The Tigercat rear bogie axle, combined with hydrostatic drive allows the C640E clam bunk skidder to carry extremely large and heavy loads. The massive clambunk grapple elevates the load – significantly reducing drag resistance.

The C640E is an excellent choice for southern US lowland logging applications where the skidders are confined to log mats. The Turnaround® seat adds further advantage, allowing the operator to travel blade-forward or grapple-forward on the mats without sacrificing comfort or ergonomics.

The C640E can also be equipped with a dump body for other other industrial applications such as road building and other off road hauling duties.

Tigercat power. Tigercat support.

The C640E clambunk skidder is Tigercat FPT Tier 2 or Tier 4f powered. The Tier 4f engine conforms to the latest emissions standards in North America and Europe.

With the Tier 2 engine option, Tigercat brings the benefits of Tigercat power and support to harvesting professionals around the world.
