Parallel Link

• Consists of an upper and lower arm that extends rearward and attaches to the sturdy cast row unit frame
• The cast lower link carries the weight of the 165 pound row unit.
• The upper link allows the row unit to lift and lower level, ensuring even seed depth placement in any soil condition
• Provides the potential for faster ground speed and more acres seeded per day
• Allows 8.5 in of upward travel and 11.5 in of downward travel for maximum ground following capability
• The parallel link features oil impregnated copper iron alloy bushings which don't require grease reducing maintenance and increasing uptime

Down Pressure Spring

• Exclusive to Case IH is a unique variable down pressure spring on each row unit.
• Provides pressure on an individual row unit to assist the row unit engagement in the ground
• Ensures even emergence and minimized compaction across terraces and uneven terrain

Secure Depth Adjustment

• A single, spring loaded T-handle allows simple adjustment of row unit depth at each opener, no tools are required for adjustment
• As the T-handle is adjusted fore and aft, the gauge wheel rotates up or down to adjust seeding depth for an individual row unit
• The row unit and the T-handle are made of cast iron
• True 0-3.5 in depths are available in 14 different increments
• Every other notch is identified on the case frame to help the operator apply the same depth across the tool and easily return to that preferred depth
• The only greaseable point on the row unit is found on the gauge wheel adjustment spindle, requires greasing every 50 hrs. or once per season
• The tolerance between the handle tab and the notched row unit frame is tight to help retain the handle in place and provide worry free depth control

Rank Down Pressure

• Each of the ranks across the drill utilizes a cylinder to lift and lower the rank, down pressure is sustained by this cylinder.
• The number of row units on each rank are matched to cylinder size to minimize the differential pressure between ranks
• The down pressure is maintained across the full width
• Down Pressure can be adjusted manually via a mechanical knob and easily visible gauge on the down pressure manifold  or via in-cab adjustment on the AFS Pro 700 or ISOBUS
• Available down pressure range is between 200-1300 psi (30 ft.) or 200-1450 psi (40 ft.)

Pressure Adjustments

• There are three different down pressure settings to meet the field conditions: 59 lbs, 71 lbs and 84 lbs
• Adjustment of the pressure is easily done by moving the single handle to a different notch

Single Disk Opener Coulter

• Made from boron earth metal steel and measures 18 inches in diameter and is 0.197  (when the coulter's outer diameter reaches 16 in, it should be replaced)
• The coulter is positioned at a 7 degree angle to open a high quality seed trench
• The opener hub utilizes a heavy-duty, double row, triple lip sealed bearing; no bearing maintenance is required
• The single bevel opener is ideal for cutting residue because the angle of entrance is close to 45 degrees, even at shallow depths
• Allows the opener to slice and cut through residue to reduce hair pinning that can reduce soil-to-seed contact germination and ultimately overall yield

Opener Scraper

• Critical to keeping the opener disk clean is the scraper with tungsten carbide wear components
• Extends further down the opener to protect the seed as it is dropped into the seed trench
• Provides proper seed placement for high yield potential
• The spring loaded scraper fits behind the profile of the angled opener which prevents it from dragging in the soil and seed trench
• Provides lower overall draft of the entire disk drill and lower down pressure requirements

Seed Tube

• Helps guide the seed towards the seed trench after metering
• Features a unique tube with a forward facing design
• Directs the seed toward the scraper which stops the seed and allows the seed to fall vertically in the seed trench and reduces seed tumble once it reaches the trench
• Competitors sometimes utilize a seed-loc wheel to keep seed within the seed trench; however, in certain soil conditions their seed-loc wheel can actually pull seed out of the trench
• The Precision Disk Drill row unit doesn't require a seed-loc wheel due to the design of the scraper, seed tube and closing wheel
• A deflector is located behind the scraper and seed tube to help contain any seed that might attempt to bounce out of the seed trench

Closing Wheels

• The four-inch wide, double-edged closing wheel is designed specifically for closing in any condition
• Sand, loam or clay, even in soft ground, the closing wheel is able to float and close the seed trench
• This extremely durable wheel is tilted slightly to one direction
• The raised edge of the wheel breaks the sidewall, the opposing edge captures the soil, preventing it from moving outside of the trench area

Rockshaft

• The Rockshaft is responsible for carrying and providing the down pressure for the two unit ranks
• The majority of the sub-frame and rockshaft is welded together for additional strength
• Makes the frame more robust and provides superior durability over bolted joints

Gauge Wheels

• Supporting the weight of the row unit is the 4.5 in wide gauge wheel
• Provides consistent seed depth and seed trench in all operating conditions, including no-till and clay soils

Additional Weights

• Additional weights can be added to the tool bar if needed for hard ground conditions and deep seeding depths
• Weights could be needed in soil conditions that are no-till and/or clay based soils
• Tilled ground typically doesn't require any additional weights
• Optional weight brackets are available for easily adding additional weights to both wings and center section
• No more than 1400 lbs should be added to the center section
• No more than 600 lbs on each wing.
• 100 lb (45 kg) suitcase weights are available from the CNH parts organization (part #86988727)

Main Frame

• The main carrying frame utilizes 6" x 10" x 3.8" (15 cm x 25 cm x 9.5 cm) wall tubes to support the row unit carrying subframe
• The center main frame tubes are oriented in a "V" to distribute the weight of the main frame, adding additional support and stability during transport
• The front caster wheels travel in a different path than the rear caster wheels, providing exceptional weight distribution, reduced ground pressure for even emergence and allowing for a smaller transport envelope

Transport

• The vertical fold design allows for lowest transport height in the industry as well as narrow transport widths
• The 25 ft and 30 ft Precision Disk Drills also utilize a wing lock for safe transport
• To fold or unfold the tool, a single remote lever in the tractor is used
• While transporting or pulling in/out of a field, the ground clearance of the openers is 8.5 in
• The wide profile of the transport wheels provide the stability to move the disk drill confidently, even at higher roading speeds
• Maximum transport speed should not exceed 20 mph

Wing Frames

• A three section frame drill with single fold wings provides narrow transport
• Each wing pivot utilizes hardened grade 8 wing pins with replaceable hardened bushings for long wear life
• A single fold cylinder is used to fold the wings, providing fewer service points and resulting in more uptime and reliability
• When in field position, the wings can flex 15 degrees up and 10 degrees down for superior ground following

Paint

• Nearly every part of the Precision Disk drill is powder coated to provide a superior paint coating
• Prevents corrosion
• Resistant to impacts and paint fading UV rays

Adjustments and Maintenance

• The operator can easily adjust the rear rank depth and closing system pressure
• No need to crawl on top of the drill to make any adjustments
• The depth adjusting T-handle on each row unit is easy to reach and adjust

Assembly

A majority of the set-up is completed before it leaves the factory

• Reduces set-up time
• Improves reliability
• Increases up-time

• Air pack system with associated hydraulics/electronics (25, 30 and 40 ft)
