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˚ left or right. The hammer weight is 300 lb. from the factory. Additional weight can be added for a total of 500 lb.
