Excavator Post Drivers by TGEC
TGEC designs and builds breaker-converted excavator post drivers for fence installation, T-post driving, sign post work, and agricultural post setting. This attachment is an adapter kit that turns an existing hydraulic breaker into a post-driving tool, using the breaker's impact energy to pound posts into the ground—no separate dedicated hydraulic post driver is required when a compatible hydraulic breaker is already available. We offer six models that cover excavators from 1.5 to 28 tons, paired with breaker classes from 150 kg to 1300 kg, with kit weights ranging from 78 kg to 340 kg and pounding cap diameters from 60 mm to 125 mm. Each kit comes with the post driver body, pounding cap, mounting hardware, and instructions, designed for quick installation onto a compatible breaker without welding or modifications.

Which Configuration Do You Need?
Selecting the right post driver starts with three questions: What excavator are you running? What breaker do you have? What posts are you driving?
Excavator size: Mini machines (1.5–4 t) pair with lighter kits for farm fences and temporary barriers. Mid-size carriers (4–12 t) handle ranch dividers, roadside posts, and commercial fencing. Large excavators (12–28 t) drive heavy guardrail posts and solar farm piles at production speed.
Breaker class: The kit must match your breaker's operating weight — from 150 kg mini hammers up to 1300 kg production breakers. Provide your breaker model, and we'll verify fitment.
Post type and ground conditions: T-posts, round posts, Y-posts, and light steel sections each require specific pounding cap profiles. Soil conditions, from sandy loam to compacted clay, can affect driving resistance and the impact performance required for the application.
Tell us your machine specs and typical fencing application, and our team will recommend the correct TG-PD configuration with a custom bracket drawing for approval.
Our Product Line
Six configurations span 1.5 to 28 ton excavators, paired with breaker classes from 150 kg to 1300 kg. Each kit includes a high-tensile steel mounting frame, a precision-machined pounding cap with replaceable insert, vibration-damping bushings, and all necessary hardware. Custom bracket fabrication can be reviewed for Caterpillar, Komatsu, Volvo, Hitachi, Deere, Kobelco, Hyundai, and other excavator brands. Quick-coupler interfaces are supported across all models.
Application Scenarios
Agricultural fencing and livestock enclosures: Drive T-posts and steel fence posts across open farmland and ranches. The excavator's mobility allows rapid repositioning along long fence lines, while consistent impact energy ensures uniform depth without manual rework.
Farm boundary lines and pasture dividers: Establish property lines and rotational grazing divisions efficiently. Reusing existing breaker equipment makes large-scale fencing operations cost-effective, especially when multiple kilometers of posts are required.
Temporary construction site barriers: Install and remove perimeter fencing around active construction zones. The quick-attach frame allows contractors to switch between post driving and other excavator tasks within minutes.
Roadside guardrail and utility marking posts: Drive posts to precise depths along highways and utility corridors, where controlled positioning is important for safe installation.
Solar farm mounting posts: Install light steel posts for solar array racking systems. Efficient post installation supports large-scale solar projects where consistent placement and project productivity are important.
