Having been on the market for over 10 years, the King Cobra K2 travelling raingun continues to be a popular choice for farmers, says owner Numedic.

The company says the raingun is popular among farmers wanting high-volume irrigation at low application rates, packed into a sophisticated, well-engineered unit that is easy to set up and operate.

The patented, New Zealand-designed and manufactured product has proven itself on farms of varying sizes, delivering efficient effluent distribution, supporting compliance and freeing up valuable labour hours.

High volume, low application rates

The K2 is designed to distribute large volumes of effluent while maintaining low application depths. Application depths can be as low as 1.3mm, helping farmers manage application rates to suit soil conditions and reduce the risk of ponding and runoff when operated correctly.

With application rates from approximately 4.2mm per hour, the system offers flexibility for farms where soil type, slope and environmental considerations influence effluent irrigation practices.

The raingun delivers jet lengths of up to 48 metres, allowing irrigation widths up to 100 metres under suitable operating conditions. This wide coverage helps reduce the number of runs required to irrigate an area, improving efficiency and reducing the time operators spend moving equipment.

Control and flexibility

A key feature of the K2 is its six-speed gearbox, which allows travel speed to be adjusted to suit the required application depth and operating conditions. This gives farmers greater control over how effluent is distributed.

The raingun can be configured for full-circle, partial-circle or one-sided application, offering flexibility when irrigating paddocks with different shapes and boundaries. Directional application can also be useful where irrigation needs to be managed around drains, waterways, roads or other sensitive areas.

Depending on pump capacity, available pressure and nozzle selection, the K2 can handle large effluent flows, making it suitable for operations requiring high-volume distribution.

Sophisticated design, simple operation

Despite its sophisticated engineering, the K2 King Cobra is designed to be straightforward to set up and use. It can also be operated as a stationary irrigator when required.

Automation is another important benefit. Once correctly set up, the raingun can operate with limited operator intervention, allowing farmers and staff to focus on other farm tasks rather than continually managing irrigation equipment.

Built around practical farm requirements

More than a decade in the market has given the K2 King Cobra an established place in effluent irrigation. Its combination of high-volume delivery, adjustable travel speeds, wide irrigation coverage and straightforward operation addresses the practical requirements of modern dairy farming.

With accessible technical information, parts support and dealer assistance, Numedic continues to focus on making the ownership experience as straightforward as the machine itself.

For farmers looking to improve effluent irrigation efficiency while making better use of available labour, Numedic says the K2 King Cobra offers a proven, purpose-designed solution: sophisticated irrigation engineering, without unnecessary complexity.
