HELP weak pump or worn lift cylinder?

[Dave M7040]

I guess you had an earlier thread with more history on your tractor.

"milky hydraulic fluid

Hello everyone, new guy here. Two weeks ago I bought a Mitsubishi D2000 from my nephew. The little tractor came with
a bush hog and a small set of chopper discs. Finally got it home day before yesterday, and discovered that the 3 point was
very slow lifting the bush hog unless the engine RPM was over 1000. Checked the fluid level and could see that it was water
contaminated. The boot on the shift lever has some cracks and splits could be the point of water entry.. I'm hoping to be
able to find new ones for both the PTO and shift lever. I also noticed that the lift arms are not at the same height, seems
like the right side at least 1.5" lower than the left side. I'm hoping to be able to remove one of the arms and reposition it.
I pulled the hyd. filter and cleaned it as well as drained the fluid. I used 5 gallons of diesel to try and flush the thing I let it
drain for a couple of hours, but can't seem to get all of the watery fluid out. Is there a drain plug or some other way to
Completely drain the hydraulic system. "

Just for your future requests for help, although there is nothing wrong with starting a thread every time you need an answer, you often make it difficult to give you the best advice when, in the most recent thread you only provide the most recent details and omit the original facts in the first thread. I am not being critical but rather wanting you to be able to get the best advice possible.

More photos of the underside of your tractor please.

Lift arms have easy to use adjustments as not all implements need arms at exactly the same height. Usually, one of the links between the lift arms and the higher up arms driven by hydraulics, have a screw or multi hole adjustment which should not require you to remove anything.

This is one example:

On this Kubota, the right lift arm is screwed longer or shorter by the two handles on it, in order to adjust the side to side height of the lift arms.

Not sure why I can't insert an image. Computers are the most frustrating things sometime. I know that the button above should let do it but does it NOOOOO!
I have had the tractor for a couple of weeks so I'm not too sure how long its had problems. But I would say that the bungee cord screwed to the fender so that it can hold the hyd lever in the full up position is a dead give away.
I only gave $600 for the tractor so I'm willing to spend a few dollars to try and get it running properly.

imagine that it did insert an image for me. this shot shows the unevenness of the two top links that I was talking about.
this one is the plate on the right side of the trans housing

Sorry for the double posting, still trying to figure out how this works

found another number on the trans case

found another number under the paint on trans housing

When you were posting about milky hydraulic oil you were asking where the drain or drains were if I remember correctly.

Your photo, which I have marked up with notes, shows gear sets for each rear wheel. These gear sets are used to keep the underneath of the tractor up high and only going low close to each wheel.

These gears at each wheel need to be lubed. Right now I cannot tell if these gear sets are receiving oil from the transmission or not. They could each be separate from the transmission.

If they are part of the transmission, then this is where any water would collect as oil will float on top of water and water goes to the lowest point. It is important you clear this up quickly as these wheel gears will not tolerate being lubed by water. When you have your eyes up close to these gear sets, a drain may be more apparent than I see in your photo. I see one large plug which could be a fill plug for oil for each wheel.

Loosening a plug at the bottom of these housings on both sides after the tractor has sat overnight would have water drain out first when the plug is removed,

Did you look at the ebay manual?

From what I see in the parts manual the top plug in the pic is to show oil level, the lower is to drain. What isn't showing is a plug at the top of the axle housing that would be used to fill. I'm not totally sure but looking at the book it seems like the axle housing is separate from the trans/rear end housing. But not really sure. I think the best drain for the trans housing is the plate covering up the hyd filter. It is as close to the bottom of the case as anything I can find. Yes I did check out the manual. I am however working with the folks at Southern Global trying to get one for this tractor. I can also have my brother who lives in Mississippi pick it up for me to avoid shipping. $17 seems a little steep just for shipping.
It also seems that if I want to test pump pressure I will have to CUT the high pressure line and install some sort of tee in the line for the gauge. Not something I really wanted to do.
