Well I'm from Buffalo originally, and Rochester isn't far from there. This is Upstate NY, not N.Y. City, so there are some brains still around. Find a tree or a fence post or pound a steel stake into the ground. Run a steel cable or chain between the stake/post/tree and the machine. Run another cable from the center of the 1st one to your car. The stuck tractors will walk right out. The second cable has a huge mechanical force advantage, so as long as the Upstate brain gets the post into the ground sufficiently, the N.Y. City dead brain cells won't interfere with anything or or have anything to whine about. A new Upstate NY tractor is a fair trade balance for a horse arena. Get rid of the N.Y. City tractor(s) or bury them where they are.
