Had a boom truck from the Asplund Tree Service in my yard clearing branches from around the powerlines. The chainsaw the boom man had was hydro powered.

Yeah, that's how I got the idea to search for hydraulic chainsaws under "arborist supplies". Most of the tree trimming trucks for the utilities and their sub-contractors use hydraulic chainsaws in the bucket trucks. They already have the power supply at the bucket(the hydraulics), they have a built in tether in case they drop it(the hydraulic hoses) and there is no centrifical clutch needed like a gas chainsaw. When you let go of the trigger, the chain stops right now and it can't spin because of high idle like a gas saw. It is either on or off.

The forumula for Horsepower is Torque (lb/ft) X RPM Divided by 5252. As an example you want 50 lb/ft of torque at 2000 RPM it requires 19.04 hp. Hope this helps. You can also determine the RPM of a hydraulic motor by knowing that there are 231 cubic inches in a gallon. If you have 10 gpm per minute going into a hydraulic motor that has 3 cubic inch displacement, you will have 770 rpm.
