How do you check hydraulic fluid on Kubota 3400?

To check the hydraulic fluid on a Kubota 3400, first ensure the tractor is on a level surface and the engine is off. Locate the hydraulic fluid reservoir, which is typically marked and accessible near the rear of the tractor. Remove the cap and check the fluid level using the dipstick, if equipped, or by visually inspecting the fluid level against the markings on the reservoir. If the fluid is low, add the appropriate hydraulic fluid as specified in the owner's manual.
