2023 Komatsu Excavators PC490LC-11 SLF
When you are looking for a large working range paired with power and stability, add a super long front arrangement on the PC490LC-11 for extended reach and deep digging of wet or damp materials.
Features May Include:Versatile arrangements
- Large selection of ditch-cleaning and general-purpose buckets to meet your job site’s needs. Arm tucks under boom for lowest possible transport height without disassembly.
Durability with reinforced parts
- Hardened steel and nickel plated for corrosion and wear resistance. Cast bucket power link and sealed hardened bushing provide even more durability.
Smooth loading and control
- Smooth bucket control and two return hoses to improve hydraulic performance. During the arm out function, a portion of the oil is returned directly back to the tank for smooth operation.
