Check your engine oil level. If the hydraulic pump is driven off the engine it may be leaking into the crankcase? Search for the several threads already covering this phenomenon.

I betting you'll find it in the crankcase,been there done that.

Why? It's not likely to harm the engine much if at all. It's not super uncommon for a leaky injector to end up filling a crank case with diesel to no long-term damage. And hydraulic oil lubricated better than diesel...

I've seen a crankshaft seal blown out due to overfilling. Not a big deal, a ten-dollar part, but it's a bit of a thing to get to. And it may soak the clutch with oil.

"tomorrow" was yesterday. Any update?
1/4 of a quart is a mere cup of fluid. Thats not alot in a 2-week period but that depends on how many hours you put on that machine in the 2-weeks.
If this thing was used for 50-60 hours in 2 weeks....it very well could be leaking somewhere out in the field and given the small amount of loss....you'd likely never see it.
But if that was over 4 or 5 hours of use....yea that adds up quick. And if it is indeed going into the crankcase....that is something that needs addressed.
sorry for the delay... was using it all day yesterday..rained out today. crankcase oil level was fine and did not look abnormal.. no sign whatsoever of leak underneath anywhere.. im keeping an eye on it for a bit longer before going to dealer. I am parking it with cardboard under also......and yes, it could be while im using it. I was driving alot on pavement yesterday while it was raining and never saw any sign of a sheen of oil...you know how a small drop will look like alot on wet pavement.

With hydraulic fluid it is always really hard to tell when the fluid is off unless it is a quart or more. Your tractor holds 16quarts of fluid and the dip sticks are not that accurate. If there is any small change in angle of the tractor or position of the 3pt hitch or loader the lever will be off up to a quart. The 3pt cylinder is a large bore single acting and probably takes over 2 quarts to fill when it is raised.

Come on a 1/4 of a quart in 2 weeks time?
You say you are parking on cardboard and can't find a leak.
You have monitored the engine oil and it's not increasing.
Now it's going to the dealer to look at, you can't find a leak and you think the dealer is going to????
HE's not going to send hours looking for a possible problem.
It will get a walk around and then left parked till you call for it, because if it doesn't show up he can't find it.

well if i don't bring it to their attention later on down the line if something goes bad, they will say why didn't you bring it to our attention sooner. I rather put it on them. I have owned 7 tractors of all sizes never had to add hydraulic oil unless i blew a line or something like that.

Go to the dealer and tell them about the leak and see if they will give you a bottle of dye that shows up with a UV/black light and add it to the hyd oil. If the oil is getting into the engine oil it should show up after you use the tractor for several weeks. Then take a sample of the engine oil to the dealer and have them check it for the dye.

Raising & lowering the 3pt, loader or any hydraulics causes the sump level to fluctuate a lot. If you ever hook up any new (dry) hydraulics, that eats up several quarts.
As others have said, how much & often have you had to refill your hydraulic sump?
I have a good number of dust & oil caked fittings on my new L4060 where I know tiny amounts of fluid have made it out. But not nearly enough to be noticable on the dipstick. If it was leaking externally you should be able to see it pretty easy. If not, wash the tractor, dry it, run it then look for the oily dust accumulations.

all good points...in the big picture i think im overstressing it... im kindof a neatnick I will give it a pressure wash tomorrow. also, i have put in close to a gallon in 4 weeks...that seems like alot to me... have not been switching implements etc.. no new hydraulic toys to eat up fluid.

A gallon in a week is excessive unless it was just low to start with (like they topped it up before hooking up the loader dry or something). As long as it's not ending up in the crank case it's nothing to panic over though. Just take your time & find the leak. Keep it properly topped up until then.
