A lubricant tank structure for a cotton harvester wherein the tank is located at the rear of a harvester behind the engine and near the fuel and water tanks. The tank shares support with an adjacent tank and is shaped to optimize use of available space. A bladder is installed inside the tank with an opening exiting below the fluid level of the lubricant. The opening is connected to a relatively small diameter sight tube located externally of the tank. The bladder is filled to the bottom level of the gauge with a indicating liquid having a lower viscosity than the grease which is to be gauged and a specific gravity which is approximately the same as the high viscosity grease. When the lubricant tank is filled, the tank contents displaces the indicating liquid which rises in the sight tube until the height of the liquid is approximately the same as the height of the grease so pressures in the system are equalized.
