Komatsu GD825A-2 vs Shantui SG15-G: Which Motor Grader Fits Your Project?
The Komatsu GD825A-2 and the Shantui SG15-G are not built for the same scale of project, so matching machine size to job size matters more than comparing every number. Komatsu is a long-established Japanese brand with deep roots in Indian road-building, while Shantui is a newer, fast-growing Chinese brand known for offering more standard features at a lower cost of ownership.
A bigger engine and longer blade generally mean higher fuel use per hour, so weigh that running cost against how much roadwork you actually have. If your project involves government road tenders, check the exact blade length and engine power the tender specifies before shortlisting either grader. See the full range of motor graders or read our motor grader buying guide to match machine size to your job.
Komatsu GD825A-2 Motor Grader
Pros:
Powerful Komatsu engine with 280 HP
Long blade length of 4878 mm
High forward and reverse speeds
Large fuel tank capacity of 500 L
Optional AC cabin available
Cons:
Higher ground turning radius of 7900 mm
GPS is not available
Potentially higher operating costs due to larger engine
Shantui SG15-G Motor Grader
Pros:
Efficient and high-torque Weichai 160 HP engine
Good maneuverability with a turning radius of 7200 mm
AC cabin and GPS come standard
Emergency braking feature in service brakes
Cons:
Smaller blade length of 3660 mm
Lower gross power than the Komatsu model
Smaller fuel tank capacity of 290 L
Pros:
Cons:
Closing Recommendation
Both these motor graders can handle road-building and site-levelling work, so the right pick depends on the size of your project. Choose the Komatsu GD825A-2 when you need more engine power and a longer blade for large road projects. Choose the Shantui SG15-G when you want GPS and AC cabin as standard, along with easier turning in tighter spaces. So match the machine to your work: Komatsu GD825A-2 for large-scale roadwork, Shantui SG15-G for standard comfort features and easier maneuvering.
Komatsu GD825A-2 Vs Shantui SG15-G Motor Grader Price, Technical Specifications & Features
The Komatsu GD825A-2 motor grader is a flagship model in India for haul road maintenance and heavy-duty applications. Built for contractors managing mining, quarry, and large infrastructure operations, this grader machine delivers exceptional performance in tough environments. It features a 298 HP engine that provides powerful output for continuous heavy-load operations. A 4.88-meter moldboard ensures maximum coverage and high-volume productivity, requiring fewer passes and faster grading in mining conditions. The hydroshift transmission supports efficient power delivery with better control under load. The CLSS hydraulic system allows for precise blade control with multi-function efficiency. The robust structure maintains stability and durability in extreme terrains. This machine from Komatsu Construction Equipment is the ultimate choice for buyers seeking ultra heavy-duty, mining-grade, high-capacity road construction equipment.
Road contracts live and die by grading, and the Shantui SG15-G motor grader covers that work at a practical size. Its Weichai engine is rated 160 HP and meets CEV Stage IV norms, pulling a 3660 mm moldboard with a maximum cutting depth of 500 mm. Gross vehicle weight is 13000 kg, and it travels at up to 42 km/hr between stretches.
That mix suits state road packages, rural road work and haul road maintenance at mines and quarries. The cab gets air conditioning and GPS as standard, so owners can track machines posted on distant sites, and the electro-hydraulic transmission takes the strain out of long grading passes.

Questions buyers ask about the Komatsu GD825A-2 vs Shantui SG15-G
Ans.
The Komatsu GD825A-2 suits large road projects better. It has a longer blade and a bigger fuel tank, so it can work longer stretches without stopping to refuel. Use it for major road-building and large earthmoving jobs.
Ans.
The Shantui SG15-G is easier to maneuver. Its turning radius is smaller than the Komatsu's, which helps on narrower roads or sites with less room to move around.
Ans.
GPS helps the driver keep the blade at the correct level and slope without checking manually every few metres. This can save time and reduce rework on grading jobs. The Shantui SG15-G comes with GPS as standard, while it is not available on the Komatsu GD825A-2.
Ans.
The Shantui SG15-G likely costs less to run, since its smaller engine burns less fuel per hour. The Komatsu GD825A-2 uses more fuel but suits heavier, larger-scale work where the extra power pays off.
Ans.
Both can be used, but tender documents often set a minimum blade length or engine power. Check the exact tender requirements before shortlisting either the Komatsu GD825A-2 or the Shantui SG15-G for a bid.
