Apologies for a naïve question but on a Kubota L3250 what are the two transmission oil inlet plugs for? Am I right in assuming the one on the central console beneath the driving wheel is for the gear box and the one at the back for the hydraulics? Are they entirely separate reservoirs? If so, where do they drain to (I see drain holes near the rear wheels and how do I tell if the level on the hydraulics is correct since I see no gauge or dip stick? Thanks.

Both fills on top of the transmission should go to the same place.

To check level, there should be a small plug on the side of the transmission about even with your left foot. Should be painted orange. Remove the plug, and the fill level is when the oil just starts to run out of it. So if no oil runs out, you need to add some till it runs out.

Should be one or two drain plugs underneath the transmission. The two back plugs are for the axle drains. There's a quart or so of hydraulic oil left in the low spots on the axles that doesn't drain out when pulling the plugs under the transmission.

The rear axle fills through your transmission. So you only need to add oil through which ever fill plug is easier to get too with the funnel and a five gallon pail :D

There is a round white/clear window by where your left foot sits in the side of the case.
There is 3 to 5 drain plugs, drain them all when changing fluids.

So why all the red?

It's Kubota site. As far as I'm concerned there is only one color.

If you kids don't quit arguing you can go sit in the car. :D:D
