Earth augers for Jansen earth auger machines—the right auger for every application
With the right earth auger, earth auger machines operate efficiently, cleanly, and with minimal effort. Whether for fence construction, planting, foundation holes, or agricultural applications—the auger diameter determines how quickly and precisely the desired result is achieved. In this category, you’ll find genuine earth augers for various Jansen earth augers and tractor-mounted augers in a wide range of diameters from 80 to 600 mm.
All auger bits are designed to fit the respective Jansen models and allow for quick changes, so the auger can be flexibly adapted to different tasks.
Which auger is right for your project?
The appropriate auger diameter depends primarily on the intended use. While smaller augers work with particular precision and displace little soil, larger augers allow for the quick creation of foundation or planting holes.
- 80 mm: ideal for smaller stakes, rods, or ground anchors.
- 150 mm: suitable for fence posts, drive-in sleeves, and smaller planting jobs.
- 200 to 250 mm: a good choice for sturdier posts, smaller foundations, or larger plants.
- 225 to 300 mm: frequently used for fruit trees, shrubs, foundations, and gardening and landscaping.
- 450 to 600 mm: suitable for large planting holes, extensive foundation work, or particularly large volumes of soil.
With different auger diameters, an existing earth auger can be used for a wide variety of projects without the need for an additional machine.
Compatible augers for various Jansen auger drills
The augers in this category are specifically designed for different Jansen machines. This ensures that the mounting, length, and design are optimally matched to the respective auger drill.
Augers for single-operator auger drills
For the Jansen EBG-100 one-man earth auger, auger bits with diameters of 80, 150, 250, and 300 mm are available. These are particularly suitable for work around the house, in the garden, and for smaller construction projects.
Earth augers for tractor-mounted augers
Auger bits in various sizes ranging from 150 to 600 mm are available for the Jansen TBG series. They are suitable for regular use in agriculture, landscaping, or fence construction.
Earth augers for hydraulic earth auger rigs
For hydraulic models such as the Jansen HBG-5000, auger bits with large diameters are available. They are used wherever high drilling performance and larger hole diameters are required.
Frequently Asked Questions About Augers
Which auger is suitable for fence posts?
For most fence posts, augers with a diameter of 150 or 200 mm are used. The appropriate size depends on the post diameter and the foundation.
What auger sizes are available?
Depending on the model, earth augers are available in diameters ranging from 80 to 600 mm. This allows for drilling both small planting holes and large foundation holes.
Do all earth augers fit every Jansen earth auger drill?
No. The augers are each designed for specific one-person, tractor-mounted, or hydraulic auger rigs. Compatibility should be checked before purchasing.
What auger size is suitable for trees?
For smaller trees, 225 or 300 mm are often used. Larger trees require a diameter of 450 or 600 mm, depending on the root ball.
Can I change the auger myself?
Yes. The augers can be changed in just a few simple steps on compatible Jansen auger drills, allowing different tasks to be completed quickly.
When is a large auger worth it?
Large auger diameters are suitable for foundations, large planting holes, or jobs involving heavy-duty excavation. A sufficiently powerful auger is required.
Are there replacement parts for Jansen augers?
Suitable replacement parts are available for numerous machines and attachments. This allows wear parts to be replaced as needed and ensures long-term operational readiness.
Robust construction for heavy-duty use
Earth augers are subjected to high forces during operation. Rocks, compacted soil, or roots place high demands on materials and workmanship. Jansen auger bits are designed to withstand these stresses and feature a sturdy construction as well as smooth power transmission to the auger.
Depending on soil conditions, it is recommended to pause the drilling process regularly and clear the borehole of loosened soil. This allows the auger bit to operate more efficiently and helps preserve the equipment.
What should you look for when buying an auger?
In addition to the desired diameter, compatibility with your existing auger plays a crucial role. Since mounting systems and designs can vary, the auger should always be selected to match the specific JANSEN model.
- the correct diameter for the intended application
- compatible with your existing Jansen earth auger
- sufficient drilling power of the machine for larger diameters
- Consider soil conditions and potential obstacles
