Cab
TCi cabs provide an exceptionally robust, quiet, and comfortable working environment designed to reduce operator fatigue throughout the day.
The parallel-action air-suspension seat is wide and ergonomic. Its fully adjustable backrest reclines and features angle adjustment, seat extension, and lumbar support, allowing every operator to achieve an optimal driving position.
Integrated heating and ventilation ensure excellent comfort, regardless of weather conditions. Ample, strategically placed storage compartments keep personal belongings and documents within easy reach while maintaining an organized workspace.

Engine


The TCi 820 is powered by a Stage V-compliant, 6.7-liter, 6-cylinder FPT N67 engine.
To preserve the longevity of the powertrain, the machine features a timed engine shutdown function. Following heavy use, this function keeps the engine running long enough for the turbocharger to cool down before full shutdown, thereby reducing thermal stress and significantly extending the turbo's service life.
Levelling Corrector
The TCi 820 feller-buncher is available with a leveling system; in this configuration, it is designated the L820. This enables operation in very rugged terrain. The system utilizes two massive hydraulic cylinders and thick steel sections to provide a solution that is both simple and robust. The TCi H820 can be equipped with an optional blade.

Crane
Hydraulic connections, lines, and hoses are protected along the entire length of the TCi F27ER crane, which has an 8.2-meter reach. As with all TCi feller-bunchers, the cranes feature the ER (Energy Recovery) system, allowing the operator to extend and retract the crane horizontally—smoothly and quickly—using a single joystick. The ER system helps reduce fuel consumption and operator fatigue, thereby increasing productivity.

Transmission

With its narrow undercarriage and D6 track assembly, the TCi L820 (self-leveling version) has a width of 2,850 mm and 2,950 mm with 610 mm and 710 mm track shoes, respectively.
