Home \ Products \ Hydraulic Post Driver \ NEW PD400 Post Driver NEW PD400 Post Driver The Premier Attachments PD400 Post Driver is designed for operators who need flexibility without complexity. Built around a modular, bolt-on platform, the PD400 lets you configure the driver to match your job today and easily adapt it as your needs change. The PD400 starts as a ready-to-run post driver with a standard skid steer mount. Its 4-bolt mounting pattern allows the driver to be positioned left, center, or right, giving you better visibility, reach, and working clearance. Optional high-reach and side-reach extensions use the same mounting pattern and can be run individually or combined to extend the driver up, out, or both. More than just a post driver, the PD400’s platform design allows additional configurations, including the option to add an auger drive. Run a post driver and auger on the same mount or configure it as a dedicated auger setup. One attachment, multiple solutions. Designed for real-world jobsite use, the PD400 includes a welded access step, spring hose holder kit, and Premier’s signature orange finish, with black modular accessories for easy identification. It drives up to 4x4 posts, T-posts, and pipe, features a 5-1/2” ID cup, and is backed by a 2-year warranty. Mount options are available for skid steers, tractors (global, John Deere, compact tractor, etc.) excavators, and Premier’s Duo-Tach® system. The PD400 isn’t a fixed tool, it’s a modular system. Start simple, add accessories as needed, and reconfigure as the job demands.
