The Nelson 3000 Series Pivot Products are a range of irrigation sprinklers designed for high performance and efficiency in agricultural applications. This series includes various models such as the R3000 Rotator, S3000 Spinner, A3000 Accelerator, D3000 Sprayhead, N3000 Nutator, and T3000 Trashbuster, each with specific features tailored for different irrigation needs.

Function Description

The primary function of the 3000 Series Pivot Products is to deliver water uniformly and efficiently to crops. They are designed to be part of a pivot irrigation system, ensuring optimal water distribution across the field. The advanced design incorporates speed control and built-in uniformity to maximize irrigation effectiveness.

Different models within the series offer specialized droplet control solutions:

Gentle: For sensitive crops and soils, providing a soft application of water.
Windfighting: Designed for maximum irrigation efficiency even in windy conditions, minimizing drift and ensuring water reaches the target area.

The modular design allows for easy assembly, maintenance, and customization with various components like nozzles, plates, and caps.

Important Technical Specifications

The 3000 Series products are designed with specific components that contribute to their performance:

Nozzle and Body Assembly: The nozzle (e.g., 3TN Nozzle, 3000FC Nozzle) is sandwiched between the adapter (e.g., Square Thread (ST) Adapter, 3/4" Adapter #9410) and the body (e.g., R3000 Rotator/S3000 Spinner Body #9412, A3000 Accelerator/D3000 Sprayhead Body #9428). The adapter must be securely hand-tightened into the body for proper function.
Plates: These are crucial for defining the spray pattern and droplet size. The plates are specifically engineered for high performance. Examples include Rotator Plates (D6 12° Orange, D6 12° Brown), Spinner Plates (D6 12° Red, D6 21° Yellow), Accelerator Plate, Spray Plates (Orange, Turquoise, Purple, Yellow, Green), Nutator Plates, and Trashbuster Spray Plates. The plate is pressed firmly onto the shaft, ensuring it passes two stops (or clicks) for correct seating.
Caps: The cap assembly (Cap + Plate) secures the plate to the body. Examples include Rotator Cap (Blue) #9539, Spinner Cap (Gray) #9540, Accelerator Cap (Maroon) #10402, Flip-over Spray Cap (Black) #9429, Nutator Cap Assembly (Green) #10319-001, and Trashbuster Cap Assembly (Purple) #9539.
Pressure Regulators: Universal 3000 Pressure Regulators (e.g., 6 PSI #9672-001, 10 PSI #9672-002, up to 50 PSI #9491-008) ensure consistent pressure for optimal performance.
Modular Pivot Weight: A 1 lb. Modular Pivot Weight #10130 can be fitted on the regulator or directly on the body, particularly for the N3000 Nutator.
Hose Barb Fittings: Various hose barb fittings are available, including Square Thread #9601, MNPT #10148, and FNPT #10057.
LEPA Options: The system supports Low Energy Precision Application (LEPA) with components like the HD3000 Hose Drag Adapter #45427 and Bubbler Attachment #10677.
Dual Nozzle Clip: The Dual Nozzle Clip #9742 can be used with all 3000 Series Sprinklers and plates, except the D3000 with the Red Plate.
Plate Dimensions: The plate typically extends approximately .14" (3.6mm) on R/S3000 models and .07" (1.8mm) on A3000 models.

Usage Features

The 3000 Series Pivot Products are designed for ease of use and adaptability in various irrigation scenarios:

Assembly:
- Nozzle/Body Assembly: The nozzle is placed between the adapter and the body. The adapter is then securely hand-tightened into the body.
- Plate Assembly: For R3000 & S3000 Sprinklers, align the flats on the shaft with the flats on the bottom of the plate, then press the plate firmly onto the shaft until two clicks are heard. For A3000 Sprinklers, press the plate firmly onto the shaft until one click is heard.
- Cap Assembly: The cap assembly (Cap + Plate) is screwed onto the body clockwise until a "click" is heard.
Disassembly:
- Cap Disassembly: To remove the cap, push the cap assembly (Cap + Plate) into the body to compress the springs, then turn the cap counter-clockwise.
Customization: The wide range of interchangeable plates, nozzles, and caps allows users to customize the sprinkler's performance to suit specific crop types, soil conditions, and environmental factors.
"In the Crop Canopy" Application: For applications where the product operates within the crop canopy, it is recommended to check the tightness of the Body and Adapter connection once a year.

Maintenance Features

The design of the 3000 Series Pivot Products facilitates straightforward maintenance to ensure longevity and reliable performance:

Secure Hand-Tightening: The instruction emphasizes securely hand-tightening the adapter into the body, which is crucial for preventing leaks and maintaining proper function.
Annual Connection Check: For "in the crop canopy" applications, an annual check of the tightness of the Body and Adapter connection is recommended to prevent issues that might arise from constant exposure and operation.
Protective Shield: The plates include a protective shield that provides longer wear life and enhanced reliability, reducing the frequency of component replacement.
Easy Disassembly: The cap's push-and-turn mechanism for removal simplifies access to internal components for cleaning or replacement.

Nelson Irrigation Corporation warrants its products for one year from the date of original sale against defective materials and workmanship under normal use and service, provided they are used within the specified working specifications. The manufacturer's liability is limited to replacement or repair of defective parts.
