Setup and Assembly
Proper setup is crucial for the safe and effective operation of your chisel plow. Follow these steps carefully:
- Unpacking and Inspection: Carefully remove all components from the packaging. Inspect for any shipping damage. Report any damage to your dealer immediately.
- Attaching to Tractor: Ensure the tractor's drawbar is compatible with the plow's hitch. Securely attach the plow to the tractor's drawbar using the appropriate hitch pin and safety clip. Verify all connections are tight.
- Hydraulic Connections: Connect the plow's hydraulic hoses to the tractor's hydraulic outlets. Ensure connections are clean and free of debris. Check for proper fluid levels in the tractor's hydraulic system.
- Depth Adjustment: Adjust the plow's depth control mechanism according to the desired tilling depth. Refer to the specific instructions for your model's depth adjustment system.
- Tine Installation (if applicable): If tines are not pre-installed, attach them securely to the plow frame using the specified hardware. Ensure proper spacing and orientation.
Operating Instructions
Before operating, ensure all safety checks are complete and you are familiar with the tractor and plow controls.
- Pre-Operation Checklist:
- Check tire pressure on both tractor and plow.
- Verify all bolts and fasteners are tight.
- Ensure hydraulic hoses are free from leaks and properly connected.
- Confirm all safety shields and guards are in place.
- Engaging the Plow: Slowly lower the plow into the soil using the tractor's hydraulic controls. Begin tilling at a moderate speed, gradually increasing as conditions allow.
- Adjusting Depth and Speed: Monitor the tilling depth and adjust as needed. Optimal operating speed will vary based on soil type, moisture content, and desired results. Avoid excessive speed which can lead to poor tilling and increased wear.
- Turning: When turning at the end of a pass, raise the plow completely out of the ground to prevent damage to the tines and frame.
- Disengaging: When finished, raise the plow completely, disengage the tractor's PTO (if applicable), and park the equipment on a level surface.
Maintenance
Regular maintenance is essential for the longevity and reliable performance of your chisel plow.
- Daily Checks:
- Inspect tines for wear or damage. Replace worn tines promptly.
- Check for loose bolts and tighten as necessary.
- Clean soil and debris from the plow frame.
- Weekly/50-Hour Maintenance:
- Lubricate all grease points as indicated in the lubrication chart (refer to the full manual for details).
- Inspect hydraulic hoses and fittings for leaks or damage.
- Check tire pressure and condition.
- Seasonal/Annual Maintenance:
- Thoroughly clean and inspect the entire plow.
- Repaint any areas where paint is chipped to prevent rust.
- Store in a dry, protected area during off-season.
Troubleshooting
This section addresses common issues you might encounter during operation.
| Problem | Possible Cause | Solution |
|---|---|---|
| Plow not penetrating soil | Incorrect depth setting, worn tines, hard soil conditions | Adjust depth, replace tines, increase down pressure (if applicable) |
| Uneven tilling depth | Uneven ground, improper leveling, tire pressure differences | Level plow, check tire pressure, adjust hitch |
| Excessive vibration/noise | Loose components, damaged tines, worn bearings | Inspect and tighten all fasteners, replace damaged parts, check bearings |
