Post Drivers

Danuser’s post-driving lineup covers everything from T-posts to railroad ties with simple, high-output attachments. The Hammer SM40 uses a 300-lb drop weight and a full 40" stroke to deliver up to 1,025 ft-lb per strike (1,709 ft-lb with the optional weight kit), achieving as many as 35 strokes per minute. The SM40 also offers a grapple for true one-person operation, ±20° tilt for contour work, and the weight kit that increases total hammer mass to 500 lb for harder ground and larger posts. With only 12–30 GPM of hydraulic flow required at 1,500–3,000 PSI, it's built to be easy to run and flexible for a variety of posts, with repeatable driving performance and minimal maintenance.

For fencing crews focused on steel T-posts and light pipe, the compact T3 hydraulic driver is a versatile, lower-weight option. It drives posts up to 3" O.D. at up to six strikes per second, with 2,000 lb impact force and 40 ft-lb per stroke, mounting to tractors, skid steers, and loaders. A fully contained strike zone protects the post top and prevents kick-out, with a built-to-last design to handle years of use.
