This was somewhat odd?

There is another way. At least this has worked on two Kubota's and my Kioti. Find the hydraulic vent tube. On the Kubota L series it is under the seat. Yes the little rubber shepatds crook. On the Kioti it is the fill tube rubber plug itself. Plug up the vent hole. I used a no.8 machine screw, but a golf T would work too. Now it will be very difficult for air to get into the tank so the fluid loss when you remove the filter will be slow and small. I have done the last 3 changes this way and it works well. Do NOT forget to remove the obstruction in the vent. It will blow the dipstick out onto the ground when you use your FEL. Don't ask how I know this.

Not sure on the L2501, but my kubota has TWO engine drain plugs. Does yours and did you remove both of them?

There is also a shop-vac trick for changing the hydraulic filter and not making a mess.

Take off the cap that you would use to fill the hydraulics. Put the shop vac over the hole and turn it on. The vacuum it creates allows you to change the filter and only loose a few drops.

Yes it does have two plugs to remove. Good trick on the shop vac, I'll have to remember that one. :thumbsup:

Seems like the engineers that designed these machines (and other types of machinery) would know, or talk to the people that ran them initially at the test facility, that it does not take the full amount the manuals state to refill after a change out. Surely they had performed an oil change and would note this? Or maybe pass it up the chain of command. Yeah, I know how that one goes...

I'll take a look for this under the seat, thanks.
