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. The anchor rod is restrained against forward radial movement from the support structure as the ropes are tightened around a pruning stack by laying the anchor rod into the openings of J-hooks which protrude upwards from the front portions of the base plates.
