    Hi,

    I am not in the industry but use a Grashopper 721D front mount mower and am having problems. I am looking for help.

    Engine starts fine
    Blades turn fine when clutch is engaged


    Problem:

    The mower can no longer move forward. While both lever push forward, the right side doesn't engage with the transmission.

    I am a newbie and not a mower expert. So any feedback will need to be in layman's speak.

    Thanks in advance.

    You have knuckle joints on your stearing linkage. Pop up the seat and compare the one side with the other. Move the steering lever and if its not moving the valve on the hydro pump something broke. It should be easy to spot what's wrong if you following the linkage.

    Thank you... after thinking it was the right hydro pump - $700.00, I realized that one of the belts was missing in the drive assembly. There is a double pulley off the drive shaft and only one belt. HA! Seems the part will only be about 15 bucks.

    THanks,

    If its the old 721d's the pumps are easy to work on and parts are cheap.
