    I just purchased a used sst16 John Deere riding mower.....did fine when I test drove it home and used it about 30 minutes.....and all of a sudden it will not steer at all forward, and sometimes it won't steer backwards...also shuts off sometime when put in reverse...I do not have a manual or any literature on the mower.
    Any help would be appreciated!
    Thank you,:)

    These machines are fairly complicated so you reall need to get a JD Tech Manual for it (see below). Problem can be either with electric or vacuum system but I'll try to help with easy and cheapest things first until you can get a Tech Manual.

    Propel Switch Adjustment:

    1. Park machine safely with park brake locked.

    2. Locate the proper switch through the sight windows in the side frame. The right wheel may require removal from the machine.

    3. If adjusting the top switch, fully depress the forward pedal 2 or 3 times and let the pedal return to neutral on its own.
    If adjusting the bottom switch, fully depress the reverse pedal 2 or 3 times and let the pedal return to neutral on its own.

    4. Loosen the appropriate nut (B) holding the switch to the side of the frame.

    5. Adjust the switch bracket location with the tabs to set the gap (0.040“) between the switch’s metal plunger and the lever associated with the switch.

    6. Tighten the nut holding the switch while holding the switch bracket stationary.

    7. Check the switch gap plunger. Repeat as necessary. With the switches adjusted properly, a slight “click” (switch closing) can be heard almost immediately when depressing the foot pedals.

    For a tech manual: Call the JD Parts Resource Center
    @ 1-800-522-7448. Tell them you want the SST16 or
    SST18 Technical Manual on CD, both machines are
    covered in the same manual. Have your machine's serial
    number handy because there are different publications
    for 2 different serial number ranges. The cost is
    $40.00 + S&H.
