Precision Disk 500 

PARALLEL LINK

DOWN PRESSURE SPRING

• 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
  • Ensures 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 bushings feature oil impregnated copper iron alloy bushings
  • Don’t require grease, reducing maintenance and increasing uptime

• 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.

ROCKSHAFT

• 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
  

RANK DOWN PRESSURE

ADDITIONAL WEIGHTS

• Each of the ranks across the drill utilizes a cylinder to lift and lower the rank
  • Rank down pressure is also 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 across the full width can be adjusted via
  • Mechanical knob adjustment on the down pressure manifold
    • Features a mechanical gauge positioned on the toolbar to allow the operator to easily view the current down pressure
  • In-cab adjustment on the AFS Pro 700 (or ISOBUS)
    • Features an electronic display
• Available down pressure range is between
  • 200-1300 psi (30 ft.)
  • 200-1450 psi (40 ft.)

• Additional weights can be added to the tool bar if needed for hard ground conditions and deep seeding depths
  • 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)
  

SINGLE DISK OPENER COULTER

OPENER SCRAPER

SEED TUBE

• Made from boron earth metal steel and measures 18 inches in diameter and is 0.197 in.
  • 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
    

• 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

• Help 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
• To overcome the seed tumbling or prevent the seed from exiting the seed trench prior to closing, often a seed-loc wheel is used on competitive openers
  • In some soil conditions the 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

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

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

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
  • One raised edge of the wheel breaks the side wall
  • The opposing edge captures the soil, preventing it from moving outside of the trench area

PRESSURE ADJUSTMENTS

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

MAIN FRAME

WING FRAMES

TRANSPORT

• 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 sub-frame
• The center main frame tubes are oriented in a “V” to distribute the weight of the main frame
• Adds additional support and stability during transport
• The front castor wheels travel in a different path than the rear castor wheels
• Provides exceptional weight distribution especially in softer soils and reduced ground pressure
• Reduced ground pressure for even emergence
• Allows for a smaller transport envelope
  

• Is a three section frame drill with single fold wings to provide 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
• Provides fewer service points and results in more uptime and reliability
• When in field position, the wings can flex up 15 degrees and 10 degrees down for superior ground following
  

• The vertical fold design allows for lowest transport height in the industry as well as narrow transport widths
• The 30 ft. Precision Disk Drill also utilizes 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.
