A skid steer loader post hole digger is an attachment used with a skid steer loader that allows the operator to efficiently drill holes into the ground for various purposes, such as setting fence posts, planting trees, or installing signposts. The attachment typically features a rotating auger bit that can dig into the soil, making it easier to create deep and narrow holes.

### Features of a Skid Steer Loader Post Hole Digger:
1. **Auger Bit**: The digger has a drill bit (auger) that comes in various sizes, allowing for different hole diameters.
2. **Hydraulic Drive**: The auger is powered by the skid steer’s hydraulic system, enabling it to bore through various soil types.
3. **Adjustable Depth**: Many models allow you to control the depth of the hole being dug, which is essential for different applications.

### How to Use a Skid Steer Loader Post Hole Digger:

1. **Preparation**:
– **Choose the Right Auger Bit**: Select an auger bit size appropriate for your project.
– **Locate the Site**: Mark the spots where you need to dig holes.
– **Check for Utilities**: Before digging, ensure that there are no underground utilities in the area.

2. **Attach the Digger**:
– **Connect the Attachment**: Use the skid steer’s coupler system to securely attach the post hole digger to the machine. Ensure it is locked in place.

3. **Position the Skid Steer**:
– **Align the Auger**: Drive the skid steer to the marked spot and position the auger directly over the intended hole.

4. **Control the Digger**:
– **Lower the Auger**: Use the skid steer’s joystick controls to lower the auger into the ground.
– **Engage the Auger**: Activate the hydraulic controls to start the auger rotating. The auger will begin to dig into the soil.
– **Monitor Depth**: Keep an eye on the depth of the hole as it is being dug. Pull up periodically to remove soil buildup from the auger.

5. **Complete the Hole**:
– **Dig to Desired Depth**: Continue to operate the auger until you reach the desired depth.
– **Raise the Auger**: Once the hole is ready, slowly raise the auger back out of the hole.
– **Remove Soil**: Clear away any soil that has been excavated from around the hole.

6. **Post-Installation**:
– **Set the Post**: After digging, you can place the post in the hole. Make sure it is level and straight before securing it (e.g., pouring concrete or backfilling with dirt).

7. **Cleanup**:
– **Unattach the Digger**: After you’re done, disconnect the post hole digger from the skid steer.
– **Store the Equipment**: Clean and store the auger and skid steer as per standard operating procedures.

### Safety Tips:
– Always wear appropriate personal protective equipment (PPE), such as hard hats, gloves, and eye protection.
– Be aware of your surroundings and maintain a safe distance from other workers and equipment.
– Ensure that the area is clear of debris and obstacles before operating the skid steer.

Using a skid steer loader post hole digger can significantly increase efficiency and reduce physical labor when digging holes for construction or landscaping projects.
