    I want to change the hydro fluid and filter on my Super Z. I wasn't given a manual when I purchased it. Could you give me the steps to changing the fluid and filter? Thanks in advance.

    Here is the information from a owners manual....
    Check oil level in hydraulic system after every 50 hours
    of operation or weekly, whichever occurs first. Check more
    often if system appears to be leaking or otherwise
    Fluid level should be 1” from top of reservoir. Use only
    SAE 10W40 SG, SF/CC, CD service motor oil.
    Change hydraulic system filter element (Fig. 4-5) after
    first 50 hours of tractor operation, then replace filter and oil
    in reservoir every 500 hours thereafter. When changing
    hydraulic oil use 1/2 unit (approximately 3.5 oz.) of Lubrizol
    additive (Hustler P/N 027912). This additive, available
    from your Hustler dealer, will increase the performance life
    of the hydraulic system components.
    The system filter is located directly in front of the
    hydraulic reservoir. A standard oil filter wrench is used to
    change filter, threads are right handed. Use a Hustler
    approved filter element only.
    IMPORTANT: Prefill the filter element with clean oil,
    before installing, to prevent drawing air into the system
    1. Fill the filter element with clean system oil. Smear a
    light coating of oil on upper surface of rubber seal.
    2. Install the filter element on base. Tighten the oil filter
    by hand until the filter seal makes contact with the
    filter head, then tighten an additional 3/4 - 1 turn with
    an oil filter wrench. — DO NOT OVERTIGHTEN.
    3. Start tractor engine and let run at approximately 2/3
    throttle for a few minutes to work any trapped air out
    of the system before engaging the steering control
    4. Stop the engine and check the filter and connections
    for leaks.
    5. Check the hydraulic reservoir for specified oil level.
    Add clean oil as necessary.
    Clean or replace hydraulic reservoir cap annually. Cap
    may be cleaned by dipping in or flushing with cleaning
