The Cat 501 and 501HD track harvesters have been updated with the new 157 HP Caterpillar C6.6 ACERT Tier 3 engines rated at 2200 rpm. Innovative technology reduces emissions at the point of combustion to meet clean air regulations.
The Tier 3 C6.6 engine generates 11% more torque over previous Tier 2 engines in the lower rpm ranges. This additional torque provides more power at reduced rpms for increased fuel efficiency. It also maintains higher hydraulic flow under load for faster processor speeds.
The Cat track harvesters are purpose-built for cut-to-length logging. The forward mounted cab and rear engine placement provide excellent visibility over the entire harvest zone for enhanced selection capabilities. Both standard and extendable booms are available so the harvester can be equipped with either fixed or dangle processing heads.
