I just came up with a very simple and clean way to change gear oil on Kubota RCK54-75B mower deck. I believe it would work on the other series also.
No need to remove deck.
1. Purchase Ziploc one gallon size freezer bags.
2. Lower deck on level ground.
3. Remove belt covers.
4. Open bag and lay flat on deck then roll the sealing edge up under the gearbox untill it touches the bottom of the gearbox drain hole.
5.Drain oil.
6. Carefully lift bag sealing edge up from under gearbox seal bag and dispose of properly.
I thought this would help making mower maintenance a little easier.
