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
  • 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

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.

ADDITIONAL WEIGHTS

• 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)

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

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

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

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

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

TRANSPORT

• 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.

HIGH FLOTATION

• Stubble resistant tires at all locations
• 16 total wheels
• Front of mainframe
  • 12.5Lx15 dual on castoring walking tandem axles
• Front and rear of each wing
  • 12.5Lx15 duals on walking beam axles (front on castor)
• Rear of mainframe
  • 18Lx16.1 dual wheels on walking beam axles

AIR PACKAGES

• Standard air package
  • Ideal for almost every crop and fertilizer type
  • The primary and secondary runs feature UV resistant flexible PVC with a steel header and EZ-Flow manifold
• Extended Wear
  • Ideal for highly abrasive crops like rice
  • The primary run features 2.5 in. ID flexible PVC hoses, each with a Urethane Liner that resists wear and extends the life of the hose
  • The secondary run is UV resistant 1 in. flexible PVC hose

SPLIT RANK SEEDING

• Offers the ability to easily split the front and rear ranks to allow seeding with only the front or only the rear rank
  • 15 in. row spacing
• Raising the ranks, then rotating either the upper (front rank) or lower (rear rank) pair of valves will prevent the rank from lowering
  • Rank lock-up pins should also be inserted
• Along with locking up the front or rear rank, stopping the seed is also required for split rank operation
  • A header insert kit should be ordered to stop seed flow to the split rank

MANIFOLD

• EZ Flow Header is designed for easy serviceability and accurate product distribution
• A replacement steel tip on the insert reduces abrasion effect and prolongs life
• Quick access to inspect riser tube and manifold ports

FLOW MONITORING OPTICAL SENSORS

• Optical sensors that monitor the product flow through the delivery system are optional
• Advantages include:
  • Quickly alerts product flow concerns for quick resolution
  • Reduces skips
  • Ensures higher yields
• When an obstruction is detected, the operator will hear an audible alarm in the cab and the blocked run will be displayed on the console
• These sensors provide non-contact monitoring as either primary or secondary run systems for single-shoot configurations

HEADER STAND PRIMARY DISTRIBUTION

• Standard Wear air package
  • The patented dimpling in the header stand allows for randomized air flow and creates even seed distribution to the EZ Flow header
  • The dimpling pattern eliminates overloading of seed to one side of the header stand
• Extended Wear air package
  • Includes a high wear header that prevents areas with high amounts of seed contact from wearing out
  • The header includes a reinforced area at the elbow as well as reinforced dimples to prevent the header from wearing out prematurely
