摘要

1998年春季，在美国阿拉巴马州东南部沿海平原上的一处采伐地，对30.5L-32 (78 cm)、67x34.00-25 (86 cm)和66x43.00-25 (109cm)尺寸轮胎在潮湿条件下的打滑效率和成本进行了评估。三种轮胎尺寸调整后的平均整树打滑产量在0.05水平上无显著差异。调整后的78厘米、86厘米和109厘米轮胎的全树轮胎产量分别为每生产机器小时(PMH) 32.7、35.8和32.9绿色吨。78厘米、86厘米和109厘米轮胎的全树总滑行成本分别为每绿色吨1.96美元、1.80美元和1.97美元。

Effect of Tire Size on Skidder Productivity Under Wet Conditions

Abstract Evaluation of skidder productivity and costs among 30.5L-32 (78-cm), 67x34.00-25 (86-cm), and 66x43.00-25 (109cm) size tires under wet conditions was conducted in a clearcut harvest during the Spring of 1998 on an Upper Coastal Plain site in southeast Alabama. There was not a significant difference in adjusted mean whole-tree skidder production among the three tire sizes at the 0.05 level. Adjusted mean whole-tree skidder production for the 78cm, 86-cm, and 109-cm tires was 32.7, 35.8, and 32.9 green tonnes per Productive Machine Hour (PMH), respectively. Total whole-tree skidding costs were $1.96, $1.80, and $1.97 per green tonne for the 78-cm, 86-cm, and 109-cm tires, respectively.
