Hammer LM40

PART ID: 21006 Hammer LM40

PART ID: 21007 Hammer LM40 with Grapple (shown)

Drives fence posts, sign posts, guard rails, median dividers, tent stakes, T-posts, pipe fence, and railroad ties with ease. Model LM40 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. 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.

CB40 Breaker Kit is available to convert any Hammer post driver into a concrete breaker.
