Topband: Edger for burying ground radials ?

[Ed Stallman]

I would like to know if anyone has used an edger to cut small groves 
in the ground for burying radials ? If this will work , I'm going to 
need something heavy duty. something like what's in the link below 
...because I have allot of radials to bury at least an inch beneath 
the soil, 2 would be better. I have this bahiagrass in my pasture and 
this stuff is tough . From reading the add's on these edgers, most 
say they will cut up to 2.5 inches in depth. I've never  had the need 
for an edger, so I'm asking will this make  a fairly clean cut to lay my wire?

I know their are better way's but I don't have a tractor and I can't 
staple them to the ground .

what do y'all think, will this work ?
