Komatsu GD755-5R vs GD955-7: Which One to Buy?
Both these graders come from Komatsu, but they are made for different job sizes. The tables below give the numbers. Here is the simple difference. The Komatsu GD755-5R is a mid-power grader that turns easily in tight spaces, so it fits normal roads and packed sites. The Komatsu GD955-7 is a big, high-power grader with a longer blade, built for very large highway and mining work.
So the first thing to check is your job size. If your work is normal roads and you often move in tight sites, the GD755-5R is easy and enough. If your work is large and heavy every day, the GD955-7 clears more in each pass. Both are Komatsu, so parts and trained drivers are easy and it sells well later. See the full Komatsu grader range, all motor graders, or our equipment brands guide.
Komatsu GD755-5R

Potentially less maneuverable due to larger size and turning radius
Higher fuel consumption due to larger tank could increase operational costs
Pros:
Cons:
Closing Recommendation
Match the machine to your job size. Choose the GD755-5R for normal roads and packed sites, where its easy turning and lower fuel use make daily work simple and cheaper to run. Choose the GD955-7 for very large highway and mining work, where its extra power and longer blade clear more in each pass. Both are Komatsu, so parts and drivers stay easy and both sell well later. So match the machine to your work: GD755-5R for normal roads and tight sites, GD955-7 for big, heavy highway and mining jobs.

Questions buyers ask about the Komatsu GD755-5R vs Komatsu GD955-7
Ans.
Pick the GD955-7 for very large highway and mining work. It has much more power and a longer blade, so it clears more ground in each pass on big jobs. The GD755-5R is made for normal work. For heavy daily grading, the GD955-7 finishes faster.
Ans.
The GD755-5R is easier in tight or packed sites. It is smaller and turns in less space, so a driver moves it between jobs with ease. The GD955-7 is big and needs more room. For city roads and small sites, the GD755-5R handles better.
Ans.
The GD755-5R costs less to run. It has a smaller engine, so it uses less fuel on normal road work. The GD955-7 is much more powerful but uses more fuel. For lighter, steady work the GD755-5R saves money every day.
Ans.
Yes, both are safe. Both come from Komatsu, a well-known name with strong service in India. Parts come easily and buyers trust the machine when you sell later. The GD755-5R sells to more buyers; the GD955-7 sells to big highway and mining firms.
Ans.
Yes. Banks, finance companies, and Komatsu dealers give loans for both. Your monthly amount depends on your down payment and your record. Ask two or three lenders and compare first. The bigger GD955-7 costs more, so plan a larger down payment.
