Kubota stopped venting front axle?

[Orange man]

My L2501 has a vent tube off the front axle. The L2502 I am buying doesn't seem to have any axle vent. Anybody know why they have removed them? Thanks

They put them on, they take them off, they put them on, they take them off, they put them on, they take them off..........
They have done that for years, with no rhyme or reason.

It would seem like common sense to vent it. The vent is cheaper than leaking seals.

curious... the vents they are,were ? using, do they have internal one way valves to vent air out, but prevent water getting in ?

The standard L series had a vent hose that ran up into the engine compartment, I do not know on the other series.

There is quite a few models that do not have vents and do not leak.

True example: M4500DT from late 1970's, front axle not vented, no leaks.

The axle on my tractor is not vented and will build up pressure. I did have a leak, but that was at 800 hrs, so I'm not going to blame the lack of a vent on that.
However, I would think a vent would be a good thing to at least keep pressure from building up and maybe vent off any condensation.
The transmission has one, so I'm guessing it ain't a bad thing. Other type vehicles I own have front and rear differentials vents.
I'm thinking it may be a good thing and may tap a line into the fill plug to add a vent line. Has anyone done this, or any reason not to do this?
