Red Mountain Prime Post Driver RM57-PD52X with a 1" adapter & carry case & fan cover included

This Red Mountain heavy-duty post driver is built for commercial use and powered by a 1.3 HP 4-stroke engine — no fuel mixing required. Its threaded steel barrel is designed to accommodate posts, pipes, rods, or stakes up to 51 mm in diameter, providing versatile performance across a wide range of applications.
The quick-release spin cap allows for fast and secure adapter sleeve changes. A 1” (25 mm) industrial-grade solid poly adapter sleeve is included as standard.
Additional sleeves are available in ½” and ¾” to match the size of the post or material being driven for optimal efficiency.
Completely self-contained, this post driver requires no external hoses or compressors. It weighs just approx. 16 kg, making it easy to lift, carry, and operate in the field. It drives posts in half the time and with significantly less effort compared to manual drivers.
