i need a lil input from those that may have any an opinion on a theory i have as to why my hydraulics are actin up. changed all the fluids. drained out almost 9 gals of nasty tranny/hydraulic fluid. the system only calls for 5.8 gals. i pulled the tranny filter n cleaned it good as new. it was extremely nasty n plugged up. the hydraulics responded to the slightest touch of the lever. i only ran it bout half hours total time after that. when i fired it up again. i noticed it wasnt responding very well. n was hesitating a lilbit. it got worse n worse inna bout 15 minutes time i had lost all hydraulic lift. sept when id get off n let it idle, i noticed when ever it felt like it all a sudden the hydraulics would lift. however i did have a bushhog on the back lifted up max n took the hub n blade off to sharpen em. the hydraulic held the bush hog up for 2 days. didnt drop not 1 lilbit. it just dont wanna come back up. here's my theory, do u think the filter may have gotten plugged up again. im thinkin ta check that before i take the back off by the lift arms n look inside. altho i have no idea what id be looking at. if anyone has any theories or input id luv ta hear it.

You may have stirred up a lot of crud in there or, there may be air in the lines. I don't know a whole bunch about your specific tractor but- these are the things off the top of my head.

Isn't there an external spin on canister filter at your left heel (when seated on the tractor)? It should be on the housing. My 1983 1710 has a spin on filter there.
Nope, the 1" hydraulic line runs frum the pump up front by the radiator back to the right heel. where theres a plate on the lower side. loosed the bolt at the pump end of the line, then take out the 4 bolts holdin the tranny plate on. that plate is the plate the filter lives on. pull off the plate, remove the filter. clean it n reassemble.

user jcjetro may be able to help you with the hyd issue.. but i'd be inclined to pull that screen again and check it to see if it was nasty again. if it had lots of water in it ( like 4gallons.. ).. it may have a ton of emulsified crud or biologicals in it.. if the filter is nasty.. look the oil over.. if it is nasty again.. i'd flush her with a solvent and detergent addative and then drian, cleant he sump up, and then refill after cleaning the screen again.
if that system uses an unloader valve setup.. it may have stuck from crud. ( i havn't looked at the hyd valving on that type of machine.. it's too new for me.. )
