HAMMER SM40 WITH GRAPPLE

Drives fence posts, signposts, guard rails, median dividers, tent stakes, T-posts, pipe fence, and railroad ties with ease. Model SM40 has a 40” drop hammer design. 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. The 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.

 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. See Accessories tab below.
