A 3-point post hole digger is a tractor-mounted implement designed to drill deep, uniform holes quickly and efficiently — saving hours of manual work. Whether you’re fencing farmland, installing electrical poles, planting orchard trees, or setting up solar plant supports, the right post hole digger can make the job faster, safer, and more precise.
This guide explains the types of tractor post hole diggers, auger size options, step-by-step hookup, and safe usage — so you can choose the right model for your work. (See our Post Hole Digger attachment here)
⚙️ Types of Tractor Post Hole Diggers
🔄 1. Standard PTO-Driven Post Hole Diggers
The most common and cost-effective design, powered directly by your tractor’s PTO shaft.

General fencing
Agricultural and residential jobs
Light to medium-duty work
Key Features:
Auger sizes from 6″ to 16″
Heavy-duty gearbox
Replaceable auger tips
💪 2. Hydraulic Post Hole Diggers
Hydraulic models are powered through your tractor’s rear hydraulic remotes, offering more torque and control — ideal for hard ground conditions.
Best for:
Rocky or clay-heavy soils
Electrification & construction projects
High-volume commercial digging
Key Features:
High-torque gearbox
Speed and direction control
Optional downforce for tough terrain

🛠️ How to Connect a Post Hole Digger to a Tractor’s 3-Point Hitch
Park Safely – Flat surface, parking brake engaged, engine off.
Attach Lower Lift Arms – Slide arms over hitch pins, secure with lynch pins.
Connect the Top Link – Attach and tighten to the digger’s top mount.
Install the PTO Shaft – Align splines, lock with push-pin or collar; ensure telescoping movement is free.
Check Clearance – Raise/lower hitch to verify auger ground clearance; run PTO at low RPM to test.
⚠️ Safety Tips for Operation
🦺 Always wear gloves, boots, and eye protection
🚫 Never approach a spinning auger
⛔ Shut down tractor before adjustments
👥 Use a second person for alignment where possible
💧 Check soil moisture — avoid digging in overly dry or waterlogged ground
🔍 Troubleshooting Guide
Symptom | Possible Cause | Solution |
|---|---|---|
Auger stalls | Dull teeth, dry soil, wrong gear | Sharpen/replace teeth, moisten soil, correct gear |
Holes not plumb | Top link length, uneven ground | Adjust top link, level digging area |
Excess vibration | Worn bearings, loose bolts, bent auger | Replace bearings, tighten bolts, straighten auger |
PTO chatter | Incorrect PTO angle, short telescoping | Adjust hitch height, correct PTO shaft length |
