The failure of a hydraulic system will affect the shifting quality and driving safety of a CVT tractor. In order to reveal the response of the tractor under different hydraulic system failures without destroying the transmission. the following methods are proposed in this paper: firstly. building the simulation model of CVT; secondly. https://www.bekindtopets.com/quick-find-Mustard-Printed-And-Embroiderd-Insta-Saree-Dress-top-buy/
