM DOWN FORCE (D) is used for moderate seeding depth.
• MINIMUM DOWN FORCE (E) is used for shallow seeding depth or to reduce mud build-up from wheels when operating in wet conditions.

Spring pressure should be removed only if mud builds up on press wheels.

Closing Wheel (F)

Adjust closing wheel down-pressure to close furrow and leave loose soil over the seed.

Use no more closing wheel down-pressure than required to close furrow.

Slow and/or erratic emergence can result if:

• Excessive closing wheel down-pressure causes seed zone compaction.
• A solid “ribbon” of soil is placed over the seed. This is generally caused by operating in wet soil conditions.
• Furrow is not closed.

Place closing wheel spring (G) in one-of-four setting positions (H, I, J, K), which best suits your soil type, and closes furrow without compacting soil.

• HEAVIEST FORCE (H)—Heaviest soil conditions.
• HEAVY DOWN FORCE (I)—Heavy wet soil.
• MEDIUM DOWN FORCE (J)—Most common soil types.
• LIGHT DOWN FORCE (K)—Light, loose or sandy soil.
