Get yourself a Wyeth-Scott "More Power Puller" 3-ton capacity rope come-along type puller. That with 50ft of strong rope will get you out of most anything.
Those are good tools but dang they're expensive.
And heavy - big ol chunk of cast iron. But....those are what a lot of professional woods workers - foresters, lumber crews, back country surveyors - used to carry in thier trucks before electric winches were common and the only other choice was PTO driven winches.
