Overview

Makes Log Work Productive and Profitable

The Cat® FM538 is the best choice in its size class for today’s loggers. With its high-visibility forestry cab and factory logging configurations tailored to meet your needs, the FM538 makes your work in the woods more productive and profitable.

Benefits

Built for Your Safety

Available in a choice of rear or side entry, the Certified Forestry ROPS cab is sound-suppressed, sealed, and 25% larger than the previous series’ cab with a wider and taller door.

Improves Production Up To 10%

Moves heavy logs confidently with greater swing torque. Heavy lift mode increases pressure for an additional boost for bigger timber until the task is done. More travel speed and a taller undercarriage get you up, down, and over stumps faster. 

Lowers Maintenance Costs Up To 15%

Experience increased uptime and reduced costs with longer-life fuel and hydraulic oil filters.Cat® fuel filters have double the life of the previous filters, and the hydraulic oil return filter provides 50% more service life.
