Wiping out weeds made easier

From 1.8m to 12m, in several configurations, the company has the ability to custom build to individual configurations – such as a 500mm wide unit for use under grape vines. Machine formats include linkage mounted (LMU), fold-up (FU) and trailed (TR) versions.

Working with a spray line mounted above a reverse-rotating, carpeted roller, the sprayer moistens the roller with herbicide and this in turn ‘wipes’ against the targeted weeds.

The company claims this targeted approach offers substantial cost savings over the traditional approach of blanket spraying and the ongoing use of the existing crop.  

Rotowiper’s TR series, which has replaced the well-known WCF series, consists of five key models designated as TR18 (1.8m), TR24 (2.4m), TR28 (2.8m), TR32 (3.2m) and TR45 (4.5m).

Developed with users in mind, the TR has a single ratchet, height adjuster and a spring-loaded roller to drive the engagement system, which all helps to speed up the transition from transport to work. A correct working height allows maximum contact with the weeds, without damage to the crop underneath. Tank levelling keeps the chemical reservoir level when working at different heights or when connected to different towing vehicles.

In the same vein, storage and ease of transport is addressed with fold-up drawbars on the complete range. General construction uses a double frame to handle tough high-country conditions. Strong, RHS single wheel legs, and solid stub axles, fitted with high-speed wheel bearings are part of the standard build. Purchasers can also choose an option of a high-quality paint or zinc finish to the frame, with the latter preventing corrosion and extending the working life of the unit.

For those looking to cover larger areas, the 12m heavy-duty trailed model is a good fit. Made up of a single 2m central unit and four 2.5m outer sections that are driven hydraulically. The unit also features hydraulically-adjustable depth control legs.

A heavy-duty frame carries a 400 litre spray tank, which is said to offer the ability to cover 20 to 40 hectares per fill. This model has a transport width of just 3.1 metres.
