Just curious if you have any other external hose provisions perhaps for remote hydraulics comes to mind. That handle move or is it frozen?
 
If not remote hydraulics, then position control is about the last option I can come up with. From the looks of it, those handles don't move. Any info from the PO?
 
Not sure there's only one fitting the one in front had a black nob till my son took off with it not sure what that is ether trying to get it running again don't want to start it with out having a idea about them
 
Looks like no one has any great ideas. The locations appear to be where bolts went through the cover previously. Hmm. You could take off the side cover or both side covers for more light, and have a look inside. Do they move or are they frozen? If frozen, your problem is over. If they still move then I would be tempted to pull at least one side cover, on the opposite side, and see what there is to see. From all appearances so far, it looks to be owner installed at one point.

Well, I don't know, unfortunately.

When you figure it out, or at least have a better idea, post back. I'm curious and I suspect others are too.

Maybe the previous owner tried something that was a total failure. Or, maybe, just maybe, it was a brilliant success and we'll all want to copy his idea.
 
Well, I'm kinda stumped too. I doubt you can get fluid thru those particular holes... is that someone's idea of a home made 'Zang Thang' ???? since it is on the quadrant the way it is?
 
I got the front one to move with a little help the back one is frozen or won't move with out the tractor running the front one click when moved up and down like moving a switch when I get a chance to get it running just found out that I need a cylinder head for it and so far not having any luck it might end up being yard art but not till I find out what those levers do
 

Well Morik , I asked on the FoFH forum and got an answer from Denis from Ireland .

An attempt had been made to explain to me that it was a fitting with a dual purpose. On the one hand, by moving the extra lever the operator could control the rate of descent of any implement attached to the three point linkage, but perhaps, it's other use was more useful and because that lever was attached to a valve on the riser tube, the operator could close off the supply of hydraulic pressure to the ram cylinder so, in effect, locking off the lift arms in any selected position while leaving the other two hydraulic take off points at the bottom of the pump available for external hydraulic services that would still be controlled by the original quadrant, thus eliminating the necessity for a T bar or similar to lock off the lift arms.

This seems to me to be Bloody Marvellous ! Something that could be really useful .
So if you can be bothered photos of the installation both inside and out might prove to be very popular around the world :)
 
When I get a chance to open the case I will get pics trying to get it
running again first then I will I want to change the fluid in the rear
end then I can get pics
