About a month ago I posted about a silage blower moving 5000 yards sawdust 600-700 feet out in my field. So I got 300 feet of 8 inch pipe and fired up the Massy 1085 with 540 pto. Pluged up about 100 feet out. So my neighboer has a Belarus 825 with 1000 PTO (he is more interested in making this thing work than I am). We let that Russian Beast go wide open- now we are just pushing that sawdust 300 feet.Time to call in the expert. Friend of another neighbor owns a blower-fab-design company. I dont much like experts but this guy is ok - grew up on a farm. He comes out with his calculator, charts and diagrams. Immediatly he points out that the 8 inch pipe is not large enough and we need to make the blower turn faster. Good. Long story short - the furthest we can go is about 350 feet. So my other neighbor has a small blower we can put inline with a 30 HP electric motor to blow it out the next 300 feet. This is just getting too complicated - either need to run 300 feet of teck out in the field to the 30HP electric or drag a big genset out to it. Did I mention the water table is 2 inches below the surface until about June. I am ready to can the whole deal. So far this has cost me nothing but time and we farmers never bill out time. Blower man calls today- got a 40 inch sawdust blower used. If I put 60 HP electric on it - running at 2000 + RPM we can move 1000 yards per hour, 700 feet, through a 12 - 14 inch pipe. He has my attention again, but I do not have a 60 HP electric motor, not to mention starter, 300 feet of teck etc. Which finally brings me to my question about PTO HP. Assuming the tractors have about 80 - 85 HP, and we can speed up the blower speed from the PTO shaft with a triple shive, will I have power to match the 60 HP electric motor. Esentually my question is: How does tractor HP relate to electric motor HP. I am done now. Thanks, Grant
