All the joking aside, we have indeed had two separate failures on the 2001 773 that effectively "drained" much of the older hydraulic oil. It's great fun changing a main drive hose out in the field. (Willie59 always works in an climate-controlled shop.

While you are servicing your machine, I suggest that you inspect all of the hoses under the cab for signs of damage/abrasion from rubbing. The hoses "surge" with the changing directions and pressures. I find that some of the main hoses are maybe 1-2" shorter than I would make them, with the machines often coming from the factory with the main drive hoses lying against sharp corners of the various cases and housings in the compartment.
When I once went to buy a new hose--it was a cheap to buy the Bobcat hose as to get one made that particular day--the parts person mentioned the "hose protector" kits. Bobcat has some hard plastic pieces that zip-tie to the hoses in those places where they tend to rub. You can make your own, and maybe save the stuck-in-the-swamp-mountain-or-woods fate. And no, Bobcat had no explanation as to why they list the hose protectors for those applications in the parts fiche, but don't bother to install them at the factory. Fool me once. . . I'm sure we'll have hose failures again, but there are two hoses on my machine that are now protected from rubbing.
And no, I wasn't smart enough to do this until after the second--and avoidable--hose failure. Nothing like buying 5 gal or more of premium hydraulic fluid. . . twice. . . to teach one a lesson.
