The landscape curb trencher is an ideal choice for larger curbing assignments such as parking lots, wheel blocks and a wide range of commercial installations that are filled through a concrete truck. Incorporating a 9 in. wide curbing rotor, this Viper HD+ is capable of cutting a trench measuring 4 in. deep and 9 in. wide even in the hardest clays. It features steerable wheels that make tree rings and fancy curves easily.
