Push the corn down? Hardly.
Deer like to bed in corn. Just because you push lanes down doesn't mean that smart old buck is going to get up and walk out in the open.
Let it stand. Hope for moderate wind. Take a light carbine...like a Ruger Deerhunter 44Mag or a open-sight muzzleloader...or anything with iron sights...and still-hunt that corn. Go across the field row by row, then move up 30 yards (a bit less or more depending on the condition of the corn) and repeat.
I've killed a ton of deer this way. Typically where I live now the corn is down by gun season so I don't get the chance. But I've done the same thing with a bow, it just harder to get a good shot angle when they are bedded.
