Caterpillar Inc. is pleased to debut the Cat FM528 GF/LL (General Forestry/Log Loader), a forestry excavator designed for adaptability and efficiency.

This machine is crafted to meet the diverse demands of forestry professionals, providing them with unparalleled versatility, enhanced operator comfort, and cost-effective performance.

The Cat FM528 represents our commitment to understanding and responding to the evolving needs of the forestry industry. We are merging adaptability, operator-oriented design, and cost efficiency, empowering forestry professionals to maximize their productivity while prioritizing safety.

Whether it’s land clearing, fire clean-up, chipping, grinder loading, mulching, or processing, the Cat FM528 is equipped to tackle a variety of tasks with ease. The machine is compatible with a wide range of robust Cat forestry grapples, available in sizes from 1322 mm (52") to 1524 mm (60").

The machine is equipped with Triple Grouser track shoes that help provide high maneuverability while minimizing disturbance in soft, wet underfoot conditions. To help keep operators safe, the machine is equipped with a certified side-entry Forestry ROPS cab, which includes a spacious door and an easy-to-use tilt-up armrest. Refined visibility is integrated into the design with a large 1.25-in (32-mm) thick polycarbonate windshield, narrow cab pillars, large panoramic windows, and a flat engine hood, helping operators maximize engagement with their work environment.

Versatility At The Core
The Cat FM528 offers a unique fixed or live heel and blade configuration, allowing operators to easily adapt to various applications like navigating steep terrain, managing heavy logs, or performing detailed sorting tasks.
With options for processor, roadbuilder, log loader, and knuckleboom loader controls, this multi-configurable machine helps crews easily transition between forestry and millyard work, increasing productivity and profitability.

Efficiency Meets Performance
Powered by the Cat C4.4 173 hp (129 kW) engine and an advanced electrohydraulic system, the FM528 is designed to help lower fuel consumption while delivering superior performance. The high-torque engine operates effectively at low RPMs, minimizing maintenance costs from wear and tear while maintaining precision in various job tasks. Further, the hydraulic system features cooling E-Fans with reversing capabilities to optimize engine efficiency and temperature control.

Sharing common parts and service with the Cat Next Generation excavator line, the FM528 ensures readily available components, significantly reducing downtime. Using Cat long-life fuel and hydraulic oil filters with extended and synchronized service intervals also helps lower maintenance expenses.
