ASV RC-30 adding attachment case drain

[Harley19]

Hello, just joined the site. Are there any ASV RC 30 owners here?

I want to add an attachment, flail mower, but it has a third hose for case drain. Does anyone know if there is a factory case drain kit?

Do I need it at all? Can I just put the case drain into a collection bottle?

Any help on this topic would be appreciated.

Thanks
