Where is the fuel drain plug on the 853 Bobcat?

Under the Bobcat, you will find an access cover about 6"X2". If you don't see the cover then there is a big chance the cover has been removed already or it has been sheared off. Removing the cover reveals two holes side by side. The hole on the left (as you are facing the rear) is the access for the hydraulic tank. The hole on the right is the access for the fuel tank. Removing the rubber grommet on the right will completely drain the fuel.
