Edger for one time trench digger (Invisible dog fence install)?

I am wondering if the Edger with the Power+ Head would be powerful enough to dig a shallow 3 inch trench to lay a 12 gauge wire? I have a couple hundred feet to get buried and I would be ok if takes most of an afternoon because I need to charge a battery. I am looking at adding a edger/trimmer combo to start with the Power+ and get a 5amp battery as well. I do have a 7.5amp from my new mower that I can use as well.

Anyone with one done something like this?  If the edger can get the job done it is some savings from renting a trench digger that I can put towards the tool.

Thanks for any info you can provide!

Yes, it is powerful enough, but the blade may not go that deep.  Also matters if there is any gravel, rocks, tree roots, etc.  I've done things like that before, but you have to be very careful.

Good to know it is powerful enough, thanks. Any idea how long to expect a 5Ah battery to last using the edger? Manual says that it will go up to 4" deep which is just fine - I think I can get away with 3 inches down. I will stay away from tree roots and should not be much gravel/rock in my yard.

JonR, I went out and measured my edger blade and the blade is 8" long. The center hub that holds the blade to the edger is large enough that only 3" of the blade on each end is useful. So, you "might" get 3" depth, but don't count on any more than that,  if that much. Part of my edging is edging my lawn where it goes along a planter. There is nothing to separate the grass from the dirt so the edging is to keep the grass from growing into the planter. Basically digging a trench into the dirt right where the grass and dirt meet. The cut is only the width of the blade so you might have to make several passes progressing outward to get a channel wide enough for whatever wire you wish to lay in the ground. 
But, yeah, there are roots along my edging path and the edger won't touch them so you'll need to cut them a different way or snake the wire under the roots somehow.One edging pass on that part of my yard which is probably 50' or more long only takes a few minutes but I haven't really tried going the full 3" depth. Battery life hasn't been a problem but again I'm not going real deep or real far.

under constant load you will probably get 10 to 15 minutes...

My cheapest model Ryobi string trimmer/edger can cut through grass and dirt and make a trench.  Surely the EGO tools will do the same.   If you have a string trimmer, you can cut away the grass with a shovel, use the trimmer to move the dirt and expose any roots or obstructions that would damage the edger, then cut the trench with the edger.

The EGO will without a problem, but depth might be tough to achieve.  I cut deep when I edge and I estimate it to be about 2 inches.  Also the blade wears quickly so it gets shorter and shorter.

The edger isn't meant to trench; you should rent a trencher for that purpose.

And the string trimmers aren't meant to mulch leaves but they do a bangup job at it. Sometimes it's ok to think outside the trench a little bit when it comes to using our tools.

^^ with Mike on this one.  Sometimes we all need to improvise, not only to save money, but because we can.

Why not.  As long as you are not creating unreasonable danger to yourself or others worse thing that happens is you break the tool.  But that is the chance you take whether hammering with a wrench, using a screwdriver as a chisel or pry bar, or using an edger as a trench digger.

Plus...I'm not for someone abusing and breaking a device not meant for that purpose and then trying to get it replaced under warranty...:(

Absolutely; manufacturers who honor warranties on misuse passes the cost to all consumers. A form of Socialism.
