Description 

The W240 Weed Wiper is designed for the selective application of herbicide to weeds / vegetation on 
pasture. 
 

The W240 Weed Wiper is a trailed attachment, with applicator roller rotated around a horizontal plane in 
direction counter to the direction of motion. This ensures even coverage of the waterborne herbicide to 
the underside of the weeds. The herbicide itself is applied to the applicator roller via sprayer nozzles 
located above, fed from a tank and pump fitted to the top of the machine. 

 

These machines should however only be used to perform tasks for which they were designed - use of the 
machine for any other function may be both dangerous to persons, and potentially damaging to 
components. Use of the machine beyond the stated usage may invalidate any applicable warranty, as well 
as being potential in breach of applicable safety regulations. 

 

Weed wiping using herbicide is a controlled practice, and as such should only be undertaken by 
operators with the correct licences / tickets for the territory the machine is being used in!
