hmmm sounds like you have a problem.maybe they followed some doe's back over there.coyotes could be a reason they moved.has anyone run the woods on atvs?maybe some people have been running it.hope every thing goes right for ya and they come back before deer seasons out.
4 wheelers and snowmobiles usualy dont scare deer off. Most of the time the will just stand there untill ya shut off the engine , then they bolt . But even then its usualy only 20 ft or so behind some cover.
