I am using an old homemade hydraulic, pto driven splitter. I have the pto attached to an Alice WD-45. I hooked it up today and at low rpm's It started stopping the pto, I could see the pto shaft stop turning where it attaches to the pump. This was when I applied a load by attempting to split the first log. When I moved the splitter ram without a log it did not do this. It was stopping it just for a second or less at a time, very jerky like, intermittent. I shut it down.

I know nothing about hydraulic motors. Where do I need to start? Thanks in advance for any input!

First step - check fluid level.
 
The PTO shaft coming out of the tractor was stopping completely? That would mean it is stalling out the tractor, no? If possible take a picture of the setup you're running and I'll be glad to help.
 
It looks like the reservoir is around 2/3 full of oil. I had added some.
 
Hopefully these r usable

It really looked like the shaft where it went into the pump stopped turning. I had the tractor rpm's pretty low, but didn't notice it grunting really bad or stalling. The shaft only appeared to stop for a split second. I will say that the fact that the shaft seemed to be stopping spooked me a little so I don't really remember what the tractor was doing.

I had used this tractor lightly over a pto drive belly mower two summers ago and didn't have any problems.
 
Your WD45 has a 254mm dry disc clutch to operate the pto, if the pto stops and the engine does not, then the pto clutch in the tractor is slipping and needs to be repaired. They stopped building that tractor in 1957 and it cost around $2,400 then, so it doesn't owe anyone.

Sounds like he's more familiar with your tractor than me.
 
Assuming that the PTO is engaged (they will often freewheel when not engaged, but with no "power" behind them) The tractor in neutral with the clutch let out...if the PTO stops and the tractor doesn't - you have a tractor problem. Likely the PTO clutch as stated above.

First step is to make sure that you have the PTO actually engaged and the clutch is NOT depressed in any way.
 
Shear pin broken ?
 
No shear pin broken. The PTO was definitely engaged. Does really appear to be a tractor problem.

The WD is my wife's family heirloom, it was her Grandpa's originally. I agree it definitely owes no one anything.

Thanks everyone, I really appreciate all the knowledge here!
