Zeal ZeTrans STOU series are extra high-performance multipurpose tractor lubricants formulated from highly refined base stocks and advanced technology additive system, to meet or exceed transmission and hydraulic fluid requirements. These oils are engineered to deliver the varied lubricant performance properties required in severe duty applications of agricultural and construction equipment drive trains. Moreover, it is particularly well suited for reducing wet brake and Power Take-Off (PTO) chatter.
