Operator Station

High visibility operator station features an industry leading unobstructed view of tree bases and tree tops, throughout full articulation. The reverse-slope windshield prevents debris from collecting.


Take a look through the operator’s eyes to see the full visibility of the working area. The front window has a reverse slope that protects the window from falling debris and keeps it clean. The front windows and the skylight are triple laminated Lexan for full operator protection. The slope of the engine house allows clear rear views on both sides.


Steering control options are available to match the customer’s needs. The standard option is wheel steering, a quarter-turn “Quick-Steer” arrangement that produces quick cycle times while minimizing operator fatigue.

Joystick Control

Joystick steering is available as an option to allow full operation of the tractor with two joysticks. The joystick system is smooth, with fast cycle times.


Cat Wheel Feller Bunchers have proven, long-life tapered rollerbearing center joints. The engine house design is very durable and angled allowing debris to fall and not collect.

Engine House

The rugged engine house is constructed of heavy plate and has locking service panels. An optional bolt-on rear canopy is available.

Roller Bearings

Large double tapered roller bearings in center for high capacity and long life.

Lift Arms

Rugged lift arms made with a large torque tube have sealed pins and lift cylinders have cast ends.


Routine maintenance is quick and simple with ground level access, central lubrication banks and a standard tilting cab. Each side of the engine house is fully accessed by removing two screen doors on each side.


Cab is tilted with easy access hand pumps.


The junction between the cab and engine house is sealed.
