This attachment is a complete right hand spin weeder disc assembly. It mounts to a spin weeder frame (purchased separately).
The 18" diamter spin weeder disc is lined with long wearing 1/4" thick UHMW plastic. The disc operates below soil level and is ground driven, rotating around the vineyard stock to minimize damage. The spring loaded mechanism is adjustable for spring tension so that the disc can be fine tuned to the crop and soil conditions.
