Detailed Comparison
1Productivity Comparison
The Double Digger delivers nearly twice the productivity of a Single Digger by digging two holes simultaneously. In an 8-hour workday, the Double Digger can complete 500-800 holes compared to 250-400 holes with the Single Digger. For large-scale projects like solar farms or highway fencing with thousands of holes, this productivity difference translates to significant time and cost savings.
2Tractor Requirements
The Double Digger requires a more powerful tractor (55-90 HP) due to its dual auger system. The Single Digger works well with tractors from 35 HP onwards, making it suitable for farmers with smaller tractors. If you already own a high-HP tractor, the Double Digger can maximize its utilization.
3Versatility & Applications
The Single Digger offers more versatility with auger sizes ranging from 9" to 24", suitable for everything from fence posts to large tree planting. The Double Digger is optimized for projects requiring many uniform holes at fixed spacing. The Single Digger is better for varied applications on a single farm.
4Cost & ROI Analysis
The Double Digger has a higher upfront cost but delivers faster ROI for commercial operations. For a contractor doing regular large projects, the Double Digger pays for itself within 3-4 projects. The Single Digger is more economical for farmers who need occasional pit digging throughout the year.
5Terrain & Maneuverability
The Single Digger is lighter and more maneuverable, making it ideal for orchards, uneven terrain, and tight spaces. The Double Digger requires more space to operate and works best on relatively flat, open land. For projects with obstacles or irregular layouts, the Single Digger offers more flexibility.
When to Choose Double Digger
- Large-Scale Commercial Projects
Solar farms, highway fencing, railway projects with 1000+ holes.
- Contract Work
Professional contractors who bid on large digging projects regularly.
- Time-Critical Projects
When project deadlines are tight and speed is essential.
- Uniform Hole Spacing
Projects requiring consistent spacing (adjustable 2-4 feet between holes).
When to Choose Single Digger (Post Hole Digger)
- Farm & Agriculture Use
Regular farming needs like tree planting, fencing, and general pit digging.
- Smaller Tractors (35-50 HP)
If you have a smaller tractor that cannot power the Double Digger.
- Varied Applications
Need different hole sizes (9" to 24") for various applications.
- Uneven Terrain
Orchards, slopes, or areas with obstacles requiring maneuverability.
- Budget-Conscious Buyers
Lower initial investment while still getting professional-grade equipment.
Our Verdict
For most farmers and small-scale users, the Single Digger (Post Hole Digger) is the better choice due to its versatility, lower tractor requirement, and lower cost. For contractors, solar installers, and large-scale commercial operations, the Double Digger delivers superior productivity and faster project completion that justifies its higher cost. If you do 3-4 large projects per year with 500+ holes each, the Double Digger will pay for itself quickly.
Frequently Asked Questions
Can I use the same augers on both machines?
The 12" and 18" augers are compatible with both machines as they use the same shaft connection. However, the Double Digger requires two matching augers, while the Single Digger uses one auger.
Which has lower maintenance costs?
The Single Digger has lower maintenance costs as it has one gearbox instead of two. However, both machines use the same high-quality components with similar service intervals.
Can I upgrade from Single to Double Digger later?
The machines are separate units, so upgrading means purchasing a new Double Digger. However, we offer trade-in value for your existing MMS equipment. Many customers keep both for different applications.
Is operator training different for both machines?
The basic operation is similar for both machines. If you can operate a Single Digger, you can easily operate a Double Digger with minimal additional training. We provide free training with every purchase.
What if my project needs vary throughout the year?
For varied needs, many professional contractors own both machines. The Single Digger for routine farm work and tight spaces, the Double Digger for large commercial projects. This combination maximizes versatility and productivity.
