PROBLEM TO BE SOLVED: To provide a control device for a small-scale, hydraulic-driving, remote-controlled lumber-collecting machine for small-diameter timbers and/or thinned timbers, which enables a series of maintenance activities where a conduction driving machine having a coupling system structure is settled, thereby promptly performs work so as to be improved in workability, performance, efficiency and productivity. SOLUTION: The device for a small-scale, hydraulic-driving, remote-controlled lumber-collecting machine for small-diameter timbers and/or thinned timbers includes one-person-operational driving means for coping with transmission and reception of instruction to and from a driving device for a clutch disposed at a prescribed position and engaged/disengaged, a brake and a power generator, is prevented from operation stop due to trouble, makes an extremely-dangerous working condition secure and safe, and also saves labor by one-person central operation so as to be improved in workability in remote control, performance, efficiency, and productivity.
