此文是对使用小型农用拖拉机(21HP)和小型轮式运货车(70HP)进行间伐小径木集材作业时的效率比较。其结果表明,使用农用拖拉机的成本低。农用拖拉机在林地使用虽有局限性,设计时也未考虑适应林区的作业条件,但如果使用注意的话,对小径木间伐还是合算的。运货车可进入到伐倒木地点,而且预先不选定集材道,而农用拖拉机预先要选定道路,并需用绞盘机进行小集中。生产效率的提高,取决于装载量的增

This article is a comparison of the efficiency of thin timber log skids with small farm tractors (21HP) and small wheeled trucks (70HP). The results show that the cost of using agricultural tractors is low. There are some limitations on the use of agricultural tractors in the forest land. The design of the tractors does not take into account the conditions of the forest area. However, if the tractors are used for attention, they will be cost-effective for the small-diameter wood farms. Wagons can enter the site of logging down and pre-unselect tundish roads, while farm tractors pre-select roads and require a winder for small concentrations. The improvement of production efficiency depends on the increase of loading capacity
