Once he stuck the tractor, he should have concentrated on getting it out, not both.
Use logs like this is quite common in the woods, but he cant have pulled right, if he attached the cabel below the center of the rear axle he would have pulled the front doen.
The logs change everything. Even below center of gravity, those logs act as a lever around which the tractor rotates against. Even without a chain, if he could 'fix' the wheels in place, that tractor should have the power to spin itself around in a circle.
Suppose the operator is in a hurry to get the job done, and decides to hitch the chain to a higher point on the tractor for extra traction, as was demonstrated. The chain attached high on the tractor with the other end fastened around the still-immovable stump prevented the rear wheels from moving forward. This resulted in what is called ‘rear axle torque,’ during which rotational forces move the tractor backward around the rear axle, lifting the front wheels off the ground. The high angle of pull, with the chain attached well above the safety of the draw bar, left no counteracting force, and a rollback resulted. (The same ‘rear axle torque’ with a potential backflip can occur if the rear wheels are unable to move because they are stuck in the mud, or if the operator tries to accelerate rapidly while pulling a very heavy load).
