Seems like the factory remote kit wont have sufficient flow for a splitter, so has anyone mounted a hydraulic pump to the mid pto with a reservoir somewhere on-board?

A couple problems I see with using the mid-PTO:

-It runs at +/- 2100 RPM, it my be hard to find a pump that will run effectively at that speed.
-Coupling the pump to the PTO will be a custom fab job, and mounting it will be a PITA.
-Reduced ground clearance under the tractor, snagging the pump could result in transmission damage as well.

Rear PTO pumps are readily available, but not cheap at about $450, but they just slip right on the stub shaft and are designed to run at the standard 540 RPM.

if that tractor will support a front loader and backhoe theres no reason it would'nt support a wood splitter. i think it will, a wood splitter is one cylinder. i'd go that route.

I was thinking I'd mount on the mid because I'd like to have my tractor idling or slightly more when running the splitter as opposed to almost wide open to achieve the 540 rpms via the rear pto. The ground clearance might be an issue, perhaps a skid plate could be incorporated into the mount....

Your engine won't be in the "power band" to achieve the HP needed just idling or slightly above.

Just my :2cents:

Does the 20 have a two speed pto like the 30 does? I can select 1000rpm PTO speed and run the engine at half speed for PTO 540. Half of 2500 rpm isn't too fast.

Those PTO pumps seem huge and expensive. I wouldn't want to mount it to the belly.

I've seen these types of splitters, PTO powered hydro, and they mount the hydro tank on the splitter.

The ck20 doesn't have a 2-speed pto, the rear is 540 and the mid is 2000. I'm leaning more now towards a splitter that will work more within the ck20's ability via the factory remotes, thanks to all that responded.

You won't create any more "power" running off the mid pto. Since the power available to run the hydraulic system would be determined by the engine horsepower, you would need a smaller displacement pump off the mid pto, resulting in the same total flow to the log splitter. Horsepower is roughly equal to GPM flow at 1750 psi. Since the horsepower availabe and system pressure is constant, you would need to size the pump to keep the GPM (flow rate) in balance with the power availabe.

In other words, you wouldn't gain anything by running off the mid pto. You would just have a smaller pump, spinning faster to create the same flow.

Thanks for clearing that up. I guess i need to get some remotes for the ck20 :)
