Advertised speeds of processors is like buying diet pills. You can lose weight by taking this little pill, as long as you do 3 hrs of exercise every morning, and dont eat donuts for breakfast. I believe that processor manufacturers publish rates of 4 cords per hr based on a number of things. Every stick of wood has to be the maximum dia and lenght and easy split in order to get those numbers. I did a little math on my proposed processor build considering those maximums. Using 2-4.5 in cylinder and 60gpm @3000psi of oil, and splitting max dia and lenght of 27in x 30 in wood, my splitter should be able to split a cord every 112 sec. or 32 cords per hr. The hydraulic saw would need to be able to cut those rounds every 7 sec in order to even come close. And somewhere i would need to find time to load the processor, advance the log, and theres bound to be other things to slow me down. Now thats humping it I dont care who you are. Knowing that every stick of wood I cut isnt going to be 27in dia or 30 in long, I know I wont be processing 32 cords per hr, but also know I wont get as tired pulling leavers as I would rolling rounds on a splitter, so I can work longer between breaks. Even tho I wont be getting big numbers of cords split per hr, I should still be able to get good numbers of cords per day, and not be sore and worn out doing so. Now just in case my processor does happen to produce 32 cords per hr, I will be taking bids so everybody head to the bank and get a credit check and prepare for the bidding war.
