Engine
The engine is the heart of the Mudd-Ox, powering everything from the hydrostatics to electronics. Keeping up
to date on maintenance is simple and will provide longevity. Always refer to WG1605-G-E3 Service Manual for
detailed information regarding all components, service intervals and recommended fluids.
Part 1: Oil
Inspection
Located on top of the engine, behind the alternator, is the dipstick (A in Figure-1). This will be painted bright yel-
low for visibility. Pull it out of the engine, wipe it off, and then reinstall. Now pull it out of the engine and inspect
the oil level. There are holes near the bottom of the dipstick, where the upper hole “B” is the oil full level, and
lower hole “C” is the oil low level in Figure-2. Engine oil must be between these two levels to safely operate. If it is
low, locate the oil fill cap on the top rear of the engine and fill accordingly (E in Figure-4).
The oil color is also extremely important:
• Amber: Clean and healthy.
• Dark or black: The oil’s lifespan is over and must be changed.
• Mixture of brown and white: This is known as “milkshake” and could mean two outcomes. First, there may be
excessive moisture in the dipstick tube due to climate. Second, water or engine coolant has mixed with the oil,
and significant repairs are necessary. Contact your local Kubota dealer for further instructions.

Oil Change
Kubota recommends to replace oil after the first 50 hours of operation, then every 200 hours after. Oil pan ca-
pacity is 6.0 L or 1.59 gallons. SAE10W-30 will work in temperatures from -20 to 25+ degrees C.
1. Locate the engine oil drain plug (D in Figure-3). Standard location is nearest to the engine cover, towards the
bottom of the oil pan. If the Mudd-Ox is equipped with a remote drain setup, there will be a hose connected to
the drain hole. Follow the hose down and there will be a valve with a drain.
2. There are multiple ways to drain the engine oil. It is important to not remove the drain plug/open the drain valve
and let oil into the Mudd-Ox body. Mechanics may either:
A. Open up a plastic bag and place under the oil drain plug/drain valve. Then, remove the plug/open drain valve
and let the oil collect inside the bag. After oil is completely drained, reinstall the oil plug/shut the oil drain
valve.
