DEF fluid in heavy equipment !!

[Supermario]

I couldn't decide if I should post in general discussions or here but nobody has anything good to say about DPF's , regen and all that stuff so I think this is the right place.
i don't work on trucks, I'm all heavy equipment and have only seen the second generation or tier 4 interm systems like on this 336E excavator which is built like a module and easy to remove in one big chunk. Heck, atleast you see the engine!





But the other day a brand new 140M grader rolled in the yard. (Going out for sales demo).






I figured I'd take a peak. My heart skipped and I thought , oh no when I saw this.....



Then I made the mistake of opening the engine compartment doors I think there's a motor in there somewhere





So now you know why I posted this here. am I ever glad I'm at the tail end of my career on the shop floor. I pity the new up and coming young guys.
