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!
