Abstract

A portable saw machine includes a supporting frame, a cutting blade provided at a lower front side of the supporting frame for cutting the object at the ground level, a power device supported by the supporting frame for driving the cutting blade to rotate, and a power cutting arrangement. The power cutting arrangement includes a blade supporting frame movably extended from the supporting frame to suspendedly and adjustably support the cutting blade in a substantially horizontal orientation; and an actuating unit adapted to manually actuated to drive the blade supporting frame to adjust an elevation of the cutting blade so that when the cutting blade is driven to rotate by the power device, the cutting blade is arranged to cut the object at the ground level along the predetermined path without requiring a user to pivotally lift up the main frame.
