6 UNFORGETTLE COMFORT ir suspension seat GRMMER seat is installed as standard equipment, which achieves excellent shock absorption and superior ride comfort. ir conditioner blowing from the rear ir is blown against the operator's waist and the back of their head, offering more comfortable operation. Lever angles allow for comfortable operations The operator can move the levers horizontally without twisting their wrist, which reduces the fatigue caused by the operations. LED door light The LED interior light automatically turns on when the door is opened or when the ignition is set to OFF. This ensures easy entry and exit at nighttime. Parallel wipers secure a wide field of view 6
