Another 3 point wont go down L285

New to the tractor world. Just bought an L285 with a loader that runs and drives for $500 to use around my warehouses and home. Since Im not a tractor guy I have had to figure out the controls which has not been hard. Last weekend I replaced all the hyd hoses for the loader and to my surprize the hyd system has gear oil in it. OK I came here to OTT and was able to see that was OK. Now Im at the stage of getting used to my tractor and the 3 point wont go down. I have loosened the speed adjustment under the seat to the fast side and moved the lever next to the seat all the way forward and it still wont lower the 3 point.

Im about ready to take the 6 bolt cover off the speed adjustment to see if there is a stuck valve but before I do just wanted to ask questions to see if Im missing something.

Some questions I have.....is the 3 point lowering a function that requires the engine running or does it work like an engine hoist ram where after you release the pressure gravity would allow the arms to come down with weight on it?

Also wondering does fluid level cause this? It is low but the loader hydraulics work fine and im guessing that low fluid will not make the 3 point lock up.

To recap I have turned the speed adjustment counter clockwise to "F" and several positions between F and S and nothing happens when I move the lever next to the seat on the RH side up or down. The upper bars are rock solid and wont budge with me standing on them.

Any help is appreciated.

I may be slow responding today as I found a box blade about 2 hours away from me and leaving work early today to pick it up....another deal $50 from a freind's dad that had an extra one.

Thanks OTT

The feedback bar is hooked up from what I can see. I plan on buying a box blade today so I can use my forklift to get it up into position and just let the weight of it try and bring down the hitch. The tractor didnt see alot of use so being rusted is a good possibility. Thanks for your input.

Picked up my box blade and got it mounted to the 3 point. Still wont go down even jumping on it and taking it for a bouncy ride. I have tried the speed valve in different positions and move the up/down lever a bunch too. Does anyone have any tips before I start taking things apart?

Thanks Russell. Last night I got home and the owners manual I ordered off ebay came in and I can now see the breakdown of the mechanical part of the lift system and I bet the piston is rusted to the cylinder. I was able to get the arms to flex up and down about 1/8" when jumping on the boxblade so its not seized on the outside from what I can see. Looks like I need to take the unit apart and look inside for my problem. The previous owner of the tractor said he never used the 3 point hitch so I think im on the right track...just now gotta get dirty.
