    Simple reason for that, Homesteader/Suburbanites do not have down pressure. You have to buy a Snoway if you want DP.

    Because that it exactly what it is doing.....floating.

    scrape lock

    When you lift the blade does the cylinder collapse or are you just lifting the slack in the mount? I believe that you can adjust the scrape lock although I never have.

    scrape lock

    scrape lock is designed to lock the cyclinder down otherwise the plow would be in constant float.

    Locked as in no up or down movement.....

    it allows for downward movement. Upward movement happens only when under too much pressure.

    The scrape lock hydraulic line is the one that comes off the tank and runs directly to the cyclinder. That line, i'm assuming, allows fluid into the top of the cylinder when extended to keep the cyclinder from collapsing. I would assume that there is a pressure relief which is what is adjustable. When you put it in float mode the pump allows fluid to back flow allowing free up and down motion!

    Again, just my assumption based on the design!

    The lower speed of the plow is adjustable. I'm not sure if the relief valve in the scrape lock is adjustable or not, I've have never paid any attention. You would make the hydraulics work a lot harder if you were to tighten it down as the unit works against the PR every time it lifts. If your units scrape lock is not operating it could be a bad check valve or a bad PR valve, both are located on the cylinder

    I still would not mess with adjusting it differantly if it works. Extra wear on the system.

    I'll run it this season, and see how it does...

    Upward movement only happens when under to much pressure?? Is lifting the blade up by hand considered to much pressure??..... reason why I ask is if scrape lock is suppose to lock the blade from moveing up or down, then mine needs to be adjusted or repaired...
