I wouldn't take chances with coyotes.One can easily pump a single stake out of the ground.I used to set a few 1 1/2's for fox when I was running out of clean coyote traps.I ended up catching several coyotes and held every one,though one had the stake pumped halfway out of the ground and that ground was frozen hard as concrete.
I would double stake and make sure the jaw ends are turned up.If it were earlier and you hadn't dyed and waxed them,I'd say get someone to bubble the jaw tips.If you have coyotes around,I would take the fur check money and get some bigger traps.
I don't know what kind of hammer you have but driving double stakes,a heavy hammer like the "sodbuster" that dealers sell is worth it's weight in gold.You may have already but make sure that the contact are of pan notch and dog are scraped clean of ALL wax-just that little contact area.Put some tension on the pan and make sure it's level.
I double stake like this with 1/2"x18" rebar stakes.Cut a 12" piece of 1/8" cable and 2 double ferrules for the loops.It finishes up about 6" long and has a little flex to it,plus a little scissor action if the ground isn't froze.Double stake swivels are good also.
