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.
In an agricultural harvester having a fore-and-aft extending frame supporting an engine, tank structure for receiving and storing a fluid material such as grease having a preselected specific gravity and relatively high viscosity so that the fluid material does not flow freely through a small tube, the tank structure comprising:
In a cotton harvester having a fore-and-aft extending main frame including transversely spaced beams supported for movement over the ground by wheel structure, the wheel structure including a rear wheel assembly located near the aft end of the main frame, an engine supported on the main frame adjacent the rear wheel assembly, a first tank located at the aft end of the frame behind the engine and supported between the beams on a support section of the main frame, the first tank adapted for containing a first fluid, and grease tank structure comprising a grease container for receiving grease, wherein the grease container is supported adjacent the engine and adjacent the first tank on the support section and includes structure in direct fluid communication with the container for determining grease level in the container from a location outside of the container.
