    I have noticed that a lot of big trucks (ex. 10 wheel dumps, etc) have the plow frame attached to the front axle aswell as the truck frame. Obviously it's fine, because I see it all the time, but why would you want your plow to push against your axle?:confused:

    We never have our plows connected to front axle, haven't heard of that before; even when I worked for CDOT none were set up to attach to the front axle- how does the suspension work being attached to the plow?

    I guess the suspension still flexes. Most of the city trucks here have the frame mounted that way.

    If you can get any pics of that setup it would be appreciated!

    it takes a lot of the weight off the suspension and puts it onto the tires and its a low pushing plate...you mainly only see this on macks

    Nonsense, it's just a simple and effective way of transferring the pushing load, so long as the dummy behind the wheel doesn't send the plow frame through the oil pan on a bridge. Frame pivots at the bumper as the suspension moves. I don't think it's used on AWD setups.

    Hvy truck frame is ~3' off the ground, much more metal and work required to transfer the load from the point of contact -- cutting edge -- up to that height.

    some of those old oshkoshes have what looks like part of a bridge welded under the truck for the plow to mount to.

    it depends on the plow manufacturer. On the flink/baker units we use they tie into the frame not the axle(one of the trucks is awd).Attaching to the axel also makes it more of a universal mount.
