The Montana Post Driver T-Rex 350E is a robust excavator-mounted post driver designed for high-production fence building, delivering powerful impact force through its 350-class hammer to drive posts quickly and cleanly in a wide range of soil conditions. Its solid mono-block design eliminates tie rods and reduces vibration, increasing both durability and operator comfort. The 350E typically provides 500–900 blows per minute and can drive large-diameter pipe, railroad ties, H-posts, and heavy structural posts with minimal pilot holes required. Built for long service life, it uses hardened steel components, a heavy front striker plate, and simplified internal engineering to reduce wear and maintenance downtime. The unit pairs with mid- to large-size excavators, allowing operators to take advantage of excellent reach, stability, and visibility for precise post placement. With its hydraulic tilt functionality, quick-attach mounting options, and compatibility with a variety of post-holding tools, the T-Rex 350E offers a dependable, high-output solution for contractors who need speed, accuracy, and reliability on large fencing, construction, and agricultural projects.
