The 1994 Komatsu D31P-20 is a solid workhorse in the construction industry. With a 6-way blade, this model offers versatile blade positioning for precise earthmoving tasks. Powered by a reliable Komatsu engine, it delivers the necessary muscle for tough jobs. Though showing wear with around 4,000 hours, the undercarriage remains at a serviceable 70%. Honest disclosure: the hour meter is non-functional. Hydraulic issues have been addressed with both the hydraulic pump and transmission pump replaced.

Construction equipment is essential in industries that rely on heavy machinery for earthmoving, demolition, grading, and material handling. This includes dozers, loaders, backhoes, and excavators — often the backbone of large and small job sites alike. These machines are expected to endure demanding conditions while maintaining performance across a wide variety of tasks. Whether operating in remote areas or dense urban zones, construction equipment plays a vital role in building infrastructure, roads, and facilities that support economic growth.
These machines are often used by operators who need reliability more than flash. Jobsite delays due to mechanical failure can cause ripple effects across entire teams. Buyers tend to focus on fuel efficiency, service access, and uptime history. Attachments and compatibility with other fleet tools can add considerable value over time. For contractors managing tight timelines and tighter margins, a dependable machine isn’t just preferred — it’s essential.
TKI keeps things simple and direct, helping buyers and sellers connect without unnecessary complexity.
