9/17
I successfully repaired an 11.4x24 ag tire with fluid, using a stitch-it-in type patch kit (about $5 or so). Using the provided screwdriver-sized "needle" (looks like a screwdrvr with a large eye in the end), you push a piece of vulcanizing material into the hole. It seals itself thru Chas Goodyear's chemical miracle and you're done.
Unlike using same on something like my 911 with its 162 mph capability, the safety risk from such a repair is small, IMHO.
Consult a tractor dealer if necs but the kits are available from all kinds of auto and hdw stores. Get one for the kind of tire you are repairing and work with the puncture above the fluid level! If your booboo is too large and/or your tire has collapsed its bead, leaking big time fluid, well, above my pay grade.
[I did not see Bird's post until mine went up, ditto on his cautions]
