本工程实践旨在作为确定最小道碴和胎面设置的指南 建议操作安装在两轮驱动拖拉机或两轮驱动拖拉机上的农业前装载机 按照ASAE S390第3.1.1.1节和第3.1.1.2节的规定，驾驶带前辅助功能的拖拉机。5.这些道砟和踏面 设置建议旨在降低典型操作中车辆倾覆的风险。

This engineering practice is intended as a guide to determine the minimum ballast and tread settings recommended for operation of an agricultural front loader mounted on a two-wheel drive tractor or a two-wheel drive tractor with front assist as defined in section 3.1.1.1 and 3.1.1.2 of ASAE S390.5. These ballast and tread setting recommendations are intended to reduce the risk of vehicle overturn in typical operation.
