I doubt it. I'd bet you could pick up and flip over the whole machine with any of those "arms" and not hurt the hydraulics, with or without the levers.

Like someone suggested the strainer in the trans. case should be pulled and cleaned, I found out about this on my 310b a few years ago.
Also, it sounds like your filters are leaking too, I found these to be difficult to get the thin oring to seal and mine leaked for a while.

Unfortunately that's a bad sign. The strainer packs up with chunks and gunk which makes it hard to pull out. The hard bits will usually be brake friction bits.
I remember driving a large screwdriver between the outside wall of the strainer and the transmission case to get enough space to grab the plastic strainer with some small visegrips, then rotating it while yanking on it, once you get it moving it will usually come on out. Then you have to try to clean all the junk out of the bottom of the case. Probably need a new plastic strainer, Deere dealer should have it, when I bought one last it was less than $50, YMMV.
NOT regular heater hose though, it's hydraulic return hose rated for oil at 100 psi I think.

I had issues with my backhoe and the screen was one, flushing with diesel and pulling with needle nose pliers, eventually worked. Check out the thread; https://www.heavyequipmentforums.co...d-Metal-In-Transmission-Screen&highlight=310b
I wouldn't run it much with that tsc 303, It would be ok to flush it out with I am sure. it says on the can that it fits all makes and list cat and oliver and deere but then at the bottom says in bold not for anything with wet clutches and nothing newer than 1973. sort of like a CL ad that tells you "van for sale ready to go needs nothing" . then goes on to tell you in the description that it need brakes muffler and a battery. lol

hello
thanks for heads up on hydraulic 303 fluid . i read other post and thinking about pulling top cover off --use a compressed air engine cleaner sucking up diesel in and give good cleaning then fill with 10 gallons of diesel and let set . got to get new filters at jd dealer tommorrow . what hydraulic fluid would you use ?napa premuim or tsc premuim fluid ?

I took the cover off so I could inspect and thoroughly flush/vacuum/magnet inside. If I recall correctly, others said it wouldn't be necessary.
My procedure was take both drain plugs out, screen out(eventually), side opposite the screen (there's a small tube on out side, screen rest in 'pocket' ) and maybe ten gallons of diesel.
Put a screen from sherwin williams on a 5 gallon bucket (for straining paint) under the drain plugs to capture what was flushed out, And just kept magnet/flushing/ repeatedly. Used a weed sprayer to get in hard to reach spots.
In my opinion, this worked best. After pouring in the diesel there was still shavings left in crevices. This took me by myself a long time, as I kept at it until there were no more shavings.
Changed fluid/filters and cleaned screen within about 20 hours of use (if I recall). Didn't get much out then or the next time.
The filters are difficult to get to seal with the thin gasket, I found it was best to hold the assembly in place and tighten down, keeping the spinning to a minimum.
I used some fluid from TSC that was Deere spec, for the first fill and use. I have since gone with hy-gard, it's expensive.

Okay, that first picture of the filter head, on the left side at the bottom of the kidney shaped port you can just see the stop rod for the one pressure regulator spool, you're that close I would try to pull the plug that the stop rod is part of, try to get that spool out, make sure the spring is good, replace any o-rings with the correct ones, make sure the spool moves freely. That's what sets the supercharge pressure for the hydraulic pump inlet.

You may have removed the tube shown, I saw the end of it in the second picture after getting this image, 
Also; The short hose between the screen fitting and filter base, wrinkled for me slightly but is not bad. I think this is due to the pieces on each end not lining up exactly.
