Redesigned Layout

Redesigned cab layout emphasizes simplicity and easy usage. Right-hand wall and console provide easy access to all switches, dials and controls.

Travel Controls

A large rubber-covered footrest at the side of the travel pedals allows the foot to easily grip the pedal. The travel lever stroke on the 325C FM have been enhanced to improve fine controllability, making the machine easier to operate.

Automatic Boom and Swing Priority Function

For simpler operation, work mode and power mode switches have been eliminated. Instead, the automatic boom and swing priority function selects the best mode, based on joystick movement.

Monitor

New, compact monitor enhances viewing while displaying a variety of easy to read and understand language-based information.

Implement Controls

Two joystick hand levers and buttons actuate boom, stick, heel, grapple, and swing (SAE pattern). (Road builder with bucket operates same as excavator.)

Stick/Swing Controls (Left Joystick)

• Move forward and backward to move stick out and in.
• Move left and right to control direction of swing.
• Button on rear lower controls horn.
• Rear top inner button rotates grapple clockwise.
• Front button opens grapple.

Boom/Heel Controls (Right Joystick)

• Move forward and backward to lower and raise boom.
• Move right and left to move the heel boom up and down.
• Button on rear lower is one touch low idle.
• Rear top inner button rotates grapple counter clockwise.
• Front button closes grapple.

Other Features

• Oblique movement of either lever operates two functions simultaneously.
• Manually applied lever on left console cuts off pilot pressure for joysticks and travel control.

Seat

A new seat with a two-tone color offers two types of cushions, soft and firm, for operator comfort. The reclining knob is located at the right-side of the seat for easier reclining adjustment.

Cab Exterior

Newly designed using asymmetrical steel tubing for improved resistance to fatigue and vibration.

Rugged main frame design maximizes durability

• Outer frame utilizes curved side rails, which are die-formed for excellent uniformity and strength.
• Box-section channels improve upper frame rigidity under the cab.
• Inverted U-channels span the width of the main frame and are formed, rather than fabricated, for superior strength and reduced weight.
• Boom tower and main rails are constructed of solid, high-tensile strength, steel plates.
• Boom foot and engine mount areas are reinforced for additional strength.
• Sheet metal supporting structure is improved by integrating the mounting into the upper frame structure.

Carbody Design

Advanced, reinforced, purpose-built carbody design stands up in the toughest forest applications.

Carbody Structure

Wide, tall, and thick carbody structure provides operating stability and durability while improving operation's effectiveness.
• Upper structure weight and stresses are distributed evenly across the full length of the track roller frame.
• Smooth transitions and long welds help reduce stresses at the carbody-to-roller frame junctions for excellent durability.
• Robot welding helps ensure consistent, high-quality welds throughout the manufacturing process.

Shoe Support Guards

Standard full-length track shoe support guards help protect rollers and provide increased rigidity to track links in rough underfoot conditions.

Factory Forestry Cab

Caterpillar factory forestry designed and built FOPS cab has options for windshield guard and window guards to meet local guarding requirements. The right side and rear windows are made from impact-resistant polycarbonate. Local regulations may require different cab protection options. Contact your Caterpillar dealer for availability.

Heavy-Duty Access Doors

Heavy-duty access doors are standard on the 325C FM and are made from 6 mm (.24 in), high-strength, low alloy steel. Positive locking latch stays closed in forestry applications. Hinges have larger diameter pins over standard doors. The smooth door profile enhances machine appearance.

Heavy Duty Top Rollers
