Main features

Powerful Engine: The 2021 Cat 350’s proven C9.3B engine maintains strong horsepower and torque output, delivering efficient performance for heavy-duty applications like mining and large-scale earthmoving. While pre-owned, this model retains excellent compression and injector performance, ensuring reliable operation with reduced fuel consumption and Tier 4 Final emissions compliance.

Precision Hydraulic System: The excavator’s high-capacity hydraulic system remains responsive, offering fine control for demanding tasks such as deep trenching or precise grading. Though seals and hoses should be inspected due to age, the pumps and valves typically show minimal wear, maintaining smooth operation under heavy loads.

Comfortable Operator Cabin: The well-preserved cab features a low-noise design, adjustable air suspension seat, and an intuitive 10-inch touchscreen display with minimal signs of wear. Wide windows and LED lighting ensure excellent visibility, while the advanced climate control system keeps operators comfortable in extreme conditions.

Durable Build: Built with reinforced steel structures and a heavy-duty undercarriage, this used 350 withstands rugged job site conditions. Key stress points—such as the boom, arm, and swing bearing—show only light service wear, but a detailed inspection is advisable to confirm long-term reliability.

Versatile Attachment Options: Fully compatible with Cat’s Work Tool attachments, including demolition shears, tilt couplers, and heavy-duty buckets, this machine adapts to diverse tasks like material handling, forestry work, and road construction. Quick coupler functionality remains intact for efficient attachment changes.

Smart Technology: Though not the latest model, its integrated Cat Product Link™ telematics provides essential fleet management data, including location tracking, fuel usage, and maintenance alerts—helping optimize uptime and resale value for this well-maintained late-model excavator.

Application areas

Construction Projects: The 2021 Cat 350 remains a top performer for major construction tasks, offering exceptional digging depth and breakout force for foundation work, bulk material handling, and large-scale site development. Despite being pre-owned, its well-maintained hydraulic system and reinforced boom structure deliver productivity levels comparable to newer machines, making it a cost-effective choice for commercial and industrial contractors.

Municipal Engineering: Designed for precision in urban environments, this model's smooth hydraulics and low-emission engine make it ideal for utility trenching, road maintenance, and park development. Its rubber-track configuration (where equipped) minimizes surface damage, while the quiet operation meets noise restrictions—key advantages for city infrastructure projects.

Mining Operations: With its rugged build and high-capacity bucket options, the 2021 Cat 350 effectively handles quarry loading, overburden removal, and aggregate production. The heavy-duty cooling system and enhanced filtration protect critical components in dusty conditions, though potential buyers should verify wear on track groups and slew bearings given demanding mining applications.
