An apparatus is disclosed that is connectable to a conventional chain saw to extend the operable reach of the chain saw. This apparatus includes a support assembly to provide support against a user's leg or body portion when cutting an elevated item. The apparatus helps to elevate and control a chain saw, while cutting or trimming objects with the chain saw. The apparatus includes operationally secure mounting means to firmly engage the handles of the chain saw, and to maintain the saw in proper operative alignment and position. The apparatus reliably and securely engages a chain saw handle without requiring modification of the original chain saw equipment. The apparatus provides a mounting assembly which does not engage or otherwise adversely contact fragile plastic parts of the chain saw, such as the engine housing. The apparatus provides an assembly for remotely operating a throttle or a trigger of the chain saw.
