Abstract: A device for compressing stacks of branches or twigs pruned from trees or shrubs into compact bundles includes a winch having an elongated tubular shaft terminated at one end thereof by a hand crank, and rotatably supported by a pair of longitudinally spaced apart support structures disposed transversely to the winch shaft. Each support structure has a base plate having a lower surface adapted to abut a stack of prunings, and a bearing support structure protruding upwards from the base plate for rotatably supporting the winch shaft. An aperture through the base plate disposed radially rearwards from the winch shaft receives a tensioning rope wound around the winch shaft. The opposite end of each tensioning rope encircles a pruning stack, and is attached at longitudinally spaced apart locations to an anchor rod.
