Performance and availability describe the Cat® 558 Forest Machine. Purpose built, it features extreme-duty component frames that can handle the machine's powerful engine and hydraulics systems ensuring productivity, durability and lower operating costs. Options are available to fit the 538 to your specific forestry tasks.
Increased swing torque allows operator to shovel log or load / unload trucks more efficiently, increasing overall machine production.
Extended component life through new cooling package that has coarser fin spacing for improved debris flow through and serviceability.
Power and hydraulics optimized for peak productivity and delivering maximum fuel efficiency.
