Hi everyone & thanks in advance for any advice given to my issue. Ive had a fisher straight blade MM2 for about 7-8 years. Works great however, Im trying to slow down the plows drop speed as it currently slams down really hard and fast. No resistance whatsoever. Ive tried turning on the quil screw (which is currently raised high & showing alot of thread on the screw). It seems completely seized / stuck. It wont turn at all. Has anyone had this issue or have an idea of how to fix it or get it to turn ? I'll post a picture shortly if I can upload showing its position. My plow mechanic says I need an entire new assembly, and Id rather not have to spend all that $$.
