Dozers are some of the most powerful earthmoving machines available on the market, and their popularity isn’t fading anytime soon. In fact, the global dozer market is expected to reach $6.5 billion by 2027, according to Market Research.
As workhorses in the construction industry, all dozers are known for their powerful earthmoving and grading capabilities.
But some brands, including the new Doosan DD100 dozer, outperform others in certain areas. The DD100 is at the top of its class in terms of horsepower and operating weight. This was intentional; Doosan planned to make a machine in the under-140-horsepower size class with an operating weight of 23,800 pounds that would offer more power to the ground and superior tractive effort compared to its competitors.
So, how does Doosan stack up against its competitors: Komatsu D39PX-24, John Deere 650K, Caterpillar D3 and CASE 850M? Read on to learn how Doosan delivers more horsepower, higher operating weight, larger blade capacity and optimal visibility.
Competitor spec information was sourced from literature located on each manufacturer’s website. The Doosan DD100 specs discussed in this article are for the US-20 LPG (low ground pressure) model.
The term horsepower is a measure of how fast an engine can deliver torque. Put another way, it’s the rate at which an engine can get work done. Torque is a factor in determining horsepower, so as the engine’s torque increases, so will its power. However, horsepower is also determined by the speed the engine is spinning, which is listed as rpm.
Horsepower best describes how fast an engine can apply force to a load. It increases as the engine’s torque increases, or as the speed of the engine in rpms increases. While torque is about acceleration, horsepower is about top engine speed.
At 122 hp, the Doosan DD100 dozer leads the way with more power to the ground and superior tractive effort compared to its competitors.
Outstanding Operating Weight
Operating weight isn’t to be confused with equipment weight. In fact, it’s another way to describe the counterweight.
As you can see, the new DD100 dozer is at the top of its class for operating
weight at 23,800 pounds, making it ideal for residential and light commercial construction. Its main task is fine grading.
Larger Blade Capacity
The heavy metal plate of a dozer blade does all the lifting and moving. The Doosan dozer’s 3.4 cubic yard blade capacity provides precision when moving or grading dirt, clay and other materials from nearly any angle to reduce the number of passes on each job. The dozer blade moves freely to lift, tilt and angle.
One of the biggest differences between the DD100 dozer and other brands is the visibility to the machine’s blade. As you can see, the front engine compartment of the Doosan DD100 dozer offers a narrower design compared to the CAT D4 — making it easier for operators to see their work.
Customer Ray Trainor, co-owner of Ratoskey & Trainor, an excavation and recycling company based in Pennsylvania, can attest to the dozer’s visibility. He and Rob Ratoskey received the first Doosan dozer and immediately put it to work spreading topsoil and milling.
“Visibility is the name of the game,” Ray says. “In smaller machines, when you’re doing roadways and putting stone on grade, you’ve got to see what you’re doing, and the visibility in the Doosan dozer is good.”
