3-Point Hitch Log splitter dilemma

[Tomtint]

I had a BX22 with a 3 point splitter I ran off the hydro lines from the backhoe. It was ok not super fast, but way better than the ax. I now have a l3700SU and have not yet tried it on that.

Those all look like viable options. I have been looking at a power beyond loop or pinning open that valve. My only hard spot with either is the flow rate from the tractor's hydraulic pump. Kubota lists the L3400 as having 7 gpm for the flow, which I wouldn't think to be enough for a 20T logsplitter. I have been entertaining the thought of a PTO hydraulic pump, but that seems pretty cost prohibitive when compared to the cost of a free standing gas unit.....

It'll handle the 20 T fine, and like other mentioned speed will be affected, so get a dual direction splitter, like the powerhorse

I checked out those dual directional splitters, they look pretty cool. Do you get the same amount of splitting force in both directions, I guess it should be equal. I think that running QC's to the splitter off the pinned open existing valve is a good way to go. Separately, how difficult and/or expensive is it to install a power beyond loop? What other implements would require PB?

Splitting power is significantly less in the retract direction. I have the little PowerHorse 13 ton. It's split some pretty ugly stuff in the extend direction, but it has stalled on big logs in the retract direction. The solution is simple, always make the first split in the extend direction.

The difference in force is because the hydraulic force acts on an area reduced by the shaft diameter when retracting.

Agree with KennyG; the retract side will be exert less force since the rod reduces the the cylinder area on that side so there's fewer square inches of area to apply the PSI of your pump to. I split either direction with success for 90% of what I split. When I come up against a knotty log or something about 14" or more in diameter, I make sure I split from the extend side first.

Go with a 16 or 13 ton splitter. It will split just about anything the 20ton will, and the smaller cylinder size will increase your cycle time.

Those split-fires are nice
