A swing machine purpose-built for productivity

We developed the TN230D from the ground up with one goal — merging quality components with the latest technology. Your forestry operation will benefit from increased horsepower and faster cycle times.* Operators will appreciate the wide views, rear-entry cab design and large cooling package.

Excellent visibility — elevated cabin with large windows, overhead skylight and front-view camera
Dual service platforms — the first in this machine class segment to offer this feature
Improved service access capabilities to components* such as the engine and hydraulic main valve
*Increased power, faster cycle times and improved service access compared to the PC210LL-10 Komatsu truck loader (a similar class machine).

Features and benefits

Purpose-built forestry machine

Total ground-up design for tough forestry jobs. Features and improvements were engineered by integrating customer feedback.

Exceptional serviceability

Electrically actuated left and right-side service platforms with repositioning of the main valve to allow better access. Also allows better entry to the engine through the large electronically powered engine hood.

User-friendly operator accessibility

Swing machine is designed to drive zero harm when the operator is entering the cab. Rear entry cab includes walkways and safety railings.

Designed for reliability and durability

Built with proven, high-quality components. Hydraulic system, powertrain, control valve and interior components are designed and manufactured in-house to help ensure performance and quality control.

Excellent operator visibility

Elevated cabin with large windows and front view camera to optimize operator visibility. Large overhead skylight also allows better visibility and improves the operator experience.

Power Max

Useful when your operators need a boost of power for forestry challenges. Power Max momentarily increases the engine horsepower and hydraulic flow to help accomplish a tough task.
