Features and benefits
More power and simplified maintenance
The D175AX-10 is powered by Komatsu's next-generation DBA127 engine. Engineered from the ground up, it delivers more power, greater fuel efficiency and lower lifetime operating costs. The EGR-less design combines high output, improved reliability and extended service intervals to help maximize productivity and reduce downtime.
More control using less fuel
A completely redesigned four-speed automatic transmission gives operators more control over machine performance across a wide range of applications. Automatic Shift Mode helps reduce fuel consumption by up to 5% compared to operation in manual mode. Operators can optimize performance for changing conditions while reducing unnecessary fuel consumption and track wear.
Steering that keeps power where it belongs
The new hydrostatic steering system is engineered to maintain blade performance while turning. An independent steering pump automatically helps balance power between steering and work equipment. The result is up to 17% higher steering force and 7% increased engine output during steering operations.
Blade performance built for production
The D175AX-10 features a newly designed 13.9-cubic-yard Semi-U blade optimized to reduce digging resistance while improving material retention. The blade profile helps you fill faster, carry more efficiently and maintain momentum. High-efficiency end bits also help penetrate material efficiently while reducing digging resistance.
Controls designed to make good operators great
Operators are empowered to doze more precisely and efficiently with intuitive controls and displays. These include ergonomic joysticks, an 8-inch monitor, a real-time pitch and roll display, preset travel speeds, adjustable blade response and more. These features also help reduce workload and support safer operation.
Exceptional visibility and jobsite awareness
The dozer combines exceptional visibility with advanced monitoring. The KomVision 360-degree camera system with a 10-inch cab display is standard. The cab has been redesigned for greater overall visibility — up to 45% greater forward views and up to 30% more rear-view visibility than the previous model.
Lower lifetime total cost of ownership
The D175AX-10 is engineered to help reduce ownership costs through improved fuel efficiency, longer component life, simplified maintenance and extended service intervals compared to the previous model. The DBA127 engine significantly helps extend service intervals for engine oil and KDPF life. Furthermore, hydraulic oil intervals and other key filter intervals have also been extended.
Smooth operator ride for long shifts
Operators experience a smooth, controlled ride with new suspension components, longer track contact, improved cab isolation and a premium operator seat. Cab vibration has been reduced by up to 35% over the previous model. That, along with a premium air-suspension seat, helps the operator stay comfortable.
Enhanced traction that stays the course
Multistage speed control settings, track shoe slip control mode and neutral auto brake feature help reduce track slip and maintain traction in difficult ground conditions. Track shoe slip control mode detects slippage during ripping and automatically reduces engine speed to help maintain traction.
Boost uptime with ultra-low-ash oil
The D175AX-10’s DBA127 engine is compatible with ultra-low-ash oil. By choosing Komatsu Care Plus II Premium with ultra-low-ash oil, you can extend engine oil service intervals to up to 1,000 hours. Ultra-low-ash oil also helps extend DPF life to up to 16,000 hours, minimizing service downtime.
Navigate tight spaces with steering modes
Operators can choose between three steering modes: pivot, power and spin turns. “Spin turn” mode rotates the machine within its own footprint for exceptional agility and maneuvering. These modes help operators keep materials moving in confined areas while making smoother corrections.
Durability for the long haul
Redesigned engine components, delayed engine shutdown, and auto power off help increase reliability. The cooling package has been redesigned to adopt a single plane cooling design, enabling efficient cooling and improved serviceability. The blade linkage has been improved to reduce wear.
