In Korea, automatic transmissions are developed for the convenience of operating agricultural machinery. The automatic transmission conduct a role of increasing the power efficiency of agricultural machinery as well as the convenience of operation. Hydrostatic transmission is one of automatic transmissions and is often used in agricultural machinery like tractor, harvester. Accurate durability test is required to produce high quality automatic transmissions. Accelerated life tests are conducted for endurance life tests in Korea. The purpose of this study is to calculate the equivalent load in the plow tillage of a tractor with hydrostatic transmission. For this study, a pressure sensor was installed on a tractor using a hydrostatic transmission to measure load data. The equivalent load was calculated from the measured load. In the future, other agricultural will be conducted such as rotary operation and calculate the integrated equivalent load. The integrated equivalent load data can be applied to the accelerated life test.
