Features
Setting a Higher Standard in Productivity and Agronomics For Seeding
Case IH engineering worked tirelessly through the Customer Driven Product Definition (CDPD) process to bring an all new row unit to the marketplace. The new row unit cuts residue, opens a high quality, uniform seed trench, delivers the seed perfectly, and closes the trench better than any row unit in the market place. And even with all these features, it requires less maintenance and utilizes less power to pull than prior designs and competitive units. This makes the producer more efficient, improves yield potential and makes them more productive.
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
