    I used my plow yesterday and the day before and everything was fine. I went to hook up to it tonight and went to lift it up and it began to make a loud screaching noise and slowed down. It moves side to side perfectly and was operating perfect the other day. Anyone have any ideas?? Im hoping i can have it figured out by tomorrow.

    What do you have? If it's a MM2 is it belt driven hydraulic or self contained electric? Either way, it sounds to me like you're hearing a belt squeal. If it is belt driven, check the belt tention...if it's self contained and the belt is squealing, you may need a new belt and / or tentioner OR the alternator may be on the way out. Post more info...

    MM2's are a self contained unit and don't have belts. If there is a belt squeaking then it would probably be from the alternator with the extra load.
    Mine makes a loud slam every now and then. I thought it was the chain catching, still haven't figured it out. But it jumps and makes a bang sometimes, usually after I have plowed into a bank and the plow has lifted by itself.That's why I'm thinking it's the chain. Check and make sure nothing is catching maybe??

    I had a similar problem with my 8' x-blade. I dropped the fluid resevoir and replaced the return screen and installed the redesigned pickup filter assembly. It seemed like my pump was airating with heavy loads, even side to side at times. New kit comes with all the o-rings needed including a new pump o-ring. good luck.

    from that description it sounds like low fluid or somethings blocked in the pump. screeching is typical when its just sucking air, and stalling, well that can happen with low fluid. good luck. seems odd to do it all of a sudden, usually something like that slowly creeps up on you as fluid usually leaks slowly.

    There was a problem with pick-up tubes falling off at a certain period which will give that symptom,pull the resivoir off,it'll probably be laying at the bottom of the tank.
