    I'll take the high road, and say that you should put the pin in whatever hole causes the a frame to be parallel to the ground.

    If you know what I mean.....lol

    yeah, that's what the manual says, but for some reason it just does a suck job of scraping the snow.
    Thanks.

    Are you running shoes? Also, what kind of cutting edge are you running. Can you post some pics of the setup from various angles?

    no shoes. the plow is only a year old and didn't get much use. It has a ploycarbonite edge on it. I even added an additional 100 lbs of weight. Maybe edge hasn't "sharpend" enough yet.. I've thought about taking edge off and see if that makes a difference.I'll have to send pics later right it's raining cats. dogs and ice.
    Thanks

    I would not add extra weight... You measure the height of the push plates on the truck when the truck is properly ballasted and sitting on a level surface. Refer to the manual as to what hole for the height you measure. Also, keep in mind that the attack angle of the cutting edges arent that aggressive especially on the SD series. It will push snow but don't expect it to scrape down to pavement on icy hardpacked surfaces.

    Manual just says to park truck on level surface and pick hole which puts frame is closest position to level.Which is fine, but what if it is "in between" holes do you make top of plow pitch forward away from truck or do you make it fall back towards truck?
    Thanks

    Whatever makes it closer to level.... The further forward the plow leans the easier it will trip.... The further back the harder..

    And if the a frame is not level, the blade wont fully contact the ground at full angle.

    We know, but thats one of the side affects of a not-level a-frame.

    felt like you had to say something sierra? Don't forget to mention possible tire size? are they snows? all seasons, 16, 17 18"? Give me a little credit.

    Bottom. That is going to give you greatest attack angle on a 1500. If you want to experiment than add another hole under it but you'll have to watch clearances everywhere else if you do that.
