    After 18 hours of plowing with my standard duty fisher it finally crapped out on the last driveway (what timing eh?) It does not move at all. When I press the controller in either direction or up it just sounds like a motor racing and when I let go of the direction it stops. It is 2 years old

    Sounds like the pump needs to be rebuilt. Maybe a gasket or something let go? It sounds like it powers up, but does not move any fluid... Hence, no plow movement...

    Couple of thoughts as to how I got to this conclusion. The pump "racing" means that there's no resistance... It's not "pushing" any fluid around. If it were a stuck valve or something like that, it would sound like the plow motor is bogging down...

    I brought this to Madigans, a dealer and they said it was covered under warrant, 2 years. They replaced the pump and said that fisher had a bad batch of pumps during this time. Interesting. amazed I diddnt have to pay a dime.
