The ER® boom system is highly productive in small stem accumulating applications, where multiple boom cycles are required for each swing cycle. Ever versatile, the 845D feller buncher also has the power and stability to handle larger timber.

The durable design and construction starts with the Tigercat-built forest duty undercarriage and large diameter swing bearing. The upper assembly is built on a thick, one-piece turntable. All weldments are fabricated from high quality steel to resist impact.

The clamshell style retracting roof enclosure provides excellent access to the engine house. A swing-out door on the right side of the machine allows the operator to easily access daily engine service points. The hydraulic pumps are separated from the engine enclosure and easily accessed.

Tigercat power. Tigercat support.

The 845D track feller buncher is Tigercat FPT Tier 2 or Tier 4f powered. Tier 4f conforms to the latest emissions standards in North America and Europe. With the Tier 2 engine configuration, Tigercat brings the benefits of Tigercat power and support to harvesting professionals around the world. Learn more about Tigercat FPT

The Truth about Tier 4f
Tigercat FPT engines meet stringent Tier 4 emission levels without the need for variable geometry turbochargers, an EGR system, a higher capacity cooling system, an intake throttle body or a diesel particulate filter. The engine series offers improved reliability and lower long-term maintenance costs. Most of the new emission equipment is found in the exhaust or after-treatment system. The key is the selective catalyst reduction (SCR) which converts the harmful components of the exhaust gas stream into water, nitrogen, and carbon dioxide.
