Six wheel drive skidder

Tigercat builds the most advanced, efficient and refined skidders. The 615E is a fast, light weight six wheel drive skidder. It is ideal in applications where soil compaction is an overriding concern. When lower volumes or tight spaces limit the productivity of the larger 635E, the 615E skidder is the right choice.

The 615E skidder is Tigercat FPT Tier 2 or Tier 4f powered. With the Tier 2 engine option, Tigercat brings the benefits of the E-series skidders to more forest harvesting professionals in Australia and New Zealand.

Tier 4f conforms to the latest emissions standards in North America and Europe. Tigercat’s superior Tier 4 solution is packaged into a physically smaller engine compartment than competing machines, leading to clear operator sight lines.

The difference is in the drive…

Hydrostatic drive offers many advantages. Performance in tough terrain is excellent because full tractive effort is available at any engine speed, minimizing wheel spin and improving breakout performance. The operator appreciates simplified drive control with no gear shifting.

Electronic control technology combined with Tigercat’s unique hydrostatic drive system allows the  skidder to operate at variable engine rpm, automatically increasing engine speed when additional horsepower is demanded. The result is improved fuel economy.

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.
