    Speedcaster (also referred to as Conventional): When you take the plow off between storms, the headgear (lights, lifting frame, etc.) stays on the truck.

    MinuteMount 1 & 2: When you take the plow off between storms, the only thing that's left on the truck are mounting tabs.

    Most MinuteMounts are electric over hydraulic. But there was a transitional period when you could still get belt-driven hydraulics with a MM set-up.

    ATF went out with the dinosaurs......:dizzy:

    Do your self a favor and use a quality hydraulic fluid with at least a w32 rating or better yet use boss, meyer, or some other high quality fluid even the cheep blue stuff is better.

    It will flow better at lower temps which will result in your motor drawing less amps. It will not clog your filter with wax when it gets cold.

    Don't forget to clean your filter too.

    The belt-driven pumps were designed and manufactured when Fisher still had a contract with the Dinosaur Local 133. (Those T-rex fellows really had a tough time welding with those tiny arms!)

    It's always toasty warm under the hood, so low temp is no problem.

    Motor drawing less amps??? Not unless it's a Toyota Prius. :p
