A heavy-duty attachment for motor graders used to break up compacted soil, asphalt, or other hard surfaces.
Technical details and manufacturing context for Scarifier
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Ripper Shank Count | 3–5 | More shanks for harder material |
| Ripper Shank Spacing | 300–500 mm | Affects breakout force distribution |
| Maximum Penetration Depth | 300–600 mm | Depth depends on material hardness |
| Breakout Force | 100–300 kN | Higher force for compacted asphalt |
| Operating Weight | 1500–4500 kg | Heavier for stability |
| Material Grade | HG70–HG80 | High-strength steel for wear resistanceGB/T 16270 |
| Hardness | 45–55 HRC | For shank tips |
| Operating Temperature | -20–60 °C | Below -20°C steel becomes brittle |
| Mounting Width | 1500–3000 mm | Must match grader moldboard width |
| Pin Diameter | 50–80 mm | For attachment to grader |
| Hydraulic Flow Rate | 60–120 L/min | Required for ripper operation |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

A scarifier is used on motor graders to break up compacted soil, asphalt, or other hard surfaces before grading or new construction. It fractures the material to create a workable base.
Scarifier teeth are typically made of high-carbon steel or alloy steel, with a hardness range of 45-55 HRC for the shank tips to resist wear.
The scarifier is attached to the motor grader via a mounting frame with pin connections. The mounting width and pin diameter must match the grader's specifications, typically 1500-3000 mm and 50-80 mm respectively.
Key parameters include operating pressure (1.0-1.6 MPa), ripper shank count (3-5), spacing (300-500 mm), maximum penetration depth (300-600 mm), breakout force (100-300 kN), operating weight (1500-4500 kg), material grade (HG70-HG80), hardness (45-55 HRC), operating temperature (-20 to 60°C), mounting width (1500-3000 mm), pin diameter (50-80 mm), and hydraulic flow rate (60-120 L/min). Always confirm these with the manufacturer for your specific model.
