In ODOT Division Two, we have purchased three (3) GrassWorks Weed Wiper, one (1) pull type and two (2) flex types. These systems have proven to be effective and economical for our roadside maintenance program. We have experienced a reduction in mowing cycles and difficulty in mowing of Johnson grass. We appreciate the ability to apply herbicide near sensitive crops and farmland without the risk of drift. We are pleased with the construction and reliability of these units and look forward to purchasing more in the future.
