Tiller attachments for full-size skid steer loaders are hydraulic soil conditioning tools designed to break up and aerate the ground. These heavy-duty attachments are ideal for preparing seedbeds, leveling terrain, and mixing compost or amendments. With wider widths and deeper tilling capabilities than mini skid steer versions, they are suited for large-scale landscaping and agricultural applications.
2. Applications
Seedbed preparation for lawns, gardens, or pastures
Soil aeration and weed control
Ground leveling and turf removal
Mixing compost, mulch, or soil amendments
Residential and commercial landscape installation
3. Compatibility
3.1 Mounting System

4. Key Components
Component
Function
Hydraulic Motor
Converts flow into rotational motion for the rotor shaft
Tine Rotor
Shaft with mounted blades that tills and mixes the soil
Replaceable Tines
Curved steel blades for digging, chopping, and mixing
Side Shields
Contain soil within tilling area for a consistent finish
Depth Control Skids
Adjust tilling depth and maintain even ground clearance
Heavy-Duty Frame
Provides rigidity and mounts to loader quick-attach plate
5. Tine and Rotor Options
Tine Style
Use Case
L-Shaped Tines
General-purpose tilling in loose to medium soils
C-Shaped Tines
Better penetration in compacted or clay-heavy soils
Spiral Rotor Layout
Reduces vibration and improves soil flow

7. Operating Guidelines
7.1 Setup
Secure tiller to the skid steer’s quick-attach plate
Connect hydraulic hoses and confirm flow direction
Adjust depth skids according to soil and job requirements
Conduct a short test spin before starting full operation
7.2 Tilling Technique
Start at a low travel speed
Lower tiller to the ground and engage hydraulics
Allow tines to dig and self-propel slightly
Overlap each pass to ensure full ground coverage
Avoid reversing while tines are engaged
8. Safety Best Practices
Wear PPE: gloves, eye protection, steel-toe boots
Keep bystanders at least 10 ft from work zone
Do not clear debris with hands while machine is running
Avoid large rocks, roots, or buried obstacles
Shut off hydraulics before adjusting or performing maintenance
Ensure the tiller matches your skid steer’s quick-attach plate.
Confirm your loader’s hydraulic output to avoid performance issues or damage to the motor.
