Weight: 915lbs
Danuser Hammer
Model SM40 has a 40” drop hammer design with up to 35 strokes per minute. With this innovative design, you can achieve a full stroke with every cycle or utilize the short stroke feature to fine tune your depth. The Hammer DOES NOT operate with springs, hydraulic cylinder, or return line. Grapple option can be added to any model for a true one-person operation (does not include t-posts). The grapple option will allow the operator to grab the post off the ground, load it into the machine, and drive it in the ground without leaving the skid-steer seat. Tilt option allows up to 20˚ in each direction. The hammer weight is 300 lbs. from the factory. Additional weight can be added for a total of 500 lbs. The unit also has an integrated post puller to be used with log chain.
NOTE: If post/pipe diameter is 5″ or smaller and you have a helper, PN 21395 Donut Strike Plate must be purchased separately. If driving with one person, PN 21212 Horseshoe Strike Plate is a better option.
