3-Point Hitch Sorry another logsplitter question

[J_J]

You might be referring to the Prince LSR-3060, a fast extend log splitter valve.

Now I am getting the just of it. Probably go with the PB port just to do it right the first time. Was thinking of a cheaper route, but lets make life easier. Thanks for the info new what the PB port looked like but did'nt know what it was called. Started loking in my local area they are running $358 around here. Also looked at splitters Northern Tool has one that cuts both ways called the Powerhorse anyone see one of these yet?

Lots of us have the PowerHorse. The two way works well. Since I only have a 2320, I've got the small (13 ton) model. You would probably be interested in the 20 ton model. It goes on sale more often than the smaller one.

JJ I am lookin at Nothern Tools Powerhorse 20ton it says Pump 11GPM max and a max PSI at 3000, so going by your specs for the 2720 this should work for this splitter. So what flow should you go by, the total flow or the pump flow on the specs you give?

 

[greg_g]

Given that the 2720 only pushes 5 gpm, I'd say the 11 gpm/20 ton model would not be an economical choice. Even with the tractor at full throttle, the splitter itself will be cycling at under 50% of it's potential speed. At a rated 3 gpm, the 13 ton model will require far fewer RPMs out of your 2720 to operate the splitter at its full speed. I don't know many folks that split the full 26" capacity of a 20 ton model anyway. My fireplace insert for example, won't accept anything longer than 21". So most of the pieces coming off my own 26" splitter are in the 18-20" range anyway. And besides being $200 less expensive, the lighter weight 13 ton should be notably cheaper to ship.

Given the lower gal/min of the internal pump on the tractor, the PTO pump begins to make more sense. It requires no additions/modification to the tractor, is self contained and will provide sufficient pressure and flow to operate a larger splitter at an acceptable cycle time.

A PTO powered splitter requires a pump, a reservoir and the proper hoses in addition to the basic splitter. Set up requires some fabrication so if you can't do it yourself that cost has to be considered. You have to do the math on whether either type of 3pt hitch splitter beats the economics of a stand alone machine.

Thanks for the info, planning on adding a PB port for the hydrualics for the splitter ,the splitter I am looking at is not of PTO operated. I was looking at the 13 ton but on Notherns Q&A section someone asked a question if they could use there 6.3 GPM pump on the 13 ton and they said no not recommended, according to JJ's specs my 2720 has 5 GPM so my thought that won't work either. Doing more research it does sound like the 13 ton may be correct choice, due to the max preassure both is at 3000 , but 13 ton max pump is at 3gpm and 20 ton max pump is at 11gpm that is what is confussing . Don't want to have to replace seals with to much pressure. Just happen to be on the Nothern website when a popup from a rep came on chat mode he gave me a 800 number to call tommorrow for Northstar Power support then I will let you all know what I found out. Of corse they told me my tractor was to big. But still would like to here from all your responses.

You can not use total flow as that includes all pumps.

You should use the implement pump flow.

5 GPM is a good enough flow for the log splitter. I think that is plenty flow for most people, but.

There is a Prince log splitter valve called LSR3060 which is a fast extend log splitter valve. It will speed up your splitting time by about 50 %.

If you reduce the engine rpm to produce 4 GPM, the LSR3060 will make the hyd system think it is working with 25 GPM.

I am thinking that valve will give you a good workout.

Thanks for the info going to see how I can get this to fit into the system.

A note on the LSR3060 rapid extend valve. It will extend the ram about 4 times faster, but at NO LOAD. The ram will extend rapidly, but with only a fraction of the force. It is only used to take up the distance between fully retracted and contact with the log. Once the ram engages the log, you have to let off of the rapid extend detent and run the ram at normal speed to develope full splitting force. Rapid extend (as the name implies) only works on the extend stroke. The return stroke is still slow as molasses, but that's not a big deal. Since the return has a pressure sensative release, you just move the lever into the detent and move the next log into position. I usually do not have to wait long before ram has retracted far enough to make the next split. If I spend too much time jacking around with the next log, the ram has fully retracted, but rapid extend takes up the slack in short order.
