Danuser sm40 hammer

Does anyone have any experience running one of these? I have some fencing projects coming up and the qoites i got for high tensile are ridiculous. We did have someone use a similar pounder for one project, so i know they'll work on our ground. Was just curipus if the grapple works as advertised, to make it a one man operation? Would probably have second person laying out posts, but wouldn't have to worry about them getting near/injured with pounder if it works.
