I'm disabled and in a wheelchair and me and my 76 year old mom service our Kubot
L5040 and
B3030 by ourselves. We would never dream of calling the dealer! Ok enough chest beating........allow yourself plenty of time. If you have to be somewheres at 4 don't start it at 3. Give yourself at least 3 hours of clear worry free time. Hast makes for mistakes.
Park your tractor on a level area so you get complete drainage and a correct reading on the dip stick when your filling it.
The drain plugs/bolts under our Kubotas have washers on them that can come free as in like regular washers on any bolt. Sometimes these washers stick to the tractor, sometimes they stick to the bolt and sometimes they come off free on the bolt. Be aware of the washers and make sure they are with the bolt and back on the bolt when you put it back in.
I don't use gloves I just give in and let the oil get on my hands and shower afterwards.
Lots of paper towels as stated.
Split it up. If your doing engine oil and filter do that one day and the transmission fluid and filter another. (actually if the engine goes well you can then decide to tackle the trans).
The bolts are metric. Get a very good fitting socket and use a ratchet, set to unscrew, to unscrew the bolt. Otherwise you might be under there trying to turn the bolt the wrong way. Never has happened to me of course.....
A assistant is a great help. When your under there if you can just stick your hand out for a towel, screw, whatever it makes it faster and easier.
Make sure your drain container holds enough so that there isn't a overflow.
Let it drain a long time. It helps if the oil is a bit warm. I like to pour some clean oil into the fill hole and let it run out. I think that helps flush out some of the old oil.
Take the used oil to your local Kubota dealer for recycle. Never pour it in a sinkhole or send it off to the dump! <<~~~~~~DO THIS!!
Put some clean oil on the filter rubber seal. I sometimes pour some oil in the filter before I screw it on. Hand tighten only! If you use a tool to tighten the filter you'll have a heck of a time getting it off later.
After its all done start the engine and run it a few minutes. Then check the oil level again and top off if needed. Don't overfill. Keep it at the level reccomened on the dip stick.
Enjoy that special feeling of starting a engine that you know now has clean fresh engine oil!.........good luck!
