• John Deere diesel engine
• High capacity oil system with cooler
• 36” of fore and aft movement
• 245 degree turn table rotation with compact radius
• Zero tail swing eliminates counterweight overhang
• Standard heavy-duty post puller
• Drop hammer weight ranges from 1,000-2000 lbs.
• Optional hydraulic impact hammer available
• Optional auxiliary drill attachment available
• Will accept up to 10”x10” wood post with standard foot

Small Track Post Driver

GRT Utilicorp Inc. is proud to announce the introduction of the UTRTPD-10-15 track-mounted post driver. The machine is mounted on a heavy-duty rubber track assembly, making it one of the most versatile post drivers ever offered by GRT Utilicorp, Inc. The unit boasts a reliable and powerful Kubota diesel engine, a high capacity oil system and powerful vibratory demolition-style hammer to drive posts in even the toughest conditions. Fore and aft movement, as well as boom leveling capabilities, GRT Utilicorp, Inc. also leaves the option open to add a pneumatic rock drill assembly or side mounted auger drill.

One of the most exciting features of the track-mounted post driver is its compact size. The machine is capable of driving a post that is 15 feet tall. Its compact size also allows the suitable option of transporting with a pick-up truck and equipment trailer. The compressed size and off-road capabilities of the UTRTPD-10-15 allows the machine to work in smaller areas, thus reducing lane closures in ideal conditions and also making it ideal for use installing solar panels in the push to become a more environmentally-mindful society.
