Hi,
To all Ventrac, Steiner owner, I have a question..I have a log splitter.The engine that power the splitter is 6 HP Briggs & Stratton Quantum,The engine is no longer working. I was thinking if.I would modify the hydrolic hole and make it fit onto auxilary hydraulic.Just want to know if the hydrolic pump on the tractor is powerfull enough to split the log?and what problem that I might run in to?I have a Steiner 425 with a kubota diesel 22 Hp engine.

here the spec on the Log splitter-->

25 ton maximum splitting force

• 6 HP Briggs & Stratton Quantum series industrial/commercial gas engine

• Cylinder is 4.5" diameter X 24" stroke

• Two-stage 11gpm hydraulic pump

• 18 second cycle time

• 33 quart reservoir

• Spin-on, replaceable oil filter

• 72" Vertical Height / 42" Horizontal

Alex;
Look back into the discussion regarding building a log splitter. I am sure you have enough horses the question would be the rate of pump flow and cylinder size.
I suspect that with 2 stage 12 gpm pump it should be no problem. ....

I don't see how using the auxiliary outlets would be convenient for the log splitter. Somehow you would have to run oil continuously to the splitter, but the auxiliary valve controls do not have a continuous flow position. If you just tied the valve in the open position there might be an overheating problem.

How about another approach. Power the existing pump on the splitter with the front attachment drive. You would remove the pump from the splitter and install a belt pulley on it. Then mount that on a small platform that attaches to the Quick Tach on the front. Run hydraulic hoses with quick couplers to the splitter. Then the tractor is just powering the log splitter pump as the former Briggs engine did. This keeps all of the splitter hydraulics self-contained and any high pressure "spikes" don't have the possibility of damaging the tractor hydraulics.

Jack's idea about utilizing the belt drive is a pretty interesting one.

In terms of utilizing the auxiliary tractor hydraulics, I do run my backhoe from a third control valve section in my loader valve for a rear outlet. I do have to be very clear about which hose gets pressure when the valve is pushed forward and I do bungee cord it open.

There would be more line restrictions in this oil path than operating the hoe from the power-beyond line, but I haven't encountered oil heating problems. The oil return path to the sump is through the loader valve low-pressure (TANK) line so the hookup is in effect a power-beyond application. The system pressure relief and loader valve relief valve should provide protection against pressure spikes.

I guess it's feasible that if the splitter valve is a conventional open centred valve, although overheating is a possibility. The question of how much it would split and how fast is another question. The tractor's system pressure may be less than the splitters pump and might not be enough to operate the detend. Pumps on tractors that size are usually much less than 12 gpm.
