Fence Installation with Mini Excavators
Install fences faster with a mini excavator and auger. Learn about post hole drilling, gate access, and the right equipment for fence contractors.
Quick Answer
For fence installation, use a 1-ton mini excavator with 9-12" auger. It fits through 36" gates and drills 50+ post holes per day. A thumb attachment helps position posts. ROI typically comes within one season.
Fence installation is one of the most profitable applications for mini excavators. With an auger attachment, a single operator can drill 50+ post holes per day—work that would take a crew days by hand.
Post Hole Drilling
**Auger Selection** Match auger diameter to post size: - 4x4 wood posts: 9-12" auger - 6x6 wood posts: 12-18" auger - Metal posts: 6-9" auger - Concrete footings: 12-24" auger
**Drilling Speed** A mini excavator with auger can drill a 12" diameter, 3-foot deep hole in 2-3 minutes in average soil. Rocky or clay conditions take longer but are still far faster than manual digging.
Gate Access Matters
Fence contractors work in backyards. A 1-ton mini excavator that fits through 36" gates accesses virtually any property. The H15R even offers adjustable track width for extra-tight access.
Complete Fence Workflow
1. **Layout** - Mark post locations 2. **Drill** - Auger all holes first 3. **Set posts** - Use excavator to position and plumb 4. **Concrete** - Pour around posts 5. **Install** - Attach rails and pickets
Equipment Recommendations
For fence contractors, a 1-ton mini excavator with auger offers the best combination of access, capability, and value. Add a thumb for handling materials and a trailer for transport.
Frequently Asked Questions
How fast can a mini excavator dig post holes?
A mini excavator with auger can drill 50-100 post holes per day depending on soil conditions. Each hole takes 2-3 minutes versus 15-20 minutes manually. ROI typically comes within one season for active fence contractors.
What size auger do I need for fence posts?
Use a 9-12" auger for 4x4 posts, 12-18" for 6x6 posts. The hole should be 3-4 inches wider than the post for concrete. For chain link posts, 6-8" is sufficient.
