Wiping out those weeds

Over the years, Ashburton-based Rotowiper has pursued one main objective – to design and manufacture an effective, cost-efficient method of controlling/eradicating weeds in pasture and crops.

Receiving positive feedback from farmers and growers around the world, the company has achieved its key goal. Recently, it has been developing new formats to meet individual conditions in different markets around the globe.

The new Rotowiper “TR” series is a case in point. It is already proving to be successful, featuring ease of operation with simple height adjustment, delivered by a new single, heavy-duty ratchet assembly. Likewise, the roller drive engagement is actioned with a simple spring-loaded pin, meaning the machine can be quickly disengaged for transport or re-engaged once back in the paddock

Other features include a drawbar that can be raised vertically for transporting or storage, without tools. It features stainless steel covers throughout to give the machine a quality appearance, but more importantly delivering durability and improving its longevity.

A redesign of the frame features larger, box section steel, a “box” style frame layout.

Both give the machine superior strength and durability. Its heavy-duty stub axles are equipped with high-speed bearings to help endure the rigours of high-speed road travel – alongside the punishment delivered on unmade farm tracks and large acreages.

For those using an ATV or UTV style towing vehicles, the chemical tank has now been repositioned from the drawbar to above the application roller. This moves weight transfer from the rear of the vehicle, while also allowing a levelling device to be fitted if required.

Rotowiper is able to offer a bespoke production and configuration service.

The company recently completed its largest machine, to date, with a 24-metre working width and one metre clearance under the application roller. Comprising seven individual roller sections, the machine was developed for a Canterbury contractor who was dealing with bolters in the increasingly popular fodder beet crops being grown.

The machine’s layout allows excellent ground contouring over the full working width. It uses a combination of hydraulic and electronic controls that enable it to quickly move on from its original intended use and also deal with other weeds, such as Californian thistles.
