I would suggest you find a JD dealer and buy a manual if you want to do the maintenance yourself. You can also do a Google search and find manuals.
I would also suggest you completely drain the old hydraulic fluid and replace it with new fluid and a new filter if it has not been serviced any time in the recent past.
The symptoms you describe can be low fluid and/or a clogged filter. If you or anyone else has run the tractor too long and it has low fluids and/or a clogged filter, you can damage the hydraulic pump and that can get costly.

would say that your variable displacement pump has rust or other on/inside, it.
Are you using hydralic fluid (not eng oil) in her?
Can you let it run on blocks for a bit - drain and re-fill transmission?

You should NOT weld. braze or otherwise join, or "fix" an hydraulic lines, they, ideally, must be run as a single length again, any Join will simply fracture... Also if they are developing "Pin Holes" this is probably due to the material breaking down, and like a "Cancer" it will simply spread, and fail at a probable inappropriate time, not as though there are any good times? As an aside there are "Joiner" kit available for hydraulic lines, perhaps, cutting and rejoining like this may be acceptable? but still i wouldn't risk it, run new ones.
