Engine oil drain

    I have a Ferris 3100 with 37 hp Kawasaki. Due to chassis design and engine oil drain placement, they have a rubber hose with a plug in the end that is provided to implement engine oil draining. The hose makes me nervous because it seems there is risk of it failing in some way, draining the oil during operation and having the engine fail before you notice the leak. The current drain configuration strikes me as really Micky Mouse.

    Looking at the design I don't see any good way to modify the chassis to close the crankcase with hard fittings only.

    Any ideas here to make this better?

    alotof mowers have this rubber hose configuration. cuts down on the mess with changing the oil I have seen some that use hard lines. but I think the rubber hose with fitted ends/crimped fitting is better than a copper/steel tube which could shear off at the crank case causing you to have head aches as well..the rubber hose and flexible and forgiving...

    fuel line is rubber it could come off and cause damage before you are aware. your brake line sin your car are rubber and could be come damages and cause problems and when you find out its too late. all your hydro lines are rubber, and they could leak and cause damage before you have a chance to stop it...

    the rubber hose has zero pressure, its protected by the frame. Chances are you look at it at least once a day... or at the very least youd notice a puddle under the mower on the trailer when you drive it off...

    Fumoto oil drain valve

    See if you'd want to install one of those. You can still install a hose but the valve is at the pan/sump fitting. I've used one on a truck and had no leaks or any other problems with it.

    That would not work in this case, but I do like them and have one on my truck.

    It's a little work, but could you lift the engine from the deck and install a streel elbow? If there's a hole in the deck right below the drain outlet, or else plumb it wherever you need to in order to drop down to a good catch pan location. Then place the fumoto or drain plug in the " L."

    Im not sure about yours, but on my eXmark the hose is not just a rubber hose. It is a hydraulic hose, the same type hose that goes from the pumps to the wheel motors. There is very little chance of this failing or even chafing through with no pressure on it.

    Does the hose bolt just screw out of the hose (Is hose threaded?)

    I can see your concern on that, but I think what everyone is saying about it being protected and forgiving is probably right. Plus, I'm sure there's an oil level kill switch that will kill the power if the oil gets below a certain point. Not saying there isn't still the potential for damage, but that would cut down on the chance tremendously.

    I can't get the plug end loose. can I pump the oil out of the filler tube?

    I converted all of my 4 cycle equipment to use the Fumoto drain valve. I also have one on my F 250 diesel and my wife's Grand Marquis.
