以高知大学森林为例，分析了使用新型采伐机械进行皆伐的生产率。每年砍伐一小块土地（平均0.15公顷），为森林科学课程的学生准备一个实践种植场地。直到2015年，收获作业都是由小型系统进行的，例如安装在绞盘上的小型集材机。然而，在2016年，一个更新的系统被引入，在0.25 m3铲斗大小级别的基础机器上配备了一个处理器头和一个具有3吨装载能力的集材机。2016年11月，使用这一新系统进行了一系列操作，包括切割、伐木、加工、造材和转运。总生产率超过4 m3/人-天，比以前的系统（2 m3/人-天）有显著提高。生产力的一个关键因素是提取的处理器，这是受角度的砍伐树木相对于带状道路。
A case study was analyzed on productivity of clear cutting conducted by novel logging machines in the Kochi University Forest. A small block (0.15 ha in average) has been clear-cut annually to prepare a practice planting site for the Forest Science Course students. Until 2015, harvesting operations were performed by a small-scale system, such as a winch-mounted mini-forwarder. However, in 2016 an updated system was introduced with a processor head equipped on a base machine of 0.25 m3bucket size-class and a forwarder with a 3 t loading capacity. A series of operations was conducted with this new system in November 2016, including cutting, logging, processing, bucking, and forwarding. The total productivity was evaluated at over 4 m3/person-day, a significant increase over the former system, at 2 m3/person-day. A critical factor in productivity was extraction by the processor, which was affected by the angle of felled trees relative to a strip road.
