I want to get a log splitter but am confused by the Kubota Power Beyond (PB) feature. The 3PT splitters I have seen so far only have two hoses. I would propose to use the Backhoe hydraulics which has the three hoses. With the BH off the PB hose couples to the Supply (P) connector and the Tank Return (T) is left capped. Logic from tracing the hydraulic circuits in the shop manual tells me that it should work using the P connection and either the R or T connection as eventually the PB piping goes to the tank but maybe the PB is the better one. Also I would pre-fill the top of the cylinder (they hold a lot) in the upright posistion to keep from running the tank too low when first putting in operation. After that any fluid would either be in one end of the cylinder or the other. I would put a vent connection on the top of the upright cylinder to bleed air instead of circulating all of it.
Am I on the right track? My dealer says don't do it as he has never seen a successful hook up for a 3PT log splitter and will no longer sell them as he has had to take too many back. With the 6.3 gpm pump capacity I would expect slow cycling but I am not planning to make a living with it just save my poor old back. That is why I would use one in the vertical posistion. The big limiting factor is the hydraulic pressure limited by the relief valve to 1778-1849 psi which I assume is factory set at the lower value. But this is also a function of the cylinder Diameter but the larger the cylinder the slower the cycling.
I get the idea fast that my dealership is a little short in the hydraulic theory arena. They seem to want to stay with only Kubota recommendations. Strange as they also sell construction equipment. Also I cannot get power curves for either the PTO or the Hydraulics. I do not like to run my engine full open if the load does not require it. I usually stay around 2100 RPM and can do most things I need to do. I tend to baby my equipment as experience indicates that it lasts longer. At the max throttle of 3200 RPM the engine is screaming.
Am I thinkig straight. I need some experienced advice, Ron
