My fisher HD2 7'6" straight blade purchased new in July 2019 on a 2017 Ford F350 diesel is VERY difficult to install (mount) It is dealer installed the mounting pins refuse to engage without much jostling, jacking (floor jack) and cursing average mount time about a half hour. I have taken the truck/plow back to the Fisher dealer and he was able to dismount and re-mount the plow with little difficulty This is not my first Minute Mount Plow. the last one mounted and dismounted with ease. So I know how its supposed to work SOMETHING is wrong. Anyone having a similar problem? Any help would be appreciated.
