Braking System: * Service: Hydrostatic dynamic braking.
Secondary/Parking: Spring-Applied, Hydraulically Released (SAHR).
Emergency: Sakai’s unique emergency brake pedal.

Key Features

Counter-Rotation: The eccentric weights inside the drums rotate in opposite directions to cancel out horizontal forces, ensuring a smoother mat finish.
Visibility: Excellent 1m x 1m visibility around the machine for increased safety.
Easy Maintenance: The engine is mounted on the front frame, separated from the operator station, which reduces vibration for the driver and simplifies access for servicing.
