Guide to Bobcat Augers Attachments & Implements

What is an Auger?

An auger is a mechanical tool designed to drill precise, cylindrical holes into the ground. Its defining feature is a spiral-shaped shaft (often referred to as a flighting) that rotates to displace soil upward and out of the hole. This continuous movement allows for efficient excavation with minimal disruption to the surrounding area. 

Augers are used across a wide range of industries where ground penetration is required. The design of an auger enables consistent hole depth and diameter, making it ideal for tasks such as:

• Installing structural supports (e.g., fence posts, signposts, footings) 
• Planting trees and shrubs with uniform root ball cavities 
• Sampling soil  for agricultural or environmental analysis 
• Accessing underground utilities for maintenance or installation  

The auger’s effectiveness depends on its configuration (bit type, diameter, and drive system) all of which can be tailored to match specific soil conditions and jobsite requirements. 

What is an Auger Attachment?

An auger attachment is a hydraulically powered attachment that connects to the front of compact equipment such as skid-steer loaders, compact track loaders, compact (mini) excavators and more. When paired with a host machine, the auger attachment transforms it into a high-performance drilling system capable of handling a wide range of ground conditions, from loose topsoil to dense clay and even asphalt. 

Bobcat auger attachments are engineered for durability and precision. They feature:

• Planetary Gear Drives -- That deliver consistent torque for demanding applications 
• Multiple Output Configurations (available in hex and round) -- To accommodate different bit types: 
• Hex – 2" and 2.5” 
• Round – 2.5” 
• Combination – 2" Hex and 2.5” Round 
• Quick-Change Mounting Systems -- For fast transitions between tasks to maximize productivity on the jobsite. 

These attachments are not just add-ons—they’re productivity multipliers. Whether you're building a fence line across a rocky pasture, installing footings for a deck, or planting trees in a landscaped park, the auger attachment ensures consistent performance and clean results. 

What Is An
Auger Implement?

An auger implement is a rear-mounted drilling tool designed for use with tractors, like sub-compact, compact and utility tractors, and rear-compatible utility machines, such as the Bobcat UW53 Toolcat ®. Unlike front-mounted auger attachments, auger implements connect to the three-point hitch or rear hydraulic system, allowing operators to drill holes while driving in reverse or stationary. 

Auger implements are commonly used in: 

• Agricultural settings: For fencing, pole barns, planting and more 
• Rural construction: For signposts, foundational footings and more 
• Land management: For tree planting, erosion control, soil sampling and more

Bobcat auger implements are built to handle a variety of soil conditions and are compatible with a range of bit sizes. They offer:

• Robust gearboxes for consistent torque 
• Heavy-duty frames for long-term durability 
• Adaptable mounting options for compatibility with different tractors and utility vehicles

These implements are ideal for operators who prefer rear-mounted tools or need to maintain front loader functionality while drilling. They’re especially useful in open-field environments where maneuverability and rear access are advantageous. 

What Do “PH”, and “PC” Mean on the Auger Model Names?

Bobcat auger models are categorized by their drive type, which determines how torque is delivered to the auger bit and how the attachment performs under different soil conditions. Understanding these designations is key to selecting the right model for your jobsite needs. 


• Planetary Hex (PH): Provides a full range of torque and speed options, allowing for both high torque and low torque as well as high speed and low speed operation.
  
• Planetary Combination (PC): By incorporating both hex and round features on the output shaft, this engineered design delivers versatile performance with both high and low speeds, along with high and low torque capabilities, plus making it suitable for a variety of diverse digging tasks and operations.
 

Planetary Hex (PH) and Planetary Combination (PC) have the models to match your specific needs.  

Compatible Versatility

Bobcat augers are engineered for broad compatibility, offering versatile operation across a diverse range of equipment. The 20PH and 20PC Augers, for instance, can be used seamlessly with any Bobcat excavator from the E35 to the E60 models, as well as with Bobcat skid-steer and compact track loaders ranging from the S64-2/T64-2 up to the S86-2/T86-2. This cross-platform compatibility means operators can tackle a variety of projects without worrying about matching specific auger models to individual machines.

Whether attached to compact excavators or larger skid-steer and track loaders, Bobcat augers adapt easily for different tasks and environments. This flexibility not only maximizes equipment utilization but also streamlines workflows for crews managing multiple machine types on a job site. 

Auger Bit Sizes

Bobcat augers are engineered for broad compatibility, offering Bobcat augers support a wide range of bit sizes and diameters; each recommended to specific auger models and digging conditions. Choosing the correct bit size is essential for achieving consistent hole depth, clean edges, and efficient material displacement.

Use the guide below to match bit sizes to auger families and typical applications.

Bit Sizes Offered 

• 6-36 Inch Bits: For 12-30 PH/PC. 
• 8-48 Inch Bits: For 35PH & 50PH. 


Recommended Pairings (Average Conditions) 

• 12PH/PC: 6–18 in 
• 14–30 PH/PC: 6–36 in 
• 35PH & 50PH: 8–48 in 


Note: Recommendations are guidelines based on average digging conditions. Actual selection may vary by soil composition, hole depth, bit style, and machine configuration. For project specific guidance, contact your local Bobcat Dealer.
