Backhoe attachments transform skid steer loaders into powerful digging machines capable of performing a wide variety of light to medium-duty excavation tasks. Designed for precise trenching and digging operations, they replicate the motion of a traditional backhoe with the convenience of a compact skid steer platform.

4. Key Components
Component
Function
Boom Arm
Provides vertical lift and digging depth
Dipper Stick (Dip Arm)
Controls horizontal reach and movement of bucket
Bucket (Various sizes)
Scoops and moves soil, gravel, debris, etc.
Hydraulic Cylinders
Provide movement for boom, dipper, and bucket
Mount Frame / Subframe
Connects attachment to the skid steer’s mounting plate
Stabilizer Legs (optional)
Provide support and reduce machine movement during digging
5. Bucket Options
Bucket Size
Application
9″ – 12″
Narrow trenching (irrigation, utility lines)
16″ – 18″
Versatile general digging
24″ – 36″+
Heavy excavation and wide trenching
Grading / Tilt Buckets
Slope shaping, finishing work
Buckets often feature replaceable teeth for durability and efficiency.
6. Operation Guidelines
6.1 Setup
Attach the backhoe securely to the skid steer’s quick attach plate.
Connect hydraulic hoses—ensure correct flow direction and compatibility.
Verify bucket and pin connections are tight and in good condition.
Test hydraulic functions before engaging in work.
6.2 Digging Technique
Lower the boom and engage the bucket into the soil.
Use dipper stick to draw the bucket back through the material.
Curl the bucket to scoop, then lift using the boom.
Dump material to the side or into a container, repeat as needed.
Use stabilizers or skid steer weight for better balance when digging.
7. Safety Protocols
Wear PPE: hard hat, gloves, safety glasses, and steel-toe boots
Keep bystanders and crew members clear of the digging area
Operate only on level ground or use stabilizers if available
Never exceed load limits of the backhoe or the skid steer
Always disengage hydraulics and relieve pressure before maintenance
8. Maintenance Checklist
Task
Frequency
