Lawn Boy z340 zero turn parts/repairs HELP!

[Lawn-Boy43]

I just bought a Lawn Boy 42" z340 hlx zero turn and I'm working on getting it fixed up. It has the Honda GXV530 engine. I've gotten it to fire up and it idles great but has some problems that need to be fixed to be usable.
The hydro's make a horrible noise when moving around. The previous owner said one side was going bad, (that's why it's been sitting for 1.5 years before he put it up for sale)
The other issue is when you try to move in any direction (PTO not engaged), the motor will bog down and act like it wants to die.

My main question is does anyone know if any of these main parts are interchangeable with other brands? Finding any info about these online is impossible, much less finding parts. I know Toro bought Lawn Boy so I'm hoping their main parts are the same? I'd like to try to fix/replace the hydros myself if possible vs taking it to a shop.
If anyone has any info at all on these, that would be greatly appreciated! Thanks

I've been poking around on their website. A lot of parts are discontinued. I guess its hard to find exactly what parts I'll need until i pull the axle and open up the transmissions. What all goes into rebuilding the hydros? Do they make rebuilt kits?

the hydros looks like Hydro Gear EZTs. Look on the transaxke to see if you can find the Hydro Gear model number.

The first tag is for the left side hydro and the second if for the right (If the pics post in order.) The pic with the stamped numbers is also on the right side. Not sure if that is helpful or not. Also please excuse the bad pic of the left side with missing #'s. I couldnt wedge my phone up in there well enough.

Hydro Gear EZT transalxes. Most parts should be available through the Hydro Gear parts distributor, just got a source that has access.

EZT Service IPL Pay attention to the decode of model specific codes above.

EZT (ZT2100, ZT2200) Service Manual

Just note these must be worked on in a very clean environment. Please clean the unit(s) as well as you can before disassembly.

For hydro parts, need model of it on it.

Thank you for the information. I cannot get the service manual link to load. I did find the "current" model numbers that lined up with the numbers I sent. Does this tell me that I have zt2100 or zt2200? If so, would a googled "zt2100 seal kit" work for mine or would it have to be more specific and instead have to match the long part number? Sorry for the stupid questions. Also, the previous owner said that the original 3/4" axles were replaced with 1" axles. I'm not sure if that changes anything
