4. Operating Instructions

Proper operation ensures efficient tilling and prolongs equipment life.

Pre-Operation Checklist:

• Ensure the tiller is securely attached to the tractor's 3-point hitch and PTO shaft.
• Check all bolts and nuts for tightness.
• Verify that the gearbox oil level is correct.
• Inspect tines for wear or damage; replace if necessary.

Tilling Procedure:

1. Start the tractor and engage the PTO at a low RPM.
2. Slowly lower the tiller into the soil using the tractor's hydraulic lift. Adjust the depth as needed, up to a maximum of 4.7 inches.
3. Increase tractor engine RPM to achieve the recommended 540 RPM at the PTO shaft.
4. Drive the tractor forward at a slow, consistent speed, allowing the tiller to thoroughly break up the soil.
5. For optimal results, make multiple passes, gradually increasing depth if desired.
6. When finished, disengage the PTO, raise the tiller, and turn off the tractor engine.
