Small bulldozers (typically 80–120 hp) are ideal for tighter workspaces like farms, ports, or pipe-laying projects. Their compact size and efficiency make them great for utility work, landscaping, or projects where agility is more important than brute strength.
Medium to large bulldozers (160–410 hp) are built for heavier-duty tasks such as mining, major earthworks, and infrastructure development. With stronger traction and modular design, they’re capable of handling tough materials like frozen soil or rock and can adapt to different tasks with interchangeable components.

Wetland bulldozers are equipped with longer, wider track shoes that reduce ground pressure—some models get it as low as 15 kPa. This makes them less likely to sink in soft terrain. They’re also fitted with lighter blades that minimize disturbance to loose or muddy ground. These design features allow them to work efficiently in swampy or marshland conditions where standard models would struggle.

For operations in areas where winter temperatures drop to –30°C or lower, it’s essential to add cold-weather upgrades. These can include preheaters for the engine, fuel, and hydraulic oil, as well as cab heating and cold-start kits. Switching to low-temperature hydraulic and gear oils helps maintain smooth performance even in freezing conditions.

Crawler bulldozers are the go-to choice for rough terrain. Thanks to their continuous tracks, they offer better traction and ground stability compared to wheeled models. They can climb slopes, navigate uneven ground, and work effectively in loose or rocky soil without getting stuck or losing grip.

Absolutely. Mini dozers are scaled-down versions of track or wheeled bulldozers designed for confined spaces. Despite their size, they pack enough power for residential construction, landscaping, or farm tasks. Their maneuverability and precision make them perfect for jobs that need accuracy without sacrificing performance.
