Product Overview
The TGEC excavator hydraulic post driver is a breaker-converted attachment in the Excavator Post Drivers range, built for fence installation, T-post driving, sign post work, and agricultural post setting. Unlike dedicated post drivers that come with their own hydraulic motor, this one is an adapter kit that bolts onto your existing hydraulic breaker and turns it into a post-pounding machine. You pull the breaker's standard chisel, slide on the guide tube and pounding cap assembly, and the breaker's piston does the rest—hammering the cap to drive posts straight into the ground. It leverages the breaker's existing hydraulic circuit and impact guts, so you get the power you need without the cost and complexity of a separate attachment.
We offer six models that cover excavators from 1.5 tons all the way up to 28 tons, with matched breaker classes from 150 kg to 1300 kg. The TG-PD80 is the compact option for mini excavators and small breakers—60 mm pounding cap, 78 kg kit weight, perfect for light fence and T-post work. The TG-PD120 and TG-PD160 step up to medium-duty mini excavators with 75 mm and 85 mm caps. The TG-PD220 and TG-PD280 are built for full-size machines with 95 mm and 110 mm caps for heavier posts. And the TG-PD350 is the big dog—125 mm cap for large-diameter posts on 20–28 ton excavators. Every kit includes the driver body, pounding cap, mounting hardware, and clear instructions. No welding, no modifications—just bolt it on and go.

How It Works
The TGEC excavator hydraulic post driver works by turning your existing breaker into a post-pounding attachment. You pull the breaker's standard chisel or tool, then install the post driver kit—guide tube, pounding cap, and mounting hardware—in its place. When you fire up the breaker, its hydraulic piston slams into the pounding cap at the top of the guide tube, transferring that impact energy straight down through the cap to the top of the post sitting below. The guide tube keeps the post lined up and prevents the cap from glancing off, so all that energy goes right down the post axis. The operator controls impact frequency and force using the breaker's existing cab controls, so you can dial it in for different posts, soil conditions, and depths. Once the post is set, you stop the breaker, lift the attachment, and move to the next one.
Application Scenarios
Fence installation: Drive wooden, steel and vinyl fence posts for agricultural, residential and commercial fencing projects.
T-post installation: Drive steel T-posts for agricultural fencing, wildlife management and erosion control.
Sign post installation: Install steel sign posts for road signs, property markers and directional signage.
Agricultural post work: Drive posts for livestock fencing, crop protection, barn construction and farm infrastructure.
Landscaping: Install posts for landscape edging, tree support and garden structures.
Construction fencing: Drive posts for temporary construction fencing, site security and perimeter control.
Municipal work: Install posts for traffic control, utility markers and public infrastructure projects.
Installation & Mounting
Getting the post driver on your excavator is straightforward. Start by removing the breaker from the excavator's boom or quick coupler, then pull the standard chisel or tool out of the breaker's front head. Mount the post driver kit—guide tube, pounding cap, and hardware—onto the breaker's front head in place of the chisel, using the provided bolts and instructions. Make sure the guide tube and cap align properly with the breaker piston so impact energy transfers cleanly. Once the kit is snug on the breaker, reattach the breaker to the excavator and reconnect the hydraulic hoses to the auxiliary circuit. Before you start driving, double-check that the kit is secure, the cap is aligned with the tube, and the breaker cycles properly with the driver installed. The whole job usually takes 15–30 minutes with basic hand tools, and you can pull the kit off just as fast to switch back to demolition work.
Wear & Service
The main wear parts on the post driver are the pounding cap, the guide tube, and the mounting hardware. The pounding cap takes a beating from the breaker piston—check it regularly for flattening, cracking, or deformation, and ｒｅｐｌａｃｅ it when it starts to lose shape or causes the post to drive crooked. The guide tube can get bent or worn at the post entry point; if it's damaged, swap it out to keep posts straight. Keep an eye on the bolts, pins, and clips that hold everything together—tighten or ｒｅｐｌａｃｅ them if they get loose or worn. Your hydraulic breaker still needs its regular maintenance too: grease the front head and bushings, change hydraulic fluid and filters on schedule, and check the piston and seals. Since the post driver mounts to the breaker, any wear on the breaker's front head or tool retainer can mess with the driver's fit and performance, so stay on top of that as well.
Dealer & Bulk Orders
TGEC supplies excavator hydraulic post drivers to fence contractors, agricultural equipment dealers, construction rental companies, municipal maintenance departments, and OEM partners worldwide. We offer dealer and bulk-supply programs based on model selection, order volume, breaker compatibility, and project needs. OEM and private-label arrangements can also be explored based on partner requirements and production feasibility.
