B In The Know

The EvenStream™ Distribution System is a cutting-edge solution for air seeding that optimizes distribution accuracy. It achieves this through a series of clever design elements, including centering vanes, ribbed inserts, and specialized manifold construction. These features work in unison to position the product accurately, minimizing variation and ensuring even delivery at the boot.

Did you know that there are wearable components inside the EvenStream Distribution System? The EvenStream Distribution System relies on the shape and size of polyurethane ribbed sections to maintain product centering and airflow consistency. Over time, wear or buildup on these inserts can compromise their performance, leading to less uniform distribution and diminished overall efficiency.

To ensure the system continues to deliver the precision it’s known for, annual inspections are strongly recommended. During these inspections:

1. Remove the Primary Elbow Top Flange: Gain access to the polyurethane ribbed sections.
2. Visually Inspect for Wear or Buildup: Look for signs of product accumulation or wear on the ribbed inserts.
3. Clean and Replace as Necessary: Clean any buildup thoroughly. If the ribbed inserts have lost their convex shape or the ribs are worn flat, replace them to restore optimal performance

By combining regular inspection of the ribbed sections with proper alignment of the primary elbows, operators can protect their investment, maintain uniform distribution, and ensure the EvenStream™ system continues to perform at its best. Detailed instructions for alignment are provided in the operator’s manual and should be followed closely.

The lifespan of the polyurethane ribbed sections depends on several factors, including:

• Product Type: Abrasive materials (ie. fertilizers) may cause more wear.
• Application Rates: Higher rates can increase stress on the components.
• Acres Covered Annually: The more the equipment is used, the more wear the inserts are likely to experience.

If a machine puts down 250 lb/ac of urea across 4,000 acres in a season, a million pounds of product will pass by these inserts! By understanding these variables and scheduling regular maintenance, operators can extend the life of the EvenStream system and ensure it performs reliably season after season.

Proper maintenance of the EvenStream Distribution System is not just about preserving equipment; it’s about ensuring consistent, high-quality results that directly impact your bottom line. Uniform distribution reduces waste, enhances crop performance, and maximizes return on investment for any farming operation.

With its proven design and commitment to performance, the EvenStream Distribution System is a valuable asset for modern agriculture. By taking the time to inspect and maintain its components annually, operators can continue to enjoy its benefits and keep their air seeding operations running smoothly for years to come.

Managing Hydraulic Demands In Modern Air Seeders

Last year, we explored the intricacies of hydraulic systems for the 7000, 8000, and 9000 I Series Air Carts. Here’s a summary of key points from that article:

• Hydraulic Metering Drives: These air carts use a “series” hydraulic metering system, requiring a consistent 5.5 GPM, regardless of the number of meters operating. Even when meters are electronically turned off, the system continues to demand this flow.
• Fan Selection: Four fan options (Standard, High-Speed, High-Capacity, and High-Pressure) cater to various application rates. Hydraulic flow requirements range from 12 GPM for a Standard fan to 32 GPM for a High-Pressure fan. Selecting the appropriate fan for your application needs ensures efficiency and avoids excess hydraulic demand.
• Drill Hydraulic Requirements: The depth circuit for openers and MRBs ® (Mid Row Banders ® ) typically requires 30 GPM. While this flow is primarily needed during headland maneuvers, it “borrows” from the flow allocated to fans, creating a critical need for adequate hydraulic capacity during transitions.
• Total System Requirements: Combining the flow for fans, metering circuits, and drills, the total hydraulic demand for a typical seeding system can exceed 88 GPM. Meeting this demand ensures operational efficiency and prevents underperformance in critical situations.
• Tractor Engine RPM and Hydraulic Flow: Modern tractors often require a minimum RPM to deliver adequate hydraulic flow and pressure. During hydraulic demand spikes, such as lowering openers or re-engaging fans at the headlands, maintaining engine RPM is necessary to maintain system performance.

ECO Modes: Incompatibility With Air Seeder Demands

While tractor ECO modes are designed to optimize fuel efficiency, they are not well-suited for the hydraulic demands of air seeders. These modes prioritize engine power efficiency, often by lowering RPM, which inadvertently sacrifices hydraulic capacity when it is needed most.

A prime example of this issue arises on headlands. When the tractor’s ECO mode senses reduced engine power needs, such as during turns, it throttles down and gears up. However, this is precisely when hydraulic demand spikes. Hydraulic flow is required to lift openers, actuate Auto Sectional Control (ASC) valves, and maintain fan speed as the distribution system prepares for re-entry into the ground. Insufficient hydraulic flow during these moments can lead to operational inefficiencies, poor product placement, and potential gaps.
