Three power units with a set of compatible front ends are designed to provide dedicated performance: the Zahn R150 trencher in the 15-hp class; the Zahn R230 power unit, available in two-wheel and four-wheel models; and the Zahn R300 power unit. The R300 comes in two versions – the two-wheel-drive machine powers two types of front-end trenchers, while the four-wheel-drive accepts up to seven types of front ends: trencher, plow, dumper, tiller, backhoe, stump grinder, and a tool carrier that can drive more than 40 quick-change attachments.
