Komatsu GD705-5 vs GD825A-2: Which Motor Grader Suits Your Road Work?
The Komatsu GD705-5 and the Komatsu GD825A-2 both come from Komatsu, but they suit different scales of grading work. The GD825A-2 carries more engine power and a longer blade, so it moves more material in one pass on big highway and mining road jobs. The GD705-5 comes with AC and GPS tracking fitted as standard, and it also works better in reverse, which helps on jobs that need a lot of back-and-forth grading.
For an EPC company running many sites, the GD705-5's built-in tracking makes fleet monitoring simpler without buying extra fittings. For a contractor on one large road project, the GD825A-2's bigger blade and fuel tank mean fewer stops during a long shift. Both machines share the same Komatsu dealer and parts network. Read our motor grader guide to understand blade sizes and grader classes before you choose.

Questions buyers ask about the Komatsu GD705-5 vs Komatsu GD825A-2
Ans.
The Komatsu GD705-5 comes with GPS fitted as standard. The GD825A-2 does not include GPS by default, so tracking needs a separate fitting.
Ans.
The GD825A-2 is better for big highway and mining road jobs. Its higher engine power and longer blade let it move more material in each pass.
Ans.
The GD705-5 is better for reverse grading work. It has a higher reverse speed, which helps on jobs that need a lot of back-and-forth movement.
Ans.
No, the AC cabin is optional on the GD825A-2. On the GD705-5, an AC cabin comes fitted as standard.
Ans.
The GD825A-2 carries more fuel. Its bigger fuel tank means fewer stops during a long working shift on site.
