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
