The PC350LC-8 and Its Role in Heavy Excavation
The Komatsu PC350LC-8 is a high-capacity hydraulic excavator designed for demanding earthmoving tasks, including quarrying, demolition, and large-scale infrastructure development. Introduced in the mid-2000s as part of Komatsu’s Dash-8 series, the PC350LC-8 features a Tier 3-compliant engine, advanced hydraulic controls, and improved fuel efficiency. With an operating weight of approximately 35 metric tons and a bucket capacity ranging from 1.4 to 2.1 cubic meters, it bridges the gap between mid-size and large excavators.
Komatsu, founded in 1921 in Japan, has consistently ranked among the top global manufacturers of construction equipment. The Dash-8 series marked a significant leap in operator comfort, electronic monitoring, and hydraulic precision. By 2010, the PC350LC-8 had become a staple in European and North American fleets, particularly in rental and contracting sectors.
Operator Experience and Machine Behavior
Operators consistently praise the PC350LC-8 for its smooth controls, responsive hydraulics, and balanced power-to-weight ratio. The cab is designed for long shifts, with ergonomic seating, low noise levels, and intuitive joystick layout. The machine’s ability to handle heavy loads without sacrificing maneuverability makes it ideal for deep trenching and high-volume loading.
One operator noted that transitioning from a Daewoo Solar 140LCV to the PC350LC-8 felt like stepping into a different class of machine—more power, more reach, and a commanding presence on site. The PC350LC-8’s boom and arm geometry allow for efficient digging at depth and excellent breakout force, even in compacted soils.
Quick Hitch System Criticism
Despite the machine’s strengths, the quick hitch system—specifically the Masterhitch design—has drawn criticism. Unlike more widely adopted systems such as Miller or Geith, the Masterhitch relies on two small hydraulic rams that engage through holes in the back of the bucket. This proprietary setup restricts compatibility to Masterhitch-specific buckets, limiting flexibility and increasing costs for contractors who prefer interchangeable attachments.
Operators have reported issues such as:
Recommendations for Fleet Managers
For those considering the PC350LC-8, it’s advisable to:
The Komatsu PC350LC-8 stands out as a powerful and refined excavator, well-suited for heavy-duty applications. Its hydraulic performance and operator comfort are top-tier, but the proprietary quick hitch system may pose challenges for mixed fleets or rental operations. With thoughtful planning and potential retrofitting, the machine can deliver exceptional value and productivity across a wide range of job sites. In the world of excavation, the right machine is only as good as its ability to adapt—and the PC350LC-8 offers both muscle and finesse when paired with the right support strategy.

Operators have reported issues such as:
- Buckets mounting backwards due to poor alignment
- Difficulty in securing attachments under load
- Limited availability of compatible buckets in rental fleets
- Increased downtime during changeovers
Recommendations for Fleet Managers
For those considering the PC350LC-8, it’s advisable to:
- Verify the quick hitch system and assess compatibility with existing attachments
- Consider retrofitting with a more universal coupler if flexibility is a priority
- Train operators on proper hitch engagement procedures to avoid misalignment
- Maintain a dedicated set of Masterhitch-compatible buckets if sticking with OEM configuration
