I got my old 790 John Deere tractor stuck like that once.....with a rain storm looming. Like you, I was able to get my SUV nearby and pull the tractor free with the SUV. Phew.....it rained a couple of inches within hours of getting it out. :eek:
After that episode.....I bought the best come-along on the market as a back-up plan. Super duty, cast iron model used by the off-road crowd. ;) Have not needed it since. :) (tho I couda used it when I got my UTV stuck last fall out on County land :oops:)
