In the video, landscape workers use a hydraulic saw mounted on the front of an excavator to prune the tops of large saplings already planted in a nursery setting. The video shows the excavator's arm steadily positioning the saw at the designated height on the tree trunk. The hydraulic system drives the saw blade at high speed, allowing workers to precisely complete the high-altitude work with only ground-level guidance and positioning, avoiding the risks associated with manual climbing. The working principle of this hydraulic saw essentially utilizes the excavator's hydraulic pump to output high-pressure oil, which drives a hydraulic motor through oil pipes, converting the pressure into a stable and continuous rotational cutting force. Compared to handheld chainsaws, it offers more power, cleaner cuts, and is more suitable for large-scale, standardized operations. The purpose of topping the trees is not to damage them, but to control their height and reduce apical dominance, promoting the growth of lateral branches and resulting in a more uniform and stable tree shape. This also reduces the risk of toppling during transplanting or later growth. This practice demonstrates the combination of modern machinery and horticultural expertise, using the controllable power of machinery to replace high-intensity manual labor, improving efficiency while allowing the trees to better adapt to the environment and landscape requirements.
