The hydraulic motor is the rotary counterpart of the hydraulic cylinder as a linear actuator. Most broadly, the category of devices called hydraulic motors has sometimes included those that run on hydropower (namely, water engines and water motors) but in today's terminology the name usually refers more specifically to motors that use hydraulic ...
The log is sawn by either a hydraulically operated chainsaw harvester bar, or on larger machines, a very large circular saw blade, or a guillotine powered either directly from a pto [1] (tractor or engine powered) or by hydraulics. When the cut is completed, the "round" drops into position to be split in the next process.

Two-stroke chainsaws require about 2–5% of oil in the fuel to lubricate the engine, while the motor in electrical chain-saws is normally lubricated for life. Most modern gasoline-operated saws today require a fuel mix of 2% (1:50).
Electro-hydraulic actuators (EHAs), replace hydraulic systems with self-contained actuators operated solely by electrical power. EHAs eliminate the need for separate hydraulic pumps and tubing, because they include their own pump, [ 1 ] simplifying system architectures and improving safety and reliability.
Bush ran his saw at 404cc, about the highest that has been managed. [1] The total cost of each hot saw is about $10,000 but can last for decades, with requirements in the event rarely changing. Lemke also recommends constant maintenance of the saws, but also talks about how saw-building is just as exciting as the event itself. [1]
