Description

Engine Performance: Equipped with a Yanmar 4TNV98 engine featuring a 4-valve structure, high air intake, full combustion, and low energy consumption. The engine is controlled by an ECU with a 9-gear speed system, providing automatic feedback and fuel supply adjustments for stable operation and high combustion efficiency.

Hydraulic System: Incorporates hydraulic components from world-renowned brands, offering sensitive action control, stable system performance, and high reliability.
