Pilot auger attachment teams up with manufacturer’s HD-10 or HD-12 post driver. Runs on same power source used to operate post driver. Can be installed on companion skid-steer loaders, including tractor- or trailer-mounted machines. Attachment swings into action after driver is positioned, digging a 4-in.-diameter hole where operator plans to install the post. Ideal for expediting post installation in challenging ground, such as clay, gravel or compacted soil. Also reduces wear on post driver. Shaver Mfg., Graettinger, Iowa
