New Zealand farms and rural properties maintain extensive gravel roads, paddocks, and access tracks. Regular use causes washboarding, potholes, and soil compaction. A skid steer hydraulic land plane scarifier combines ripping, grading, and debris removal in one attachment. New Zealand agricultural operations, landscapers, and rural contractors use these tools for efficient ground maintenance. This equipment serves properties needing to maintain roads, prepare seedbeds, and level uneven terrain. The country’s diverse landscape, from volcanic plateaus to sedimentary plains, requires versatile ground preparation tools that adapt to varying soil conditions.
Technical Overview and Ground Preparation Applications
The attachment measures 72 inches working width. Eight heavy-duty ripper teeth break compacted ground, controlled by a hydraulic cylinder for raise and lower operation. Maximum ripper depth reaches 4 inches. A reversible planer comb with NM400 steel construction shapes and levels material. NM400 steel is a abrasion-resistant grade that withstands impact from rocks and hard-packed soil, extending component life significantly compared to standard steel. Fixed sift screen trays measure 1.5 by 3 inches, capturing rocks, roots, and debris. The unit carries up to 1100 pounds on top for moving materials such as gravel bags or small buckets. Universal skid steer mount fits most makes and models, including Bobcat, Caterpillar, and John Deere. Product operating weight is 780 pounds.
Ground preparation applications include gravel road repair for farm access, paddock renovation for pasture seeding, garden bed preparation for planting, driveway maintenance for rural homes, and arena leveling for equestrian use. The attachment also works well for preparing building pads, leveling construction sites, and maintaining forestry access roads.
Efficiency and Safety Contributions
Seventy-two inch working width covers ground quickly, reducing passes by 30 percent compared to 48 inch models. Hydraulic ripper teeth allow depth adjustment from cab without stopping, saving time on long driveways. Removable planer comb levels after ripping in one pass, eliminating separate grading operations. Fixed screen trays collect debris, preventing redistribution of rocks onto finished surfaces. Eleven hundred pound carrying capacity transports bucket or materials while grading, reducing extra trips.
Hydraulic cylinder control keeps operator inside cab during ripper adjustment, eliminating manual pin changes. Heavy-duty NM400 comb steel resists impact from rocks and hard materials. Universal mount locks securely to skid steer plate with visible engagement indicator. Screen trays contain debris, reducing projectile risk to bystanders. Wide stance provides stability during side grading on slopes up to 15 degrees.
Technical Specifications

Product operating weight: 780 pounds (354 kilograms). Maximum adjustable ripper depth: 4 inches (102 millimeters). Ripper teeth quantity: 8. Cutting edge thickness: 0.75 inches (19 millimeters). Screen sift capacity: 1.5 by 3 inches (38 by 76 millimeters). Comb material: NM400 steel with 400 Brinell hardness rating. Mount type: universal skid steer quick attach. Hydraulic requirement: standard flow (15 to 25 gallons per minute) or high flow compatible.
Performance Factors
Ripper teeth penetrate compacted gravel and clay to 4 inch depth, breaking up hardpan that water cannot penetrate. Planer comb spreads material evenly across 72 inch width, eliminating high and low spots. Screen trays capture rocks larger than 1.5 inches, leaving fine material for smooth surface. NM400 steel comb resists wear from abrasive materials, lasting 3 to 5 times longer than standard A36 steel. The 8 teeth spaced at 9 inch intervals provide optimal ripping coverage without excessive overlap.
Inspect ripper teeth for wear after each use. Replace teeth when points round below 0.5 inch length. Check hydraulic cylinder hoses for leaks or abrasion. Clean screen trays of accumulated debris after rocky jobs. Grease pivot points every 20 hours. Tighten mounting plate bolts monthly. Replace comb when cutting edge wears below 0.25 inch thickness.
Safety Best Practices
- Lower attachment to ground when parked
- Keep bystanders 50 feet away during operation
- Verify skid steer mount lock engaged visually
- Avoid ripping near underground utilities
- Use hydraulic relief valve during cylinder operation
- Wear hearing protection during extended use
Never exceed 1100 pound top load capacity. Reduce ground speed in rocky conditions. Stop operation immediately if hydraulic cylinder leaks. Keep hands clear of ripper teeth during cleaning. Lower ripper teeth before transporting on public roads. Use transport lock when traveling over 10 miles per hour.
Equipment Types and Accessories
Land planes range from 48 to 84 inches width. This 72 inch model suits mid-frame to large skid steers with 60 to 100 horsepower. Accessories include replacement ripper teeth sets in standard or carbide-tipped versions. NM400 comb replacement plate for worn cutting edges. Hydraulic hose protection sleeves for rocky terrain. Transport stand for attachment storage. Top tray extension for additional material capacity. LED light kit for night grading work.

Real-World New Zealand Case
A New Zealand sheep and beef farm near Taupo maintained 12 kilometers of gravel access roads. Washboarding caused vehicle damage and slow travel times. The farm owned a 90 horsepower skid steer used for feeding and cleaning. Management purchased a 72 inch hydraulic land plane scarifier. The operator ripped compacted road surface to 3 inch depth in one pass. The planer comb re-graded material evenly across road width. Screen trays captured large stones, leaving fine gravel surface. Potholes filled and washboarding eliminated. Road maintenance time dropped from 40 hours to 12 hours per month. The attachment also prepared 5 acres for new pasture seeding, ripping compacted soil and leveling in single passes. The farm saved 3,000 dollars annually in contractor grading costs. The NM400 comb showed minimal wear after 200 hours of use on volcanic soils known for abrasiveness.
Conclusion and Future Industry Trends
New Zealand rural properties need efficient ground maintenance equipment for roads and paddocks. Hydraulic land planes combine ripping, grading, and debris removal in one pass, reducing fuel consumption and labor hours. Future designs may include laser-guided grading for precision leveling on sports fields and building sites. Hydraulic angle adjustment could improve side slope work on cambered roads. Remote monitoring might track ripper tooth wear and alert operators to replacement needs. GPS integration could document graded areas for compliance records. Farm managers should evaluate land planes for any property with over 2 kilometers of gravel roads or regular paddock renovation needs. The combination of 72 inch width and hydraulic ripper control makes this attachment suitable for diverse New Zealand agricultural and landscaping applications, from North Island volcanic soils to South Island glacial gravels.
