Designed with quality and durability in mind, the Flow Gate is used to carry a windrow from the end of the moldboard for longer distances than with a conventional motor grader moldboard. The result is a more even distribution of material, while holding a straighter line when working the shoulder of the road or wherever even distribution of material may be required, including aggregate material and hot asphalt. When used in conjunction with the Bonnell Road Widener, the Flow Gate makes secondary road widening projects a breeze, and because removal is done with just the pull of a pin, your motor grader is ready to go back to work on other project’s without lengthy conversion times.

The all-new 122 Road Maintainer from Bonnell Industries is the little brother of the time-tested, 312 model. The 122’s designers saw a need for a smaller drag that could be towed by a 1/2 ton pick-up or small utility tractor, and that was very maneuverable. We didn’t want to sacrifice quality and ruggedness, however.
The 122 Road Maintainer answers the call for the farmer, park ranger, and/or township supervisor looking to easily maintain their lanes, paths, and secondary roadways.
122 models come standard with serrated blades and a 2 into 1 mixing configuration that creates a level surface. Various options are available, please see our spec sheets for more info!
