Zahn® Trencher

It Won't Stop Working Until You Do.

Both two-wheel-drive Zahn trenchers are designed to install sprinkler systems and utilities and perform other trenching tasks in traditional fashion with non-traditional power, speed and efficiency. Equipped with a unique InterChange connection that accepts two types of highly productive trenchers, the 2WD R300 deliver superior trenching performance on even the tightest jobsites.

With either four-wheel-drive Zahn trencher you'll experience an unprecedented combination of power, versatility, speed and productivity. Utility contractor, pool builder, rental-yard owner, construction contractor, homebuilder and homeowner, farmer and rancher, landscape professional, and landscape amateur—the 4WD R300 trenchers are dedicated to you.

High-performance Kohler® engine (23 hp/17.1 kW or 30 hp/22.4 kW) enables truly dedicated performance from each front-end trencher.

R300 Trencher

Accepts two types of Zahn trenchers; each concentrates weight on the digging chain so it can penetrate the ground easier.

Optional hydraulic auger that runs independent of the headshaft (patent-pending feature) is standard equipment on 4WD trenchers and optional on 2WD models; this feature reduces the amount of carryover, increasing productivity.

Selectable ground-drive speed ranges enable the operator to choose the optimal speed for different applications.

Two-wheel-drive models accept chains up to 8 inches (203 mm) wide, while the 4WD model accepts up to a 12-inch (305-mm) chain, so you can dig trenches for virtually any application.

Optional Roto Witch® enables boring under sidewalks and other obstacles, reducing jobsite restoration.

Multiple tire options for multiple tasks: 18-inch (457-mm) air-filled tires 18-inch (457-mm) urethane-filled, flat-proof tires 20-inch (508-mm) urethane-filled, flat-proof tires provide heavy-duty performance, maximum stability and minimal tire deflection under load.

Hydraulic drive eliminates maintenance of chains, belts and linkages and allows the use of a reversible digging chain that dislodges rocks and other debris without manual assistance.
