Bobcat 640 FAQ

What is a Bobcat 640?

The Bobcat 640 is a skid-steer loader, a compact wheeled machine that steers by skidding — running the wheels on each side at different speeds. It belongs to Bobcat’s 600-range of loader models, an earlier generation of the company’s skid-steer line, and handles loading, backfilling, grading, and attachment work on farms and construction sites. HCI carries replacement hydraulic cylinders and parts to keep it working.
