Hello; Back in the day if a piece of equipment got too stuck and it was going to cost more to retrieve it than lose it, it would be left to sink into the ground and/or corrode away. Not any more; you cannot abandon a piece of equipment these days due to strict regulations. That's not to say it ain't being done. To this day I know a housing complex sitting on top of a bulldozer got stuck in the muck trying to clear that property. Would not be hard to let it set a few days, weeks, months, and it settles on down enough to be buried over. Yah, the fastest way of cutting down the trees and making lands treeless and lifeless. Best dangerous driving of heavy equipments take care always all godbless and more power to ur families and friends.
