A method of moving a tree, rootball and supporting platform up an inclined surface comprising the steps of supporting the platform using a plurality of inflatable airbags, progressively, from leading edge to trailing edge, inflating the airbags to elevate the supporting platform, tree and rootball and to tilt the platform, tree and rootball forward towards the incline to be surmounted, and rolling the platform, tree and rootball forward to unload a trailing airbag and to lower the platform onto the remaining airbags. This series of steps can be repeated after a replacement leading airbag is introduced beneath the leading edge of the platform and the inclined surface to move the platform, tree and rootball further up the incline.
