Introduction

Purchasing a used motor grader in Australia is a cost-effective solution for many contractors, councils, and mining operators looking to maximise their budget without compromising on performance. However, buying used equipment requires careful inspection and informed decision-making to avoid costly repairs and downtime.

This guide provides an in-depth overview tailored to Australian buyers, covering everything from price expectations and types of used graders available to operational advice, maintenance considerations, financing options, warranties, and compliance. With an understanding of these elements, you can confidently select a used motor grader that delivers reliability and value.

Types of used motor graders available in Australia

When buying used, the variety of motor graders available reflects the diverse needs across industries. Here’s a breakdown:

By horsepower and size

• Compact used graders (100–130 HP): Suitable for light grading tasks, farm roads, and small-scale civil works. These are the most affordable and easiest to manoeuvre.
• Mid-size used graders (140–180 HP): Versatile machines for regional roadworks and civil construction with a good balance of power and efficiency.
• Heavy-duty used graders (200+ HP): Preferred in mining and major infrastructure projects, offering the highest power and durability but at a higher used cost.

By control type

• Manual control models: Older used graders often feature manual joystick or lever controls, which require experienced operators but are simpler to repair.
• Semi-automated or GPS-enabled models: Increasingly common in newer used graders, these systems improve grading precision but may add maintenance complexity.

Note: Prices can vary based on region and seller, so always compare multiple quotes.

Operating a used motor grader

When operating a used motor grader, understanding operational and maintenance demands is critical to maintaining efficiency:

Key operational tips

• Licensing: Most states require a heavy vehicle licence plus Verification of Competency (VOC) for operators (Safe Work Australia).
• Fuel consumption: Used graders generally consume between 15–25 litres per hour depending on horsepower and workload.
• Operator training: Familiarise operators with the specific controls and features, especially if the grader has GPS or semi-automated systems.

Maintenance considerations

• Annual servicing costs: Expect between $8,000 to $20,000, including oil changes, blade sharpening, hydraulic system checks, and tyre replacements.
• Wear parts: Mouldboard blades, tyres, hydraulic hoses, and engine filters need regular inspection and timely replacement to prevent breakdowns.
• Service history: Always request detailed service logs and look for recent major overhauls, which can extend the machine’s lifespan.

Parts availability and support for used graders

• For less common brands, verify parts availability before purchase to avoid costly downtime.
• Key parts to confirm include mouldboard blades, hydraulic components, transmission parts, and electronic control units.
• Local dealer support or third-party workshops can help with servicing, but availability varies by region.

Financing used motor graders in Australia

Purchasing used motor graders is often more budget-friendly upfront, but financing still plays a crucial role in managing cash flow.

Financing options:

• Chattel mortgages: Secure ownership from day one with tax advantages via instant asset write-offs (subject to eligibility).
• Equipment leases: Offer lower upfront payments and flexibility but typically do not grant ownership at term-end.
• Operating leases: Suitable for short-term projects or seasonal work.

Example repayment

• A used motor grader priced at $180,000 financed over 5 years at 6.5% interest might cost roughly $3,500–$4,000 per month depending on deposit and fees.

Warranties and after-sales support on used motor graders

• Many used motor graders sold by reputable dealers include limited warranties (typically 3–12 months) covering major components.
• Extended warranties may be available at additional cost, which can be worthwhile for high-hour machines.
• Verify what parts and labour are covered and what routine maintenance responsibilities fall to you.
• After-sales support is essential; choose sellers with local service centres or strong reputations.

Compliance and certification considerations for used motor graders

Even when buying used, compliance with Australian standards is mandatory to operate legally and safely.

• AS 5327:2019: This standard covers earthmoving machinery safety requirements, including blade guards, ROPS (Rollover Protective Structures), and FOPS (Falling Object Protective Structures).
• WHS Regulations (Safe Work Australia): Ensure the grader’s condition meets workplace safety regulations, including noise limits and operator safety features.
• Pre-Delivery Inspection (PDI): Insist on a PDI report from the seller to confirm compliance with safety and environmental regulations.
• Confirm valid compliance plates and registration for mobile plants where required.

Inspection checklist for used motor graders

Before you commit to purchasing a used motor grader in Australia, a thorough inspection is essential to avoid unexpected repair costs and ensure long-term reliability. Use this professional-grade checklist to assess value and functionality:

Visual and structural check

• Check for frame cracks or welds: Cracks near pivot points or reinforcements may signal structural stress.
• Inspect blade and cutting edge wear: Excessively worn blades can cost over $2,000 to replace.
• Tyre condition: Uneven wear may indicate misalignment or suspension issues.
• Cab condition: A clean, undamaged cabin typically reflects good operator care.

Mechanical and operational check

• Engine startup: Listen for smoke, knocking, or irregular idle—signs of engine fatigue. 
• Transmission and gear shifts: Test for smooth gear changes and responsiveness.
• Hydraulics: Check for leaks and test lift, tilt, and articulation cylinders.
• Steering and articulation: Ensure full range of motion with no delay or grinding.

Digital diagnostics and maintenance history

• Scan for error codes using onboard diagnostics if available.
• Review maintenance records: Look for consistent servicing and parts replacement history.
• Confirm engine hours: Units under 8,000 hours typically hold higher residual value if properly maintained.

Compliance and registration check

• Verify compliance plates: Ensure it meets Australian Standards for site use.
• PPSR search: Confirm there’s no outstanding finance or legal encumbrances.
• Service logbook: Verify past inspections and repairs by authorised technicians.

New vs used motor graders – which is right for you?

Choosing between a new or used motor grader depends on your project needs, budget, and long-term asset strategy.

When to choose new

• Reliability: Ideal for high-output operations or remote locations where breakdowns are costly.
• Latest features: New models offer advanced fuel efficiency and GPS grading systems.
• Warranty coverage: Expect 1–3 years of full coverage, reducing your initial risk.
• Financing: Easier to secure long-term, low-rate finance for new purchases.

When to choose used

• Lower upfront cost: Used graders typically range from $90,000–$250,000 depending on hours and condition.
• Quicker ROI: Ideal for contractors with shorter project durations or limited capital.
• Minimal depreciation: After the first 3 years, graders depreciate slower, retaining value longer.

Market insight: 58% of civil contractors in Australia purchased used graders in 2023 to avoid capital overcommitment during project ramp-ups (source: Ai Group Civil Construction Outlook, 2024).

Frequently asked questions about buying used motor graders in Australia
