    Default 6640 SLE Hydraulic Pump

    I am having trouble with the light coming on after the tractor warms up. Any ideas or where I can find a pump? Thanks! Allen Clark Erieville, N.Y.

    You are looking to buy a pump or looking for the pump on the tractor?
    The first thing I would do is to change the hydraulic filters. There are three filters coming off of the pump on the right side just in front of the rear axle. The horizontal filter is the charge pump filter. The small vertical is steering and the large vertical is lift pump intake. I would change all three if you can't remember the last time they were changed. Changing the hydraulic oil wouldn't be a bad idea either.
