Designed for small excavators, the Autoguide Midi-Postmaster Post Driver from Seago International is designed to install driving posts accurately.
The Midi-Post Master works best with 2.5- to 5-ton mini-excavators (flow rate of 9-12 GPM) and will drive posts up to 8-inches in diameter.
Weighing in at 430 pounds, the model delivers 13,500 foot-pounds of downforce at 50 Hertz.
Hydraulic post clamps secure the post for positioning. For best results, operators can vibrate the post into the ground to get more accurate results.
