Do you have a loader and loaded tires on that massey 52HP?? IF not, the truck will out weigh it by almost double.
The tractor does have better traction, but the added weight of the truck, unless you are in mud, it would be close.
IMO, if one can do it, the other can. If one cant, the other likely cannot. It is a toss up.
That said, I would opt for the truck. The added speed with the push of the pedal to keep the towline tight through out the fall is what I would want. I have seen trees start to go in the direction intended, and then either twist, or hang up on something and go off course. The tractor wont be fast enough to keep the line tight.
