David, Need more info to help much. Picture would be a start.
Farmall Backhoe ? New to me and I cut my teeth on IH.
DOES NOT SEEM UNUSUAL TO OPEN HYD VALVE AND "BUNGY" IT TO FEED HYDRAULIC POWER TO BACKHOE. To avoid that some tractors have a hyd. "power beyond" port to feed an attachment.
Not familiar with LONG 2360. Does it look like a FORD and if so which Ford model ?
Stay with us and give us some more info and there are real knowledgeable guys on here that can help
