Does this tractor have a brake master cylinder that is not a part of the hydraulic system that needs to be manually filled with mineral oil brake fluid?

If that is true and there are no external leaks likely there's a leak in the brake piston area that's dumping mineral oil brake fluid into the rear end/hydraulic oil.

Wore out is right.

Just be sure to use the right fluid.

Pretty sure it takes mineral oil brake fluid, hopefully the neighbor didn't dump DOT3 in there.
Seen it done when the owners manual wasn't read.
