The self-powered timber slasher includes a self-propelled carrier and a powered circular saw mounted on a first end of the self-propelled carrier, wherein the powered circular saw is configured to cut timber. Further, a hydraulic motor coupled to the powered circular saw impart a rotational motion to the powered circular saw based on a flow of the hydraulic fluid that is stored with a hydraulic tank as the hydraulic motor is in fluid connection with the hydraulic tank. Yet further, the self-powered timber slasher a wireless controller electrically coupled to the powered circular saw. The wireless controller is configured to control operation of the powered circular saw based on a command received over a wireless communication channel. ## Claims ### Claim 1 A self-powered timber slasher comprising: a self-propelled carrier; the self-propelled carrier comprising a frame and an engine for generating power to the self-propelled carrier; the frame comprising a first end and a second end; a hydraulic powered saw; the hydraulic powered saw being mounted on the first end of the frame; the hydraulic powered saw being configured to cut timber; a wireless controller; the wireless controller being electrically coupled to the hydraulic powered saw; a hydraulic tank; the hydraulic tank being configured to store a hydraulic fluid; a hydraulic motor; the hydraulic motor being coupled to the hydraulic powered saw; the hydraulic motor being configured to impart a rotational motion to the hydraulic powered saw based on a flow of the hydraulic fluid; the hydraulic motor being in fluid connection with the hydraulic tank; a hydraulic pump; the hydraulic pump being configured to transport the hydraulic fluid between the hydraulic tank and the hydraulic motor; the hydraulic pump being in fluid connection with each of the hydraulic tank and the hydraulic motor; the engine being mounted on the second end of the frame; the engine being configured to generate power for the hydraulic pump and the hydraulic powered saw; the hydraulic pump being coupled to the engine; the hydraulic powered saw being rotationally coupled to the engine; the wireless controller being electrically coupled to the engine of the self-propelled carrier; and the wireless controller being configured to control operation of the engine of the self-propelled carrier and the hydraulic powered saw based on a command received over a wireless communication channel. ### Claim 2 (depends on 1) The self-powered timber slasher of claim 1 comprising a track assembly system and a wheel assembly system, the self-propelled carrier being selectively attached to the track assembly system or the wheel assembly system so as to facilitate mobility of the self-powered timber slasher. ### Claim 3 (depends on 1) The self-powered timber slasher of claim 1 comprising at least two crawler track assemblies, the at least two crawler track assemblies being attached to the self-propelled carrier, the at least two crawler track assemblies facilitating mobility of the self-powered timber slasher. ### Claim 4 (depends on 3) The self-powered timber slasher of claim 3 comprising: each of the at least two crawler track assemblies being made of a material selected from the group consisting of steel or rubber. ### Claim 5 (depends on 1) The self-powered timber slasher of claim 1 comprising at least two wheel assemblies, the at least two wheel assemblies being attached to the self-propelled carrier, the at least two wheel assemblies facilitating mobility of the self-powered timber slasher. ### Claim 6 (depends on 5) The self-powered timber slasher of claim 5 comprising: each of the at least two wheel assemblies being made of a material selected from the group consisting of steel or rubber. ### Claim 7 (depends on 1) The self-powered timber slasher of claim 1 comprising: a swing arm; the swing arm being configured to swing about a pivot; the hydraulic powered saw being mounted on the swing arm; a hydraulic actuator; the hydraulic actuator being coupled to the swing arm; the hydraulic actuator being configured to impart a pivotal motion to the swing arm based on the flow of the hydraulic fluid; the hydraulic actuator being in fluid connection with the hydraulic tank; a gear pump; the gear pump being configured to transport the hydraulic fluid between the hydraulic tank and the hydraulic actuator; and the hydraulic pump being in fluid connection with each of the hydraulic tank and the hydraulic actuator. ### Claim 8 (depends on 7) The self-powered timber slasher of claim 7 comprising a valve, the valve being configured to control the flow of the hydraulic fluid to the hydraulic actuator, the valve comprising an electric solenoid, the electric solenoid being configured to control the flow of the hydraulic fluid based on an electrical signal receivable from the wireless controller, the electric solenoid being electrically coupled to the wireless controller. ### Claim 9 (depends on 1) The self-powered timber slasher of claim 1 comprising a valve, the valve being configured to control the flow of the hydraulic fluid to the hydraulic motor, the valve comprising an electric solenoid, the electric solenoid being configured to control the flow of the hydraulic fluid based on an electrical signal receivable from the wireless controller, the electric solenoid being electrically coupled to the wireless controller. ### Claim 10 (depends on 1) The self-powered timber slasher of claim 1 comprising a ball valve, the ball valve being connected to the hydraulic tank, the ball valve being configured to shut-off the flow of the hydraulic fluid from the hydraulic tank. ### Claim 11 (depends on 1) The self-powered timber slasher of claim 1 comprising a portable operator device, the portable operator device being configured to wirelessly transmit the command to the wireless controller based on an input from an operator. ### Claim 12 (depends on 11) The self-powered timber slasher of claim 11, wherein the portable operator device is configured to be removably attached to a vehicle. ### Claim 13 (depends on 1) The self-powered timber slasher of claim 1 comprising: a camera;
