    There should be a quill adjustment facing up next to the reservoir. Will be a flat head screw. Now this will not help raising. Most likely you have a clogged filter but other causes are worn pump, improperly adjusted relief valve or weak motor.

    Towman, go to Fisher's website, parts & service link, then service publications library, then owners manuals, then snowplows, then MM2 system (with Indexed Jack Stand) LD, RD/HD, XBLADE & MC Series manual,(5th manual down the list). Pg. 16 will show & tell you what you want to know on how to adjust lift piston drop speed. Hope this helps.

    When was the last time you changed the fluid and the clogged filter that kimber mentioned? It is always a good idea to change the fluid every year before the season starts.I usually do mine in the fall.Its like changing the oil in the snowblower before the season.Any bit of water that is in that fluid could freeze and cause a problem.Your best bet is to drain the fluid,remove the reservoir change the filter kimber mentioned,and also clean any metal shavings at the bottom of the reservoir (there is a magnet on the bottom) and reinstall.Fill with fluid and I would also disconnect the hoses from the piston and drain out and old fluid that could be in them and run the plow until fresh fluid comes out of the hose then put hoses back on.Then I would do your adjustment
