    My 773 Bobcat overheats after about 20 minutes of using it to blow snow with a Bobcat 250 Snow Blower. It used to overheat after using it for over an hour. I topped off the anti-freeze before starting. The motor oil was full & hydraulic oil is in the middle of the sight glass.
    Thank You, Goodearth13

    I'd start with verifying the actual motor temp using a temp gun on the block. Could just be a bad sending unit.

    I start whit a visual ispection on the radiator cells, a simple power wash may do it..

    I'd start with the basics. Coolant level and concentration, airflow through the coolers is unobstructed and fan speed is correct.

    Are you sure its the engine that is over heating? I had a old Bobcat 630 that would get way hot and actually stop moving due to the main hydraulic pump being worn-out. The fact that you say you are having more issue while using the snow blower really make me think you may have pump issues rather than engine issues.
