    Hi, does anyone know if an older 257 Cat has continuous flow hyd?

    if it has the thumb proportioning switch on the right hand joystick, you should be able to lock it in the flow position.

    Get your serial # and call Cat. They'll tell you anything you want to know about the options on your machine.

    The lock is on the left hand joy stick. I can't remember if it's the lower left or right button. If you have the thumb proportioning knob you slide that to max flow then press the lock open button. You should see a green icon come on by your ignition key
