Stop Adding Gravel. Start Reclaiming It.

Anyone can spread fresh gravel.

Professionals know the smarter solution is reclaiming the material that's already there.

The Mammoth Land Planer breaks apart washboards, potholes, and compacted areas while pulling existing gravel back into low spots. Instead of simply pushing material around, it restores the surface to create a smoother finish, improve drainage, and reduce future maintenance.

Perfect for:

• Gravel Driveways
• Private Roads
• Horse Arenas
• Parking Lots
• Building Pads
• Landscaping Projects
• Farm Lanes
• Seedbed Preparation

One Attachment. Multiple Jobs.

The Mammoth Heavy-Duty Land Planer is designed to replace several grading tools while producing professional-quality results.

It allows you to:

✔ Cut down high spots

✔ Fill potholes

✔ Eliminate washboards

✔ Break up compacted surfaces

✔ Redistribute gravel

✔ Screen oversized rocks and debris

✔ Leave a smooth finished grade

Less time grading means lower operating costs and more jobs completed each day.

Adjustable Scarifiers Do the Hard Work

Loose gravel is easy.

Hard-packed driveways are where this attachment shines.

The adjustable scarifier teeth penetrate compacted surfaces before the grading edge levels the material. Instead of riding over hard-packed gravel, the scarifiers loosen the surface so the planer can reshape it correctly.

When they're eventually worn, the teeth are fully replaceable, helping keep maintenance costs low.
