Notes:
Transmission Fluid: KUBOTA Super Universal Dynamic Tractor Fluid (SUPER UDT) is the original and recommended transmission hydraulic fluid. The fluid used to lubricate the transmission is also used as the operating hydraulic fluid. To ensure proper operation of the hydraulic system and complete lubrication of the transmission, we recommend the use of KUBOTA UDT or SUPER UDT fluid for optimum protection and performance.
