Timber crane hydraulics with John Deere

Recommended Posts

Does anyone have experience of John Deeres on timber trailers? I have just fitted a new valve block on the crane trailer as the old one had more leaks than Downing Street! The JD 6400 has closed hydraulic system and I wondered if it is possible that running the crane directly from the tractor hydraulics was the reason the last valve block failed (it was pretty well used as well). Is there something that should be done to the valve or the tractor to ensure a happy union of the two? The crane worked fine directly off the tractor but I had heard tht it may be wise to make some alterations to the ports used on the block? Any nuggets of wisdom gratefully recieved.

I had some trouble with overheating oil with a big JD running into open centre spool block. It needs the return to be to a point where it dumps directly into tank/axle with no restrictions and most definitely not returning via one of the tractor spools.

 

It may have made better use of the JD's hydraulics to have a closed centre block and load sensing valves but that's a bit too modern for my experience.
