UPDATE 5/25 – The electric company spliced and re-buried the cables. It's a 120V line and should have been buried at least a foot below ground. They'll come by again to locate the rest of the line leading up to our electrical box and trench it deeper if it's too shallow. I added a photo of the progress so far.
Usually I'm pretty careful when I mow, but last time I got careless and accidentally hit this exposed cable with the mower.
I'm not sure what this is for or why it's exposed in the first place, but it's pretty close to the green electrical pillar outside our house. The outside sheathing is rubber and and the inside looks like a twisted steel cable with a bit of PVC pipe.
Any idea what this is or what I can do to bury it? Do I need to get our utilities/electric company involved?
UPDATE – Spliced and buried.

That is a Homac 600V rated splice so it's probably part of your electric service. I would be calling the power company right now and report a dig in to an exposed service or secondary lateral.
Stay away from it until the power company inspects it. It could be an abandoned line but you want to assume it's hot. It looks like a ground rod has been driven close by so maybe some old facilities have been relocated.
