    Looking for a site we can download a repair manual for our Gravely, the deck lift inop. Model 992051, Serial # 000157

    I suspect the culprit is in the picture and fingers crossed couple gears and good cleaning IMG_4106.jpg will get us back in operation.

    If anyone can help we would be very appreciative.

    Thanks, smokeless

    Thanks, downloaded service manual. Title refers to 250 and 260: however, appears to be very similar if not identical. At first blush could not identify reference to charge pump, will also check parts manual. Thanks, this will get us started.

    I really appreciate the link, helps us allot to understand and work on our machine; however, i did not see what we are looking for.

    If available, we would like an exploded view of the charge pump that regulates the raising/lowering the deck. Hoping their are a set of pump gears we could replace AND we are assuming they are faulty.

    So, any leads please would be appreciated and helpful

    Thanks

    I know this is probably not your unit, but take a look at the internals and description of charge pump. May give you some insight
