I have an L35 that sat for 4 yrs without being used. I was advised that some of the seals may crack as a result of going that long without any motion. I just had one of the loader seals spring a leak (fixed by warranty) but am noticing that I get some leakdown, particularly in the hoe.
I am not sure if some leak down is normal or if it affects the performance of the implement. To try to put it in perspective:
When using the hoe, the stabilizers need to be re-juiced about every 15 minutes and this will raise the tractor about 6 inches.
If I pull the hoe up all the way as if to prepare for travel, the boom on the hoe will arc forward so that the boom / dipper joint will move approximatly 12 inces when I re-juice it to bring it back.
I can raise the front of the tractor 6 inches (actually can raise it more than that) and it will stay relatively in place for 3 hrs.
Does this sound like excessive leak down? If so, does it affect the performance of the implement or is it just annoying.
Are there some standard tests that I can perform that will tell me if I need to have this looked at?
Thanks

One bit of missing info: The boom / dibberstick joint travel of 12" occurs over a period of about 45 to 60 minutes. ....

That sounds similar to what I get with my hoe although I don't try to raise the rear completely off the ground with the stabilizers.
It's mostly an aggravation issue. I'm going the check the hoe relief valve pressure. If it's low that's and easy fix but the aggravation isn't enough for me to want to tear into the valve.
JD loaders is the only place where I've heard of leak-down standards and it's the standards that seem to be the primary aggravation at the moment. Guess a case could be made that the only time you hear of standards is when somebody wants to make something that doesn't work as well as it should. The easiest thing to do probably is point to the standards and say 'See nothing's wrong--it meets standards.'

I haven't see any owners manual that shows to raise the rear off the ground while using a hoe,not to say I haven't seen people who do it. The leak downs you are talking about are acceptable or within reason. The rates depends on cylinder size and load. ....
